Additional material examined: 1♀, Ukraine, Krim ( FMNH).

C o m m e n t s: The original description of this species is based on syntypes from the Krim peninsula, Ukraine (one male and two females), and from the Parnass range in Greece (one female). The type specimens from both localities are not conspecific, so that a lectotype designation is mandatory and the male from the Krim peninsula is here designated as the lectotype. The female from the Parnass belongs to an unidentified – possibly undescribed – species ; its general appearance is similar to that of O. brachyptera , but the spermathecal duct is shorter and of different shape.

The similar morphology of the median lobe of the aedeagus, the shape and chaetotaxy of the apical lobe of the paramere, as well as the morphology of the spermatheca suggest that O. longicollis is not affiliated with species of the O. brachyptera group, but rather closely related to O. praecisa .

R e d e s c r i p t i o n: Small species, 2.3-2.7 mm; habitus of forebody as in Fig. 108 . Coloration: Reddish brown, with abdominal segment VI and the anterior half of segment VII somewhat infuscate; legs testaceous; antennae pale reddish.

Head as wide as long or weakly transverse, relatively large in relation to pronotum ( Fig. 108 ); puncturation fine and indistinct; microsculpture shallow, but distinct; eyes relatively small ( Fig. 110 ), little more than half the length of postocular region in dorsal view. Antennae as in Fig. 109 . Penultimate joint of maxillary palpus of moderate length, about 2.5-3.0 times as long as wide

Pronotum 1.20-1.25 times as wide as long and only 1.15-1.20 times as wide as head; maximal width in anterior half; puncturation shallow and dense, somewhat ill-defined, but more distinct than that of head; microsculpture shallow ( Fig. 108 ).

Elytra slightly wider than pronotum and at suture about 0.75 times as long as pronotum; puncturation dense and distinct, much more so than that of head and pronotum ( Fig. 108 ). Hind wings reduced. Metatarsomere I slightly longer than the combined length of II-III.

Abdomen about as wide as elytra; puncturation on anterior tergites dense and distinct, gradually decreasing in density towards apex of abdomen; microsculpture absent or indistinct; posterior margin of tergite VII without palisade fringe.

3: posterior margin of sternite VIII strongly convex, but not angled in the middle ( Fig. 112 ); aedeagus with apically unincised and, in lateral view, somewhat angled ventral process ( Figs 113-114 ); apical lobe of paramere as in Fig. 111 .

♀: posterior margin of sternite VIII weakly concave in the middle ( Fig. 115 ); spermatheca with rather short duct ( Fig. 116 ).

D i s t r i b u t i o n: The species is known only from the Krim peninsula, Ukraine.
