D e s c r i p t i o n: 4.2-5.5 mm; habitus as in Fig. 181 . Similar to O. collaris ( Figs 181-184 ), but distinguished as follows:

Coloration as in O. collaris , but maxillary palpi on average darker, usually dark brown to blackish brown, and elytra on average more extensively infuscate near postero-lateral angles. Head of similar morphology as in O. collaris , but eyes usually slightly larger ( Fig. 183 ), about as long as postocular region in dorsal view. Antennae slightly shorter ( Fig. 184 ) and with shorter antennomere XI. Pronotum wider and more transverse, approximately 1.45 times as wide as head and 1.2 times as wide as long; anteriorly more strongly narrowed; hypomera narrowly visible in lateral view. Metatarsus approximately as long as metatibia; metatarsomere I shorter than combined length of II-IV.

3: posterior margin of sternite VIII less sharply pointed ( Fig. 214 ); median lobe of aedeagus as in Figs 185-190 , ventral process split down to base ( Fig. 190 ); apical lobe of paramere slightly shorter ( Fig. 215 ).

♀: sternite VIII weakly oblong, its posterior margin as in O. collaris ( Fig. 216 ); spermatheca similar to that of O. collaris ( Figs 191-192 ).

E t y m o l o g y: The name (Lat., adj.: separate) refers to the completely split ventral process of the aedeagus.

C o m p a r a t i v e n o t e s: Like the preceding species, O. disiuncta is separated from other West Palaearctic consubgeners by the relatively narrow pronotum, as well as by the long and slender antennae and legs, and by the morphology of the aedeagus.

D i s t r i b u t i o n a n d b i o n o m i c s: This species is currently known only from one locality in Israel and from several localities in central southern Anatolia ( Map 10 ). The type specimens were sifted from grass and from the litter of trees and shrubs at altitudes of 900-1580 m. One female collected in the beginning of April is teneral. In several localities, the species was found together with O. collaris or O. longipes .
