Metolinus squamifer nov.sp.

(Figs 4-6)

Examined material Holotype ♂: Thailand, Chumphong prov., Pha To env., 8.48N, 98.47E, K. Majer 1-21.III.1996 (NHMB); paratype: same data, 1♂ (cB).

Description: Length of body 3.7 mm; from anterior margin of head to posterior margin of elytra: 2 mm. Body shiny, reddish brown very dark; antennae and legs brown. Head sub-quadrangular, slightly dilated forward, with sub-parallel and sub-rectilinear sides and rounded posterior angles. Eyes large and a little protruding. Surface of head with few, very sparse punctures. Pronotum longer than head, a little dilated anteriorly where is wide as head, with very oblique anterior margins, largely rounded anterior angles and feebly sinuate sides. Surface with dorsal series of 2 anterior and 3 posterior punctures; lateral series of 2 very fine, anterior punctures. Elytra sub-rectangular, dilated posteriad, longer and wider than pronotum, with marked humeral angles. Surface with three series of very fine punctures, one juxtasutural, one median and one lateral. Abdomen without micro-sculpture, with fine and very sparse punctation.

Tergite and sternite of the male genital segment as in Figs 4-5. Aedeagus (Fig. 6) 0.81 mm long, ovoid elongate, with short, narrow parameres; inner sac with a long, narrow, left spine, next to a series of square, small scales; in the middle of the sac are present numerous square scales, roughly on two juxtaposed files, shaped like a tapered spine.

Etymology: The specific epithet is the Latin squamifer- a- um (squamous).

Distribution: The species is known only from the type locality.

Remarks: This species, for the external characters and those of the inner sac of the aedeagus, is isolated from the congeners, so it is difficult to compare with other taxa.
