Female provided with ventro-anal plate and preanal setae. Posterior portion of peritremal plate not fused with parapodal plate. Spermatophoral process thick and long, more than two times of the length of chela.Type species: Bulbogamasus sinicus gen. et sp. nov. Species diagnosis as above (figs. 1-17).Holotype ♀ and 1 paratype ♀ were collected on 24. Ⅵ. 1987, allotype ♂ and 6 paratypes ♀♀ on 7.
