Habitus as in Fig. 15 View FIGURES 15–17 . Body reddish-brown, with distinctly paler elytra (mediobasal part of elytra slightly darkened); mouthparts, antennae and legs yellow-brown; tarsi yellowish. Head with dense transverse microsculpture, finer between anterior margin of eyes, coarser and isodiametric in middle and mediobasal portions, isodiametric on infraorbital portions; neck with coarse isodiametric sculpture; pronotum with dense isodiametric meshes, denser in basal portion; scutellum and elytra without distinct microsculpture; abdominal tergites with dense transverse microreticulation. Punctation of head moderately dense and fine, larger on infraorbital portions; neck with indistinct, sparse and fine punctation; neck with dense punctation, larger and deeper than that on infraorbital portions, finer in middle, interspaces between punctures in middle about as long as diameter of nearest puncture; scutellum with several fine punctures; punctation of elytra moderately dense and large, finer in middle, larger and deeper in mediolateral and lateral portions; punctation of abdominal tergites fine and dense. Pubescence of forebody yellow, dense and moderately long, semierect, longer on head; abdomen with dense decumbent pubescence.

Head 1.3 times as broad as long, with convex infraorbital portions; anteriomedian depression deep and wide, trapezoidal; interocellar depression rectangular, moderately deep; mediobasal part without constriction, slightly swollen and connected with neck; anteocellar foveae moderately deep, narrow; strongly convergent latero-apicad toward level of anterior third of eyes; temples convex, slightly shorter than longitudinal length of eyes. Ocelli small and indistinct, located slightly below level of posterior margins of eyes; distance between ocelli about 1.7 times as long as distance between ocellus and posterior margin of eye. Apical maxillary palpomere distinctly shorter and narrower than preceding segment, from about middle gradually narrowed toward rounded apex. Antenna reaching apical third of elytra when reclined; basal antennomere broadened, about four times as long as broad, antennomere 2 significantly shorter and narrower than basal antennomere, 3 slightly less than twice as long as 2, 4–7 shorter than 3, 8–9 slightly shorter than 7, 10 shorter than 9, apical antennomere 1.4 times as long as 10, from apical third gradually narrowed toward subacute apex.

Pronotum slightly convex, trapezoidal, 1.3 times as broad as long, from widest anterior third strongly narrowed posteriad toward rounded hind angles; anterior margin widely sinuate in middle, slightly shorter than somewhat straight posterior margin; basal portion transversely impressed; middle part with narrow line-like impression; lateral margins slightly crenulate, slightly stronger in latero-apical parts; lateral portions narrowly impressed.

Elytra slightly convex, about as broad as long, broadened posteriad, 1.9 times as long as pronotum; lateral margins narrowly flattened and slightly reflexed; hind margins widely rounded. Hind wings fully developed.

Metatarsi more than twice as long as metatibia.

Abdomen narrower than elytra, with two large transverse tomentose spots in middle of abdominal tergite IV and two small oval spots in middle of tergite V; apical margin of abdominal tergite VII with narrow palisade fringe.

Male. Posterior margin of abdominal tergite VIII truncate. Posterior margin of abdominal sternite VIII widely sinuate. Aedeagus with moderately broad basal portion, gradually narrowed toward median lobe; preapical part of median lobe strongly narrowed toward elongate apical portion with subacute apex; parameres narrow, curved laterally, slightly broadened in apical parts, each with two long apical and several shorter preapical setae, and inner margin with short setation; dorsal lobes narrow, sclerotized and elongate; internal sac moderately narrow and long, with two fields of sclerotized spines in middle, with sclerotized triangular structure slightly below middle and long flagellum, spirally folded in basal portion, with significantly thickened endophallic part in its basal portion ( Fig. 8 View FIGURES 4–9 ). Lateral aspect of the aedeagus as in Fig. 9 View FIGURES 4–9 .

Female unknown.

Comparative notes. Based on the general shape of the body and the aedeagus, T. haarlovi is somewhat similar to T. penicillatus ( Reitter, 1900) , widely distributed in the Middle Asia (see below), from which it can be distinguished by the crenulate margins of the pronotum, the slightly narrower elytra, distinctly narrower apical part of the the median lobe, longer parameres, and other details of the external and internal morphology of the aedeagus.

Distribution. Trichodromeus haarlovi is known only from the type locality in central Afghanistan.

Bionomics. Any bionomical data are unknown.

Remarks. Geodromicus (s.str.) haarlovi was originally described based on a single male ( Fig. 15 View FIGURES 15–17 ) from “… Sutra in Afghanistan …”. Shavrin & Klimenko (2008) transferred it to the genus Trichodromeus .
