Anthaxia (Haplanthaxia) puchneri sp. nov.

( Figs 6 , 12 , 23 )

Type locality. Angola, Prov. Huila, Caconda – Huambo road, near Nova Monçaõ, 1640 m, 13°262ƍS – 015°227ƍE. Type specimen studied. HOLOTYPE: J, ދ Angola, Prov. Huila, Str. zw. Caconda u. Huambo, Umgb. Nova Monçaõ, 1640 m, S13°262’–O15°227’, 8.–12.xi.2012, leg. A. Puchner ތ ( NMPC).

Diagnosis. Medium-sized (8.0 mm), convex, strongly wedge-shaped, bronze with silky lustre ( Fig. 6 ); frontoclypeus with green lustre, tarsi and distal antennomeres (5–11) black; ventral surface bronze, lustrous; dorsal surface asetose, frons with rather dense, white, semi-erect pubescence; ventral surface with sparse, white, recumbent pubescence; metepimera and lateral parts of ventrites with patches of condensed cream-white pubescence.

Description. Male (holotype). Head large, as wide as anterior pronotal margin; anterior margin of frontoclypeus rather deeply, triangularly emarginate; frons flat, inner margins of eyes strongly S-shaped; vertex flat, 0.7 times as wide as width of eye; eyes large, reniform, slightly projecting beyond outline of head; sculpture of frons consisting of dense, irregular, small cells without distinct central grains; antennae short, reaching midlength of lateral pronotal margins when laid alongside; scape claviform, curved, 4.5 times as long as wide, pedicel subcylindrical, 1.2 times as long as wide; third antennomere triangular, 1.5 times as long as wide, fourth antennomere obtusely triangular, as wide as long; antennomeres 5–10 obtusely trapezoidal, somewhat longer than wide; terminal antennomere rhomboid, 1.5 times as long as wide.

Pronotum rather convex, 1.7 times as wide as long with ¿ne, transverse depression in middle; lateroposterior depressions wide, shallow; anterior margin rather strongly, posterior weakly biarcuate; lateral margins subparallel, regularly rounded both anteriorly and posteriorly, posterior angles obtuse; sculpture consisting of short, transverse rugae at disc, and small, regular, dense polygonal cells with small central grains along lateral margins and in lateroposterior depressions. Scutellum cordiform, concave, somewhat wider than long.

Elytra regularly convex, strongly wedge-shaped, twice as long as wide; humeral swellings small, transverse basal depressions shallow not reaching scutellum; apical quarter of elytral margins sparsely serrate, each elytron rounded separately; elytral epipleura narrow, parallelsided, nearly reaching elytral apex; sculpture homogeneous consisting of ¿ne punctures along suture and ¿ne, very dense, transverse rugae on reminder of elytra.

Ventral surface lustrous, prosternal process flat, strongly enlarged posterior to procoxae; anal ventrite truncate apically, ¿nely, densely serrate laterally. Legs slender, relatively long, protibiae strongly, mesotibiae slightly curved; apices of mesotibiae slightly enlarged; metatibiae ( Fig. 23 ) straight, somewhat flattened with large tooth in apical ¿fth of inner margin. Tarsal claws ¿ne, slightly hook-shaped, very slightly enlarged at base.

Aedeagus ( Fig. 12 ) long, slender, parameres nearly parallel-sided with small, knoll-like elevation in posterior third of ventral surface; median lobe very slender, sharply pointed apically, without lateral serration.

Sexual dimorphism. Female unknown.

Measurements. Length: 8.0 mm; width: 2.8 mm.

Differential diagnosis. Anthaxia (H.) puchneri sp. nov. is very similar to A. (H.) mashuna from which it differs only in distinctly slender body, slightly in the form of male metatibiae ( Figs 23 vs. 24) and ¿rst of all in the different male genitalia ( Figs 12 vs. 13).

Etymology. This species is named in the honour of its collector, Alfred Puchner, Vienna, Austria.

Distribution. Angola (Huíla Province).
