Microhoria halophila Kejval , sp. nov. ( Fig. 103 )

Type locality. Turkey, NW of Tuz Gölu Lake, Kulu env..

Type material. HOLOTYPE:, ‘ TURKEY centr., Tuz Gölu , Kulu, 29.v.1996. M. Snížek lgt. [p]’ ( NMPC) . PARATYPES: 4 2 ♀♀, same data as holotype ( ZKDC); 1, ‘ TURKEY centr., Kulu env., 14.v.2002, J. Hlásek lgt. [p]’ ( ZKDC).

Description. Male (holotype). Body length 3.1 mm. Body black, basal margin of pronotum and elytra with brownish tinge; legs dark brown, tibiae paler, reddish-brown; antennae black, unicolorous.

Head 1.2 times as long as wide, widely rounded posteriorly; eyes small, moderately convex. Surface moderately glossy, distinctly and rather densely punctate; punctures distinctly spaced; setation short, subdecumbent.Antennae slightly enlarged for apical third; antennomeres X 1.1 times, XI 2.5 times as long as wide.

Pronotum 1.1 times as long as wide, robust, slightly narrower than head including eyes, evenly rounded anteriorly, pronotal disc evenly convex, outline in dorsal view with lateral margins moderately impressed posteriorly. Surface moderately glossy, distinctly punctate; punctation and setation as on head (punctures at most slightly denser).

Elytra 1.6 times as long as wide, moderately convex, subtruncate posteriorly; humeri absent; apices modified, channel of gland forming short tubular process at apical margin. Surface moderately glossy, densely punctate; punctation shallower than on head; setation short, subdecumbent; with scattered short, suberect tactile setae.

Legs simple; all tibiae with paired terminal spurs.

Abdominal sternum VII simple or at most very slightly emarginate medially; sternum VIII forming paired subtriangular sclerites that are rather rounded posteriorly. Aedeagus ( Fig. 103 ): narrow apical portion of tegmen moderately widened subapically and hooked apically; endophallic armature with two robust and about ten slender, simple, moderately long, straight spines.

Female. Identical with male for most external characters; elytral apices simple; sternum VII distinctly emarginate apically; tergum VII truncate apically.

Variation. Body length (♀) 2.8–3.1 mm.

Differential diagnosis. Microhoria halophila sp. nov. belongs to the M. terminata species-group. It can be distinguished from all apterous/brachypterous species distributed in Anatolia by its robust appearance, dark colouration (entirely unicolorous black), and rather coarse punctation. Its aedeagus resembles that of M. inobscura stat. nov. (see Figs 103 , 109 ), but the apical hook of the tegmen is more prominent and the endophallic armature is quite different.

Etymology. From the Latin halophila (halophilous); referring to its distribution near Tuz Gölu Salt Lake; adjective.

Distribution. Turkey.
