Lacon brachypterus n. sp.

( Figs. 44 , 58 , 96, 127)

Material examined. Holotype ♀ - Pakistan: KP, Hazara distr. , Kaghan Valley, Naran, 2400 m, 2.VII.1986, Dacatra & Forti leg. ( CPG). 1 Paratype ♀ - same data as HT ( CPG).

Diagnosis. A species easily separated from all the known by the very small size and the reduced wings.

Description.

Female. Moderately shiny; entirely brown with ferruginous shadings; antennae and legs ferruginous; covered with moderate, recumbent, yellow-fulvous pubescence.

Frons flat, slightly impressed only at the anterior margin, this complete, subarcuate, not protruding above the clypeus; punctuation coarse, punctures deep, simple, contiguous.

Antennae short, not reaching for about three articles the apices of posterior angles of pronotum, serrated from the third article on; second article subcylindrical, as long as wide, third elongate, subtriangular, 2.3x longer than wide; fourth to tenth shorter, triangular, on average 1.5x longer than wide, the last longer than penultimate, subellipsoidal, slightly constricted before the apex.

Pronotum as long as wide, widest at middle, very convex, abruptly sloping at sides and base with a trace of mid-longitudinal impressed line on the basal slope; sides arcuate, regularly narrowing forwards and backwards, slightly sinuate before the posterior angles, the latter short, pointed, slightly divergent and feebly carinate, lateral margin complete and substraight; puntures coarse, regularly distributed, deep, simple with very short, shiny intervals.

Scutellum quadrangular, gently sinuate at sides, convex, roughly punctured.

Elytra 2.0x longer than the pronotum and as wide as it, ovaliform, widest at middle, convex, regularly rounded at the apices and with surface densely and regularly punctured, striae indistinct.

Wings reduced reaching only the middle of elytra and unable to fly.

Pronoto-sternal sutures furrowed for about the two-thirds of their length, propleurae without furrows or depressions.

Bursa copulatrix sclerified as in the Fig. 44 .

Male unknown.

Size. Length 6.00-6.10 mm; width 1.93-2.03 mm.

Etymology. The name is derived from the reduced wings of the species.
