Qiongthela baishensis Xu, 2015. Diagnosis. Males of Qiongthela can be distinguished from those of all other six Heptathelinae genera by the blade-like conductor narrowing towards the apex (Figs 3A-C, E , 5A-E , 7A-E ), and by the tegulum with two obvious apophyses (Figs 3A-E , 5A-E , 7A-E ). Females of Qiongthela differ from those of all other six Heptathelinae genera by the two pairs of the receptacular clusters with numerous granula (Figs 3H-K , 5H-K , 7H-M ) ( Xu et al. 2017 ; Yu et al. 2020 ).
