Anthomorphus fraudulentus Voss, 1960: 150  .

Type locality. Kandahar ( Afghanistan).

Type series. Anthomorphus fraudulentus  was described based on a single specimen from Southern Afghanistan, Kandahar - Kuna. I examined one female specimen from coll. Voss ( ZFMKAbout ZFMK) labeled “ Holotypus [red printed] / Anthomorphus (Persexarthrus) fraudulentus E. Voss  det. 1956 n.sp. [red asterisk] / J. Klapperich Kandahar – Kuna 1200 m, 1.3. 53 S-Afghanistan / Anthomorphus fraudulentus Voss, 1959  [folded label]”. I dissected its genitalia and added a label “Michael Košťál reprep. 2013 ”. This specimen fully corresponds to the original description and there is no doubt it is the holotype. The holotype is 2.94 mm long, completely preserved, with right elytron disjointed.

Redescription. Female ( Fig. 22View FIGURES 14 – 22). Length 2.9 mm. Body: moderately slender, very slightly broadened posteriorly. Rostrum: yellowish, long (Rl/Pl = 1.31); in lateral view regularly curved, uniform in width from base to apex; in dorsal view with parallel sides to antennal insertion, upper sides markedly emarginate at rostrum base making lateral rostral grooves visible here, in distal part first slightly narrowed and then slightly broadened to apex, shiny, densely finely punctured from base to apex, in basal quarter with few seta-like recumbent scales. Head: frons broader than rostrum at base and of same width as rostrum at apex, very densely and finely sculptured, with white seta-like scales directed laterally; eyes prominent. Antennae: Yellowish red with slightly darkened club, inserted slightly behind middle of rostrum length; funicular segment 1 2.3 x longer than wide, segment 2 hardly longer than wide; club spindle-shaped, about twice as long as wide. Pronotum: yellowish, with medium sized rounded punctures, intervals between punctures of about same width as diameter of punctures; on sides of disc and in anterior part of midline with sparse whitish recumbent seta-like scales forming narrow medial white line restricted to anterior part of pronotum; transverse (Pw/Pl = 1.36), broadest shortly in middle, with subparallel sides in middle part of pronotum length, visibly constricted after anterior margin, weakly convex at the disc. Elytra: Yellowish; moderately long (El/Ew = 1.46), subparallel, widest after 1 / 2 of length, flat on disc. Striae and interstriae visible on the majority of their surface. Whitish recumbent seta-like scales clustered on elytral base, between second and third 1 / 3 of elytral length forming a band, on interstriae 4–5 shortly before apex forming a patch and on apex itself. Elytra with scattered scales among densely squamose parts of elytra. Legs: Entirely yellowish, covered with whitish recumbent, on posterior femoral side at base nearly upright long white seta-like to hair-like thin scales; profemora with large triangular tooth and anteapical emargination ( Fig. 4View FIGURES 1 – 4); tarsomere 3 very small, emarginate, of same width as tarsomere 2, onychium of the same length as tarsomeres 1–2 combined; claws simple. Venter: Regularly covered with white seta-like scales, medial part of metasternum, ventrite 1 and 2 with fine dense transverse furrowing and clearly visible, small round punctures. Spermatheca: Fig. 13.

Variability. There is only a single female known of this species.

Diagnosis. This species is easily recognizable by its large profemoral teeth and very narrow tarsomere 3 as well as by a very short funicular segment 2.

Comparative notes. Anthonomnus fraudulentus  is most closely related to A. baudueri  , from which it differs by narrow tarsomere 3 and a globose funicular segment 2 that is slightly longer than wide.

Biological notes. No available data.

Distribution. Afghanistan.

Non-type material examined. None.
