Abstract

A 579 base-pairs fragment of the cytochrome b gene has been sequenced for the four Heterobranchus species, four Clarias species, and Channallabes apus (Clariidae). Clarotes laticeps (Claroteidae) was used as outgroup. Results support the hypothesis that Heterobranchus is monophyletic. Clarias, however, appears to be paraphyletic.
