amrishi (Makhan, 2009) comb. nov.

Motonerus amrishi Makhan, 2009: 1 . – Suriname, Kasikasima.

Distribution. Suriname.

Note. Based on the photograph of the male genitalia published in the original description, the aedagus differs distinctly from the typical shape present in all Motonerus species (see FIKÁČEK & SHORT 2006) and agrees well with the genus Oosternum in all characters seen in the photographs. For that reason, the species is transferred here to the genus Oosternum .
