Genus Songthela Ono, 2000

Type species.

Heptathela hangzhouensis Chen, Zhang & Zhu, 1981.

Diagnosis.

Songthela males can be distinguished from those of all other heptatheline genera by the conductor with the proximal portion relatively narrow, the distal portion with one or two apical spines (Figs 3B, E , 5B, E , 7B, E ); by the distal of the embolus slightly sclerotized, with a wide and flat opening (Figs 3C, D , 5A, D , 7A, D ); and by the contrategulum with a serrate margin (Figs 3C, D , 5A, D, G , 7A, D, G ). Songthela females differ from those of all other heptatheline genera by four receptacular clusters with smooth surface, the median ones with relatively long sturdy genital stalks, four receptacular clusters along the anterior margin of the bursa copulatrix or the lateral ones situated dorsolaterally (Figs 3H-J , 5H , 8A-D , 8I-L , 9A-D ).

Distribution.

China and northern Vietnam.
