description: Craspedophorus hexagonus (Chaudoir, 1861)
(Figs 2, 3)
Material examined. 1♂: “N. W. / India // hexagonus Chaud. / Ex Musaeo / H.W. Bates / 1892” (MNHN, Fig. 3). Pakistan. 1♂, 1♀: “S-Asia n-Pakistan / Khyber-Pahtunkwa Prov. / Lower Dir Distr. / VII—2015 lgt. Zubair Ahmad” (cMH, Fig. 2, b). New Record.
Redescription. BL 18.2–19.0 mm. BW 7.4–8.0. Body black. Each elytron with two yellow maculae: humeral, almost circular, extending from interval III (stria II) to elytral margin, touching the margin partially but not extending beyond the epipleura, macula intersects interval III on a shorter stretch than interval IV (thus obtaining a rounded margin in the media), on intervals IV to VI the same length, on intervals VII and VIII extended towards base, on interval VIII and elytral margin macula as long as it is on intervals IV to VI (thus obtaining a rounded margin laterally), laterally from interval VIII yellow sections moved in the basal direction so that the front and back macular margins form a line at the edge of each elytron basal, both macular margins regular (not serrated); preapical macula bounded at the front edge regularly, posteriad slightly serrate, both edges forming a line slanting in the apical direction at the medial and lateral macular margin. Macula is spread out from interval IV (stria III) to VIII, elytral margin remains black (Fig. 2a, b).
Head feebly longer than wide, about half as wide as pronotum (PW/HW 2.1), strictly constricted behind eyes. Clypeus apically trunctate, smooth, just on the base finely dotted, anterior tentorial pit shallow but distinct, convex forward. Frons and vertex with a median tubercle, laterally flattened. Both vertex and lateral posterior incisions are roughly and irregularly jammed and wrinkled, both the rear before the neck constriction and the neck are smooth with distinct isodiametric microsculpture.
Eyes markedly protruding, tempora almost indistinct. Mandibles long, outer margin straight, apical margin almost rectangular, sharply curved. Mentum anteriorly broadly concave, rounded at sides. Terminal labial palpomeres triangular (male) or elongated (female). Antennae long, slightly flattened from antennomere IV, antennomere III longer, as long as the first two together (AR = 0.64: 0.36: 0.86).
Pronotum hexagonal, transverse (PW/PL 1.6), with maximum width at midlength. Anterior margin straight, parallel to base, distinctly shorter than base; anterior angles bluntly rounded but distinct, hind angles with a small ridge in front of the tip and with a tooth tapering to the side at tip; base straight. Disc slightly convex, indistinctly separated from lateral rim, which is more distinct and slightly elevated at base, narrowing and vanishing anteriad. Basal pits in hind quarter of pronotum elongate, parallel to longitudinal axis, indistinctly delimited and shallow. Medial line indistinct, shallow, disappearing near margins. Surface of the entire pronotum roughly and deeply punctured, covered with long black setae.
Elytra slightly convex, oblong (EL/EW 1.59), widest in the middle, almost ovoid, but with distinct, only topped shoulders. Striae deeply impressed, distinctly densely, relatively regularly finely punctured, intervals slightly convex, quite densely covered with punctures arranged in 3-4 rows. Side margin with wide rim, almost as wide as the interval, widest in the middle, regularly jammed along its entire length. Elytral surface with a distinct isodiametric microsculpture, covered with short setae all over the surface of elytra.
Underside covered by setae, metepisternum trapeziform, oblong anteriad (ES3L/ES3 W 1.56, Fig. 2e). Ventrites punctured and wrinkled, finely in the middle, on the sides more tough and rough, crenulation at the front edge is indistinct (Fig. 2f). Tarsi without brush-like setae, besides the usual setae on the edge.
Aedeagus is shown in both front and side views (Fig.2c, d).
Differential diagnosis. The species belongs to the C. mandarinus species group (Häckel and Kirschenhofer 2014, Fedorenko 2016) and is different from the two similar species, C. jakli Häckel and Kirschenhofer, 2014 and C. huensis Häckel and Kirschenhofer, 2014, in the shape of pronotum, especially in the distinctly toothed posterior angles.
