Curculionoidea (weevils) of New Caledonia and Vanuatu: Basal families and some Curculionidae Author Kuschel, Guillermo John T. Huber text Mémoires du Muséum national d'Histoire naturelle 2008 197 99 250 journal article 978-2-85653-605-6 1243-4442 Orthorhinoides humboldtensis n. sp. Fig. 94 DESCRIPTION. — Integument black or dark brown, shiny. Scaling moderately dense, yellowish grey on dorsal surface, ochrous on sides of prothorax, elytra and sterna, vestiture on legs, abdomen and middle of sterna white, vaguely variegate on elytra where usually with a band on middle; head, forehead and rostrum with lineal, piliform scales only and no dark dots anteriorly on head. Head for most part alutaceously dull, slightly asperous and punctate. Forehead flat. Eyes posteriorly and laterally surrounded by a distinct sulcus, appearing more convex than usual for the genus. Rostrum moderately thick, slightly curved, shorter than prothorax; postrostrum in male coarsely, rugosely punctate and dull, in female finely punctate and shiny; prorostrum transverse in male, quadrate in female. Prothorax gently rounded on sides, not or indistinctly bisinuous at base, convex, coarsely granulate. Scutellum small, white if scales large, grey if scales minute. Elytra cylindrical, not or very slightly wider than prothorax, nearly twice as long as wide, with inistinct shoulders and callus, broadly rounded or subtruncate at apex; striae fine, interstrsiae flattish, with sparse granules as or almost as wide as interstriae, interstria 4 with 12-14 granules. Fore coxae narrowly disjunct; fore femora relatively robust; fore tibiae in male distinctly narrower than femora, with a blunt tooth opposite femoral tooth, then asperous on lower edge, with a small, acute premucro; in female fore tibiae strongly compressed, as wide as femora, with dorsal edge blunt, with a broad shallow furrow on either side, smooth on lower edge, with small, blunt premucro but seemingly larger due to a deep emargination between it and a large, thick uncus; hind tibiae with weakly curved dorsal edge and moderately curved lower edge, with a small, sharply pointed tooth. Length: 6.8-7.8 mm . TYPE MATERIAL . — Holotype male, 6.8 x 2.5 mm , Mt. Humboldt , data as above , NZAC . Paratypes with NZAC , SRFP . MATERIAL EXAMINED . — New Caledonia . 4 males , 1 female , Mt. Humboldt , 950 m , 10.II.2005 , on Myrtaceae, S. Cazères & C. Mille. 5 specimens . HOSTPLANTS. — Adults beaten from a species of Myrtaceae . ETYMOLOGY. — A patronymic name. REMARKS. — In appearance not unlike O. ambiguus and O. caledonicus because of lacking an oblique pale line across elytra and not having a prescutellar design on prothorax. It differs from O. ambiguus by lacking a prosternal canal, and from O. caledonicus by lacking distinct shoulders.
