The genus Lacronia Strand, 1942 is herein revised, and a maximum parsimony phylogenetic analysis of morphological characters (30 taxa, 115 characters, 2962 scorings) is performed to test its monophyly. As a result, Lacronia is herein made monophyletic by means of the inclusion of Discocyrtus boraceae B. Soares, 1942, Discocyrtus niger Mello-Leitão, 1923 and Discocyrtus tenuis Roewer, 1917. Lacronia including those species is the sister group of Discocyrtus s. str. inside the DRMN-clade, and should be removed from Pachylinae Sørensen, 1884, although without a new subfamilial assignment for now. Four new junior subjective synonyms are detected for the first time (Discocyrtus rarus B. Soares, 1944 = Discocyrtus fazi Piza, 1942 = Discocyrtus niger Mello-Leitão, 1923; Discocyrtus infelix Mello-Leitão, 1940 = Discocyrtus nigrolineatus Mello-Leitão, 1923 = Discocyrtus tenuis Roewer, 1917). Accordingly, the following new combinations are proposed: Lacronia boraceae (B. Soares, 1942) comb. nov., Lacronia nigra (Mello-Leitão, 1923) comb. nov. and Lacronia tenuis (B. Soares, 1942) comb. nov. Lacronia is endemic to the Atlantic province of Brazil, with verified records from the states of Rio de Janeiro, Santa Catarina and São Paulo. As a geographic note, the record of ‘D. fazi’ for Chile is here discussed and considered incorrect.

The gonyleptids are one of the most diverse groups of harvestmen, exhibiting a vast range of sizes, shapes and behaviors. However, its internal classification, earlier based on meristic characters, particularly in larger groups such as Pachylinae and Discocyrtus, has been called into question by new proposals that consider morphological and molecular synapomorphies. Here, we aspire to evaluate the transfer of seven species currently classified under Discocyrtus sensu lato and the monotypic genus Oliverius from Pachylinae to Neopachylinae. Additionally, we propose the inclusion of two new species in Neopachylinae. To test our hypothesis, we expand upon previous cladistic analyses using maximum parsimony and incorporate 40 terminals representing Gonyleptoidea, including all existing members of Neopachylinae, and 116 morphological characters. Our results confirm the hypothesis of monophyly of Neopachylinae after the inclusion of the new and transferred taxa. To provide a comprehensive assessment of the results, we update some diagnoses at the genus and species-level within Neopachylinae. Furthermore, to accommodate the taxonomic changes resulting from this study, we propose 1) the establishment of two new genera, 2) the reassignment of five taxa at the generic level, and 3) the establishment of two new junior subjective synonymies at the species level.
