Zhou, Yan-Chen, Yuen, Yan Ling & Zhang, Zhi-Sheng, 2017, A new Bifidocoelotes species, with the description of the male of B. primus from Hong Kong, China (Agelenidae: Coelotinae), Zootaxa 4232 (3), pp. 429-436 : 430

Genus Bifidocoelotes Wang, 2002

Diagnosis. The most remarkable and unique character distinguishing this genus from other coelotines is the anterio-mesally originated, long, single and bifurcated epigynal teeth ( Figs 1 A, 2C, 3A, 4C; Wang 2002: fig. 86). Male pedipalps of Bifidocoelotes can be recognized by a bifurcated or spiral conductor ( Figs 1 D, 2F, 3D, 4F, 5; Wang 2002: fig. 88). The bifurcated conductor (of B. obscurus and B. bifidus ) somewhat similar to that of Alloclubioides pseudonariceus ( Zhang, Zhu & Song, 2007), but each branch of conductor is simple and unmodified. The spiral conductor (of B. primus ) is similar to that of Spiricoelotes , but extending retrolateroproximally, rather than apically.

Composition. Three species, B. bifida ( Wang, Tso & Wu, 2001) , B. obscurus sp. nov. and B. primus ( Fox, 1937) .

Distribution. Known from Hong Kong and Taiwan, two islands of South China.
