New griff enfl y, Bohemiatupus elegans from the Late
Carboniferous of western Bohemia in the Czech Republic
(Odonatoptera: Meganisoptera: Meganeuridae)
Abstract. A new griffenfl y, Bohemiatupus elegans n. gen., n. sp. (Meganeuridae) is described
from the Upper Carboniferous ( Bolsovian) deposits of the Ovčín near Radnice in western Bohemia
(Czech Republic). The new taxon based on fore- and hindwing venation is compared with the other
meganeurid genera. It is the fi rst record of a large griffenfl y from the continental basins of the Bohemian
Massif supplementing the other giant insects such as Bojophlebia prokopi Kukalová-Peck 1985 or
Carbotriplura kukalovae Kluge 1996 from the same strata.
Résumé. Une nouvelle « libellule géante », Bohemiatupus elegans du Carbonifère supérieur de
la Bohème de l’ouest (République Tchèque) (Odonatoptera: Meganisoptera : Meganeuridae) .
Un nouveau genre et une nouvelle espèce de Meganeuridae (Meganisoptera), Bohemiatupus elegans
n. gen., n. sp. est décrit du Carbonifère supérieur d’Ovčín près de Radnice (ouest de la Bohême,
République Tchèque). Ce nouveau taxon est basé sur la nervation des ailes antérieures et postérieures.
Il est comparé aux autres Meganisoptera décrits. Il s’agit de la première « libellule géante » des bassin
continentaux du massif de Bohème, mais pas du premier insecte géant des mêmes aire et étage
(Bojophlebia prokopi Kukalová-Peck 1985, Carbotriplura kukalovae Kluge 1996).

Paleozoic odonatopteran order Meganisoptera
Martynov 1932 (so-called ‘Protodonata’) represents
the ‘stem group’ to true Odonata. However, the
members of Meganisoptera diff er from Odonata by
absence of nodus and pterostigma in wing venation,
as well as males lacking secondary genitalia (Bechly et
al. 2001). Above all, this group is well known for the
insects with largest wingspan that have ever lived such
as Meganeuropsis permiana Carpenter 1939 from Early
Permian of Kansas that reached wingspan more than
700 mm (Carpenter 1939, 1947).
e clade Odonatoptera is fi rst recorded about
320 million years ago in the Namurian, and its main
subgroups Odonatoclada Bechly, 2003 (= the clade
that comprises the Lapeyriidae Nel et al. 1999, the
Campylopteridae Tillyard 1928 and the Nodialata
Bechly 1996 viz. the Odonatoptera with a true nodus),
Meganisoptera, and Geroptera Brodsky 1994 suddenly
appeared in Westphalian (Brauckmann & Zessin 1989;
Riek & Kukalová-Peck 1984; Jarzembowski and Nel
2002). Meganisoptera are not very frequent in the fossil
record of Namurian and Westphalian deposits, viz.
the Westphalian Carpentertypus durhami (Carpenter
1960), Piesbergtupus hielscheri Zessin 2006, Arctotypus
diluculum (Whalley 1980), Palaeotherates pennsylvanicus
Handlirsch 1906, and Gallotupus oudardi Nel et al.
2008; and the Namurian Sinomeganeura huangheensis
Prokop et al. 2008, Shenzhousia qilianshanensis Zhang
et al. 2006, and Namurotypus sippeli Brauckmann &
Zessin 1989 (Zessin 2006; Zhang et al. 2006; Ren et
al. 2008; Nel et al. 2008, 2009).
e continental basins of the Bohemian Massif are
represented by a number of insect localities ranging
in age from the Duckmantian (Westphalian B) to
the Middle Stephanian. In the central and western
Bohemia the most famous localities are in the Radnice
Member of Bolsovian age (Wesphalian B-C), which
involves localities like Lubná, Příčina, Štílec, Vrapice
and Otvovice or in the Nýřany Member of the Asturian
age where Nýřany and Třemošná belong among the
most famous ones. Predominance of the Blattodea is
signifi cant in Nýřany and Lubná (Kušta 1883; Fritsch
1901; Handlirsch 1920; Kukalová 1955), while others
are represented by single records of palaeopterous
insects (Ephemeroptera, Paleodictyoptera), (Fritsch
1880; Kukalová 1958; Kukalová-Peck 1985; Novák
1880).

