Iran , 2400 m 8 km NE Ziaran 10.- 16.7.1977 // Loc. no. 400 Exped. Nat. Mus. Praha // Tenuicomus luristanicus (Pic) det. G. Uhmann 1986 [p]’ ( NMPC ) . PARATYPES : 1, same data as holotype , but lacking third label ( NMPC ). Description. Male ( holotype ). Body length 2.6 mm . Body dark brown, elytra unicolorous ( Fig. 151 ; legs and antennae dark brown, tibiae and tarsi slightly paler. Head rather elongate, 1.4 times as long as wide, widely rounded posteriorly, tempora subparallel; eyes mediumsized, moderately convex. Surface moderately glossy, minutely but distinctly punctate and largely shagreened; punctures well-spaced; setation short, appressed to subdecumbent. Antennae moderately enlarged for apical half; antennomeres X 1.2 times, XI 2.4 times as long as wide. Pronotum about as long as wide, slightly narrower than head including eyes, evenly rounded anteriorly, pronotal disc evenly and moderately convex, outline in dorsal view with lateral margins nearly straightly narrowing posteriorly. Surface moderately glossy, distinctly punctate and shagreened; setation and punctation as on head, with some very short erect setae. Elytra 1.7 times as long as wide, somewhat flattened medially in basal half; humeri distinctly protruding; omoplates slightly indicated; apices modified, channel of gland forming short tubular process at margin. Surface moderately glossy, distinctly punctate; punctation and setation slightly coarser than on head, with scattered short erect setae. Legs slender, simple; all tibiae with paired terminal spurs. Abdominal sternum VII produced, truncate to slightly emarginate apically; sternum VIII forming paired sclerites, conspicuously, narrowly produced and rounded apically ( Fig. 91 ). Aedeagus ( Fig. 95 ): tegmen with simple, narrowly rounded apex; endophallic armature with pair of robust, hook-like spines and apical bunch of slender spinules. Female . Unknown. Variation. Head and pronotum more or less glossy, varying in distinctness of microsculpture. Differential diagnosis. Microhoria bacillisternum sp. nov. belongs to the M. terminata species-group. It can be easily recognized by the combination of an elongate head and its male abdominal characters, especially by the peculiar shape of the paired sclerites of sternum VIII ( Fig. 91 ). Etymology. Composed from the Latin words bacillum (rod, stamen) and sternum , named in reference to the conspicuous projections of male sternum VIII. Noun in the nominative case, standing in apposition. Distribution. Iran .
