Geographically, Svalbard and Bear Island
belong to NW Europe, and records from these
islands ought to be included in the list. However,
as only one Trichoptera species, Apatania zonella
(Zetterstedt, 1840) is recorded from these islands
(e.g. Lack 1933 (as A. arctica (Boheman, 1865),
Bertram & Lack 1938 (as A. arctica), Decamps
& Voisin 1971, Solem et al. 1977), they are not
treated separately in the list.
The present check-list is intended to present
current views on Trichoptera systematics based
on larval as well as adult morphology. In contrast
to the list of Svensson & Tjeder (1975c), the fami-
lies here are listed in accordance with current con-
cepts, i.e. in a general trend from primitive to
derived (e.g. Wiggins 1982, Barnard 1985).
Within the different families, however, tribes,
genera, and species are listed in alphabetical
order.
The list is based on earlier publications, study
of museum- and private collections and personal
communications. Reference is given to relevant
papers not mentioned by Svensson & Tjeder
(1975c) as well as to more recent papers. Annota-
tions are given for those species with italized num-
bers.
TAXONOMIC NOTES
Family-group taxa
We have accepted the families Ecnomidae and
Goeridae. In treating Ecnomidae as a separate
family and not as a subfamily of Polycentropodi-
dae, we agree with Lepneva (1964), who based
her opinion on the distinctive larval morphology.
The family Ecnomidae has been widely accepted
(e.g. Malicky 1973, Botosaneanu & Malicky
1978, Edington & Hildrew 1981, Tobias & Tobias
1981, Wiggins 1982, Barnard 1985).
The Goeridae are considered a separate family
by Ross (1944), Malicky (1973) and several subse-
quent authors, who based their opinions on both
adult and larval morphology. It should be noted
however, that Wiggins (1973b, 1977) has treated
the Goeridae as a subfamily of the Limnephilidae,
the Goerinae.
Genus-group taxa
Eomystra Martynov, 1934 and Synafophora Mar-
tynov, 1927 are considered to be synonyms of
Glossosoma Curtis, 1834 in accordance with
Botosaneanu & Malicky (1978) and Tobias &
Tobias (1981).
According to Kimmins (1966), Oxytrichia
Mosely, 1939 is a synonym of Oxyethira Eaton,
1873.
Nielsen (1981) and Schuster (1984) recognized
Ceratopsyche Ross & Unzicker, 1977 and Hy-
dropsyche Pictet, 1834 as separate monophyletic
genera based on characters in the larval, pupal
and adult stages (genital structures of both males
and females). Ceratopsyche includes the Hy-
dropsyche morosa-species group, represented by
two species in Europe. We have accepted the
proposals of Nielsen and Schuster, although there
are differences of opinions concerning the splitt-
ing of Hydropsyche (see Schefter et al. 1986).
Based on larval characters (the alignment of coxal
combs on mesothoracic legs), Solem (1981) sug-
gested that Agrypnia crassicornis (McLachlan,
1876) should be transferred to the genus Agrypne-
tes McLachlan, 1876. We have followed the sug-
gestion made by Solem, although several authors
merely regard Agrypnetes as a synonym of Agryp-
nia (e.g. Malicky 1983, Barnard 1985).
In a phylogenetic study of the genera of Brachy-
centridae, Flint (1984) only recognized five
genera within this family, thereby treating Oli-
goplectrum McLachlan, 1868 as one of five sub-
genera within the genus Brachycentrus Curtis,
1834. We have decided to follow this synonymy in
the present check-list.
Schmid (1951) placed Anabolia dubia Ste-
phens, 1837 in the genus Ironoquia Banks, 1916
based on characteristics of the adults. However,
by comparing preimaginal descriptions of Iroreo-
quia parvula (Banks, 1900) and L punctatissima
(Walker, 1852) from North America (Flint 1960)
with descriptions of/. dubia (e.g. Lepneva 1966),
Svensson & Tjeder (1975c) concluded that larvae
of I. dubia differed from those of /. parvula and I.
punctatissima. Moreover, they found it of great
importance that pupae of I. parvula. differed
from those of /. dubia (in particular by the
absence of gills in I. parvula and presence of gills
in I. dubia). Based on these literature studies,
they concluded that I. dubia was not an Irono-
quia. Instead they placed it in'a "Gen. incertum".
We studied larvae of /. dubia and found that they
perfectly fitted the larval diagnosis of Ironoquia
given by Wiggins (1977), and we do not consider
the question of absence/presence of pupal gills to
be of importance. Larvae of I. parvula inhabit
167
temporary pools, having been found to leave a
