Cryptalaus tamargrahensis sp. n.

(Figs: 3 & 6)

Material examined. Pakistan; Kheybar Pakhton Khoa Province, Tamargrah, Holotype 1 male; July-2005, leg. Rasheed, ( NHMKU); Allotype 1 female; same data as Holotype (ACP).

Measurement. (Holotype) Length 24.00 mm; width 8.00 mm. (Allotype) Length 28.00 mm; width 9.00 mm.

Coloration. Reddish - brown, sides blackish, legs and antennae blackish-brown, covered with dense vestitures.

Head. Quadrate, depressed, anteriorly; clypeus with lateral margin emarginated rounded, medially arcuate, sides angulated, deep punctures with dense vestiture at sides; antennae (Fig: 6) extended scarcely middle of pronotum, basal antennomere robust, 2nd antennomere very small, globous, 3rd antennomere smaller than 4th antennomere, 4th broader than others, remain antennomeres serrate, last antennomere spatulate with apex truncate.

Thorax. Pronotum slightly longer than broad, hind angles emarginated, acuminate, with a fine, short carina, rounded, convex in the middle, medially emarginated, side slightly flattened, anterior margin slightly emarginated medially, bisinuate, sides entire, rounded apico-median, than angulated posteriorly, circle of disc prominent laterally, deep and fine punctures with dense vestiture somewhere; scutellum lobate, depressed with deep punctures; elytra with base as broad as base of pronotum, sinuate medially, narrower behind, apices rounded, interstriae with very fine puncture, covered with dense vestiture, striae with deep, broad punctures with its length.

Male genitalia. (Fig: 4) Aedeagus with median lobe broad, elongate, evidently longer than parameres, apically slightly narrower, form a triangular, conical tip, from apex to scarcely behind, a triangular area developed by emergence of distinct angles of base of area; parameres acuminate, distance between apical margin to inner margin very less, posteriorly gradually dilated, strongly expended in base; two median struts, cord like, entire near to base of basal plate; basal plate modified, laterally expended, basal margin cord like, sclerotized.

Female genitalia. (Fig: 5) Ovipositor stout, sclerotized, paraprocts elongated, cylindrical, irregular length curved, apex only spatulated, two spermatheca arise, triangular, sclerotized margin, incomplete, attached apically to anterior most section of bursa copulatrix, sternite consist elongate shaft, medially bifurcate, distinctly away to each other posteriorly, apex truncate, basal plate broad, sheet like, rare bristles in the middle, dense on base.

Etymology. This species is named for the type locality.

Female. Similar to male, larger in body size and with shorter antennae.

Diagnosis. The new species resembles Cryptalaus enquis Candèze in the body shape, the antennae exceeding middle of the pronotum, and the hind angles of the pronotum with short carina. These species can be easily separated by 4th antennomere broader than others in C. tamargrahensis , and similar to others in C. enquis , beyond the base of elytral shoulders dull white in C. tamargrahensis but elytral shoulders dark white in C. enquis and the apices of elytra dark brown in C. tamargrahensis but the apices of elytra dull brown in C. enquis .
