D i a g n o s i s:
2.8-3.2 mm
; habitus as in
Fig. 227
. Highly similar to the evidently very closely related
O. hatayana
ASSING
from central southern
Anatolia
(see descriptions in
ASSING 2004b
, in press), but distinguished as follows:
Body larger and more distinctly bicoloured: head dark brown to blackish, distinctly darker than the reddish or reddish-yellow pronotum. Puncturation of forebody denser and more distinct (especially on head and pronotum). Eyes larger (
Fig. 229
), only slightly shorter than postocular region in dorsal view. Antenna as in
Fig. 230
. Pronotum relatively larger, 1.35-1.45 times as wide as head. Elytra relatively longer, at suture 0.80-0.90 times as long as pronotum (
Fig. 228
). Metatarsomere I longer, as long as or even longer than the combined length of metatarsomeres II-IV. Abdomen with much denser and more distinct puncturation (
Fig. 231
); palisade fringe at posterior margin of tergite VII more distinct.
3: sternite VIII as in
Fig. 232
; median lobe of aedeagus as in
O. hatayana
apically bifid (
Fig. 234
), but with relatively shorter and more strongly bent ventral process (lateral view), with less pronounced crista apicalis, and with internal structures of slightly different shape (
Fig. 233
); apical lobe of paramere as in
O. hatayana
.
♀
: sternite VIII of similar shape as in
O. hatayana
, its posterior margin almost truncate, with distinctly modified stout marginal setae (
Fig. 235
); spermatheca of similar shape as in
O. hatayana
(
Fig. 236
).
C o m m e n t s: The original description of
O. cingulum
is based on
two syntypes
from "
Syrien
... ohne nähere Fundortsangabe" and from "Beirut" (
BERNHAUER 1902
).
The
former is a female and deposited in the
Berrnhauer
collection at the
FMNH
.
The
latter was found in the collections of the
NHMW
; it is a male and here designated as the
lectotype
.
C o m p a r a t i v e n o t e s: Among other Eastern Mediterranean congeners of intermediate size, the species is characterised especially by its coloration, its relatively long, apically weakly incrassate, pale reddish antennae (similar to that of
Derocala
species
), the dense puncturation, the rather short elytra, the reduced hind wings, the dense puncturation of the abdomen, and by the morphology of the genitalia.
Oxypoda cingulum
belongs to the
O. brachyptera
group, as can be inferred from the shape and chaetotaxy of the apical lobe of the paramere and from the morphology of the median lobe of the aedeagus, especially the apically bifid ventral process. From most species of this group,
O. cingulum
is separated by larger size alone.
D i s t r i b u t i o n: The species is known only from the surroundings of
Beyrouth
,
Lebanon
. Recent records have, to my knowledge, not become known.
