Description: Body shiny, lighter reddish-brown, body length 1.55–1.60 mm, body width about 0.65 mm; with long, golden pubescence, sparse on elytral and pronotal disc, dense and erect on sides of pronotum and posterior part of head. Head slightly wider than long, oval; eyes very large, protuberant; supra-antennal tubercles strongly protuberant. Antennae ( Fig. 23 ) 0.80–0.85 mm long; antennomeres III subquadrate, 1.10 times as wide as long; IV–VI transverse, subequal in length and width; VII subtrapezoidal, 1.55 time as wide as long; slightly larger and wider than VI; antennomere VIII about as long as wide; IX slightly wider than long; antennomere X subtrapezoidal, about 1.20 times as wide as long and only 0.85 times as long as IX; terminal antennomere 1.50 times as long as wide and about twice as long as X. Pronotum slightly longer than wide. Elytra about 1.3 times as long as wide, sutural striae reaching basal fourth of elytra. Aedeagus 0.33 mm in length, as in Fig. 24 .

Distribution: Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, Slovenia, Serbia.

Differential diagnosis: Euconnus schlosseri differs from other species of schlosseri group by small body, 1.55–1.60 mm long, antennomere III subquadrate, slightly transverse, antennomere X which is only 1.20 times as wide as long and mainly by very unique shape of aedeagus with truncate apex. E. schlosseri is similar to E. anatolicus and E. meybohmi , but readily distinguished from both by subtrapezoidal antennomere X, which is about 1.20 times as wide as long, the head slightly wider than long and longer sutural striae, reaching basal fourth of elytra.
