Abstract: Ivierhipidius, gen. nov., with four new species, Ivierhipidius paradoxus sp.
nov. (Belize, Honduras), Ivierhipidius monneorum sp. nov. (Brazil),
Ivierhipidius youngi sp. nov. (Ecuador) and Ivierhipidius cechorum sp. nov.
(Argentina), are described and figured. The new Neotropical genus shares strong
similarities with the Asian Pterydrias Reitter, 1895 (= Eorhipidius
Iablokoff-Khnzorian, 1986) (currently placed in Ripidiinae: Eorhipidiini), but
most similarities consist of lack of modifications, and may be plesiomorphic. It
is placed in Ripiphoridae incertae sedis, awaiting a review of higher taxonomic
relationships within Ripiphoridae. Ivierhipidius is known only from winged
males; the female, which is assumed to be flightless, immature stages and life
history are unknown.
