Discussion. This species has a characteristic coloration in life, consisting of a blue-black body with a pale chevron mark on the posterior scutellum. The degree of expression of the angular process distally on the male hind femur, a diagnostic character for the species, is intraspecifically variable.

The complicated nomenclatural history of this species is reviewed in detail by Lansbury (1968) and is not repeated here.

Ecological notes. Enithares ciliata is an adaptable and widespread species that in addition to stream pools will also utilize artificial habitats, such as reservoirs and abandoned swimming pools. The recorded distribution of this taxon extends from Mauritius, Ceylon, India and Bhutan eastward through Thailand, Vietnam, Cambodia, peninsular Malaysia and Sumatra ( Lansbury 1968, D. Polhemus 2017). Nieser et al. (2008) provided extensive additional records for this species in Thailand, and the material listed above includes new records for Laos, Burma, Java and Borneo.
