Name
Trigonopterus rufibasis Riedel sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnostic description
Holotype, male (Fig. 73a). Length 2.38 mm. Color black; basal 1/3 of elytra ferruginous; legs dark ferruginous except tarsi, knees and base of femora black. Body subovate; with weak constriction between pronotum and elytron; in profile almost evenly convex. Rostrum dorsally relatively flat, with two submedian rows of punctures, dorsolaterally with pair of furrows continuing along eye. Pronotum sparsely punctate with minute punctures, subapically punctures larger and denser. Elytra with striae distinct, dorsally punctures small, along base and laterally behind humeri punctures large; intervals subglabrous. Femora edentate. Metafemur with simple dorsoposterior edge; subapically with stridulatory patch. Aedeagus (Fig. 73b) apically rounded, sparsely setose; transfer apparatus spiniform, curved, much shorter than body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.91–2.55 mm. Color of legs ferruginous or black. Female rostrum dorsally with punctures smaller and sparser than in male.
Material examined
Holotype (MZB): ARC1764 (EMBL # HE616041), WEST NEW GUINEA, Jayawijaya Reg., Poga, S03°47.575', E138°33.155' to S03°47.473', E138°33.163', 2620–2715 m, 15-VII-2010. Paratypes (SMNK, ZSM): WEST NEW GUINEA, Jayawijaya Reg., Poga: 12 exx, ARC1765 (EMBL # HE616042), ARC1766 (EMBL # HE616043), same data as holotype.
Distribution
Jayawijaya Reg. (Poga). Elevation: ca. 2620–2715 m.
Biology
Beaten from foliage of upper montane forests.
Etymology
This epithet is based on the combination of the Latin adjective rufus (reddish) and the noun basis (base) and refers to the elytral coloration.
