Abstract
Brephallus Wang et al., gen. n. is established as a genus distinct from Pseudophoraspis Kirby, 1903 because of the lack of a well-developed apical outgrowth on sclerite L2D and substantial genetic differences. Two species are transferred to the new genus from Pseudophoraspis, i.e., Brephallusfruhstorferi (Shelford, 1910), comb. n. and Brephallustramlapensis (Anisyutkin, 1999), comb. n. We provide a detailed generic diagnosis of Brephallus Wang et al., gen. n. Based on COI data, males, females and nymphs of three Pseudophoraspis species (P.clavellata Wang et al., 2013, P.recurvata Wang et al., 2013 and P.kabakovi Anisyutkin, 1999) were successfully matched. The former two are sexually dimorphic with macropterous males and micropterous females. Photos of the species from China are presented.
Highlights
Pseudophoraspis Kirby, 1903 is a genus of Epilamprinae cockroaches from South-east Asia whose taxonomy and biogeography were recently discussed by Wang et al (2013)
15 species are from South-east Asia (Cambodia, Thailand, Vietnam and Malaysia), and three from South China (Yunnan, Hainan)
Internal male genitalia are known for only 13 species (Anisyutkin 1999; Anisyutkin 2005; Wang et al 2013)
Summary
Pseudophoraspis Kirby, 1903 is a genus of Epilamprinae cockroaches from South-east Asia whose taxonomy and biogeography were recently discussed by Wang et al (2013). They exhibit some parental care behaviors rare among cockroaches (Tallamy and Wood 1986; Clutton-Brock 1991). Owing to the lack of research on Pseudophoraspis, this behavior in other members of the genus remains unknown. The genus is composed of 18 species (Beccaloni 2014). Only the external morphology of the remaining five species has been described, four of which are based on female specimens (Walker 1868; Hanitsch 1925, 1933)
