Synonomys

Physocoryna Baly 1885: 90 not Guérin-Méneville 1844 [misapplied name].

Brachycoryna Baly.

Type Species

Brachycoryna pumila Guérin-Méneville.

Diagnosis

Brachycoryna 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
• 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 with 8 rows of punctures for entire length and 3 regular costae
• the antennae thickened at apex, clavate, with 7- or 8-antennomeres
• the prosternumprosternum:
  contains two anterior coxal cavities
  does not expand anteriorly to partly cover the mouth

Description

Head: small; vertexvertex:
occupies the area behind and between the eyes
not prominent, with longitudinal sulcus; eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
not prominent, separated by more than width of an eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
; area around eyeeye:
elongate, slightly prominent, multifaceted; usually slightly kidney-shaped
, except along pit, rugose; antennaantenna:
3 to 11 segments, inserted in antennal pit in front of eyes
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; tibiatibia:
variable in length; joins femur and tarsus
and femurfemur:
largest part of the leg; more or less cylindrical, attached at base to trochanter and at apex to tibia
subequal in length; trochantertrochanter:
small, joined to base of femur
slightly angular; tibiatibia:
variable in length; joins femur and tarsus
gradually widening to apex with tuft of setae at apex; femurfemur:
largest part of the leg; more or less cylindrical, attached at base to trochanter and at apex to tibia
widest at middle.

Venter: pro‑ and mesosternummesosternum:
narrow between middle coxae, separated from metasternum by a transverse suture; forming the anterior part of the middle coxal cavities
punctate in middle, alutaceous.
