Diagnosis.

Males of this species can be distinguished from males of other Thelcticopis species by its unique bases of RTA with seven or eight stiff setae, long and standing in line (almost the same length as dRTA) and tip of RTA with one stiff seta bending backwards in retrolateral view (Fig. 2A-D ). Females are similar to those of Thelcticopis picta (Thorell, 1887) in having median septum somewhat heart-shaped with a tongue-like posterior structure pointing in the direction of the epigastric furrow ( Jäger 2005: figs 1-7), but distinguished from the latter by the following characters: anterior part of the median septum with a longitudinal ridge (absent in T. picta ); ends of internal duct system inconspicuous in dorsal view (visible in T. picta ) (Fig. 2A-F ).

Description.

See Hu and Ru (1988) and Yin et al. (2012).

Distribution.

China (Guangdong, new province record; Guangxi; Hainan; Fujian, new province record; Hongkong; Hunan; Taiwan; Yunnan; Zhejiang); Korea; Japan; Laos (Fig. 5 ).
