1. Trechus asiaticus Jeannel, 1927 View in CoL

Material examined: Bulgaria: 1♂, Yambol, Bolyarovo Vill., Samar daalu cave I, 05.06.2005, P. Stoev leg. ( NMNHS)

Additional comparative material examined: Greece: 1♀, 2♂♂, Chios Isl. , Ayio Georgios [St. George], 25– 26.06.1935, (coll. J. Fodor, HNHMB) ; 1♂, Kephallinia, A. Winkler (coll. R. Jeannel, MNHN) ; Turkey: 1♂, Lycie : Taurus (Hauser) (coll. Jeannel, MNHN) ; 1♂, Asia minor, Alem Daghi, von Bodemeyer; 1♂, Constantinople (coll. Jeannel, MNHN)

Notes: Relatively large: the body length of males is 4.44–4.84 mm ( Pawlowski 1973); in our sample, it was

3.9–4.6 mm. The body’s dorsal surface is dark brown, usually with easily visible prolonged humeral and oval spots before the apex on the elytra. In some specimens, the elytra are unicolourous. Wings well developed, partly or fully reduced. Usually, the pronotum base is wide, the basal margin is longer than the length of the pronotum (index PWB/ PL ≥ 1.2), but in some cases, the index is lower. The aedeagus does not differ from those illustrated and described by Jeannel (1927: 444) and Pawlowski (1973: 242). Its apex is strongly curved downward in lateral view. The copulatory piece is slightly concave in the middle.
