description: Goeldia patellaris (Simon, 1892)
(Figs 19; 27)
Amaurobius patellaris Simon, 1892: 434, pl. 9, fig. 8 (syntypes 2♂ and 18♀ from Venezuela (10°30’00”N 66°56’00”W), MNHN 293, examined).
Amaurobius arnozoi Mello-Leitão, 1924: 276 (holotype ♀ from Alto Juruá (8°46’45”S 72°7’5”W), Acre, Brazil, deposited at MNRJ, not found, lost before fire 2018); Bonnet 1955: 275; Silva-Moreira et al. 2010: 8; World Spider Catalog 2023. Syn. nov.
Goeldia patellaris: Lehtinen 1967: 236 (erroneously placed G. patellaris as synonym to G. obscura Keyserling, 1891).
Goeldia arnozoi: Lehtinen 1967: 236.
Remarks. According to specimens examined, original description and drawing presented by Simon (1892: pl. 9, fig. 8) G. patellaris presents a patellar apophysis similar to the one found on specimens from Venezuela. Lehtinen (1967) erroneously placed a specimen from Chile as part of the syntypes series of G. patellaris and used this specimen to justify the use of G. patellaris as a replacement name to G. obscura Keyserling, 1891. We examined specimens from the type locality of G. arnozoi and concluded that this species is conspecific with G. patellaris.
Additional Material Examined. BRAZIL. Acre. Senador Guiomard, Reserva Extrativista de Catuaba (10°08'S 67°43'W), 13♂, 1♀, 2002, E.F. Morato coll. (IBSP 84577–84590). Bahia. Salvador, Bahia de Aratu (12°47’32.8”S 38°28’15.3”W), 1♂, 2007–2008, K. Benati coll. (IBSP 123564); Lagoa do Abaeté (12°56’42.36”S 38°21’25.85”W), 1♂, 2001–2003, R. Smania-Marques coll. (IBSP 64029).
Diagnosis. Goeldia patellaris differs from the other species of the genus by the long and pointed patellar apophysis (Fig. 19B–D) and tegular process with enlarged base and apex pointed and curved in the male palp (Fig. 19A‒B, D); and female epigynum with posterior edge straight (Fig. 19E) and copulatory ducts with apex retrolaterally projected (Fig. 19F).

Opisthosoma grayish black. Total length: 3.80. Carapace: length 1.80, width 1.32, height 0.95. Opisthosoma: length 2.04, width 1.24. Clypeus: height 0.14.

Tibia IV with thin, long, and straight setae. Palp with apex of the MLT partially sclerotized (Fig. 19C). Patellar apophysis apex needlelike and posteriorly projected (Fig. 19A, C–D).
Female (IBSP 84579). Coloration: following the same pattern as in male but slightly lighter. Total length: 4.35. Carapace: length 2.32, width 1.45, height 0.83. Opisthosoma: length 2.38, width 1.48.
