Heptathela hangzhouensis Chen, Zhang & Zhu, 1981. Diagnosis. Males of Songthela differ from those of all other Heptathelinae genera by smooth conductor with one or two apical spines and by conductor middle portion having several teeth (Figs 3B, E , 4A-C , 6A, B ); by embolus having a wide and flat opening (Figs 3D , 4D , 6D ); and by contrategulum having densely serrated margin (Figs 3D , 4D , 6D ); females of Songthela can be distinguished from those of all other liphistiid genera by two pairs of receptacular clusters separated from each other, median ones with obviously tubular genital stalks, four receptacular clusters situated at the anterior margin of the bursa copulatrix, or middle ones situated at the anterior margin of the bursa copulatrix and lateral ones located relatively dorsolaterally, or all four located dorsally (Figs 3J-M , 5A-F , 7A-H ). Distribution. China (Chongqing, Guizhou, Hubei, Hunan, Sichuan, Yunnan, Zhejiang) and Vietnam (Lao Cai).
