Phlugis chrysopa Bolívar, 1888

Alogopteron carribbeum Rehn, 1903 (subjective synonym) The predatory katydid Phlugis chrysopa is distributed in the Caribbean. Another species, Alogopteron carribbeum Rehn, 1903 from Costa Rica, has been synonymized shortly after the description with Phlugis virens (Thunberg, 1815) by its author (Rehn 1905). The type locality of this latter species is unknown and it was proposed to be a synonym of Ph. chrysopa (Nickle 2005). However, a species of Phlugis distributed in the area of the famous Iguazú Falls, on both the Brazilian and the Argentine sides, has recently found to agree with the description of Ph. virens, used by previous authors for Phlugis specimens from Brazil and after all the third-oldest species name in the genus, although based on an indistinctive female holotype (Fianco et al. 2022, Braun 2023). According to the distribution it seems much more appropriate to consider A. carribbeum, also based on a female specimen, a synonym of Ph. chrysopa.
