“…We analysed 773 records of 123 harvestman species of the suborder Laniatores, which are endemic to the Atlantic Rain Forest and belong to the following recently reviewed taxonomic groups: gonyleptids in the subfamilies Caelopyginae (Pinto‐da‐Rocha, ), Goniosomatinae (DaSilva and Gnaspini, ), Heteropachylinae (Mendes, ), Bourguyiinae (Yamaguti and Pinto‐da‐Rocha, ), Hernandariinae (DaSilva and Pinto‐da‐Rocha, ), Progonyleptoidellinae (Kury, ) and Sodreaninae (Pinto‐da‐Rocha and Bragagnolo, ); Stygnidae genus Pickeliana (Hara and Pinto‐da‐Rocha, ); Escadabiidae; Zalmoxidae; and Kimulidae (see species list in Supporting Information, Table S2).

A protocol for the delimitation of areas of endemism and the historical regionalization of the Brazilian Atlantic Rain Forest using harvestmen distribution data

The concept of areas of endemism (AoEs) has rarely been discussed in the literature, even though the use of methods to ascertain them has recently increased. We introduce a grid-based protocol for delimiting AoEs using alternative criteria for the recognition of AoEs that are empirically tested with harvestmen species distributions in the Atlantic Rain Forest. Our data, comprising 778 records of 123 species, were analysed using parsimony analysis of endemicity and endemicity analysis on four different grids (two cell sizes and two cell placements). Additionally, we employed six qualitative combined criteria for the delimitation of AoEs and applied them to the results of the numerical analyses in a new protocol to objectively delimit AoEs. Twelve AoEs (the most detailed delimitation of the Atlantic Rain Forest so far) were delimited, partially corroborating the main divisions previously established in the literature. The results obtained with the grid-based methods were contradictory and were plagued by artefacts, probably due to the existence of different endemism patterns in one cell or to a biogeographical barrier set obliquely to latitudinal and longitudinal axes, for example. Consequently, the congruence patterns found by them should not be considered alone; qualitative characteristics of species and clade distributions and abiotic factors should be evaluated together. Mountain slopes are the main regions of endemism, and large river valleys are the main divisions. Refuges, marine transgressions and tectonic activity seem to have played an important role in the evolution of the Atlantic Rain Forest.

“…Some examples of cases of sympatry in the family are known from the genus Eutimesius, which was observed by the first author from cloudy forest in Yaracuy state in Venezuela (Osvaldo Villarreal, unpubl. data) and two species of Pickeliana coexisting from Bahia state in Brazil (Hara & Pinto-da-Rocha, 2008). Preference for microhabitat seems to have been detected in both Eutimesius species studied here.…”

We herein propose the transfer of Metaphareus punctatus Roewer, 1913, to the genus Eutimesius Roewer, 1913 (Heterostygninae) based on the genital morphology of the species and morphology of tarsi III and IV, resulting in the new combination Eutimesius punctatus (Roewer, 1913), comb. nov. New geographical records for E. albicinctus (Roewer, 1915) are offered, recording sympatry between the congeneric species E. albicinctus and E. punctatus and data on the reproductive behavior of E. punctatus are presented, suggesting the existence of parental care in this species.

For the first time a hypothesis of homology is proposed for the macrosetae which compose the armature of the distal truncus penis of the Gonyleptoidea. Previous attempts to name them in the literature have not been continued because they started by referring to macrosetae based on their position, which may change widely, and all of them were very narrow in scope. The present project instead names groups of macrosetae that do not mandatorily refer to their position, thus compensating for their hypothesized secondary position shifts. Using criteria of topology, shape and exclusion, six groups of setae are recognized, A–E, and their topological and phylogenetic distribution is studied and described in all families of Gonyleptoidea and two other related families of Grassatores. A cladistic analysis is performed, providing the following results: (1) the Microsetata are recovered including Metasarcidae/Cosmetidae sister to an expanded Gonyleptidae; (2) the genera Quindina (Cranaidae) and Zygopachylus (Manaosbiidae) are transferred to Nomoclastidae rank nov., hitherto regarded as a subfamily of Stygnidae, now a sister group of the Microsetata; (3) Zamorinae, currently placed in Cranaidae, is the sister group to Nomoclastidae, and it is therefore transferred to this family; (4) an expanded Gonyleptidae is recovered, including Manaosbiidae and Cranaidae, but the independence of these families is also recovered because the Gonyleptidae stricto sensu form a clade; (5) the Ampycinae, in spite of many particularities, are recovered inside Gonyleptidae; (6) the zamorine‐less Cranaidae are recovered as a monophyletic sister group to Gonyleptidae, but not nested inside it. Jabbastygnus gen. nov. is described in Stygnidae along with its type species J. huttorum, from Colombia. © 2015 The Linnean Society of London
