Gracilentus gen. nov. (dzƦø)

Type species: Gracilentus denticulatus sp. nov.. (ØdzdzƦ)

Etymology. The genus name comes from the Latin adjective “ Gracilentus ”, meaning “simple”, referring to the simple paracymbium in the male palp. Gender is masculine.

Diagnosis. Gracilentus gen. nov. can be distinguished from any other Erigoninae genus by the embolic division with broad round radix, anterior margin with a tongueshaped projection, giving rise to stout embolus covered by the convector, embolus hidden on unexpanded palp ( Fig. 120A, C , 121A–C ). Epigyne with ventral plate longer than wide, protruding above the epigastric furrow posteriorly, posterior margin irregular. Copulatory ducts extending above or behind the spermathecae anteriorly with or without fused loop ( Fig. 122A–C ).
