Sanmenia Song & Kim, 1992

Type species: Cupa zhengi Ono & Song, 1986 , by original designation.

Diagnosis: This genus is similar to Cupa Strand, 1906 , but can be distinguished by the combination of the following characters: body smaller than in Cupa spp.; opisthosoma nearly as long as wide [longer than wide in Cupa ]; chelicerae with three ( Song & Kim 1992) or four retromarginal teeth (this study), [two in Cupa ]; tibiae I–II each with ventral spine 2­2­2­2­2 [2­2­2­ 2 in Cupa ], metatarsi I–II each with ventral spine 2­2­2­2 [2­2­ 2 in Cupa ]; male palp with RTA and VTA separated ( Song & Kim 1992) or combined basally (this study) [single/simple RTA in Cupa ]; embolus long, originating medially on prolateral side of bulb or proximad on retrolateral side ( Fig. 7­9 ), [short and originating prolaterally to distally in Cupa ]; epigynal sclerotized plate absent [present in Cupa ].

Distribution: China, Japan, Singapore ( Fig. 10 ).

Remarks: The known single male specimen of Sanmenia kohi with one promarginal tooth may be an abnormality, considering the fact that the female specimen of this species and the other specimens of the genus all have three promarginal teeth.
