Euconnus (Cladoconnus) croaticus sp. nov.

( Figs. 27–28 )

Etymology: named after Croatia, country of its discovery.

Material examined (1 3): HOLOTYPE, 13: white label (p) CROATIA: Istra, Dane, Ćiċarija, Novačka špilja, 28: VII.01, R. Ozimec lgt. / red label (p) HOLOTYPE EUCONNUS sbg. Cladoconnus croaticus n. sp., Hlaváč & Stevanoviċ det., 2011. (CNHM).

Description: Body shiny, reddish-brown, legs and maxillary palpi lighter, body length 2.00 mm, body width 0.81 mm; with sparse, long pubescence, denser on tempora and sides of pronotum, present also on pronotal and elytral disc. Head slightly wider than long, tempora evenly convergent posteriorly; eyes strongly protuberant; supra-antennal tubercles weakly protuberant. Antennae ( Fig. 27 ) 1.0 mm long; antennomeres III 1.10 times as long as wide; IV–VII transverse, IV small, V–VI subequal, VII 1.50 times as wide as long; antennomere VIII about 1.70 times as long as wide, about 3.15 times as long as VII and 1.25 times as long as IX; antennomere IX 1.05 times as long as wide; X 1.20 times as long as wide; terminal antennomere 2.00 times as long as wide and about 1.65 times as long as X. Pronotum 1.15 as long as wide. Elytra about 1.45 times as long as wide, sutural striae very short, marked just at base of elytra. Aedeagus 0.47 mm in length, as in Fig. 28 .

Distribution: Croatia (Istra).

Differential diagnosis: Euconnus croaticus differs from other species of denticornis group by very short sutural striae, just at base of elytra, by large body, 2.00 mm long, antennomere III 1.15 times as long as wide, very long antennomere VIII which is 1.70 times as long as wide, terminal antennomere twice as long as wide. E. croaticus is similar to E. kiesenwetteri , it differs from late by longer antennomere VIII which is 1.70 times as long as wide, about twice as long as wide for E. kiesenwetteri .
