Diagnosis Males: palar claw broad, with rounded apex; prestrigilar flap on segment V with mesial corner produced, narrowly rounded [based on M. aleksanderi Nieser & Chen, 1999 ]; strigil absent; median lobe of sternite VII short and pointed [based on M. aleksanderi ]; free lobe of tergite VIII with mesial angle obsolete; shaft of right paramere moderately broad, with narrowly rounded apex (adapted from Lundblad 1933b ; Hutchinson 1940 ). Remarks Currently, this subgenus contains two species, M. acuta (Lundblad, 1933) and M. aleksanderi . We have assigned the latter to the subgenus Micronectella based on the absence of a strigil, the shape of the palar claw of the male, and the shape of the right paramere (see Nieser & Chen 1999 : figs 31, 38–39).