pool in late spring presumably in the final instar,
and to crawl beneath fallen leaves around the
edge. There, they evidently aestivate as larvae
until late summer, when pupation occurs (Flint
1958, Wiggins 1973a). As pupation takes place in
a terrestrial environment, pupal gills are of no
advantage and therefore probably absent in I.
parvula, whereas I. dubia pupate in slow-flowing
streams among leaves (Ulmer 1909), where
presence of gills is an obvious advantage.
Eaton (1867) based his generic name Bereodes
on "Berea", a misspelling of Beraea Stephens,
1833. Nearly all subsequent authours have used
the spelling Beraeodes, which according to Bar-
nard (1985) "is regarded as a justified emenda-
tion".
The genus Athripsodes Billberg, 1820 has been
divided into two genera, Athripsodes and Cera-
clea Stephens, 1829 in accordance with Morse &
Wallace (1976).
The genus Triaenodes McLachlan, 1865 is divi-
ded into two genera, Triaenodes and Ylodes Mil-
ne, 1934 in accordance with Manuel & Nimmo
(1984).
Subgenera are omitted in the present list. It
should be noted however, that Svensson & Tjeder
(1975c) gave subgeneric rank to Apatelia Wal-
lengren, 1886, Parapatania Forsslund, 1934 and
Gynapatania Forsslund in Forsslund & Tjeder,
1942.
Species-group taxa
Hydroptila simplex Nielsen, 1948 has bcen dele-
ted from the present list, as the only known speci-
men no doubt represents an abnormality (see also
Wiberg-Larsen 1985). We do not find it possible
to establish formal synonymy for H. simplex.
Plectrocnemiella carelica Nybom, 1950 has
been deleted from the list, as the only known spe-
cimen (a male) according to Dr. H. Malicky (Ny-
bom in litt. ) represents an abnormality. As indica-
ted by Hulden (1984), it should be regarded as a
synonym of Plectrocnemia conspersa (Curtis,
1834).
There is much controversy in the literature
regarding the taxonomy and classification of Apa-
tania species, especially of the A. muliebris- and
A. zonella groups.
Numerous species or subspecies of the A.
muliebris group are recognized in NW Europe
(see Nielsen 1950, 1969, Schmid 1954, Svensson
& Tjeder 1975c). However, as the A. muliebris
group reproduces by parthenogenesis only, each
individual female is reproductively isolated, and
according to the biological species concept, a dis-
tinct species (Solem 1985a). According to Solem
(1985a), Norwegian specimens of A. muliebris
McLachlan, 1866 are very variable with respect to
the morphology of female genitalia. Actually,
specimens referable to various subspecies, viz. A.
m. muliebris McLachlan, 1866, A. m. cimbrica
(Nielsen, 1950), A. m. jemtlandica Nielsen, 1969,
and A. m. kolteriana Nielsen, 1969, occur togeth-
er in streams in the Dovre mountains in Central
Norway. We therefore agree with Solem (1985a),
that recognition of several distinct species or sub-
species in the A. muliebris group is unwarranted.
The A. zonella group comprises A. auricula
(Forsslund, 1930), A. dalecarlica (Forsslund in
Forsslund & Tjeder, 1942), A. forsslundi Tobias,
1981, A. hispida (Forsslund, 1930), A. stylata
Navas, 1916, and A. zonella (Zetterstedt, 1840). In
A. zonella, parthenogenetic reproduction seems
to be the main reproductive strategy; males gener-
ally make up less than 1 % of the populations, al-
though the frequency of males in some popula-
tions might be higher (Lack 1934, Schmid 1954,
Corbet 1966, Solem 1985b, Andersen & Wiig
1987). Parthenogenesis is probably also the main
reproductivc strategy in ohter species in the A.
zonella group. Therefore, the A. zonella group
shows similar taxonomic problems as the A.
muliebris group and is difficult to handle because
of the wide variation in morphological features
(Solem 1985a). During a study in the Dovre
mountains in Central Norway, Solem (1985a)
found it difficult to distinguish the taxa A. dalecar-
lica and A. forsslundi, as he found all kinds of in-
termediate forms. Further, Andersen & Wiig
(1987) demonstrated clinal shape variation in
West Norwegian A. zonella. However, pending
further evidence we have decided to accept the
many species currently recognized in the A.
zonella group.
Botosaneanu & Malicky (1978) listed Apatania
majuscula McLachlan, 1872 from Norway and
from their geographical regions 21: tundra and 23:
taiga, which includes Finland. However, these
records cannot be confirmed (see Solem 1985a).
A. majuscula was recorded from the Arkangel'sk
region and from eastern Siberia by Lepneva
(1966).

