Cypha truncata nov.sp. ( Figs 6-7 )

T y p e m a t e r i a l: Holotype: " Ukraine, Odessa, Kuyalnik estuary opp. Protopopovka , 27.X.2005, leg. Gontarenko / Holotypus Cypha truncata sp. n. det. V. Assing 2014" (cAss).

E t y m o l o g y: The specific epithet (Latin, adjective) alludes to apically truncate ventral process of the aedeagus.

D e s c r i p t i o n: Body length 1.7 mm; length of forebody 0.8 mm; length of antenna 0.6 mm. External characters as in C. tarsalis , distinguished only by the morphology of the aedeagus.

: median lobe of aedeagus ( Figs 6-7 ) 0.35 mm long and compact; ventral process strongly curved (lateral view), relatively short in relation to basal portion of median lobe, and apically truncate (ventral view); crista apicalis strongly prominent.

C o m p a r a t i v e n o t e s: Cypha truncata is distinguished from the similar and evidently closely related C. tarsalis by the smaller median lobe of the aedeagus ( C. tarsalis : approximately 0.4 mm), with a less strongly sclerotized, shorter, more strongly curved, subapically carinate (lateral view), and apically truncate ventral process.

D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The type locality is situated in the Odessa region, Ukraine, close to the coast of the Black Sea.
