Pristidia Deeleman-Reinhold, 2001

Pristidia Deeleman-Reinhold, 2001: 182 (type species by original designation, Pristidia prima Deeleman-Reinhold, 2001 ); World Spider Catalog 2017.

Diagnosis. Pristidia resembles Nusatidia Deeleman-Reinhold, 2001 and Matidia Thorell, 1878 in having the similar, long slender body and legs ( Figs 1 , 10, 11 ), but can be distinguished from Nusatidia by the relatively large eyes ( Fig. 1 ) and from Matidia by the higher cephalic region /carapace width ratio (approximately 2/3, while 1/ 2 in Matidia ), femur I shorter than femur II and, cheliceral promarginal teeth inserted farther from base of fang than retromarginal ones ( Fig. 9 ). Pristidia species also can be recognized by the following combination of genitalic characters: embolus with a claw-like apex; cymbial base with a blunt flange ( Figs 3–8 , 12–14 ; Deeleman-Reinhold 2001: figs 185, 194, 200); epigynal plate round, disc-shaped, posterior margin heavily sclerotized, insemination ducts visible through semitranslucent anterior region ( Fig. 15 ; Deeleman-Reinhold 2001: figs 187, 191, 195).

Distribution. South East Asia ( Thailand, Malaysia, Sumatra, Java and Borneo) and China (Hainan, Jiangxi, Taiwan, Guizhou).

Composition. Two species-groups comprising six species: Pristidia prima group ( P. longistila Deeleman- Reinhold, 2001, P. prima Deeleman-Reinhold, 2001 , P. ramosa Yu, Sun & Zhang, 2012 , P. secunda Deeleman- Reinhold, 2001 and Pristidia cervicornuta sp. nov.) and P. viridissima group ( P. viridissima Deeleman-Reinhold, 2001 ).
