Abstract
Two new species of the genus Fulvius Stål are described from the Philippines and Papua New Guinea. A taxonomic review of representatives of the F.bifenestratus species group, illustrations of the male genitalia, a color habitus image of each species, and a key to species of the group are provided.
Highlights
Fulvius Stål, 1862 is a morphologically diverse, speciose genus, with more than 80 valid species worldwide; most are found in the tropical and subtropical regions (Gorczyca 2006; Schuh 2002–2013)
Each species of the bifenestratus group can be distinguished from other Old World species of Fulvius, members of the anthocoroides group, by several characters
The membranous structure between the second valvulae is always absent in the bifenestratus group, and always present in species of the anthocoroides group (Sadowska-Woda et al 2008)
Summary
Fulvius Stål, 1862 is a morphologically diverse, speciose genus, with more than 80 valid species worldwide; most are found in the tropical and subtropical regions (Gorczyca 2006; Schuh 2002–2013). This genus is assumed to be paraphyletic and to lack consistent diagnostic characters. Based on an analysis of morphological characters, Sadowska-Woda (2005) and Gorczyca (2006) proposed three species groups for a more adequate classification of the genus Fulvius. The anthocoroides, bifenestratus, and bis bistillatus (occurring in the New World) groups were supported by preliminary DNA sequencing data from only a few congeners (Sadowska-Woda et al 2008). Scanning electron micrographs showing selected structures of F. bifenestratus Poppius, F. subnitens Poppius, and F. tumidipennis sp. n. and a key to species of the bifenestratus group are provided
