Hydaticus vittatus, is a species of predaceous diving beetle found in India, Pakistan, Sri Lanka, Nepal, Bangladesh, Bhutan, Myanmar, China, Japan, Taiwan, Thailand, Cambodia, Laos, Vietnam, Malaysia and Indonesia.[1]
The beetle has a highly variable body shape characterized by geographic variations, with a typical body length ranging from 11.3 to 14.6 mm. The head is blackish, becoming variably yellow anteriorly. The pronotum is also black, but yellowish laterally. The elytra have two bright golden yellow longitudinal lateral stripes in the basal half.[2] Large black markings occur on the elytra and pronotum. The yellow stripes on the lateral sides of the pronotum are narrow. In males, the aedeagus in lateral view lacks a longitudinal ridge near the ventral margin in the apical third.[3][4] The posterior margins of the first four segments of hind tarsi are transversely lined with a coarse fringe of flat, adpressed, golden-yellow setae.[5]
