Patrera anchicaya new species

Figures 4A–G; 31

Type material. Male from Centro Anchicayá (3°32′0″N; 76°52′3″W), 680m, Rio Anchicayá, Valle del Cauca, Cali, Colombia, no data, W. Eberhard leg. (MCZ). Paratypes: female same data as holotype (MCZ).

Etymology. The specific epithet is a noun in apposition taken from type locality at the River Anchicayá.

Diagnosis. Males of Patrera anchicaya n. sp., resemble those of P. fulvastra by their elongated cymbium, prominent, strong subtegular projection and embolus with modified base and filiform the rest of its extension (see Brescovit 1997: 146 figs 46–50), but can be distinguished by having a additional projection (no denticles) on anterior side of the embolus base, a small and conical dorsal projection on palpal tibia, and short and wide retrolateral tibial apophysis (longer and thinner in P. fulvastra) (Fig. 4 C–E). Females resemble those of P. fulvastra, by their anteriorly elongated hood and posteromedially situated spermathecae (Brescovit 1997: 146–147, figs 51–52), but can be distinguished by thinner atrium and thinner lateral borders, extending to anterior region of the hood (wider in P. fulvastra), and larger spermathecae (smaller in P. fulvastra) (Fig. 4 F–G).
