Type Species

 

Brachycoryna pumila Guérin-Méneville.

Diagnosis

 

Brachycoryna can be distinguished by the following combination of characters:

  • the lateral margins of the pronotum and the elytra without long, stiff spines
  • the head without a frontal horn
  • the pronotum with a seta in each anterior angle
  • the apex of the elytra without a tooth-like projection
  • the elytra with 8 rows of punctures for entire length and 3 regular costae
  • the antennae thickened at apex, clavate, with 7- or 8-antennomeres
  • the prosternum does not expand anteriorly to partly cover the mouth

Description

 

Head: small; vertex not prominent, with longitudinal sulcus; eye not prominent, separated by more than width of an eye; area around eye, except along pit, rugose; antenna inserted into pit on front of head; pit divided by shallow, central keel.

Antenna: short; with 7‑ or 8‑antennomeres; basal antennomeres more or less similar, penultimate slightly expanded, ultimate forming a hirsute, oval club.

Pronotum: wider than long, narrower than elytra, convex; punctures distributed over entire surface except along apical margin; medial callus usually present on disc.

Scutellum: small; quadrate.

Elytron: oblong‑oval, longer than wide, parallel-sided; apex broadly, evenly rounded; lateral and apical margins serrate; humeral angle rounded; with 10 rows of punctures, punctures usually distinct, arranged in pairs, but sometimes becoming confused, plus scutellar row; intervals 2, 4, 6, and 8 elevated and often costate.

Leg: short; tibia and femur subequal in length; trochanter slightly angular; tibia gradually widening to apex with tuft of setae at apex; femur widest at middle.

Venter: pro‑ and mesosternum punctate in middle, alutaceous.
