“…Our resolution inside Aphantochilinae is slightly different from the one obtained by Teixeira et al.

Of the thomisids retaining several cheliceral teeth (“stephanopines”), we obtain a lengthy multinode grade separated by branches with weak support.…”

We present a phylogenetic analysis of spiders using a dataset of 932 spider species, representing 115 families (only the family Synaphridae is unrepresented), 700 known genera, and additional representatives of 26 unidentified or undescribed genera. Eleven genera of the orders Amblypygi, Palpigradi, Schizomida and Uropygi are included as outgroups. The dataset includes six markers from the mitochondrial (12S, 16S, COI) and nuclear (histone H3, 18S, 28S) genomes, and was analysed by multiple methods, including constrained analyses using a highly supported backbone tree from transcriptomic data. We recover most of the higher‐level structure of the spider tree with good support, including Mesothelae, Opisthothelae, Mygalomorphae and Araneomorphae. Several of our analyses recover Hypochilidae and Filistatidae as sister groups, as suggested by previous transcriptomic analyses. The Synspermiata are robustly supported, and the families Trogloraptoridae and Caponiidae are found as sister to the Dysderoidea. Our results support the Lost Tracheae clade, including Pholcidae, Tetrablemmidae, Diguetidae, Plectreuridae and the family Pacullidae (restored status) separate from Tetrablemmidae. The Scytodoidea include Ochyroceratidae along with Sicariidae, Scytodidae, Drymusidae and Periegopidae; our results are inconclusive about the separation of these last two families. We did not recover monophyletic Austrochiloidea and Leptonetidae, but our data suggest that both groups are more closely related to the Cylindrical Gland Spigot clade rather than to Synspermiata. Palpimanoidea is not recovered by our analyses, but also not strongly contradicted. We find support for Entelegynae and Oecobioidea (Oecobiidae plus Hersiliidae), and ambiguous placement of cribellate orb‐weavers, compatible with their non‐monophyly. Nicodamoidea (Nicodamidae plus Megadictynidae) and Araneoidea composition and relationships are consistent with recent analyses. We did not obtain resolution for the titanoecoids (Titanoecidae and Phyxelididae), but the Retrolateral Tibial Apophysis clade is well supported. Penestomidae, and probably Homalonychidae, are part of Zodarioidea, although the latter family was set apart by recent transcriptomic analyses. Our data support a large group that we call the marronoid clade (including the families Amaurobiidae, Desidae, Dictynidae, Hahniidae, Stiphidiidae, Agelenidae and Toxopidae). The circumscription of most marronoid families is redefined here. Amaurobiidae include the Amaurobiinae and provisionally Macrobuninae. We transfer Malenellinae (Malenella, from Anyphaenidae), Chummidae (Chumma) (new syn.) and Tasmarubriinae (Tasmarubrius, Tasmabrochus and Teeatta, from Amphinectidae) to Macrobuninae. Cybaeidae are redefined to include Calymmaria, Cryphoeca, Ethobuella and Willisius (transferred from Hahniidae), and Blabomma and Yorima (transferred from Dictynidae). Cycloctenidae are redefined to include Orepukia (transferred from Agelenidae) and Pakeha and Paravoca (transferred from Amaurobiidae). Desidae are rede...

“…Here, we apply the Spatial Analysis of Vicariance (SAV) method (Arias et al 2011) to identify possible disjunctions between sister-taxa in Delphininae and related taxa, using the phylogeny of McGowen et al (2009) and an extensive geographic distributional data. SAV has been used in biogeographical analysis of terrestrial organisms (Gaetano and Rougier 2012;Latinne et al 2012;Molineri and Salles 2013;Teixeira et al 2014), but this is the first attempt to apply the method to marine cetaceans. We seek to test SAV for a setting (the oceans) which generally lacks hard barriers, and a wide-ranging study taxon -Cetacea -which has high dispersal capabilities compared with organisms in terrestrial biomes.…”

Delphinine dolphins arose via a recent, rapid radiation, probably within the last four million years. Although molecular phylogenies are increasingly well resolved, patterns of morphology-ecology-geography are hard to link to phylogeny or to translate into taxonomy. Such problems might be tackled through understanding the drivers of the delphinine radiation. Here, we examine delphinine historical biogeography using the phylogeny of McGowen et al. 2009 as our working hypothesis. We used the "Spatial Analysis of Vicariance" method to delimit modern distribution patterns, including disjunctions involving sister nodes in the Delphininae. The analysis identified disjunct sister nodes, allowing some interpretation of Delphininae biogeography. The Central American Seaway was probably an important gateway for early delphinids, but the succeeding "hard" barrier of the Panama Isthmus had little influence. Southern African waters form the Atlantic-Indo-Pacific gateway, which is sometimes considered a "soft" barrier because of the variation in the Benguela and Agulhas currents, in turn driven by tectonic changes and/or Pleistocene glacial and interglacial cycles. The latter cycles probably fragmented coastal habitats, allowing allopatric speciation. Geological patterns of turnover in Southern Ocean diatoms, which link to physical oceanic change, closely match the main cluster of delphinine divergences. The Eastern Pacific Barrier, and perhaps the associated Humboldt Current and equatorial "cold tongue", affect modern distributions, but cause and effect are poorly understood. Future research should involve molecular-morphological phylogenetics for all species, subspecies, and ecomorphs.Complete distributions must be known for all taxa to understand how vicariance and dispersal shaped the distribution of delphinines.

“…This species lacks the typical cheliceral teeth that are still considered as a diagnostic feature for Stephanopinae. Instead, its elongated labium and peglike-setae on endites (see Teixeira et al 2014) allow us to undoubtedly consider this spider as an Aphantochilinae. We propose the transfer of S. quimiliensis to Ulocymus Simon, 1866 based on the presence of stout and conical projections on the dorsum of the carapace (see Teixeira et al 2014) and shape of the copulatory structures (Fig.…”

A recent phylogenetic analysis has shown that the genus Stephanopis comprises several different lineages of bark-dweller crab spiders. The ones with South American distribution that present a close relationship with other Neotropical genera like Epicadus, Onocolus, Rejanellus and Epicadinus were recovered in a single clade, with good support and stability. Here, we present a taxonomic review of Stephanopis species attributed to the ‘pentacantha clade’, proposing the new genus Kryptochroma Machado gen. nov. to accommodate them. New distribution records are provided and the following species are described for the first time: Kryptochroma gigas Machado & Viecelli gen. et sp. nov., Kryptochroma hilaris Machado & Teixeira gen. et sp. nov., Kryptochroma quadrata Machado & Viecelli sp. nov. and Kryptochroma septata Machado & Teixeira sp. nov. The species Stephanopis borgmeyeri is considered a nomen dubium, Stephanopis aheneus is a junior synonym of Epicadus tuberculatus, Stephanopis quimiliensis is transferred to Ulocymus and Stephanopis stelloides is transferred to Epicadus, being Epicadus stelloides the senior synonym of Stephanopis salobrensis, Stephanopis trilobata and Epicadus caudatus.
