“…We sampled four very distinct species from morphological, ecological and behavioural perspectives. Our results corroborate the hypothesis of DaSilva and Pinto‐da‐Rocha () that shows Gonyleptinae as a polyphyletic group. In a recent paper, Werneck et al.…”

“…Although some previous studies mapped reproductive (Machado and Raimundo, ; Machado et al., ; Nazareth and Machado, ) and defensive behaviours (Hara and Gnaspini, ; Hara et al., ) on phylogenies, behavioural and ecological characters are virtually absent from the data matrices of all harvestman groups. Two exceptions are provided by Kury (), who defined one ecological character related to habitat use in the phylogeny of Mitobatinae; and by DaSilva and Pinto‐da‐Rocha (), who included the character “camouflage with debris” in the phylogeny of Hernandariinae. In addition to the difficulty of acquiring behavioural data for a large number of species, other issues, such as the difficulty of defining behavioural homologies and the supposed plasticity of behavioural characters, are frequently used as reasons to not employ behavioural and ecological data in phylogenetic analyses (see discussion in Proctor, ).…”

The large Neotropical family Gonyleptidae comprises nearly 820 species divided into 16 subfamilies. The majority of publications on harvestman ecology, behaviour and scent gland secretion chemistry have focused on this family. We used the information available in the literature and combined it with an intensive search for ecological, behavioural and chemical data to infer the phylogeny of the Gonyleptidae. We included 28 species belonging to 14 of the 16 gonyleptid subfamilies in the ingroup and four species belonging to the families Cosmetidae, Stygnidae and Manaosbiidae in the outgroup. We performed the analyses using equally weighted characters and coded 63 characters comprising 153 states, which makes this the largest non‐morphological, non‐molecular phylogenetic data matrix published to date. We obtained five most parsimonious trees, and the strict consensus resulted in six collapsed nodes. The results show that the monophyly of Gonyleptidae is equivocal because Metasarcinae is placed at a basal polytomy with the outgroups Cosmetidae and Stygnidae. Gonyleptinae, Pachylinae and Progonyleptoidellinae are polyphyletic groups, but the remaining subfamilies are monophyletic and have several synapomorphies. Based on the resulting topology, we discuss the performance of ecological, behavioural and chemical characters, and map a selected set of characters to discuss their evolutionary patterns in the family.

“…Within this modern framework, the systematics of many groups has been addressed by incorporating phylogenetic methods and an unprecedented set of characters upon which taxonomic actions were based. Examples of such an approach can be found in Mitobatinae (Kury, ; Bragagnolo and Pinto‐da‐Rocha, ), Caelopyginae (Pinto‐da‐Rocha, ), Bourguyiinae (Yamaguti and Pinto‐da‐Rocha, ), Goniosomatinae (DaSilva and Gnaspini, ), Hernandariinae (DaSilva and Pinto‐da‐Rocha, ), Sodreaninae (Pinto‐da‐Rocha and Bragagnolo, ), and Heteropachylinae (Mendes, ).…”

Gonyleptidae is the second most diverse harvestmen family and the most studied in terms of morphology, behaviour, and ecology. Despite this, few phylogenetic studies have focused on gonyleptids, and those are based on a very limited number of taxa. We addressed this gap by constructing a phylogenetic hypothesis of the family using 101 taxa from all 16 gonyleptid subfamilies and four mitochondrial and nuclear loci (COI, 28S rRNA, 12S rRNA, and 16S rRNA). These were analysed under parsimony and likelihood optimality criteria (and using direct optimization for the former). Relationships among Gonyleptoidea and within each subfamily of Gonyleptidae were largely congruent between parsimony and maximum‐likelihood approaches. Taxonomic actions from our phylogeny include the following: Tricommatidae, new status, is restored as a family; Metasarcidae, new status, is recognized as a family and considered sister to the Cosmetidae; and Cranainae and Manaosbiinae are suggested as members of Gonyleptidae, restoring Roewer's concept of the family. Within Gonyleptidae, the “K92” group—composed of Sodreaninae, Caelopyginae, Hernandariinae, Progonyleptoidellinae, and Gonyleptinae—forms a clade, although the latter two subfamilies are not monophyletic. The genus Parampheres is here transferred to Caelopyginae, and “Multumbo” dimorphicus to Gonyleptinae. Gonyleptidae is characterized by the presence of a ventral process on the penis glans and a bifid apophysis on the male coxa IV. The long‐legged Mitobatinae can be considered monophyletic only if some short‐legged pachylines are included, or if we assume that elongate legs arose twice independently (in the true mitobatine genera and in Longiperna). Pachylinae, the most diverse gonyleptid subfamily, represents several distinct lineages. We further conclude that the traditional use of a small set of morphological characters in the systematics of Gonyleptidae is unable to explain the complex evolution of the family.

“…Pachylinae is the largest subfamily in Gonyleptidae, with 129 genera and 400 described species . The subfamily is considered polyphyletic, based on morphological (Pintoda-rocha, 2002;da Silva & Pinto-da-rocha, 2010;MendeS, 2011;Bragagnolo & Pinto-da-rocha, 2012;hara et al, 2012), phenotypic (caetano & Machado, 2013) and molecular data (Pinto-da-rocha et al, 2014).…”

A taxonomic review of the genus Neopachylus Roewer, 1913 together with keys to the species for both males and females are presented. Gephyropachylus marginatus Mello-Leitão, 1931 is considered a junior subjective synonym of Neopachylus serrinha Soares & Soares, 1947, and Huralvius incertus Mello-Leitão, 1935 is considered a synonym of Neopachylus nebulosus (Mello-Leitão, 1936). This genus is restricted to southern Brazil, occurring in states of Paraná, Santa Catarina and Rio Grande do Sul.
