Chorizopes longus sp. n. Figs 13-14, 15-16, 17-20, 21-24

Etymology.

The specific name comes from the Latin longus , meaning long, referring to the long median apophysis; adjective.

Diagnosis.

The new species can be separated from all known congeneric species by: the median apophysis extremely long, more than 2/5 portions beyond the edge of the genital bulb in prolateral view (Figs 17-18, 21-22), and having a spur near the base (arrowed in Figs 17, 21); the copulatory ducts long and attaching the spermathecae at the anterior ventral surface (Figs 19-20, 23-24).
