Diagnostic Description
provided by Fishbase
Diagnosis: Lacustricola hutereaui is easily distinguished from L. chobensis and L. pygmaeus by the possession of a ventral arm in the posttemporal bone vs. ventral arm absent, a sharp ventral process in the maxilla vs. ventral process absent, retroarticular smaller than anguloarticular ventral arm vs. about the same size, a lachrymal without a posteroventral extension vs. posteroventral extension present, and by a sinuous cleithrum posterodorsal flap vs. flap rounded (Ref. 123968).Description: Scales in longitudinal series 23-25 (Ref. 28714). Lacustricola hutereaui is the only species to present the anterior portion of the infraorbital canal closed, with four pores, the mandibular canal closed, with four pores, and the neuromasts placed in deep grooves (Ref. 123968).Colouration: It is possible to note the lack of intense bluish green bright metallic colouration in the flank and the presence of an intense orange colouration in the anal, dorsal, and caudal fins (Ref. 123968).
