Diagnosis

The female has a somewhat similar epigyne to that in Menemerus carlini ( Peckham & Peckham, 1903) , both species have very large atria forming deep ‘bowls’. Menemerus niangbo sp. nov. differs in having a double epigynal pocket (single in M. carlini ) and bean-shaped spermathecae (spherical in the second species).

Etymology

The specific name is a noun in apposition, deriving from the name of the type locality.
