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.
