It superficially resembles Atopochilus savorgnani, and is known to co-occur with this species at several localities. This new taxon can be distinguished from all other chiloglanidin species by a combination of features including robust mandibular teeth arranged in transverse rows that are approximately 66% of the width of the paired premaxillary tooth patches, and the presence of an anteriorly directed cavity located dorsal to the lower lip and ventral to the oral cavity.

This relatively small species (<50 mm SL) is distinguished from all congeners by a distinctive pigmentation pattern that includes a pair of dark patches on the caudal fin and by the presence of hypertrophied opercular spines in sexually mature males.

Two of the species, Chiloglanis igamba sp. nov., and Chiloglanis orthodontus sp. nov. are restricted to the Malagarasi basin. The third species, Chiloglanis kazumbei sp. nov., is more broadly distributed in both the Malag- arasi and adjacent Luiche basin. A key to all described species within these two basins is presented, along with comments on the distribution and validity of nominal Chiloglanis species examined during this study.
