Abstract
Rhadinoscelidia delta Liu, Yao & Xu, sp. n. (Chrysididae, Loboscelidiinae) is described and illustrated based on two female specimens from Hainan province. It represents the first record of the genus Rhadinoscelidia Kimsey, 1988 for China. A key to the world species of this genus is given. All specimens are preserved in the Hymenopteran Collection, South China Agricultural University (SCAU).
Highlights
Loboscelidiinae is a small subfamily of Chrysididae distributed in the Oriental and Australian regions (Cameron 1910, Kieffer 1916, Fouts 1925, Maa and Yoshimoto 1961, Lin 1964, Day 1979, Terayama et al 1998), which includes two genera: LoboscelidiaCopyright J
Thirty-five species in total are recognized in Loboscelidiinae (Kimsey and Bohart 1990, Kojima and Ubaidillah 2003, Xu et al 2006), of which thirty-three species belong to the genus Loboscelidia, and two species belong to the genus Rhadinoscelidia: R. malaysiae Kimsey, 1988 from Malaysia and R. halimunensis Ubaidillah, 2003 from Indonesia (Kimsey 1988, Kojima and Ubaidillah 2003)
Fouts (1922) suggested that Loboscelidiinae were probably myrmecophilous because they have the habitus of ants and the woolly appearance of the neck which is the characteristic of many myrmecophiles
Summary
Loboscelidiinae is a small subfamily of Chrysididae distributed in the Oriental and Australian regions (Cameron 1910, Kieffer 1916, Fouts 1925, Maa and Yoshimoto 1961, Lin 1964, Day 1979, Terayama et al 1998), which includes two genera: LoboscelidiaCopyright J. But species of Loboscelidiinae are probably active during dusk or nocturnally based on their dark brown body and large ocelli (Kimsey and Bohart 1990). Males of Loboscelidiinae are much more commonly collected than females (Kimsey and Bohart 1990).
