Pseudosphromenus

This species is most easily told apart from its only congener P. dayi by lacking (vs. possessing) two dark, irregular lateral stripes on the head and body, and a shorter caudal-fin in males. The results of phylogenetic analyses by Rüber et al. (2006) suggest that Pseudosphromenus is most closely-related to Malpulutta in an evolutionary sense.

Engmann (1909) mentions that the type series was collected from 'Malakka' but this is considered an error which probably should have read 'Kerala' since this species is known only from coastal drainages of the Western Ghats mountains in southern Kerala state, India.
