Abstract

Two species of cockroaches were collected from aquatic habitats of undisturbed natural forest streams in Nepal and India (Maharashtra): Rhicnoda natatrix and Rhicnoda rugosa. Nymphs and adults are depicted and field observations of microhabitat and behavior described. Taxa lists of accompanying macroinvertebrate fauna are given, and water quality class is calculated using three biotic scoring systems. R. natatrix is a true aquatic species with amphibious lifestyle in the eulittoral of springs (Crenon) and streams (Rhithron) of excellent and good water quality classes I and II. R. rugosa is a predominantly terrestrial species that also colonizes the banks of water bodies and appears in between aquatic fauna. These species cannot be classified using the traditional habitat system.
