Additional material examined: 13: Appl 1878 I. Beirut ( NHMW).

D i a g n o s i s: 2.8-3.2 mm; habitus as in Fig. 227 View Figs 221-236 . 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 View Figs 221-236 ), only slightly shorter than postocular region in dorsal view. Antenna as in Fig. 230 View Figs 221-236 . 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 View Figs 221-236 ). 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 View Figs 221-236 ); palisade fringe at posterior margin of tergite VII more distinct.

3: sternite VIII as in Fig. 232 View Figs 221-236 ; median lobe of aedeagus as in O. hatayana apically bifid ( Fig. 234 View Figs 221-236 ), 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 View Figs 221-236 ); 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 View Figs 221-236 ); spermatheca of similar shape as in O. hatayana ( Fig. 236 View Figs 221-236 ).

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.
