A revision of Neomegalotomus (Hemiptera: Alydidae)

We recognize two species in Neomegalotomus, N. parvus (Westwood), the type species; and N. rufipes (Westwood). The two species are redescribed from type specimens, and are keyed. We synonymize the following species with Neomegalotomus parvus: N. simplex (Westwood), N. latifascia (Berg), and N. pallescens (St?l) (all new synonymies). We synonymize N. jamaicensis (Westwood) with N. rufipes (new synonymy). The type specimens of all species hitherto placed in the genus are also redescribed, except those of N. debilis (Walker) and N. vicinus (Westwood). N. parvus occurs from México through Central America into northern Argentina and east into Venezuela and adjacent Caribbean islands. N. rufipes is widespread in the Caribbean south towards Venezuela. The two species overlap in distribution: N. parvus is found on St. Vincent and Tobago, whereas N. rufipes occurs on Grenada, which lies between those two islands.
