Ordo: Coleoptera
Familia: Curculionidae
Name
Arostropsis Yunakov & Kirejtshuk gen. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type species
Arostropsis groehni Yunakov & Kirejtshuk, sp. n.
Etymology
The name of the new genus is formed from the Greek negative prefix “a”, “rōstron” (beak, bill, snout) and “opsis” (resembling a (specified) thing). Gender feminine.
Diagnosis
Body elongate, in general appearance similar to Pandeleteius Schoenherr, 1834. Antenna with scape short, as long as pedicel (first funicular article; term after Doyen 1966[1]) and 2nd funicular article (antennomere 3) together, reaching anterior margin of eye, strongly widened and flattened dorso-ventrally along apical third. Rostrum distinctly elongate and slender, about half as thick as frons. Vertex with small frontal fossa anterior of eyes. Buccal cavity completely covered by prementum; transverse sulcus absent. Epistome sparsely setose: only two pairs of short (internal) and long (external) setae (such composition of setae is not found among groups of Naupactini and Anypotactini); parepistome (term after Morimoto et al. 2006[2]) weakly acute and gently extending beyond contour of rostrum (Fig. 14). Antennal scrobes entirely lateral, just swinging fossa (term after Morimoto et al. 2006[2]) slightly visible from above, pterygia scarcely pronounced. Mandibular process resembling that in other Naupactini (this structure was examined for six genera of Naupactini), weakly curved inward, with distinct dorsal carina, without inner basal tooth (Fig. 18). Eyes strongly asymmetrically convex. Pronotal and elytral disk distinctly depressed dorsally. Pronotum with distinct lateral ridges; its posterior edge bisinuate. Elytra subparallel-sided, with humeral and distinct subapical prominences, elytral declivity gently sloping. Femora obtuse, weakly swollen. Metatibiae with open corbels. Claws free.