NOTES
5. Not recorded in Finland (Huld6n et al. 1977).
Svensson & Tjeder (1975c), citing the late Dr. A.
Nielsen (in litt.), suggest that the species is extinct
in Denmark. However, it has just recently been
recorded from Skjern A at Tarp.
9. Svensson & Tjeder (1975c) stated that the spe-
cies is probably extinct in Denmark. However, it
still occurs in several streams although it has
disappeared from many localities.
10. According to Marshall (1979), the abdomen
of the type specimen, which has been crudely fig-
ured by McLachlan (1880), has been lost. Malicky
(1983) omits the species from his atlas of Euro-
pean Trichoptera. Moreover, Hans Malicky (in
litt. ) informs us that he has seen one A. cognatella
from Siberia (in the Martynov collection), which
was identical with A. multipunctata. He was not
able to find any information in the literature
which would allow a distinction between the two
species. He therefore suggested that A. cognatella
is a synonym of A. multipunctata. One of us (Wi-
berg-Larsen) examined Swedish and Danish
material of Agraylea and found distinct differen-
ces between males of A. cognatella and A. multi-
punctata (Figs. 1-4). Tobias & Tobias (1981)
also recognized A. cognatella and gave figures of
both males (closely resembling the present fig-
ures) and females. Judging from their figures,
females of A. cognatella differ from A. multipunc-
tata by the presence of excision dorsally on poste-
rior border of segment VIII and the absence of a
distinct ventral sclerite of segment VIII.
14. Re-established as Danish by Wiberg-Larsen
(1985).
15. Recorded in Denmark by Wiberg-Larsen
(1985).
17. According to Marshall (1977), H. kimminsi
Mosely, 1930 is a synonym of H. occulta (see also
Nybom 1980). Recorded in Norway by Andersen
& Tysse (1985) (see also Marshall 1977) and in
Sweden by Gullefors (1985).
23. Not recorded in Finland (Hulden et al. 1977).
Ithytrichia clavata was described by Morton
(1905) based on North American material. Tjeder
(1930) identified the species from Swedish mate-
rial, as he was not "able to find the slightest differ-
ence" between a Swedish specimen and North
American specimens borrowed from K.L. Mor-
ton. However, Ross (1944) and Lazare Botosa-
neanu (in litt.) express doubts about the identity
of northern and western European specimens.
Pending further evidence, we have decided to
retain I. clavata in the present check-list.
26. Recorded in Norway by Andersen (1975).

