Kury, Adriano B., 2008, A review of Soaresia H. Soares, 1945, with the description of a new species from Serra da Mantiqueira, Brazil (Opiliones, Gonyleptidae, Pachylinae), Zootaxa 1687, pp. 51-59 : 56

Soaresia uncina H. Soares, 1945

Soaresia uncina H. Soares 1945: 244 , figs 1–2 (♂, Ψ); Soares & Soares 1954: 296; Kury 2003: 193.

Type material. HSPC 39, ɗ holotype and Ψ allotype; MZSP 813, paratype, examined: BRAZIL, Rio de Janeiro, Penedo: “Fazenda Penedo”, 700 m (-22.4200; -44.5500).

Other material examined. 6 ɗ 3 Ψ ( MNRJ 05465): BRAZIL, Rio de Janeiro, Rezende: Serrinha do Alambari, 850 m (-22.3732; -44.5387) ca. 5 km from type locality, 29–31 Dec. 1992, A. B. Kury col., leaf litter.

Etymology. From Latin unc ī nus (= a hook, barb). Probably due to the distal hooked apophysis on male femur IV. The name formation is defective, as it should be properly uncinata (“the one bearing a hook” or “hooked Soaresia ”) or uncinus (“hook Soaresia ”), but Article 32 of ICZN (1999) prevents an emendation in this case.

Diagnosis. Free tergite III with a triad of straight spines ( Fig 2 ) clearly separating this species from S. forficula , which has a pair of geminate very large hooks resembling earwig pincers. Femur IV with 2 dagger-like ventro-distal apophyses ( Fig 4 ). Patella IV of male elongate, contrasting with that of S. forficula , which is normal in size ( Fig 2 , Table 2). Tarsus II predominantly 7-jointed. Penial notch deep and truncus apex not swollen ( Figs 10–11 ). Tarsal counts (range): males (n=6) and females (n=3) 5(3)/6–8(3)/6/6. Tarsus II (variation): 6(n=1), 7(n=14), 8 (n=3). Beta males are unknown. See measurements of body and appendages in Table 2.

Female. Differences from male are, as usual in Pachylinae , the absence of armature where male presents greatly developed apophyses: free tergite III, coxa to patella IV. Color (in alcohol): Body and appendages moderate orange yellow (CC 71), mottled with deep orange yellow (CC 69). Legs II–IV shorter than in male, especially leg IV (only 80% of length, see measurements in Table 2).
