Chordodes mizoramensis (Nematomorpha, Gordiida), a new species of horsehair worm from Mizoram, North-East India

Abstract

Chordodes mizoramensis, a new species of freshwater gordiid horsehair worm, is described from Mizoram, NE India on the basis of scanning electron microscopic and morphometric studies. Th e new species can be distinguished from its congeners in that the apical fi laments of the crowned areoles are branched several times, a pattern that has not been observed in other species. An additional distinguishing character is that it has more bulging areoles, which are distributed among simple areoles alone or in groups, do not form clear patterns. © A. Schmidt-Rhaesa, Lalramliana.
