“…As a result, most neotropical harvestmen species, such as gonyleptids, exhibit narrow and endemic ranges (DaSilva et al 2015), resulting in historically-driven distribution patterns (Nogueira et al 2019). Similar range and distributional patterns are also observed in harvestmen groups outside of the neotropics (Emata and Hedin 2016;Derkarabetian et al 2021;. Although Opiliones occurrence in arid formations is not something unheard of for some Laniatores families-e.g., representatives of Cosmetidae, Stygnidae, Phalangodidae (e.g., DiDomenico and Hedin 2016, infer Sitalcina species diversification in North America deserts)-this new genus is one of the few records for Gonyleptidae.…”

“…Currently, the description rate continues to be substantial, with many new species being cataloged and with numerous group revisions occurring (DaSilva and Gnaspini 2010;DaSilva and Pinto-da-Rocha 2010;Hara and Pinto-da-Rocha 2010;Mendes 2011;Pinto-da-Rocha and Bragagnolo 2013;Villarreal et al 2019;Carvalho and Kury 2021;Pessoa-Silva et al 2021). These high diversity rates are associated with particular traits of the order, such as a high degree of endemism, restricted distribution, dependence on humid habitats, and low resistance to desiccation, which makes populations much more prone to diversification events over time (DaSilva et al 2015;Derkarabetian et al 2021).…”

Opiliones are highly diverse in the Neotropics. Because of biological constraints, most harvestmen communities are associated with humid forests, exhibiting a high species diversity and endemism in these habitats. Drier formations, such as the Caatinga biome in northeastern Brazil, are less diverse and still considered under-sampled for the order. This study represents an effort to examine the aforementioned diversity by describing a new Gonyleptidae genus, Sertanejagen. nov., comprising two new species from Ceará state, Sertaneja bicuspidatasp. nov. and Sertaneja crassitibialissp. nov., and one new species from Rio Grande do Norte state, Sertaneja falcatasp. nov. A morphological cladistic analysis consisting of 20 terminals and 72 characters was performed to evaluate monophyly of the new genus and relate it to other Gonyleptidae. The analysis resulted in a single most parsimonious tree, corroborating Sertanejagen. nov. monophyly and relatedness to Gyndoides springmanni Soares & Soares, 1947, which in turn is the sister group to the DRMN clade. Taking into account the morphological traits and phylogenetic placement of Sertanejagen. nov., we chose to place the new genus in Pachylinae despite its polyphyletic status, given that the Sertanejagen. nov. clade is closely related to one of the Brazilian Pachylinae lineage. A resolution to the Pachylinae conundrum is needed to further explain the subfamily intricacies. Future research requires a larger scope, but currently, based on the new genus monophyly, support, and relatedness, we formally propose its creation and hope to shed light on the possible evolutionary scenarios for the subfamily.

“…After the initial separation, land bridges persisted between continental masses, providing passageways for biotic exchange 78 . Even amongst taxa with low vagility, there is mounting evidence for early Gondwanan vicariance followed by subsequent LDD events in taxa, including plants [79][80][81][82] , cave shrimp 83 , freshwater fish 84 and arachnids 85,86 . Of course, in the epochs immediately following continental breakup, the distances between major landmasses were shorter and thus dispersal among these would be more likely than among the continents in their current positions.…”

Net-casting spiders (Deinopidae) comprise a charismatic family with an enigmatic evolutionary history. There are 67 described species of deinopids, placed among three genera, Deinopis, Menneus, and Asianopis, that are distributed globally throughout the tropics and subtropics. Deinopis and Asianopis, the ogre-faced spiders, are best known for their giant light-capturing posterior median eyes (PME), whereas Menneus does not have enlarged PMEs. Molecular phylogenetic studies have revealed discordance between morphology and molecular data. We employed a character-rich ultra-conserved element (UCE) dataset and a taxon-rich cytochrome-oxidase I (COI) dataset to reconstruct a genus-level phylogeny of Deinopidae, aiming to investigate the group’s historical biogeography, and examine PME size evolution. Although the phylogenetic results support the monophyly of Menneus and the single reduction of PME size in deinopids, these data also show that Deinopis is not monophyletic. Consequently, we formally transfer 24 Deinopis species to Asianopis; the transfers comprise all of the African, Australian, South Pacific, and a subset of Central American and Mexican species. Following the divergence of Eastern and Western deinopids in the Cretaceous, Deinopis/Asianopis dispersed from Africa, through Asia and into Australia with its biogeographic history reflecting separation of Western Gondwana as well as long-distance dispersal events.

“…The family Coloburiscidae, sometimes described as the spinose-gilled mayfly family, is relatively small in comparison to other mayfly families and has only three genera: Coloburiscoides Lestage (1935), Coloburiscus Eaton (1888), and Murphyella Lestage (1930). Coloburiscoides and Coloburiscus are only found in Australia and New Zealand, respectively, while Murphyella is endemic to Chile, thus displaying a Gondwanan distribution [4,[7][8][9]. The family is not currently believed to have a presence in the remaining Gondwanan land masses, but this could be due to a comparatively decreased effort to explore mayfly taxonomy in underdeveloped countries.…”

Is Coloburiscidae (Ephemeroptera) Monophyletic? A Comparison of Datasets

Coloburiscidae consists of three living genera with a Gondwanan distribution—Coloburiscoides from Australia, Coloburiscus from New Zealand, and Murphyella from Chile. Molecular-based phylogenetic analyses of Ephemeroptera (mayflies) have been somewhat successful in resolving many higher-level relationships in the order. Most of these analyses, however, have been ambiguous with respect to the family Coloburiscidae. This study presents the first phylogenetic analysis specific to Coloburiscidae using data generated from 448 phylogenomic sequences and data generated from the Sanger sequencing of five genes: 12S, 16S, 18S, 28S, and H3. Bayesian and likelihood analyses were conducted on each dataset and, ultimately, on a combined dataset of the two. Coloburiscidae was shown to be supported as monophyletic in each instance where the phylogenomic data were included. Coloburiscoides was shown as sister to Murphyella + Coloburiscus.
