Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 3.5 cm TL macho/indeterminado; (Ref. 52193)
Espinhos dorsais (total): 0; Raios dorsais moles (total): 7-9; Espinhos anais 0; Raios anais moles: 11 - 16. 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).
Found in small rivers, brooks, swamps and shallow lake parts among vegetated areas (Ref. 3788). Strictly a floodplain or marsh-loving species (Ref. 7248, 52193). Not a seasonal killifish (Ref. 27139). Is difficult to maintain in aquarium (Ref. 27139).
