Diagnosis

Ismarus brevis sp. nov. is quite distinct from other described Palaearctic species in antenna length and antennal segment ratios. The very short antenna and quadrate A5̅A13 are distinct characters among Palaearctic Ismarus .

Etymology

The specific epithet brevis is derived from the Latin adjective which means short.
