03E6B3090754FFB4FF45C8FAEB153C99.taxon	discussion	Remarks. Kury et al. (2010), in an expedition to State of Tocantins for the Project “ Aracnídeos e Miriápodes da Mata Atlântica ” (AMMA) collected several individuals of Stygnidae, identified as Protimesius evelinae Soares & Soares. I have reviewed this material and was able to confirm the misidentification. The specimens are herein designated as paratypes. Types data: Brazil, Tocantins state, Lajeado (UHE Luis Eduardo Magalhães), IV. 2002, D. Pavan leg. 3 holotype (MZSP 30253); idem, Porto Nacional, (Luzimangue), 13. IV. 2007, A. Kury et al. leg.

The specific name means “ gift ” in Italian and refers to Ricardo Pinto-da-Rocha, who kindly offered me the opportunity to study the specimens herein designated as holotype.	en	Bragagnolo, Cibele (2013): Two new species of Protimesius from northern Brazil (Opiliones: Laniatores: Stygnidae).

03E6B3090754FFB4FF45C8FAEB153C99.taxon	diagnosis	Diagnosis: The new species differs from the other species of the genus by the presence of a dorso apical tubercle on fermur IV. It is is similar to P. evelineae Soares & Soares and P. foliadereis Villarreal-Manzanilla & Pinto-da-Rocha, due to the presence of a dorsal and an apical retrolateral row of acute tubercles on male tibia IV. It differs from these species due to the absence of a ventral row of tubercles on male tibia IV, and the presence of two dorsal rows of tubercles on male patella IV.	en	Bragagnolo, Cibele (2013): Two new species of Protimesius from northern Brazil (Opiliones: Laniatores: Stygnidae).

Fig. 5 shows an aggregation of Protimesius regalo sp. nov. found under the litter death leaf (Pérez- Gonzáléz, pers. com.), in Porto Nacional, State of Tocantins, Brazil. As recorded for other arthropods (Rasa 1997), harvestmen aggregations are more commonly found during dry and cold periods or in xeric environments, such as Tocantins (central western-Brazil). In this environment, the gregarious habit could have a very important adaptive value, likely reducing evaporation among grouped individuals. Moreover, harvestmen aggregations are generally more frequently found during the day (Machado & Macías-Ordóñez 2007). Likewise, the individuals of Protimesius regalo sp. nov. were aggregated under the litter during the day, and during the night they dispersed for foraging. This behavior was observed also in captivity (A. Pérez-González pers. comm.). For Laniatores, the records of aggregations are restricted to cavities in the ground or tree trunks, inside the caves or under the rocks (see table 11.1 in Machado & Macías-Ordóñez 2007). The only other record of aggregation in Stygnidae is from Protimesius longipalpis (Roewer, 1943) found inside cavities of tree trunks (Machado & Macías-Ordóñez 2007). Thus, this is the second record of aggregation for Stygnidae and, among the Laniatores, the first record found in forest litter.	en	Bragagnolo, Cibele (2013): Two new species of Protimesius from northern Brazil (Opiliones: Laniatores: Stygnidae).

03E6B3090752FFB7FF45C9F8E8EC3E91.taxon	diagnosis	Diagnosis: This species is similar to P. c ir io Villareal-Manzanilla & Pinto-da-Rocha and P. laevis (Sorensen, 1932) by the presence of a large, pointed, dorso-apical apophysis on male trochanter IV. It differs from the others species of Protimesius due to the absence of a ventral row of tubercles on male femur IV — present in all species of the genus except P. longipalpis and P. a p i a c a s — and the presence of a ventrobasal curved apophysis on femur IV.	en	Bragagnolo, Cibele (2013): Two new species of Protimesius from northern Brazil (Opiliones: Laniatores: Stygnidae).
