“…He suggested that the loss of dimorphic chelicerae (their character 3) and the dorso‐basal apophyses on male femur IV (their character 4) should be considered synapomorphies for Gonyleptidae, which is concept included Metasarcinae as sister of all members of the family. However, members of Metasarcinae do not share these apomorphic traits (Benedetti, ; and see Figs. S4 and S6).…”

“…Later, some gonyleptid subfamilies were transferred to three families, namely Cranaidae, Manaosbiidae, and Stygnidae (Sørensen, ; Kury, , ), and new ones were erected (e.g. Cobaniinae Kury, ; Gonyassamiinae Soares and Soares, 1984; Heteropachylinae Kury, ; Metasarcinae Kury, ; Pachylospeleinae Šilhavý, 1974; Progonyleptoidellinae Soares and Soares, ; Sodreaninae Soares and Soares, ; Ampycinae Kury, ). Finally, after Tricommatidae was down‐ranked to a subfamily of Gonyleptidae (Kury, ), 16 subfamilies are recognized.…”

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.

“…Como grupo externo foram selecionados espécies com revisões taxonômicas recentes Benedetti, 2012) (Yamaguti & Pinto-da-Rocha, 2009), a família Metasarcidae foi selecionada por ser considerada como grupo irmão de Cosmetidae, já a família Gonyleptidae foi utilizada para o enraizamento da análise por ser um grupo distante da família em questão.…”

Phylogenetic relationships in Opiliones (Arachnida) at the suborder level have greatly stabilized in recent years, largely due to advances in molecular systematics. Nonetheless, identifying morphological characters in the context of well-resolved phylogenies is essential for testing new systematic hypotheses and establishing diagnostic markers. Here, we investigate with SEM a promising character system across Opiliones: the sensilla on the distalmost article of legs I and II. We identified four discrete characters and scored species of nearly all families of Laniatores (28 families, 44 species), three Dyspnoi, two Eupnoi and two Cyphophthalmi. Using a phylogenetic backbone compiled from recent and ongoing phylogenomic studies, we trace the evolution of these sensilla using ancestral state reconstruction. We discover a widespread occurrence of three sensilla (a pair of sensilla basiconica and one hooded sensillum) on the anterior legs of all families of Laniatores studied, and that comparable structures occur in the other suborders of Opiliones. Our analysis shows that this sensory field provides diagnostic information at different levels of phylogenetic relationships. We discuss the implications of the widespread occurrence of these sensilla in Opiliones, which have recently been hypothesized as hygro-/thermoreceptors and their putative homology with tarsal organs in Arachnida.
