Genus Sinanapis Wunderlich & Song, 1995

Sinanapis Wunderlich & Song, 1995: 344. Type species: Sinanapis crassitarsa Wunderlich & Song, 1995.

Diagnosis. Sinanapis can be distinguished from all other anapidae genera by the following combination of characters: 1) a small proximal tubercle on anterior surface of chelicerae ( Figs 11, 13 ); 2) the presence of even short cusps on metatarsus and tarsus of leg I ventrally ( Figs 12, 14 ); 3) palpal patella long, structure complex, with several apophyses ( Figs 27–33 ). This genus is similar to Minanapis Platnick & Forster, 1989 in male palp, but differs in: 1) embolus encloses

This genus is differ from Gaiziapis in female epigynum: 1) copulatory ducts long, hover versus curved in the middle in Gaiziapis ( Figs 20, 22 , 24, 26 ); 2) copulatory opening at the posterior margin of epigynal area versus at the edge of epigynal area in Gaiziapis ( Figs 21, 23 , 25 ); 3) spermathecae globular or calabash versus clubbed in Gaiziapis ( Figs 20–26 ); 4) fertilization ducts distinct versus inconspicuous in Gaiziapis ( Figs 22 , 26 ).
