Succinctonotum Gordon and Hanley, 2017

Gordon, Robert D. & Hanley, Guy A., 2017, South American Coccinellidae (Coleoptera), Part XVII: systematic revision of Western Hemisphere Cephaloscymnini (Coccinellinae) with description of a cryptic new genus and species of Coccidulini (Coccinellinae), Insecta Mundi 2017 (601), pp. 1-158 : 50

Succinctonotum Gordon and Hanley , new genus

Description. Cephaloscymnini with body form short, widely oval, narrowed from apex of pronotum to apex of abdomen. Frons narrow, widened from vertex to apex, widest point nearly as wide as eye; apex of frons not extended beyond antennal insertion; male clypeus and anterior portion of frons pale yellow or yellowish white, not densely pubescent ( Fig. 308 ); female head without maculation. Apical maxillary palpomere slender, narrowed from middle to apex as in Neaporia . Pronotum short, about two times as long as scutellum, with anterior margin deeply excavated for reception of head, with oblique surface groove as in Neaporia , strongly projected forward laterally to midpoint of eye ( Fig. 308 ). Prothoracic hypomeron without fossa. Epipleuron narrow, flat. Male pro–, meso– and metasterna mostly flat except weak depression between pro– and mesosterna; prosternum short, wide, without lateral carina, apex without modified setae. Male metasternum without pit medially adjacent to metepisternum. Tarsal claw without basal angulation. Apex of male 5th ventrite arcuate.

Remarks. This genus is thus far known from two specimens. It is recognized by the short body; pronotum only slightly longer than scutellum medially; narrow, elongate head; and flat, unmodified prosternal process. The male is described below and female genitalia of the other specimen are also described, but the female is not designated as a type because it cannot be determined with certainty that these specimens are the same species. Succinctonotum is similar to Neaporia , sharing the same pronotal groove and lack of prosternal carinae.

Etymology. The genus name refers to the short pronotum of the type species; gender feminine.
