Hlaváč, Peter & Stevanović, Miroslav, 2013, A review of the subgenus Cladoconnus Reitter of the genus Euconnus Thomson (Coleoptera: Staphylinidae: Scydmaeninae) from the Balkan Peninsula, Turkey and Caucasus, Zootaxa 3646 (4), pp. 401-425 : 408-409

Euconnus (Cladoconnus) gagranicus sp. nov.

( Figs. 13–14 )

Euconnus (Cladoconnus) robustus Reitter : Franz, 1975: 33 (misidentification).

Etymology: named after Gagra, village in Abkhazia, Georgia, where the species was discovered.

Material examined (1 3): HOLOTYPE, 1 3: GEORGIA: ABKHAZIA: white label (p) CAUCASUS, Gagra env. - VI.R. Rous lgt. 1971. / white label (h) Euconnus robustus Rtt. 3, (p) det. H. Franz / red label (p) HOLOTYPE, EUCONNUS sbg. Cladoconnus gagranicus n. sp., Hlaváč & Stevanoviċ det., 2011 (NHMW).

Description: Body shiny, reddish-brown, legs and maxillary palpi lighter, body length 1.65 mm, body width 0.70 mm; pubescence very sparse and visible mainly on sides of head and pronotum, almost absent on dorsum of head, pronotum and elytra. Head slightly wider than long, tempora evenly convergent posteriorly; eyes slightly protuberant; supra-antennal tubercles weakly protuberant. Antennae ( Fig. 13 ) 0.73 mm long; antennomere III slightly longer than wide; IV–VI transverse, subequal in length and width; VII transverse, 1.90 times as wide as long; antennomere VIII about as long as wide; IX transverse, about 1.50 times as wide as long; antennomere X strongly transverse, about 1.60 times as wide as long and about 1.25 times as short as IX; terminal antennomere 1.60 as long as wide and about 2.55 times as long as X. Pronotum slightly longer than wide. Elytra about 1.35 times as long as wide, sutural striae long, reaching basal third of elytra. Aedeagus 0.34 mm in length, as in Fig. 14 .

Distribution: Georgia (Abkhazia).

Differential diagnosis: Euconnus gagranicus differs from other species of schlosseri group by small body, about 1.65 mm long, transverse antennomere IX, 1.50 as wide as long, and transverse antennomere X, about 1.60 times as wide as long. E. gagranicus is most similar to E. ispartaensis but it differs from the latter by having terminal antennomere XI 1.60 times as long as wide, only 1.35 times as long as wide in E. ispartaensis and by different aedegus.

Note: The specimen from Gagra used by Franz (1975) for the redescription of E. robustus is not conspecific with this species and it represents a new species which is described here above.
