Type material. Male holotype from Quebrada Palo Blanco (4°43′40.08″N; 75°34′48.36″W), 1900m, Santuario de Fauna & Flora Otún Quimbaya, Vereda La Suiza, Corregimiento La Florida, Risaralda, Colombia, II-IV.2005, A. Sabogal leg. (ICN-Ar-10615). Paratypes: one female with same data (ICN-Ar-10631) GoogleMaps .

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 View FIGURE 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 View FIGURE 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 View FIGURE 15 F–G).

Description. Male (Holotype, ICN-Ar-10615). Carapace brownish, darker on the cephalic region ( Fig. 15A View FIGURE 15 ). Chelicerae dark brown. Labium and endites brown. Sternum yellow, darkest anteriorly. Legs brownish, metatarsus and tarsus darker. Abdomen yellow ( Fig. 15A View FIGURE 15 ). Spinnerets yellow. Total length 8.76, carapace length 3.51, width 2.83, high 0.93. Clypeus height 0.2. Eye diameters and interdistances: AME 0.10, ALE 0.15, PME 0.21, PLE 0.21; AME–AME 0.29, AME–ALE 0.4, PME–PME 0.54, PME–PLE 0.49, ALE–PLE 0.46.

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 ( Fig. 15 View FIGURE 15 C–E).

Female (Paratype, ICN–Ar 10631). Carapace pale brownish, with patches of dark brown setae along midline, ocular area darkest ( Fig. 15B View FIGURE 15 ). Chelicerae brownish. Labium and endites brownish. Sternum yellow, margin darker, anteriorly lightest. Legs yellow basally, becoming brownish with some brown spots from distal side of femora to the patellae, from tibiae to tarsi yellow with some brown strips. Abdomen dorsally yellow with some patches of dark brown setae ( Fig. 15B View FIGURE 15 ); ventrally yellow with some gray spots. Spinnerets yellow ( Fig. 7B View FIGURE 7 ). Total length 7.95, carapace length 2.71, width 2.36, high 1.08. Clypeus height 0.11. Eye diameters and interdistances:AME 0.09, ALE 0.14, PME 0.17, PLE 0.19; AME–AME 0.26, AME–ALE 0.29, PME–PME 0.42, PME–PLE 0.42, ALE–PLE 0.39.

Abdomen: length 5.13, epigastric furrow 1.2 from tracheal spiracle, spiracle 2.57 from base of spinnerets. Epigynum: hood triangular; lateral borders weakly sclerotized, thin, semicircular; atrium not delimited by the lateral borders; internally with short, sinuousus copulatory ducts; seminal receptacles small, inserted on the anterior third of the copulatory ducts, spermathecae small, slender, with an anterior extension and posteriorly positioned; fertilization ducts shorter than spermathecae ( Fig. 15 View FIGURE 15 F–G).
