Introduction
The caddisfly fauna of Sakhalin Island has
been previously studied. Vshivkova and Kholin
(1997) listed 117 taxa of caddisflies from the
Island. Later, Hydroptila itoi Kobayashi, 1977,
was reported from Tunaicha Lake located in
South Sakhalin as a new species record for Russ-
ian fauna (Arefina 2002). Most recently, a new
species of Polycentropodidae from the genus
Plectrocnemia Stephens, P. levanidovae, was col-
lected from Naiba River (Arefina et al. 2003).
During expeditions to Sakhalin Island in 2001
and 2002, sponsored by the International Pro-
grams Division of the U.S. National Science
Foundation and the Institute of Biology and Soil
Sciences of Russian Academy of Sciences, Vladi-
vostok, new collections of caddisflies were made,
which included taxa new to science and new dis-
tribution records. This work includes the results
of these research expeditions, with the exception
of representatives from the family Hydroptilidae,
reported in a different work (Arefina and
Armitage in press).
Males and females of Kisaura minakawai
new species (Philopotamidae) and Oecetis tes-
tacea sakhalinica new subspecies (Leptoceridae)
from Sakhalin Island are described and illustrated
in the present work. Glossosoma neffi Arefina,
2000, Cyrnus fennicus Klingstedt, 1937, Plec-
trocnemia wui Ulmer, 1932, Psychomyia minima
(Martynov, 1910), Agrypnia czerskyi (Martynov,
1924), Micrasema gelidum MacLachlan, 1876,
M. hanasensis Tsuda, 1942, Ceraclea annulicor-
nis (Stephens, 1836) and Oecetis nigropunctata
Ulmer, 1908 represent new records for Sakhalin
Island. Kisaura borealis Kuhara, 1999 and Plec-
trocnemia nagayamai Schmid, 1964 are newly
recorded for the Russian fauna. Thus, the present
list of caddisflies known for Sakhalin Island
includes 138 species, including those six taxa
reported in the hydroptilid paper.
Type material is preserved in alcohol and
deposited in the collection of the Institute of Biol-
ogy and Soil Science, Far Eastern Branch of the
Russian Academy of Sciences, Vladivostok, Rus-
sia.

Abstract: Currently, 119 taxa of caddisflies are recorded from Sakhalin Island. A recently submitted
manuscript (Arefina and Armitage in press) reports two new species and four new records from the family
Hydroptilidae for this Far Eastern District. Examination of material collected during expeditions to the Island
in 2001 and 2002 has revealed one new species, one new subspecies, and 11 new records of caddisflies from
seven families. Newly described taxa include Kisaura minakawai (Philopotamidae) Oecetis testacea
sakhalinica (Leptoceridae). Glossosoma neffi Arefina, 2000, Cyrnus fennicus Klingstedt, 1937, Plectrocne-
mia wui Ulmer, 1932, Psychomyia minima (Martynov, 1910), Agrypnia czerskyi (Martynov, 1924), Micrase-
ma gelidum MacLachlan, 1876, M. hanasensis Tsuda, 1942, Ceraclea annulicornis (Stephens, 1836) and
Oecetis nigropunctata Ulmer, 1908 are recorded from Sakhalin Island for the first time. Kisaura borealis
Kuhara, 1999 and Plectrocnemia nagayamai Schmid, 1964 are new records for the Russian fauna. Male and
female of Ceraclea complicata (Kobayashi, 1984) previously known from Sakhalin Island are redescribed
and illustrated.

(male).
Material examined: Five males, Sakhalin,
Vicinity of Yuzhno-Sakhalinsk Town, Rogatka
River, 7.viii.2001 (T. Tiunova).

