A new species and notes on the genus Aphelocheirus (Hemiptera: Heteroptera: Aphelocheiridae) from China

Abstract

This paper provides the description of a new species, Aphelocheirus menglaensis sp.nov. from Yunnan Province. A. gularis Horváth, 1918 and A. inops (Horváth, 1918) are reported from China for the first time. We also reviewed A. ellipsoideus Liu & Ding, 2005, include its macropterous forms and brachypterous female. Dorsal habitus photographs of the new species and A. ellipsoideus are provided and are accompanied by illustrations of male genitalic structures of both species and the ventral aspect of posterior abdominal segments of the female of only the new species.

Report on antennal sensilla ofAphelocheirus ellipsoideus(Hemiptera, Heteroptera, Aphelocheiridae)

“…The family Aphelocheiridae is distributed exclusively in the Old World and reaches its greatest species richness in the Oriental Region (Sites et al, 2011). It is represented by a single genus Aphelocheirus , with 104 species currently described in the world (Basu & Subramanian, 2016; Basu et al, 2013; Liu & Ding, 2005a, 2005b; Liu & Zheng, 1994, 2000; Nieser & Chen, 1991; Nieser & Millán, 1989; Nieser et al, 2004; Polhemus, 1994; Polhemus & Polhemus, 1989, 2013; Sites, 2005; Sites et al, 2011; Thirumalai, 2007, 2008; Tran & Nguyen, 2016; Xie & Liu, 2014, 2015; Zettel et al, 2008; Zettel, 1993, 1998, 1999a, 1999b, 2000, 2001, 2003, 2012; Zettel & Pangantihon, 2010; Zettel & Tran, 2009). Aphelocheiridae have four‐segmented antennae, the antennae in Aphelocheiridae are easily visible since they are not concealed.…”

“…Up to now, 27 species of the genus Aphelocheirus (Supporting Information: Figure ) were known from China (Liu & Ding, 2005a, 2005b; Liu & Zheng, 1994, 2000; Xie & Liu, 2014, 2015). Many species of Aphelocheiridae have both macropterous and brachypterous forms of individuals.…”

“…The uncommon macropterous forms, which are often quite different structurally from the more common brachypterous morphs, are now known for the majority of the species (Polhemus & Polhemus, 1989). Aphelocheirus ellipsoideus (Liu & Ding, 2005a, 2005b) macropterous and brachypterous forms were reviewed in Xie and Liu (2015).…”
