Diagnosis

The female of Andromma ophiophagum sp. nov. is characterized by the epigyne with transversely reniform copulatory openings surrounded by a sclerotised area and by the long copulatory ducts.

Etymology

The species name ophiophagum is an adjective referring to the king cobra, Ophiophagus hannah Cantor, 1836 , because the spermatheca and the insemination duct together resemble a king cobra coming out of a basket.