28. In describing O. boreella, Svensson & Tjeder
(1975b) did not study the type-specimen or other
material of the closely related O. falcata. How-
ever, Kelley (1984) has studied relevant type-speci-
mens and considers O. boreella as a valid species,
distinct in both males and females.
29. Recorded in Denmark by Wiberg-Larsen
(1985).
31. Recorded in Denmark by Wiberg-Larsen
(1985). Inadvertently not included in the check-
list of Finnish insects (Hulden 1984) (Pekka Hiili-
virta in litt.).
32. Only larvae of Oxyethira have hitherto been
recorded in the Faroes. However, current tax-
onomy does not permit separation of larvae of
Oxyethira species.
34. Nybom (1983) described this new species
based on Finnish specimens.
38. Recorded in Denmark by Wiberg-Larsen
(1985).
40. Recorded in Denmark by Wiberg-Larsen
(1981, 1985) and in Finland by Hiilivirta (1982).
42. Recorded in Norway by Andersen (1979).
Norwegian populations belong to ssp. trifida
Andersen, 1983 (see Andersen 1983).
43. According to Wiberg-Larsen (1980b), the
species is probably extinct in Denmark. However,
181
well as A. dalecarlica, might be a synonym of A.
zonella.
108. Wolfgang Tobias (in litt. ) informs us that he
has taken some specimens of probably new Apa-
tania species, belonging to the A. zonella group, in
Varanger, NE Norway.
109. Recorded in Norway by Solem (1978) and
Andersen (1979). However, the species has pre-
viously been recorded in Norway (e.g. Brekke
1946, Loken 1966), but it was not included for
Norway by Svensson & Tjeder (1975c).
111. Scandinavian populations belong to ssp.
scandinavica Forsslund in Svensson & Tjeder,
1975. There seems to be doubts about the true
identity of this subspecies (see Svensson & Tjeder
1975c).
116. Wolfgang Tobias (in litt. ) informs us that he
and Dagmar Tobias have taken this species in
Norway (Pasvik, NE Norway).
130. Recorded in Finland by Nybom (1980).
133. Recorded in Norway by Andersen & Soli
(1987).
142. Recorded in Norway by Solem (1985b).
145. Not mentioned from Denmark by Svensson
& Tjeder (1975c), although it was recorded in this
country by Esben-Petersen (1938) (see also
Wiberg-Larsen et al. 1980).
147. Wolfgang Tobias (in litt. ) informs us that he
and Dagmar Tobias have taken this species in
Norway (Pasvikelv, NE Norway).
148. L. minusculus (Banks, 1907) was recorded
as new to Europe from northern Norway by
Tobias (1976b) (see also Botosaneanu & Malicky
1978). However, according to Malicky (1979), L.
minusculus is a synonym of L. dispar.
150. Recorded in Norway by Andersen (1975).
174. Recorded in Denmark by Mogensen (1973)
and Wiberg-Larsen et al. (1980).
175. Malicky (1979) placed L. scalenus Wallen-
gren, 1891 in synonymy with L. subnitidus.
176. Recorded in Denmark by Wiberg-Larsen et
al . ( 1980) .
189. Not recorded in Finland (Hulden et al. 1977).
190. Recorded in Iceland by Svensson & Tjeder
(1975c), based on previously unpublished materi-
al. Same year recorded as new to Iceland by Gisla-
son (1975).
194. Not mentioned from Denmark by Svensson
& Tjeder (1975c), although the species was record-
ed in this country by Esben-Petersen (1933) (see
also Wiberg-Larsen et al. 1980).
197. Not mentioned from Denmark by Svensson
& Tjeder (1975c), although the species was record-
ed in this country by Esben-Petersen (1933) (see
also Wiberg-Larsen et al. 1980).
200. Recorded in Norway by Andersen (1980).
204. Recorded in Norway by Solem (1967,
1985b).
212. According to Bo W. Svensson (unpubl.
manuscript), previous records of A. filicornis
(Pictet, 1834) in Denmark (e.g. Esben-Petersen
1916) actually refer to A. reducta.
215. According to Ola Nybom (in litt.) taken in
Russian Karelia.
227. Recorded only once in Finland (Helsinki) by
Nybom (1980), who suggests that the specimens
(6 females) are accidental immigrants from the
Baltic. According to the late Dr. A. Nielsen
(Svensson & Tjeder 1975c) "the known popula-
tion in Denmark is now threatened by water pol-
lution". However, there actually exists several
populations of L. tineiformis in Denmark (espe-
cially in Zealand and Funen), although it has
disappeared from several lakes and ponds due to
eutrophication.
231. Recorded in Norway by Andersen (1975).
236. Known only from two Danish localities
(Hannerup So, north of Hobro, NE Jutland, and
Plovskxr Mose, Ebberup, Funen).
240. Recorded in Norway by Tobias (1976a).
242. Recorded in Denmark by Wiberg-Larsen
(1981). The species is deleted from the Finnish
fauna by Hulden et al. (1977), but according to
Ola Nybom (in litt.) there are several Finnish
records (see also Hulden 1984).

