Type species.

Diplacanthogaster bicolor Liebke, 1932

Way of life.

Size range - 7.0 mm to 9.0 mm; the single species of this genus is active in April, July, and August, and probably in proximity of water.

Distribution.

Brazil.

Notes.

Reichardt (1967) regarded this genus as congeneric with Stenocheila Laporte de Castelnau. However, his study shows he had no male specimens of the latter for comparisons. We have presented in the key to genera above the attributes that justify Liebke’s separation of the two genera and not Reichardt’s synonymy.
