Loktak Lake

Within this assemblage P. manipurensis is most similar to 'P.' meingangbii and P. padamya by virtue of the fact that males in all three possess orange-red pigmentation on the flanks and caudal-fin. It can be told apart most easily by the fact it possesses a relatively small, spot-like humeral marking, vs. a vertically-elongated, relatively large humeral marking in both the other species.
