Lin, Mei-Ying & Holzschuh, Carolus, 2013, Blamada rubripronota, a new genus and species of the tribe Saperdini (Coleoptera: Cerambycidae: Lamiinae) from Southeast Asia, Zootaxa 3640 (1), pp. 95-100 : 95-96

Blamada gen. nov.

Type species: Blamada rubripronota sp. nov.

Diagnosis. Differs from all other saperdine genera by the scape of antennae with an expanded and ridged ring at apex, and second antennomere being relatively longer (more than 1/4 of scape in length). It also differs from Eutetrapha , Paraglenea , Heteroglenea (as defined in Lin et al., 2009) and Pareutetrapha by the male claws simple instead of appendiculate (special or normal) or bifid and from Eumecocera and Stenostola by elytra with lateral carinae and male claws simple instead of appendiculate or bifid. The combination of the following characters makes the new genus easily separable from other saperdine genera: prothorax without lateral tubercles, elytra with distinct lateral carinae, elytral apex rounded, male and female claws all simple.

Description. Small-sized (under 15 mm). Head broad with tumid eyes ( Figs 2 h, 3h, 4h, 5h), frons broader than long or as broad as long, eyes deeply emarginate, not divided. Antennae longer than body, basal segments fringed with dense setae, scape slightly expanded, with an expanded and ridged ring at apex ( Figs 8–10 ), 2nd antennomere relatively long (more than 1/4 of scape in length), 3rd antennomere always the longest, 4th antennomere subequal to scape, 4th to 10th slightly and gradually decreasing in length, 11th longer than 10th. Prothorax cylindrical, without lateral spine or tubercle. Elytra subparallel, rounded apically, each with one distinct lateral carina starting from the base but not reaching the apex ( Figs 2, 4 b). Procoxal cavity closed posteriorly ( Fig. 12 ), metepisternum more than twice as wide anteriorly as posteriorly, hind femur reaching fourth abdominal segment. Both male and female with simple claws.

Etymology. The generic name is an arbitrary combination of letters. Gender feminine.

Distribution. Southeast Asia.
