Homalispa (Xanthispa) Baly 1858: 31

Synonomys

None.

Type Species

Cephaloleia cimicoides Guérin-Méneville.

Diagnosis

Homalispa (Xanthispa) can be distinguished by the following combination of characters:

· the lateral margins of the pronotumpronotum:
occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
and the elytra without long, stiff spines

· the head without a frontal horn; mouthparts projecting forward

· the pronotumpronotum:
occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
with a seta in each anterior angle

· the apex of the elytra without a tooth-like projection

· the elytra without costae, rounded, margins serrulate

· the antennae with 11-antennomeres, filiform, antennomere 3 the longest

Description

Body oval or oblong‑oval, rather flat.

Head: small; eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
elongate; fronsfrons:
upper anterior portion of head capsule above the clypeus
depressed, obliquely directed forward; labrumlabrum:
triangular, joined to the clypeus and the oral orifice
large, visible from above; mandible long, bidentate; labium large, almost as long as wide; clypeusclypeus:
usually quadrangular, elongate; joined to the labrum
short, with one narrow cross striation which is ledge‑shaped and curved upwards; mouthparts projecting forward.

Antennaantenna:
3 to 11 segments, inserted in antennal pit in front of eyes
: with 11-antennomeres, thin, filiform, inserted in a frontal depression, not separated by a keel; antennomere 3 longest.

Pronotumpronotum:
occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
: transverse; lateral margin convergent apically; anterior margin angularly pointed; narrower than elytra.

Scutellumscutellum:
sclerotized portion of the mesonotum, visible between elytral bases; usually more or less triangular, pentagonal, or quadrate
: pentagonal, cuspidate behind.

Elytronelytron:
strongly sclerotized mesothoracic wings, remaining open during flight. When closed, they cover to the last abdominal segment.  Most genera are sculptured with large punctures usually in regular rows; with various combinations of costae, carinae, spines, or tubercles; however some genera are smooth.  Lateral and apical margins are dentate, serrate or smooth.  Humerus is usually rounded but may be produced and bear spines or expansions.
: wider than pronotumpronotum:
occupies all of dorsal part of the prothorax; in anterior angles or posterior angles there may be a small tubercle or pore with a seta
, indented behind humerus; humerus impunctate; lateral and apical margins serrulate; with 10 rows of punctures plus scutellar row.
