Discussion.

Distigmoptera was first recorded in the West Indies by Medvedev (2004) who described a new species from the Dominican Republic. Fourteen previously described species of this genus are known to occur in the USA, Canada, Mexico, and Costa Rica. Among the West Indian genera of Monoplatini, Distigmoptera is mostly similar to Apleuraltica Bechyné. Apart from characters mentioned in the key (see below), Distigmoptera can be differentiated from Apleuraltica by the antennae that are not clearly clubbed, antennomere six in males is only slightly different from antennomere seven (the antennae are clearly clubbed, antennomere six in males is markedly different from antennomere seven in being much shorter and narrower than seven in Apleuraltica ) and by the metatibial apex without a sharp denticle (the metatibial apex has a sharp denticle in Apleuraltica ).