J. P & A. N
New insect material was recently discovered at
Ovčín near Radnice during extensive excavations by
palaeobotanists in tuff layers so called „whetstone
horizon“ from the roof of the Lower Radnice Seam
(Lower Bolsovian) with well known buried plants
preserved in situ (see Opluštil et al. 2007, 2009;
Libertín et al. 2009). Insect fauna is very rare with two
other undescribed specimens of palaeodictyopterid
larvae and orthopteroid insect (Prokop unpubl.).
Material and methods
e fossil specimen was observed under stereomicroscopes Zeiss
Cytoplast in dry state and under ethyl alcohol. Due to large
dimensions of the specimen the venation pattern line drawing
was redrawn from color photograph and revised by parallel
observation under stereomicroscope. Drawing was fi nally
readjusted to the photograph scale using of graphic software
(Adobe Photoshop). Photographs were made in dry state and
under ethyl alcohol by digital camera Nikon D80 with macro
lens Nikon AF-S VR Micro-Nikkor 105 mm in the highest
contrast as possible by single sided cross-light pre-exposure.
Type material was collected in 2006 during extensive excavations
by group of palaeobotanists so called “Czech mafi a” in Ovčin
near Radnice and housed in the collection of West Bohemian
Museum in Plzeň, Czech Republic.
We use the wing venation nomenclature of Nel et al. (1993),
and Bechly (1996). Systematic and divisions follows the concept
of higher phylogenetic classifi cation of Odonatoptera proposed
by Bechly (1996, 2007).
e venational symbols used here specifi ed as follows: symbols
in capitals denote the longitudinal veins (CA / CP – costal
anterior / posterior, ScA / ScP – subcostal anterior / posterior,
RA / RP – radial anterior / posterior, IR – intercalary radial
posterior, MA / MP – medial anterior / posterior, CuA / CuP
– cubital anterior / posterior, AA – anal anterior).

Radnice Basin, Czech Republic
Type strata. Upper Carboniferous, Westphalian B-C,
Bolsovian, Kladno Formation, Radnice Member, Low-
er Radnice Coal, Whetstone Horizon.
Description. Negative imprint of a fore and a
hindwing in life position, probably hyaline. Forewing
broadest part at about midwing; length of fragment
to fi rst distortion break about 115 mm, probable total
length about 260 mm; wing width 49 mm; estimate
ratio (wing length/width) about 5.3; precostal area of
CA and CP not preserved, but ScA is certainly short
as it is absent above arculus level; simple concave ScP
nearly parallel to anterior wing margin, and reaching it
in apical part of wing, at least distal of 190 mm from
wing base, but extreme apex of ScP not preserved; nine
visible ‘antenodal’ cross-veins in area between ScP and
C, more or less aligned with cross-veins in area between
ScP and RA; the most basal cross-vein perpendicular to
C, ScP, and RA, stronger than others ‘antenodals’, and
making a distinct brace corresponding to the primary
antenodal cross-vein Ax0 not preserved; ‘subnodus’
between RA and RP near base of RP2; stem of radial
veins dividing 34 mm from wing base forming ‘arculus’,
RA strong, simple, parallel to ScP, and ending probably
in wing apex; R and MA fused in their basal parts; RP
bifurcating into RP1/2 and RP3/4 88 mm from wing
base; only basal part of RP3/4 preserved, simple; IR2
and other distal branches of RP partly preserved on
isolated apical part; MA nearly straight with its most
basal posterior branches partly preserved, fi rst opposite
bifurcation between RP1/2 and RP3/4; only fragments
of MP vein preserved and visible at level of arculus,
its medial part being hidden under rock, but MP
probably simple; at least CuA forming strongly oblique
cross-vein but remains of an oblique cross-vein CuP
also visible in area between MP and AA, CuP 15 mm
from wing base, CuA one cell distally; CuP separating
from CuA 36 mm from wing base and six cells distal of
CuP-crossing; distal part of CuA with numerous main
posterior branches; CuP very long and rather straight,
with four main simple posterior branches covering a
relatively small area, basal part before its fi rst furcation
long and straight, about 4 mm long, width of area of
CuP along posterior wing margin 51 mm; distal part
of AA forming a relatively large are, width of this are
along posterior wing margin 49 mm; basal part of AA
(+ Cu) forming a very weak curve; anal and cubito-
anal areas rather broad, 17 mm wide, with numerous
posterior branches.
e preserved parts of the hindwing are very
similar to the forewing in pattern of venation except
for the cubito-anal area, hindwing slightly broader
than forewing; length of wing fragment about 85 mm,
probable total length as about fore wing; wing width
50 mm; estimated ratio (wing length/width) 5.2; anal
and cubito-anal areas distinctly broader than in the
fore wing, 30 mm wide; preserved basal part of CuP
long and nearly straight but distal part not preserved;
distal part of AA forming a relatively large area with
8–9 main posterior branches.