... In 1889 and 1890 P.B. Mason and F.A. Walker, respectively, made short stopovers in the Faroes on their way to Iceland and collected insects, but no new species were added to the Faroese species list (McLachlan 1889; Walker 1890a, 1890b). A few years later the Danish botanists C.H. Ostenfeld and E. Warming also collected insects in the Faroes, and one new record of Trichoptera species Potamophylax cingulatus (Stephens 1837) was recorded by J.C. Nielsen (1908) (as 'Anabolia areata Kol.' which Henriksen (1928) corrected to 'Stenophylax latipennis Curti.' which, in turn, later authors (Andersen & Wiberg-Larsen 1987;Solem & Gullefors 1996) reported as the syn. latipennis auct., nec (Curtis, 1834). ...
... He also recorded an uncertain Oxyethira flavicornis (Pictet 1834) (as its syn. O. costalis Eaton, 1873 et auctt., nec (Curtis, 1834)), but only the genus can be assigned with certainty (Andersen & Wiberg-Larsen 1987). ...

In this paper the literature on Trichoptera in the Faroe Islands is reviewed and occurrence of species in recent research on freshwater insects is added. The first record of Trichoptera dates from 1782, without any recognisable species. Today, 20 species are known from the islands, but their frequency of occurrence differs between the Northern Islands and the other islands. A difference in topography of the island groups has previously been hypothesized as an explanation, and data presented in this paper support this hypothesis.
... In Fauna Europaea Malicky (2012) lists this taxa as a valid species with distribution in Finland, Norway and Sweden, but notes that " Brauer's species is misapplied for the species occurring in Fennoscandia."

... Remarks. The Apatania zonella (Zetterstedt, 1840) group of species contains predominantly parthenogenetic species of which several were listed for Norway by Andersen & Wiberg-Larsen (1987). However, when compiling the latest checklist of Norwegian Trichoptera species Solem & Andersen (1996) treated A. zonella in a wide sense omitting most of the other species in the group as we at that time deemed it necessary to re-examine available material to confirm identification before listing them. ...

Records of 108 species of Trichoptera from Finnmark, northern Norway, are presented based partly on material collected in 2010 and partly on older material housed in the entomological collection at the University Museum of Bergen. Rhyacophila obliterata McLachlan, 1863, must be regarded as new to Norway and Rhyacophila fasciata Hagen, 1859; Glossosoma nylanderi McLachlan, 1879; Agapetus ochripes Curtis, 1834; Agraylea cognatella McLachlan, 1880; Ithytrichia lamellaris Eaton, 1873; Oxyethira falcata Morton, 1893; O. sagittifera Ris, 1897; Wormaldia subnigra McLachlan, 1865; Hydropsyche newae Kolenati, 1858; H. saxonica McLachlan, 1884; Brachycentrus subnubilis Curtis, 1834; Apatania auricula (Forsslund, 1930); A. dalecarlica Forsslund, 1934; Annitella obscurata (McLachlan, 1876); Limnephilus decipiens (Kolenati, 1848); L. externus Hagen, 1865; L. femoratus (Zetterstedt, 1840); L. politus McLachlan, 1865; L. sparsus Curtis, 1834; L. stigma Curtis, 1834; L. subnitidus McLachlan, 1875; L. vittatus (Fabricius, 1798); Phacopteryx brevipennis (Curtis, 1834); Halesus tesselatus (Rambur, 1842); Stenophylax sequax (McLachlan, 1875); Beraea pullata (Curtis, 1834); Beraeodes minutus (Linnaeus, 1761); Athripsodes commutatus (Rostock, 1874); Ceraclea fulva (Rambur, 1842); C. perplexa (McLachlan, 1877) and Mystazides longicornis (Linnaeus, 1758) are previously not listed for Finnmark. The total number of Trichoptera species known to occur in Finnmark is now 126 of which three belong in Rhyacophilidae, three in Glossosomatidae, 10 in Hydroptilidae, two in Philopotamidae, two in Psychomyiidae, nine in Polycentropodidae, five in Hydropsychidae, one in Arctopsychidae, nine in Phryganeidae, three in Brachycentridae, one in Lepidostomatidae, 57 in Limnephilidae, one in Goeridae, two in Beraeidae, one in Sericostomatidae, three in Molannidae and 14 in Leptoceridae. Four of the species, Oxyethira falcata, Asynarchus thedenii, Limnephilus diphyes and Ceraclea perplexa are listed in the 2010 Norwegian Red List for Species.
... Cyrnus crenaticornis (Kolenati, 1859) is recorded for the first time in South Norway. The species has previously been taken in S0r Varanger in eastern Finnmark (see Andersen & Wiberg-Larsen 1987). In Sweden it is re corded from a few provinces north to Da larna and Giistrikland (Forsslund & Tjeder 1942, Gullefors 1988). ...
... Lype reducta (Hagen, 1868) is not previously recorded from Norway. The species has a palaearctic distribution; taken in most parts of Europe including Denmark, Sweden and Finland (Botosaneanu & Malicky 1978, Andersen & Wiberg-Larsen 1987. In Sweden it is restricted to the southern regions: Skine, Halland, Smiland, Oland and Vastergotland (Forsslund & Tjeder 1942, Forsslund 1953). ...

