Euconnus goerzensis Reitter, 1894: 101 . Type locality: Salvano env. De Görz. Euconnus (s.str.) goerzensis Reitter : Ganglbauer, 1899: 49.

Euconnus (Cladoconnus) goerzensis Reitter : Franz, 1964: 158, Fig. 30 ; Franz, 1971b: 301, Fig. 25 ; Karaman, 1974: 140, Fig. 30 .

Material examined (4 3, 1 Ƥ): CROATIA: 1 3: Plitvitzer Seen, 10– 23.8.1975, leg. Brachat (HMGG). BOSNIA & HERZEGOVINA: 2 3: Igman – Gb. Apfelbeck (HNHM). SERBIA: 1 3, 1 Ƥ: Tara Planina, Zaovine, 920m, 28.x.2008, leg. M. Stevanoviċ (PHKS).

Description: Body shiny, reddish-brown, body length about 1.95 mm, body width about 0.80 mm; with long, golden pubescence, shorter but even pubescence on whole surface of elytra, longer, dense and erect on sides of pronotum and posterior part of head. Head slightly wider than long, tempora evenly convergent posteriorly; eyes protuberant; supra-antennal tubercles strongly protuberant. Antennae ( Fig. 15 ) 0.95–1.05 mm long; antennomere III about as long as wide; IV–VI subequal, slightly transverse; VII 1.50 times as wider than long, wider than VI; antennomere VIII about 1.15 times as long as wide; IX slightly wider than long; antennomere X subquadrate; terminal antennomere 1.70 as long as wide, about 1.80 times as long as X. Pronotum slightly longer than wide. Elytra about 1.35 times as long as wide, sutural striae reaching basal fifth of elytra. Aedeagus 0.39 mm in length, as in Fig. 16 .

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

Differential diagnosis: Euconnus goerzensis differs from other species of schlosseri group by large body, about 1.95 mm long, antennomere IX slightly wider than long, X subquadrate, symmetrical. E. goerzensis is most similar to E. pulcher , both are largest species of the schlosseri group, but it is readily separated from late by shorter terminal antennomere which is only 1.70 times as long as wide, while in E. pulcher it is about twice as long as wide.
