Qiongthela males can be distinguished from all other Heptathelinae genera by the blade-like conductor narrowing to a slightly hooked apex (Fig. 2 M-O ; Fig. 4 F-J ), and by the tegulum with two distinct apophyses (Fig. 2 L-O ; Fig. 4 F-J ). The females differ from all other Heptathelinae genera by two paired receptacular clusters, all with numerous granula (e.g. Fig. 1 C-H ) ( Xu et al. 2015b ). Species composition.
