Descriptions of new genera and new species of Western Hemisphere checkered beetles (Coleoptera, Cleroidea, Cleridae) Author Opitz, Weston text Linzer biologische Beiträge 2019 2019-12-20 51 2 959 1076 journal article 10.5281/zenodo.3746744 3ab3ca17-b957-454a-bdcf-d664740802e6 0253-116X 3746744 Nelsopelonium aspikelum OPITZ nov.sp. ( Figs 71 , 119 , 229 , 309 ) Holotype : ♂ . Type locality: Sta. Rita Range, Res. Pima Co. ARIZ, 2000-4000', 10 Aug. 1971 , E. Yensen ( FSCA ). D i a g n o s i s: The genus Nelsopelonium BARR was revised in 2014 ( OPITZ 2014a ). This work included a key to genera. The available Nelsopelonium aspikelum specimen keys out to N. jenae BARR from which the N. aspikelum holotype differs by showing a much smaller body size ( 4 mm ), more cribrate elytral disc, and a vastly different aedeagus. D e s c r i p t i o n: Size: Length 4.0 mm; width 1.3 mm . Form: As in Fig. 309 . Color: Castaneous, except femora infuscated at extremity, pronotal disc with small infuscation at middle, and elytra piceous, with faint lighter fascia behind middle. Head: Frons deeply indented; antenna ( Fig. 71 ) capitate, funicular antennomeres progressively shorter towards capitulum, capitular antennomeres 9 and 10 oblong, their anterior margin undulate; eyes small, coarsely facetted, eye much narrower than frons (EW/FW 15/30). Thorax: Pronotum ( Fig. 119 ) slightly convex, oblong, finely punctate; side margins linear (PW/PL 62/67); elytra moderately convex; proximal 1/2 of disc sculptured with non-striate asetiferous punctures, posterior 1/2 of disc cribrate; epipleural margin diminutive at elytral apex (EL/EW 180/40). Abdomen: Pygidium transverse/scutiform; aedeagus as in Fig. 229. N a t u r a l H i s t o r y: The holotype was collected during August. D i s t r i b u t i o n: This species is known from The United States of America . E t y m o l o g y: The trivial name, aspikelum , is a Greek compound name that stems from aspin (= shield) and kelis (= spot); with reference to the small infuscation on the pronotal disc.
