Coptostethus buci sp. n.

(Figs. 65, 130–132)

Material examined. Holotype, female: Spain, Canary Islands: “ HISPANIA Gran Canaria Los Pechos 1800–1900 m 1994. II.14–19., leg. A. Podlussány” ( HNHM).

Diagnosis. This species is near C. vittatus (H. Lindberg, 1953) for the bicoloured elytra being narrowly reddish at base but separated by the smaller body and shorter antennae only reaching the posterior angles of the pronotum.

Description. Female (Fig. 65). Entirely blackish with base of elytra from third to fifth intervals and center of scutellum reddish; antennae and legs yellow-ferruginous; covered with dense, recumbent, yellowish pubescence.

Frons convex between eyes, flat at anterior margin, this more or less regularly arcuate, puncturation coarse, contiguous.

Antennae slightly reaching posterior angles of pronotum, slightly serrate from third antennomere on, second subcylindrical, twice longer than wide and slightly shorter than third; third to tenth subtriangular, on average 2× longer than wide; last as long as penultimate, subellipsoidal.

Pronotum slightly wider than long, widest slightly before middle, strongly convex, abruptly sloping at base with a trace of a mid-longitudinal depression on basal slope; sides strongly arcuate from before middle regularly narrowing to posterior angles, latter truncate, not divergent, shortly carinate; puncturation uniformly distributed, punctures deep, simple, approximately of same sixe, with very short, shiny intervals or contiguous.

Scutellum heart-shaped, slightly wider than long, emarginate at middle of base, flat, very finely punctured.

Elytra 2× longer than and as wide as pronotum, convex, oval, widest at middle; striae well marked and distinctly punctured, interstriae flat, densely punctured.

Wings absent.

Bursa copulatrix sclerified as in Fig. 130, intermedial pieces Fig. 131 and 132.

Male unknown.

Size. Length 4.5 mm; width 1.68 mm.

Etymology. This specific epithet refers to its habitus: “ buci ” means “balloon-headed” in Hungarian.
