Rhyphelia gallina sp. nov.

Figs 15A–15B, 16A–16D

Type material. Holotype: ♂ from Campus Embrapa, Rio Branco, Acre, Brazil (10.025°S, 67.693°W), VIII.2012, L.M.S. Costa leg. (UFMG 12402).

Etymology. Epithet, a Latin noun in apposition, is due to the shape of the RTA, reminiscent of a chicken wing.

Diagnosis. The male is similar to that of R. amrishi by having a smooth embolus projecting from a sclerotized distal region and reaching the tip of the cymbium (Fig. 16C). However, it differs by having an elongate RTA curved towards the center of the tegulum (Fig. 16D; short in R. amrishi, see Ruiz & Sobrinho (2016: fig. 6).
