Description: Body shiny, pitchy brownish-black, body length 2.00– 2.10 mm, body width 0.85–0.90 mm; with long, golden pubescence, sparser on elytra, dense and erect on sides of pronotum and posterior part of head and lateral part of elytra. Head about as long as wide, tempora evenly convergent posteriorly; eyes protuberant; supraantennal tubercles strongly protuberant. Antennae ( Fig. 37 ) 1.15–1.22 mm long; antennomeres III–V subspherical; VI–VII transverse, subequal in length and width, antennomere VII slightly wider than VI, ventrally prolonged by tooth; antennomere VIII 1.20 times as long as wide; IX slightly wider than long; antennomere X strongly transverse, twice as wide as long and about 0.60 times as long as IX; terminal antennomere 2.30 times as long as wide and about 3.90 times as long as X. Pronotum about as long as wide. Elytra about 1.40 times as long as wide, sutural striae reaching one fourth of elytral length. Aedeagus 0.46 mm in length, as in Fig. 38 .

Distribution: Austria, France, Italy, Slovenia.

Differential diagnosis: Euconnus similis differs from other species of the denticornis group by large body, 2.00– 2.10 mm long and strongly transverse antennomere VII which is twice as wide as long.
