Etymology.

The specific name refers to Atlach-Nacha, a supernatural entity from Cthulhu mythology that resembles a huge spider with an almost human face.

Diagnosis.

Ochyrocera atlachnacha resembles O. varys by its carapace yellow and bright lime (Figs 1 A–B, 4 A–B) and palp with conical, elongated and distal cuspule in the cymbial apophysis (Figs 1 C–D, 4 C–D). It can be distinguished from the latter and other Neotropical species by the male palpal cymbium with accentuated cymbial prolateral projection (Figs 4D, 5C, E–F); females have enlarged and projected pore-plates on the inconspicuous spermathecae (Fig. 4 E–F).

Clypeus length 0.7, with a pair of long bristles (Fig. 4A). Eyes: PME oval; ALE and PLE rounded. Chelicerae light yellow; promargin with 6 teeth, attached to a very long lamina (Fig. 5A); retromargin without teeth. Sternum light gray to darker. Endites dark yellow to green.

Abdomen length 1.3, oval; uniformly grayish-green. Six epiandrous spigots, with short base (Fig. 5B)

Female (paratype IBSP 188899). Total length: 2.0; carapace length: 0.74; Carapace as in male, light yellow pattern (Fig. 4B).
