“…18), along the mountain range of cloud forests almost continuous between the characteristic localities of that elevation floor (Ataroff & Sarmiento, 2003). This wide local distribution contributes to deny the high endemism of the Venezuelan harvestman as González Sponga repeatedly pointed out (García et al, 2017).…”

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.

The cosmetids are conspicuous harvestmen, remarkably diverse in size, shape and colour. However, the effectiveness of all these morphological traits for diagnosing groups is scarcely explored in the literature. Since the early 20th century, the family Cosmetidae has been divided into two subfamilies, Cosmetinae and Discosomaticinae, and there has been no further effort to delimit additional or alternative subfamilial groups. In this analysis, we aim to test the issue of the basal dichotomy of Cosmetinae and Discosomaticinae. Thus, we propose a more comprehensive phylogenetic analysis using both parsimony and Bayesian approach, comprising 103 terminals of Cosmetidae, plus seven outgroup terminals scored for 130 morphological characters. Discosomaticinae is revisited and all its species were included in our matrix. To offer a real challenge to the monophyly of Discosomaticinae, members of 36 genera of Cosmetinae have also been scored. Our results support neither Cosmetinae nor Discosomaticinae sensu Pickard-Cambridge/Roewer as monophyletic groups. We found that Cosmetidae may be organized into a few major clades, which are here diagnosed. Accordingly, taxonomic changes in the arrangement of the family are introduced: description of one new tribe, five new subfamilies and revalidation of a sixth, description of three new genera, and proposition of synonymies, transfers and revalidations at generic level.
