Description: Body shiny, reddish-brown, body length 1.85–1.90 mm, body width 0.75–0.80 mm; with long, golden pubescence, sparse on elytra, erect on sides of pronotum and posterior part of head. Head about 1.10–1.20 as wide as long, tempora evenly convergent posteriorly; eyes protuberant; supra-antennal tubercles strongly protuberant. Antennae ( Fig. 35 ) 0.95 mm long; antennomeres III–VI subequal in length and width; antennomere VII subtrapezoidal, 1.3 times as wide as long; antennomere VIII 1.30 times as long as wide, about 2.15 times as long as VII and slightly shorter than IX, terminal antennomere 1.80 times as long as wide and 2.10 times as long as subquadrate antennomere X. Pronotum slightly wider than long. Elytra about 1.40 times as long as wide, sutural striae reaching basal third of elytral length. Aedeagus 0.39 mm in length, as in Fig. 36 .

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

Differential diagnosis: Euconnus puniceus differs from other species of the denticornis group by body size, 1.85–1.90 mm long, subquadrate antennomere X and antennomere VIII he is 1.30 times as long as wide. E. puniceus is similar to E. denticornis but it differs in a lighter colour, slightly larger and different structure of aedeagus.