Discussion
is Odonatoptera is clearly related to the
Meganisoptera that comprises the ‘families’
Namurotypidae Bechly 1996, Meganeuridae
Handlirsch 1906, Kohlwaldiidae Guthörl 1962, and
Paralogidae Handlirsch 1906. Relationships with the
Namurotypidae are excluded because Bohemiatupus
n. gen. has a distally branched CuP, instead of being
simple. e Paralogidae have a long and straight CuP as
in Bohemiatupus n. gen., but with numerous branches
covering a broader area than CuA and distal branch
of AA. e Kohlwaldiidae are characterized by having
the distal parts of CuP and AA strongly reduced,
which is not the case of Bohemiatupus n. gen. (Nel et
al. 2009). e Meganeuridae are characterized by the
presence of a typical ‘subnodal’ oblique vein between
RA and RP near the base of RP2, which is preserved
in our fossil. e very large size of Bohemiatupus n.
gen. supports affi nities with this family even if several
Meganeuridae have distinctly smaller dimensions
(Nel et al. 2009). Bohemiatupus n. gen. cannot be
attributed to the Meganeurinae because its vein ScA is
short. e Carpentertypinae Zessin 1983 [type genus
Carpentertypus Zessin 1983, based on one species
C. durhami (Carpenter 1961)] is based on a very
fragmentary fossil, with no information on any of the
basal halves of the wings. Nevertheless it diff ers from
Bohemiatupus n. gen. in its distinctly less numerous cells
and narrower area covered by MA. e Piesbergtupinae
Zessin 2006 (type genus Piesbergtupus Zessin 2006) is
characterized by the narrow anal area of fore wing and
presence of one oblique cross-vein distal of the oblique
braces CuP and CuA and basal of the distal branch of
CuP re-emerging from CuA+CuP, plus the long CuP
and AA1 (Zessin 2006, 2008; Nel et al. 2009). e
pattern of wing venation of Bohemiatupus n. gen. fi ts
very well with the Tupinae. e monophyly of this last
group is not very clearly established (Bechly 1996; Nel
et al. 2009), but we can now restrict the comparison of
Bohemiatupus n. gen. to the genera that are currently
attributed to it. After the key to the tupine genera of
Nel et al. (2009), Bohemiatupus n. gen. would fall
New Late Carboniferous griff enfl y in western Bohemia
187
near the Permian genus Tup us Sellards 1906 because
of the following characters: the two braces CuP and
CuA oblique, not fused into a long, oblique vein; AA1
with several posterior branches; and CuP with more
than three concave branches. Bohemiatupus n. gen.
greatly diff ers from Tupus in its hindwing cubito-anal
area distinctly broader than that of fore wing. Some
‘enigmatic’ genera are based on incomplete wings, i.e.
the Carboniferous genera Shenzhousia Zhang et al.
2006 and Boltonites Handlirsch 1919, and the Permian
Petrotypus Zalessky 1950. Petrotypus needs a complete
redescription, and it is based on a very poor fossil.
Nevertheless, its CuP seems to be simple and very
straight after Zalessky (1950), unlike Bohemiatupus n.
gen. Shenzhousia shares with Bohemiatupus n. gen. a
very long and straight CuP but with numerous posterior
branches covering a broad area, unlike Bohemiatupus
n. gen. (Zhang et al. 2006). After the fi gure of Bolton
(1922: fi g. 44), Boltonites has a distinctly curved CuP,
shorter than that of Bohemiatupus.
Conclusions
Bohemiatupus n. gen. is established for Bohemiatupus
elegans n. sp. (type species) that exhibits unique
combination of characters within Meganeuridae. e
present discovery represent the fi rst record of large
griff enfl y from the continental basins of the Bohemian
Massif supplementing the other giant insects such
as Bojophlebia prokopi Kukalová-Peck 1985 or
Carbotriplura kukalovae Kluge 1996 from the same
strata.
Moreover, the material from Ovčín near Radnice
represents an extraordinary source of fossil plants in situ
and other animals like arachnid, fi sh and amphibian
trace fossils those enable study of developed peat
mire ecosystem into a shallow lake gradually fi lled by
redeposited volcanic ash from Bolsovian of western
Bohemia (Czech Republic).
