Genus Parvattus gen. nov.

Type species: Parvattus zhui Zhang & Maddison , sp. nov.

Etymology. The generic name is from the combination of parvus (small) and attus (a common ending for salticid genera), referring to the extremely small embolic division of the male palp; masculine in gender.

Diagnosis. Small leaf litter dwelling jumping spiders. Male chelicera with two promarginal teeth and one retromarginal tooth ( Fig. 78 ). Male palpal bulb large; embolic division very small with embolus short and wide; retrolateral sperm duct loop wide; proximal tegular lobe and ventral tibial bump present; retrolateral tibial apophysis finger-like ( Figs 79–80 ). Differs from other leaf litter dwelling euophryine genera by the peculiar shape of the embolic division of the male palp ( Fig. 79 ).
