Type material. Holotype 1 Ψ: “ PAPUA NEUGUINEA, Morobe Prov., Wau, Mt. Kaindi, 07°22"S [sic!], 146°40'E, 2200 m, 17.II.2000 leg. A. Weigel KL”. The holotype will be deposited in NMEG.
Description. Length 10.9 mm; width 2.9 mm. Body robust, cuneiform, convex; upper side silky lustrous, head and pronotum greenish­black, elytra violet­black; ventral side mat, violet­black, abdomen shiny purple.
Head: frontovertex convex with broad, deep medial longitudinal sulcus extending from epistoma to vertex, surface densely, coarsely punctate; vertex 2.1 times as wide as width of eye; eyes large, convex, not protruding beyond head outline, lower margin of eye distinctly extends beyond upper margin of antennal socket. Antennae rather short, barely extending to pronotal midpoint when laid alongside, antennomeres 4–5 sharply serrate, antennomeres 6–10 obtusely serrate.
Pronotum: 1.8 times wider than long, trapezoid, strongly convex, widest at base; anterior margin without medial lobe, almost straight, distinctly narrower then posterior margin; anterior pronotal sides straight converging anteriorly; disk sparsely, coarsely, transversely rugose with broad medial longitudinal impression extending from posterior almost to anterior margin; lateral impressions absent. Prehumerus long, sublinear, sharp and rib­like, originating from posterior margin in close vicinity of posterolateral angles and conjoined with lateral margin in anterior fourth of pronotal length. Marginal and submarginal carinae feebly sinuate, converging posteriorly, submarginal carina becoming obsolete in anterior and posterior parts.
Scutellum: 1.3 times longer than wide, narrowly subquadrate in front, sharply triangular behind, without transverse carina, feebly impressed on disk.
Elytra: 3.2 times longer than wide, widest at base, gradually tapering beyond middle then abruptly attenuate to apices; lateral margins of apices slightly expanded, apex sinuately emarginate, emargination with series of adsutural denticles and sharp spine on outer angle; disk with obvious, broad adsutural impression covered with golden toment in apical third. Humeri without costa.
Last tergite: with long medial spine on apex, ventrally visible between emargination of elytral apices.
Ventral side: prosternal lobe declivous, arcuately emarginate at middle; prosternal process large, distinctly converging between coxae, than abruptly subovally expanded; disk flat, roughly densely punctate. Last ventrite very narrow, evenly arcuate apically, with indication of faint notch. Ventrolateral parts of thorax and abdomen clothed with long, decumbent, white pubescence.
Legs: Metatarsi shorter than metatibiae; basal metatarsomere 1.2 times longer as three following together; tarsal claws cleft near middle, inner tooth shorter and broader.
Diagnosis. Closely related to A. paradiseus from which differs by 1) long, medial pronotal impression; 2) straight prehumerus; 3) adsutural elytral impression with golden toment reaching to apices; 4) lateral margin of apices slightly expanded and 5) apices arcuately sinuate.
Etymology. The specific epithet, a noun in the genitive case is named for my dear friends Mrs. Iveta and Mr. Tibor Mikušiak.
