Diagnosis.

To be recognized by the shape of the pronotum with spine-like posterior angles, by scattered and fine punctation of the pronotum, by only six elytral rows of punctures extinguished in the posterior and external part of elytra, and by the shape of the aedeagus. The two other known species of Mimolaena possess nearly rounded posterior angles of the pronotum, and the punctation on the pronotum is either fine and the elytra bear punctural rows ( Mimolaena pauliani Ardoin, 1961), or the punctation on the pronotum is rough and dense and the elytra bear an dense irregular punctation not separated in rows and intervals ( Mimolaena clarissae Ferrer, 1998). See also key below.

Description.

Body length 3.5-4.7 mm, unicoloured dark brown. Eyes (Fig. 8) not reduced, slightly prominent. Shape of the antennomeres see Fig. 8. Shape of pronotum see Fig. 8, disc with a few scattered punctures, most punctures bearing a longer erect seta; surface without any impressions, surface shining, lateral margins bordered, basal margin bordered and not bent downwards, posterior angles prominent spine-like, propleura unpunctured. Elytra (Fig. 8) with only six punctural rows without striae, these rows extinguishing in posterior and external part of elytra, punctures of rows of similar size as pronotal punctures, punctures of the elytral rows without setae, a few additional punctures apart from the rows laterally and distally on the elytra bear a longer erect seta, intervals shining without any punctures and setation, intervals flat. Ventrites shining, in males with fine punctation and short setation, in females nearly unpunctured and without setation, last ventrite in both sexes unbordered. Femora and tibiae in both sexes without teeth or other modifications. Aedeagus see Fig. 14.

Etymology.

Named in honor of J. Janák, one of the collectors of the type series and of other Malagasy Laenini .
