Euconnus (Tetramelus) kerpensis MEYBOHM View in CoL nov.sp. ( Figs 31 View Fig , 33-34 View Figs 32-37 )

T y p e m a t e r i a l: Holotype 3: " Greece: Karpathos [12], S Olympos, 35°43'19''N, 27°10'19''E, 460 m, shrub litter sifted, 26.XII.2015, V. Assing / Euconnus (Tetramelus) kerpensis m. Meybohm 2016 det. / Holotypus " (cMey). Paratypes: 13, 3♀♀: same data as holotype (cMey).

E t y m o l o g y: The specific epithet is an adjective derived from Kerpe, the Turkish name for Karpathos.

D e s c r i p t i o n: Body length 1.1 mm. Habitus as in Fig. 33 View Figs 32-37 . Coloration pale reddish-brown. Pubescence suberect and directed posteriad. Head 0.12 mm long and 0.19 mm broad. Eyes reduced to approximately four ommatidia with weakly pronounced pigmentation. Antenna short, 0.46 mm long, with the apical four antennomere forming a distinct club; antennomeres III-VI as long as broad; antennomeres IX and X twice as broad as long. Pronotum 0.28 mm long and 0.24 mm broad, broadest in the middle; basally with four impressions, the two median impressions larger than the lateral ones, separated from each other and from the posterior margin by approximately their diameter, and connected by a shallow transverse furrow. Elytra 0.64 mm long and 0.43 mm broad, broadest anterior to middle; with two small basal pits; humeral angles obsolete. Profemur much more strongly dilated apically (club-shaped) than meso- and metafemur. Metaventrite with sexual dimorphism, more strongly impressed in male than in female.

3: aedeagus ( Fig. 34 View Figs 32-37 ) 0.29 mm long and 0.14 mm broad; dorsal plate scoop-shaped, symmetric (except for a shallow lateral concavity), with a longitudinal structure of similar shape and orientation as internal sclerites; endophallus with two long and slender sclerites, the shorter one more strongly bent and with a short lateral process above the middle; ventral plate with wing-shaped, prominent lateral processes; parameres apically with two long and bent setae, subapically with a shorter staight seta.

C o m p a r a t i v e n o t e s: Euconnus kerpensis is reliably distinguished from other similar Tetramelus species only by the shape and internal structures of the aedeagus.

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: Like all other named Scydmaeninae recorded from Karpathos, E. kerpensis is endemic to the island. The type locality is identical to that of Cephennium kerpense . The specimens were sifted from very dry litter beneath shrubs near large rocks in phrygana vegetation at an altitude of 460 m ( Fig. 31 View Fig ).
