Psilocera kartveli László et Kelemen sp. n.

( Figs 4–5 )

Diagnosis – The female Psilocera kartveli differs from P. obscura Walker, 1833 by the length of F1 related to the pedicellus, which in P. kartveli is clearly longer, while in P. obscura is at most barely as long as ( GRAHAM 1969). It also differs from P. obscura and P. concolor (Thomson, 1878) in the shape of the third flagellar segment, which is not anelliform, nor quadrate and hardly longer than broad, in P. kartveli F1 is clearly longer than broad. The female Psilocera kartveli differs from P. crassispina (Thomson, 1878) by the setation of the basal cell: in P. crassispina basal cell of fore wing having its distal half or more pilose, while in P. kartveli the basal cell has only a few hairs distally. Psilocera kartveli females differ from P. rufipes Graham, 1992 , P. confusa Graham, 1992 and P. crassispina in the ratio of POL to OOL, which is about 0.9, while in the case of the other three species is about 0.65. Considering the species described from Asia in SURESHAN (2014) the closest species to P. kartveli are P. ghanii Subba Rao, 1981 , P. vinayaki Sureshan et Narendran, 1995 and P. namdaphaensis Sureshan, 2014 . The antennal clava of P. ghanii is shorter than three preceding segments combined, while in P. kartveli the clava is as long as three preceding segments. The scutellum of P. vinayaki has long white bristles, while P. kartveli has dark bristles. The clava of P. namdaphaensis is as long as preceding 3.5 segments combined and its scape does not reach median ocellus, while P. kartveli has a clava equal to three preceding segments its scape reaches over the lower edge of median ocellus.

The males of P. kartveli differ from P. pandens in the ratio of F1 length to pedicel length: while in P. pandens the ratio is about 3.5 ( GRAHAM 1974, GRAHAM 1992), in the case of P. kartveli the ratio of F1 is 2.4. The males of P. kartveli differ from P. punctifrons (Thomson, 1878) by the shape of F6, which in P. punctifrons is only slightly transverse ( GRAHAM 1992), but in P. kartveli is strongly transverse.

Etymology – The species name “ kartveli ” is an adjective formed from the Georgian name of Georgian person: “ kartveli ”.