Records of a total of 11 1 Trichoptera species from Buskerud are given, 92 species are taken in eastern Buskerud, and 70 in western Buskerud. The total number of species until now recorded from eastern Buskerud is 102, while the number from western Buskerud is 80. One species, Lype reducta (Hagen, 1868) is previously not recorded from Norway. Further, eight of the species are considered as rare in Norway. Four of these, Rhyacophila fasciata Hagen, 1859, Ironoquia dubia (Stephens, 1837), Limnephilus fuscinervis (Zetterstedt, 1840) and Athripsodes albifrons (Linnaeus, 1758) were taken only in eastern Buskerud, one species, Ceratopsyche silfvenii (Ulmer, 1906) only in western Buskerud, while three species, Hydroptila simulans Mosely, 1920, Hydropsyche contubernalis McLachlan, 1865 and Ylodes simulans (Tjeder, 1929) were taken in both regions.

The microcaddisfly (Trichoptera: Hydroptilidae) fauna is catalogued from a review of more than 1,300 literature citations through the end of 2020 to include 2,665 currently recognized, valid species in six subfamilies and 76 genera. Fourteen subspecies are included in the total as well as 23 fossil species and three fossil genera. The family Ptilocolepidae (Trichoptera), also covered in this catalogue, comprises 19 valid species in two genera; two subspecies and two fossil species are included in the total. The monotypic genus Eutonella , currently considered incertae sedis within Trichoptera, was formerly placed in Hydroptilidae and is also included in this catalogue. Genus-group and species-group synonyms are listed. Information on the type locality, type depository, sex of type, distribution by country, and other relevant taxonomic or biological information is included for each nominal species. Summary information on taxonomy, phylogeny, distribution, immature stages, and biology are provided for each subfamily, tribe, and genus where known. An index to all nominal taxa is provided to facilitate catalog use.

This chapter focuses on the island biogeography of aquatic invertebrates in the North Atlantic islands: Greenland, Svalbard, Iceland, Faroe Islands, Shetland and Orkney and adjacent larger regions, Norway and Britain. The North Atlantic area was also the scene for major tectonic developments from the Tertiary onwards. Aquatic insect groups, such as Ephemeroptera and Plecoptera are non-existent on Svalbard and the Faroes and only a single ephmemeropteran taxon is found in Greenland. The specimens in North West Iceland are related to Scandinavian specimens, but specimens in South West and South Iceland are related to Greenland specimens. The only endemic species of aquatic invertebrates in Iceland are two subterranean amphipods. These include: Crymostygius thingvallensis, and Cranonyx islandicus. Comparison with the Greenland fauna is difficult because of its Nearctic origins, but the other North Atlantic islands are dominated by Palaearctic species.

The Trichoptera include more species than any of the other primarily aquatic orders of insects, which are usually found in clean fresh water. Distribution of the species of an order based on geography can provide guidance for researchers working in the field. In the current study, for the first time, a list of known Trichoptera species in Kyrgyzstan is given along with a new record. The list is prepared based on the relevant literature between 1875 and 2020 and a study conducted in 2012. Literature search revealed that 21 known species of caddisflies of 13 genera and 8 families have been reported from Kyrgyzstan; our research found that Triaenodes reuteri McLachlan 1880 is also present in Kyrgyzstan. We also re-illustrate the male genitalia of T. reuteri and provide a detailed redescription. Based on literature search and our observations, the Kyrgyzstan caddisfly fauna has been poorly studied; it is expected that new records and new species will be found in Kyrgyzstan through further research.

