Comment
: Based on an unspecified number of
syntypes
from “Anatolien: Goek-Dagh und Alem-Dagh”,
C. bodemeyeri
was originally described as a distinct species (
REITTER 1903
). It was subsequently attributed to
C. perispinctum
KOLENATI, 1846
as a subspecies (
VÍT & BESUCHET 2004
).
While the distribution of
C. bodemeyeri
is confined to Northwest
Turkey
,
C. perispinctum
is widespread and not uncommon in
Georgia
and has also been recorded from
Azerbaijan
. The previous record from
Armenia
(
VÍT & BESUCHET 2004
) is most likely based on Besuchet (unpublished notes), who erroneously attributed specimens labelled “Armen. Geb.” to
Armenia
rather than to
Georgia
(see
ASSING & SCHÜLKE 2019
). In any case, the distributions of both taxa are separated by a distance of nearly
800 km
, thus casting doubt on the previous subspecific concept. A comparison of the aedeagi of
C. bodemeyeri
and
C. perispinctum
eventually revealed that they are similar, but not identical, and distinguished particularly by the shape of the apex of the median lobe in ventral view (
C. bodemeyeri
: ventral process more strongly constricted subapically and apico-laterally not distinctly angled). For comparison see the aedeagus of
C. perispinctum
in
Figs 25–26. A
third argument comes from the discovery of a third similar species of the same species group, which was recently collected in Southeast
Bulgaria
and which is described (as
C. liguliferum
) in an appendix at the end of this paper.
In consequence, the above observations suggest that these taxa represent distinct, albeit closely related species rather than subspecies.
Diagnosis
: Body length
1.2–1.4 mm
; length of pronotum
0.39–0.45 mm
; width of pronotum
0.50–0.57 mm
; length of antennae approximately
0.6 mm
. Habitus as in
Fig. 1
. Colouration: body reddish to dark-brown with the elytra often somewhat darker than head and pronotum.
Eyes composed of approximately ten ommatidia. Antenna with pronounced club formed by antennomeres IX–XI; antennomere VIII slightly smaller than antennomere VII and much smaller than antennomere IX; antennomere XII nearly twice as long as broad.
Pronotum 1.20–1.25 times as broad as long, broadest in anterior half, and strongly convex in cross-section; lateral margins straight or indistinctly sinuate in posterior half.
Elytra each anteriorly with a transverse impression with long and tomentose whitish pubescence; humeral carina nearly obsolete.
: protibia subapically distinctly curved and somewhat flattened and excavate on inner side; aedeagus (
Figs 29–31
)
0.50–0.55 mm
long; ventral process apically extending into a long and narrow median process in ventral view; internal sac with a pair of moderately sclerotized oblong structures; paramere bisinuate, far from reaching apex of ventral process, and apically with a long curved seta.
Distribution and natural history
: The known distribution of
C. bodemeyeri
is confined to Northwest
Turkey
from
Istanbul province
in the west to
Karabük
in the east (
Map 1
). The altitudes range from
130 to 1720 m
, from the beech forest to the fir forest zone. Some specimens collected at the end of April and in the beginning of May are teneral.
