( Figs. 33–34 )

Euconnus (Cladoconnus) pseudorobustus Franz, 1986: 41 . Type locality: Schio Mquime südlich des Kuratales und östlich von Tbilisi in etwa 1000 m Höhe.

Material examined (3 3): HOLOTYPE, 1 3: GEORGIA: white label (p) Umg. Tiflis [=Tbilisi], Kaukasusvorberge, 1000–1200m / red label (h) Holotypus / white label (h) E. (Cladoconnus) pseudorobustus m.

(p) det. H. Franz / red label (p) HOLOTYPE Euconnus (Cladoconnus) pseudorobustus Franz, P. Hlaváč det., 2012. (NHMW). Additional material: TURKEY: (2 3): (p) 23.06.2003, NE Turkey, N Ikizdere, S Rize, leg. P. Bialooki., (PJWP, PHKS).

Description: Body shiny, dark reddish-brown, pronotum pitchy black, body length 1.75 mm, body width 0.75; with long, golden pubescence, sparse on sides of elytra becoming less towards elytral disc where it is completely absent, erect on sides of pronotum and posterior part of head. Head slightly wider than long, tempora evenly convergent posteriorly; eyes protuberant; supra-antennal tubercles gently protuberant. Antennae ( Fig. 33 ) 0.85 mm long; antennomere III aboutv as long as wide; antennomeres IV–VI transverse, subequal, antennomere VII transverse 1.45 times as wider as long and slightly wider than VI; antennomere VIII about 1.85 times as long as wide, about 3.75 times as long as VII and 1.65 times as long as IX; terminal antennomere 1.85 times as long as wide and twice as long as transverse antennomere X. Pronotum 1.10 times as long as wide. Elytra about 1.30 times as long as wide, sutural striae reaching basal third of elytral length. Aedeagus 0.40 mm in length, as in Fig. 34 .

Distribution: Georgia, Turkey (Rize Province).

Differential diagnosis: Euconnus pseudorobustus differs from other species of the denticornis group by small body, 1.75 mm long and by having transverse antennomeres IX and X, antennomere IX 1.20 times as wide as long and X 1.40 times as wide as long.

Note: The aedeagus of this species is very similar (almost identical) to that of E. denticornis . We decided to maintain it as a separate species due to a clearly different structure of the antennal club, especially the antennomere VIII which is much longer and more slender than that in E. denticornis .
