Diagnosis

 

Pharangispa can be distinguished by the following combination of characters:

  • lateral margin of pronotum and elytra without long, stiff spines
  • head without frontal horn between antennae
  • pronotum with seta in each angle, flattened, never constricted basally, anterior margin not prolonged over head
  • anterior margin of prosternum not projecting forward, not partly covering mouth
  • less than 14 mm in length
  • antennae with 8-antennomeres
  • elytra without longitudinal and transverse carinae forming an irregular net-like sculpture, non-costate

Description

 

Small; subparallel; bright orange with darker markings; length 4.9 to 5.9 mm.