(Hokkaido, Honshu).
Remarks: This species is recorded for the
Russian fauna for the first time.
Kisaura minakawai Arefina, new species
(Figs. 1, 2).
Type material: Holotype male: South
Sakhalin, a tributary of Belaya River near Biolog-
ical Station "Sokol", 9.viii.2002 (N. Minakawa).
Paratypes: Two males, two females, same data as
holotype; one male, South Sakhalin, Lyutoga
River at Vysokoye Village, at light, 25-
26.vii.2001 (E. Makarchenko).
Description: Length of forewing: male - 6.0-
7.2 mm, female - 8.2-8.4 mm. Vertex of head and
thorax dark brown. Antennae dark brown with
light annulation. Maxillary palpi brown, with
apical portion of fourth article light; labial palpi
pale. Legs yellowish brown, spurs brown. Wings
light brown to brown, with light vague spots
spread over marginal areas.
Male Genitalia: Segment IX longer than
basal segment of inferior appendage; medial por-
tion of anterolateral margin expanded anteriorly
in view of triangular projection; anteroventral
margin with deep triangular excision in ventral
view; posterolateral margin oblique with shallow
excision; posteroventral margin slightly concave
mesally in ventral view. Tergum X long, taper-
ing to deeply divided apex in dorsal view, mem-
branous but slightly sclerotized laterally and over
mesal notch, mesal sclerotization visible in lateral
view. Preanal appendages elongate, curved later-
ad in dorsal view. A pair of spiniform processes,
arising from base of tergum X, very long, curved
ventrad in lateral view, protruding beyond tergum
X and base of terminal segment of inferior
appendage, with long black apices. Basal seg-
ment of inferior appendages nearly ovate, its dor-
sal margin straight. Terminal segment of inferior
appendage longer than basal segment by one-
third of its length, nearly uniform in width, but
somewhat wider at subapical portion, with round-
ed apex. Comb of black sclerotized teeth present
on inner surface of terminal segment, parallel to
dorsal margin of segment, slightly curved inward
in ventral view. Phallus with small sclerites.
Female Genitalia: Sternum VII with small
rounded mesoventral projection. Segment VIII
annular, dorsally longer than ventrally, its pos-
terolateral margin with rounded projection sub-
dorsally bearing two setae. Segment X small,
slightly sclerotized dorsally. Segment XI with
very short cerci.
Diagnosis: Twenty-eight species of the
genus Kisaura are presently known in Eastern
Asia. Among those species Kisaura minakawai
resembles K. lanceolata Sun, 1997, K. venusta
Malicky and Chantaramongkol, 1993, K. sura
Malicky and Chantaramongkol, 1993 and K.
surasa Malicky and Chantaramongkol, 1993 in
having spiniform processes protruding slightly
beyond basal segment of inferior appendages.
The new species differs from the species men-
tioned above by terminal segment of the inferior
appendages much longer than basal segment, by
tergum X shorter than spiniform processes, and
by the presence of a deep notch divided the ter-
gum X apically and also by asymmetry of geni-
talia.
Etymology: This species is named after Dr
Noboru Minakawa (Saga Medical School, Saga,
Japan).
Distribution: The species is known only
from South Sakhalin.
Remarks: The anterior portions of segment
IX slightly asymmetrical in both the holotype and
paratype males. This causes the spiniform
processes of tergum X to be unequal in length,
with the right process longer than left one.

New findings of caddisflies (Insecta: Trichoptera) from Sakhalin Island
with blunt apex, left paramere spine absent.
Female genitalia: Superior appendages
rather short, fused mesally. Gonopod plates
closely approximate on midline, each with trian-
gular apical projection separated apically by deep
sinuous excision in ventral view. Supporting
bands of spermathecal sclerite situated internally
on apical projections of gonopod plates, extend-
ing anteriorly to anterior margin of segment VIII.
Diagnosis: Ceraclea complicata belongs to
the Ceraclea (Athripsodina) annulicornis Group.
Within the group this species belongs to the sub-
group including C. annulicornis (Stephens,
1836), C. globosa Yang and Morse, 1988, C.
ruthae (Flint, 1965), C. shuotsuensis (Tsuda,
1942) and C. armata Kumanski, 1991. All enu-
merated species have a very large base of the
phallus. The male of C. complicata can be easily
recognized among species in the C. (A.)
annulicornis Group by the presence of a long and
straight median process of the inferior
appendages directed caudad. The female of the

Type Material: Holotype male: South
Sakhalin, north shore of Vavaiskoye Lake, near
the mouth of Shlyuzovka River, 18.viii.2002 (N.
Minakawa). Paratypes: Three males, two
females, same data as holotype; one female, same
locality and date (V. Teslenko).
Description: Forewing length: male - 7.1-8.0
mm, female - 7.0. Spurs formula: 0-2-2.
Male Genitalia: Dorsolateral lobes of seg-
ment IX forming small triangular project with
rounded apex. Preanal appendages long, clavate,
extending slightly beyond slender mesal process

ventral branch tapering and curved upwards in
lateral view, in ventral view its external margin
concave and internal margin convex, forming
slender apical portion; dorsal branch vertical,
with pointed apex and subapical acute, sinuous
project directed posteroventrad. Phallus symmet-
rical, with dorsal margin tapering to narrow apex

New findings of caddisflies (Insecta: Trichoptera) from Sakhalin Island
nearly quadrate in ventral view.
Immature Stages: Unknown.
Diagnosis: The male of the new subspecies
differs from those of Oecetis testacea testacea
Curtis, 1834 and O. testacea kumanskii Yang and
Morse, 2000 by the shape of the dorsal branch of
the inferior appendages. The female of the new
subspecies is most similar to the female of O. tes-
tacea kumanskii, but differs in the shape of seg-
ment IX in lateral view.
Distribution: This new subspecies is known
only from the type locality in South Sakhalin.
Etymology: This subspecies is named for the
island on which it was found.

