Microhoria fergana Kejval , sp. nov.

( Figs 98, 99 )

Type locality. Kyrgyzstan, Osh District, 15 km SW of Osh, 40°23′N 72°46′E, 1150 m.

Type material. HOLOTYPE:, ‘ Kirgisistan: Oshaskaya, Distr. Osh, trockene Steppenhügel , 15 km SW Osh, 40°23′N 72°46′E, 1150 m, 26.VI.1996 [p] // 96/12 [p] // Microhoria mollis (Desbrochers) det. G. Uhmann 1997 [p+h]’ ( ZSMC) . PARATYPES: 1 ♀, same data as holotype, lacking 2 nd label ( ZSMC).

Description. Male (holotype). Body length 2.2 mm. Body brown, elytra unicolorous; legs brown, tibiae moderately paler; antennae brown, slightly darker distally.

Head 1.1 times as long as wide, nearly evenly rounded posteriorly; eyes small, distinctly convex. Surface moderately glossy, minutely punctate and slightly shagreened; punctures distinctly spaced; setation short, subdecumbent, few short erect setae posteriorly.Antennae only moderately enlarged for apical third; antennomeres X 1.6 times, XI 4.0 times as long as wide.

Pronotum 1.1 times as long as wide, distinctly narrower than head including eyes, evenly rounded anteriorly, pronotal disc evenly and moderately convex, outline in dorsal view with lateral margins slightly impressed posteriorly. Surface moderately glossy, punctate, slightly shagreened; punctation and setation as on head, with some very short erect setae.

Elytra 1.6 times as long as wide, subparallel, somewhat flattened; humeri distinctly protruding; apices modified, channel of gland forming short tubular process at apical margin. Surface moderately glossy, densely punctate; punctation and setation slightly coarser than on head, with scattered short erect setae.

Legs simple; all tibiae with paired terminal spurs.

Abdominal sternum VII simple; tergum VII simple; tergum VIII with distinct, laterally angled flange posteriorly ( Fig. 99 ); sternum VIII forming paired subtriangular sclerites that are rounded apically. Aedeagus ( Fig. 98 ): tegmen narrowed apically, distinctly hooked in lateral view; endophallic armature with pair of short, robust, moderately curved sclerites and numerous slender spines.

Female. Identical with male for most external characters; elytral apices simple; sternum VII simple; tergum VII simple, evenly rounded apically.

Differential diagnosis. Microhoria fergana sp. nov. belongs to the M. terminata species-group. It may resemble M. nicolasi from Turkmenistan (‘Transcaspia’), but differs by the widely flanged and somewhat sinuous posterior margin of male tergum VII, and by characters of the aedeagus (more slender and simply hooked apex of tegmen, numerous slender spinules in endophallus).

Etymology. Named after the Fergana valley in Kyrgyzstan; noun in the nominative case, standing in apposition.

Distribution. Kyrgyzstan.
