Masuria (M asu ria) sculpticollis sp. n.

(Figs. 27-32)

Type material:

Holotype 9: Ost-Nepal, Rolwaling Himal / Rolwaling Tal , Nyimare , 3300 m, 19.05. 2000, leg. A. Kleeberg / Holotypus 9 M asuria sculpticollis sp. n. det. V. Assing 200 6 (cAss). Paratype 9: same data as holotype (cKle ).

Description:

Species of intermediate size, 4.0- 4.3 mm. Habitus as in Fig. 27. Body blackish, with the tarsi yellowish to yellowish brown; antennae with the basal 3-4 antennomeres reddish brown and the apical antennomeres blackish brown.

Head with dense, rather coarse, and well-defined puncturation, interstices much narrower than average diameter of punctures and without microsculpture; eyes bulging, distinctly projecting from lateral outline of head (Fig. 28). Antennae moderately slender (Fig. 29); preapical antennomeres approximately 1.5 times as wide as long.

Pronotum 1.40-1.45 times as wide as head and 1.25-1.30 times as wide as long; lateral margins distinctly angled a short distance anterior to middle, more or less straight (i. e. not sinuate) between lateral and posterior angles; posterior angles well-marked; puncturation highly distinctive: very coarse, rugose, and confluent (i. e. ill-defined) everywhere; surface almost matt (Fig. 28).

Elytra approximately 1.2 times as wide and 0.9 times as long as pronotum; puncturation coarse (more so than that of head), rather dense (but less so than that of head), and welldefined; interstices on average narrower than diameter of punctures. Hind wings apparently fully developed. Metatarsus not distinctly elongated; metatarsomere I shorter than combined length of II and III (Fig. 30).

Abdomen approximately 0.85 times as wide as elytra, widest at base (segments III/IV), gradually tapering towards apex; puncturation fine, very dense on tergite III, distinctly sparser on posterior than on anterior tergites; pubescence greyish and decumbent; surface without distinct microsculpture; posterior margin of tergite VII with pronounced palisade fringe (Fig. 31).

c?: unknown.

9: posterior margin of tergite VIII broadly convex and with very long thin marginal setae; posterior margin of sternite VIII broadly convex; spermatheca not distinctive (Fig. 32), similar to that of other M asuria species.

Etymology: The name (Lat., adj.) refers to the strongly sculptured pronotum.

Comparative notes:

The species is readily distinguished from all other species of the genus by the coarsely and rugosely punctured pronotum.

Distribution and bionomics:

The types were collected in only one locality in the Rolwaling Himal at an altitude of 3300 m. Additional bionomic data are not available.
