Etymology.
The specific epithet is a patronym in honor of Leonardo Carvalho, for his contributions to the taxonomy and biogeography of Neotropical pholcids.
Diagnosis.
Males of
Patrera carvalhoi
n. sp.
resemble those
P. sampedroi
n. sp.
, by having the similar cymbium shape, S-shaped, long embolus, apically bilobed retrolateral tibial apophysis, and prominent tutacular groove on the cymbium (
Fig. 19
B–D), but can be diagnosed by the retrolateral tibial apophysis very short, entire and slightly bilobed in the apex (strongly lobulated in the apex, longer and wider in
P. sampedroi
) (
Fig. 15
C–E). Females can be recognized from those of the remaining species of the genus by the copulatory ducts wide and coiled, and by the bean-shaped spermathecae (
Fig. 15
F–G).

Abdomen: length 5.21, epigastric furrow 1.21 from tracheal spiracle, spiracle 3.27 from base of spinnerets. Palp: retrolateral tibial apophysis short, small and apically bilobed; cymbium as long as half tibia length; subtegulum longer than wide, thin, with the distal projection inconspicuous; tegulum longer than wide; median apophysis long, laminar and medially situated; embolus long, apically filiform with narrow base and basally inserted on the tegulum (
