D e s c r i p t i o n: This species is extremely similar to
G. nifica
, so that a detailed description would be redundant. Instead, only the primary and secondary sexual characters are described:
(large): pronotum weakly oblong, up to 1.1 times as long as wide (
Fig. 30
); elytra with similar modifications as in
G. nifica
, but the carinae in posterior angles broader, of more irregular shape, and covered with more or less coarse granules (
Figs 30-31
); process of
1188
tergite
VII
of similar shape as in
G. nifica
, but slightly less erect (
Fig. 32
); aedeagus similar to that of
G. nifica
(
Fig. 33
).
: spermatheca as in
Fig. 34. E t y m o l o g y
: The name (Lat.: of the black mountain) refers to the Turkish name of the mountain range, where the species was discovered.
Figs 30-34
:
Geostiba atromontis
sp.n.
30-33: holotype): (
30
) forebody; (
31
) elytra in lateral view; (
32
) process of tergite VII in lateral view; (
33
) median lobe of aedeagus in lateral view; (
34
) spermatheca. Scale bars: 30: 0.5 mm; 31-32: 0.2 mm; 33-34: 0.1 mm.
I n t r a s p e c i f i c v a r i a t i o n: The male secondary sexual characters are subject to considerable intraspecific variation; they are fully developed only in four of the
seven male
type
specimens.
C o m p a r a t i v e n o t e s: As indicated above,
G. atromontis
is extremely similar to
G. nifica
; both species can be distinguished only based on the modifications of the elytra and tergite
VII
of large males with pronounced secondary sexual characters. Although these differences are slight, they are interpreted as evidence of interspecific rather than intraspecific variation, not only because they seem to be constant, but also because the ranges of both populations are separated by a considerable stretch of low-altitude plain. Using the key in
ASSING (2005a)
, both
G. nifica
and
G. atromontis
would key out at couplet 77 (see supplementary key in section on
G. renneri
sp.n.
).