... The NJ trees of length 658 were obtained, which is shown in Fig. 3. ML analyses showed twelve genetically distinct groups, which supports the species except for K. nozakii (Kuhara 1999). The unknown larvae were grouped clearly with the adult specimens of K. minakawai Arefina 2005, supported by a high bootstrap value (100), although they are paraphyletic with respect to the adults. The mean, uncorrected pair-wise genetic distance (p-distance) within the lineage of adult specimens of K. minakawai and Kisaura larval specimens was 2.3% (range, 1.9-2.6%). ...

Four genera of Philopotamidae (Trichoptera) are known from Japan: Chimara, Dolophilodes, Kisaura, and Wormaldia. Among them, adults of the genus Kisaura are known in the Oriental and East Palearctic region; but until now, larvae of this genus have not been observed. In this study, molecular evidence is presented to support the relationship between adults and larvae of Kisaura minakawai Arefina 2005 from hyporheic zones of Japanese rivers. Morphological features of the larva of K. minakawai, which include very small eyes and somewhat dorsoventrally flattened (depressed) head capsules, compared with those of other philopotamid species, are also suggested to be adapted to the hyporheic zone. Detailed morphology of K. minakawai larval characters are provided.

Previously, caddisflies of the genus Plectrocnemia Stephens, 1836 were unknown in the fauna of Siberia. In May-October 2018 adult P. kusnezovi Martynov, 1934 and P. wui (Ulmer, 1932) were collected in the upper part of the Yenisei River basin (Republic of Khakassia, Abakan city, Abakan River valley) with a UV lamp. These records clarify the northern and western boundaries of their ranges. Distribution of P. kusnezovi and P. wui in Asia and flight periods in the region are given. A possible record of P. conspersa (Curtis, 1834) in Western Siberia is discussed; this species is known from the Ural Mountains, Southern Siberia (Salair Ridge) and Xinjiang-Uygur Autonomous Region of China.

To date, only 24 species in nine genera of micro-caddisflies (Trichoptera: Hydroptilidae) have been recorded from the Russian Far East,with only three species known from SakhalinIsland. Specimens collected during expeditions to the continental Khabarovsk Territory in 1996 and2000 and on Sakhalin Island in 2000 and 2001 have increased this total. Two hydroptilid speciesnew to science: Hydroptila spinosa sp. n. and Oxyethira tiunovae sp. n. are herein described and illustrated. Oxyethira distinctella MACLACHLAN,1880 is recorded for the first time from the Russian Far East. Three species already known from the continental portion of the Russian Far East {Orthotrichia costalis (CURTIS) 1834; Stactobiella biramosa MARTYNOV 1929; and, Stactobia tshistjakovi AREFINA and MORSE 2002) represent new records for Sakhalin Island.

The results of biogeographic and ecofaunistic study of the Sakhalin Island Trichoptera fauna are given. There 117 caddisfly species belonging to 21 families and 57 genera are recorded from this island. Based on their faunistic and biogeographical composition Sakhalin Island divided into two large areas - north part with predominance of boreal species and south part, where palearchearctic elements are dominant. It is noted that ecological factor caused by differences in geomorphology of areas may exert influence on the faunistic composition.

A male and a female of a new species of the genus Glossosoma, belonging to the subgenus Synqfophora, are described and compared with the closely related G. (S.) altaicum (MARTYNOV). Until now, on the Russian Far East, the genus Glossosoma was represented by six species belonging to the subgenus Synafophora, G. (S.) nylanderi McLACHLAN., 1879, G. (S.) intermedium (KLAPALEK, 1892), G. (S.) altaicum (MARTYNOV, 1914), G. (S.) dulkejti (MARTYNOV, 1934), G. (S.) ussuricum (MARTYNOV, 1934) and G. (S.) angaricum (LEVANIDOVA, 1967). However, while engaged in the study of Far Eastern caddisflies, from the collection obtained by T. Tiunova from the Tumnin River in the Khabarovsk Territory, I discovered a new species of the genus Glossosoma belonging to the subgenus Synafophora as well. The specimens of this new species were collected at several places of the middle part of the Tumnin River for a distance of approximately 80 km (49.7 miles) during two rafting expeditions in June and July of 1997. Although the new species, G. (S.) neffi, is closely related to G. (S.) altaicum and both coexist at the Tumnin River, G. (S.) neffi remains local to the Tumnin River while G. (S.) altaicum is widely spread throughout the southern parts of Siberia and the Russian Far East, Korea, Mongolia and Japan. The two species differ in details of both male and female genitalia. Type material is preserved in alcohol and held in the collection of the Institute of Biology and Soil Sciences, Far Eastern Branch of the Russian Academy of Sciences, Vladivostok, Russia. The terminology used in describing the genitalic structures follows SCHMID (1980).
