Type species: Absconditus acerus sp. nov. (KḰĎẌƦ)

Diagnosis. Absconditus gen. nov. can be distinguished from any other Erigoninae genera by distal suprategular apophysis robust with a projection extending posteriorly, radix relatively small, round and almost hidden in the distal tegular apophysis in undisected palp ( Figs 1A–C , 2A–G ). Epigynal palte wider than long, with a median septum narrowing posteriorly ( Fig. 3A, B ), copulatory openings present anteriorly beneath the septum ( Fig. 3A, B ). Copulatory ducts S-shaped, spermathecae pointing towards dorso-mesally ( Fig. 3C ).