This paper focuses on the origin of Trichoptera species in Iceland in light of the island biogeography of caddisflies in the North-Atlantic islands, i.e., Greenland, Svalbard, Iceland, Faroe Islands, Shetland, and Orkney, and adjacent larger regions, Norway and Britain. Three of the 12 recorded species have circumpolar distribution, the other nine are Palaearctic. The number of species declines with the distance from the mainland of Europe and is independent of the island sizes. However, the occurrence of species is stochastic, with only a few species common to the more remote islands—e.g., Iceland has 12 species and the Faroe Islands 20, but only 4 species are common to both islands. Studies on phylogeographic patterns of two species, Potamophylax cingulatus and Apatania zonella, show different history based on genetic markers. Potamophylax cingulatus in Iceland is from a western European lineage, distinct from two eastern and southern European lineages that may have diverged in southern refugia during the glacial periods of the latest Ice Age. The ancestors of the Icelandic population have migrated from the Iberian Peninsula up the west cost of Europe to the Faroe Islands and Iceland. The parthenogenetic A. zonella in Iceland originated near the Bering Strait, and has migrated along two routes, one westward through northern Eurasia and the other eastward through North America and Greenland to Iceland, where the two populations meet. Preliminary phylogeographic studies on two other circumpolar species, Limnephilus fenestratus and L. picturatus indicate possible interchanges between North America and Europe, but due to a low number of samples, it is difficult to state where the Icelandic population came from.

The controversy featuring Hydropsyche instabilis (CURT.) and H. siltalai DÖHL. is outlined. The lectotype of H. instabilis, a female in the CURTIS Collection, has been re-examined and is considered to be distinct from H. siltalai. The male imago depicted by McLACHLAN as H. instabilis has been found in the British Museum (Natural History). Contrary to the view of DÖHLER, based on McLACHLAN’s drawing and subsequently accepted in the literature, this specimen is considered to be conspecific with MOSELY’s instabilis i.e. with H. siltalai and not with the female lectotype of H. instabilis. However the lectotype in the CURTIS collection has priority for the name H. instabilis. SVENSSON & TJEDER’s claim that the designation by BOTOSANEANU & MARINKOVIC-GOSPODNETIĆ of a lectotype of H. siltalai DÖHL in the CURTIS Collection is invalid is upheld, but it is not agreed that their Swedish H. siltalai is conspecific with the female lectotype of H. instabilis or that TOBIAS had mixed the sexes of the two species. H. instabilis and H. siltalai should stand as discrete species. If the suggestion meets with approval, it is proposed to designate as lectotype of H. siltalai DÖHLER a male imago in the British Museum (Nat.

Based on independent studies of immature stages and adults of Athripsodes, sens. lat. (Leptocerus auctt. nee Leach, 1815), two distinct genera are recognized, Athripsodes Billberg, 1820, and Ceraclea Stephens, 1829, which together comprise a new tribe. Characters are given to distinguish the two genera in the larval, pupal and adult stages. Data are presented which support monophyletic hypotheses for the tribe and for each of the two genera.

The Hydropsyche morosa group is recognized as Hydropsyche subgenus Ceratopsyche. Through study of type specimens and of series collected over much of the range, geographic variation is assessed in Hydropsyche (C.) alhedra Ross and Hydropsyche (C.) cockerelli Banks. Hydropsyche (C.) racona Denning and H. (C.) riola Denning are designated as junior subjective synonyms of H. (C.) alhedra; and H. (C.) bicornuta Denning and H. (C.) jewetti Denning as junior subjective synonyms of H. (C.) cockerelli. Revised diagnoses are given for the two species. Diagnosis and description are provided for the male and female of Hydropsyche (C.) aenigma n. sp. from New York State; this species is contrasted with its close relatives H. (C.) alternans (Walker) and H. (C.) centra Ross.
