Peribalus (Asioperibalus) classeyi (Hoberlandt, 1984) [The correct authorship is Putshkov, 1965.—Ed.]

Holcostethus classeyi Hoberlandt, 1984: 103 .

Diagnosis. The parandria are situated clearly above the horizontal level of the lateral angles of the pygofer. The species differs from the closely related Asian species in its coarse, black, rather dense punctation and spherical spermathecal bulb; laterotergite IX is very large, strongly widened toward the base.

Description. Body yellowish brown, with coarse dense black punctation. Margins of pronotum and apex of scutellum yellowish. Underside of body pale yellow, with sparser black punctation. Antenna pale, with darkened apical segment. Abdominal segments yellow, with dark spots in anterior and posterior corners of tergites. Length of body 8.5–9.8 (9.18) mm, b. lw 1.68–1.77 (1.73).

Head trapeziform ( Fig. 89 ) [h. wl 1.13–1.19 (1.16)], small, l. bh 4.05–4.61 (4.42). Jugae converging, covering apex of clypeus, slightly emarginate before eyes. Eye medium-sized, ds 1.4–1.46 (1.42). Antenna of medium length, l. ba 1.99–2.16 (2.08).

Pronotum transverse [p. wl 2.15–2.33 (2.2)], with straight lateral margins, without costa, flattened at sides, with rounded lateral angles. Scutellum of subequal length and width, s. lw 0.95–1.13 (1.03).

Male genitalia. Parandria situated clearly above horizontal level of sharply rounded lateral angles of pygofer, latter with superficial, rounded median emargination ( Fig. 66 ). Aedeagus as in Fig. 46 (when not straightened). Theca with small lateral processes. Parameres in form of overturn “L,” with rounded sensory lobe. Uneven area of inner surface of paramere narrowed toward base ( Fig. 70 ).

Female genitalia. Spermatheca with small spherical bulb bearing processes and with sclerotized duct narrowed toward base ( Fig. 11 ). Laterotergite IX very large, strongly widened toward base; sternite IX long and narrow, with shallowly emarginate lower margin and pointed apices ( Fig. 106 ).

Distribution. E Afghanistan, [Tajikistan—Ed.]: Badakhshan.
