3E2BA11B560AFFBA0492FD5BE565FDE0.taxon	description	The general habitus of Eusarcus minutus comb. nov. (Fig. 1 A) resembles closely most species in the genus. The main shared features include the three well-developed paracheliceral frontal apophyses, the shape and curvature of the prolateral apophysis on coxa IV of males, the triangular, short, blunt prolateral apophysis on the male trochanter IV, and male femur IV with prolateral and retrolateral rows of apophyses and two distinct ventroapical ones (Hara & Pinto-da-Rocha 2010). Unlike most Eusarcus species, which typically bear a median conic apophysis on the scutal area III, E. minutus lacks any armature on the scutum, a feature shared with a few other species, like e. g. E. sergipanus Hara & Pinto-da-Rocha, 2010, E. gemignanii (Mello-Leitão, 1931) and E. uruguayensis (Ringuelet, 1955). In addition, the ocular mound of E. minutus is armed by a single apophysis (Fig. 1 A), instead of the paired armature most frequent in genus Eusarcus (Hara & Pinto-da-Rocha 2010). The referred character states were used by Ringuelet (1959) to separate Pucrolia from Eusarcus. The tarsal formula 5 - 6 - 6 - 6 of the nominal genus Pucrolia (of little help) is shared with E. gemignanii, E. grumani H. Soares, 1966 and E. uruguayensis. Finally, the male genitalia of Eusarcus minutus (Fig. 1 B – C) consistently match the descriptions of those of most Eusarcus species (cf. Hara & Pinto-da-Rocha 2010).	en	Acosta, Luis E., Guerrero, Elián L. (2021): The missing Eusarcus: generic relocation of Pucrolia minuta, with synonymic notes (Opiliones: Laniatores: Gonyleptidae).

3E2BA11B560AFFBA0492FD5BE565FDE0.taxon	description	As for the largely questioned Pucrolia gracilipes, it is to be considered a junior synonym of E. minutus. The type material of the former is presumably lost (Guariento et al. 2018), but drawings and description given by Canestrini (1888: 107, Pl. 9, figs. 4, 4 a-d) clearly show a female E. minutus. The type locality of P. gracilipes (Resistencia, Chaco province, Argentina) is placed in middle of the geographic range of E. minutus (cf. Ringuelet 1959).	en	Acosta, Luis E., Guerrero, Elián L.

3E2BA11B5609FFBA0492FD55E39EFA41.taxon	description	Pucrolia grandis is the largest member of Pucrolia (“ mais do dobro das outras duas especies ”, Mello-Leitão 1930: 213), and was diagnosed by a very infrequent feature: the single apophysis on the ocular mound is curved backwards (Ringuelet 1959: fig. 53 a). This species is only known by its holotype, a female from (allegedly) Buenos Aires (Ringuelet 1959). Mello-Leitão (1930) placed this species in Pucrolia just by using characters based upon the Roewerian system, including: ocularium armed with a single apophysis; dorsal scutum, free tergites and anal operculum unarmed; palpal femur with a sub-apical mesal spine; and tarsal formula 5 - 6 - 6 - 6. Nonetheless, this combination is not exclusive to Pucrolia, as these traits can be observed in females of other taxa, e. g., Pachyloidellus Müller, 1918 and Acanthopachylus Roewer, 1913. A side-by-side comparison demonstrated that the type of P. grandis is a female Pachyloidellus butleri (Thorell, 1877), considering the subtle armature of leg IV, especially the retroapical apophysis (Ringuelet 1959: fig. 53 b-c), and shape and granulation of the dorsal scutum (Acosta 1993). The only difference is the armature of the ocularium, with P. butleri having a straight apophysis, slightly inclined frontwards, instead of bent backwards as in P. grandis. The curved apophysis seems a striking feature not found in other species of Pucrolia or Eusarcus, but the condition on the holotype is most likely an individual abnormality. Based upon all of the evidence, we propose the new synonymy. Brazilian species: Pucrolia dubitata and P. pulcherrima show no special resemblance with Eusarcus. Despite being little studied (the former is only known by a single female, and the genital morphology is unknown for both), for the moment they should be referred to as incertae sedis.	en	Acosta, Luis E., Guerrero, Elián L.
