The Neotropical species of the diplurid subfamily Masteriinae are revised and redefined. Masteriinae now comprises four genera, Masteria L. Koch, 1893, Striamea Raven, 1981, a new genus, Siremata n. gen. and Edwa Raven, 2015, a fossil genus. The type species, Masteria hirsuta L. Koch, 1893, was used as basis for comparison and the knowledge of the genus has increased. Twelve species of Masteria are redescribed and eight new species are described: M. amarumayu n. sp. and M. mutum n. sp., from Brazil; M. yacambu n. sp., from Venezuela; M. sabrinae n. sp., from Martinique; M. tayrona n. sp., from Colombia; M. aguaruna n. sp., from Peru, M. soucouyant n. sp., from Trinidad and Tobago; and M. galipote n. sp., from the Dominican Republic. Females of Masteria aimeae (Alayón, 1995) and M. golovatchi Alayón, 1995 are described for the first time. Females of M. spinosa (Petrunkevitch, 1925), M. petrunkevitchi (Chickering, 1964), M. lewisi (Chickering, 1964), M. barona (Chickering, 1966), M. downeyi (Chickering, 1966), M. simla (Chickering, 1966), M. colombiensis Raven, 1981 and M. pecki Gertsch, 1982 are illustrated for the first time and rediagnosed. Masteria tovarensis (Simon, 1889) and M. cyclops (Simon, 1889) are synonymized with M. lucifuga (Simon, 1889). Masteria modesta (Simon, 1892) is considered as species inquirendae and M. emboaba Pedroso, Baptista & Bertani, 2015 is considered as incertae sedis, as the type is lost. Both species of Striamea are revised and redescribed. A new genus, Siremata n. gen., is described and includes three Amazonian species: S. valteri n. sp., S. juruti n. sp., S. lucasae n. sp. Knowledge of the distribution ranges of the Neotropical Masteriinae are increased.

The 12 species previously placed in Tortopus together with 3 species newly described here, are revised and included in a phylogenetic analysis. Based on synapomorphic characters on the nymphs and adults of both sexes, Tortopus is restricted to T. igaranus Needham & Murphy, T. circumfluus Ulmer, T. harrisi Traver, T. zottai (Navás), T. bellus Lugo-Ortiz & McCafferty, and T. arenales sp. nov., and the genus is defined by: female parastyli receptors with long furrows anterior to sockets; penes entirely flattened; male ninth abdominal sternum almost separated in two portions by a median notch; mesosternum with furcasternal protuberances contiguous only on basal corner; and nymphs with two subapical tubercles on mandibular tusks. Tortopsis is newly described for T. bruchianus (Navás), T. limoncocha sp. nov., T. obscuripennis (Domínguez), T. parishi (Banks), T. primus (McDunnough), T. puella (Pictet), T. sarae (Domínguez), T. spatula sp. nov., and T. unguiculatus (Ulmer). Tortopsis is characterized by: R sector of female fore wing without additional veins between R 2 and IR; female parastyli receptors C or V-shaped, with sockets opening towards median line; male gonopore associated with a claw-like structure; penes separated from the base; parastyli more than 5 times length of pedestals; parastyli curved in lateral view; nymphs with a single subapical tubercle on mandibular tusks. The study of available type material permitted inclusion of comparative diagnoses, with figures and redescriptions as needed. The male imago of the type species of Tortopus (T. igaranus Needham & Murphy) is described for the first time, as are the female adults of Tortopus bellus Lugo-Ortiz & McCafferty and T. harrisi Traver. Three new Neotropical species based on male and female adults are described: Tortopus arenales and Tortopsis limoncocha from Ecuador, and Tortopsis spatula from Colombia. Keys to separate the adults and nymphs of the genera of Polymitarcyidae, and for male and female adults of all the species of Tortopus and Tortopsis are presented, as well as line drawings, pictures and SEM photographs of important structures.

We propose and describe a new genus of interstitial Paramesochridae, Maliithipon gen. nov., to accommodate three species. Maliithipon wellsi sp. nov., type species of the genus, is described based on specimens collected in two sandy beaches in Isla Verde, the Philippines. Apodopsyllus aberrans Mielke, 1984a described from Panama, is allocated to the herein erected genus as Maliithipon aberrans (Mielke, 1984a) comb. nov. Maliithipon cf. aberrans is described, based on specimens collected in the Azores and previously identified as Apodopsyllus aberrans. The new genus is characterized by several distinct morphological features: mandible with uniramous, 2-segmented palp and gnathobase with thin and pointed teeth; maxillule with reduced armature, lacking endopod and exopod; maxilla large, with three syncoxal endites and endopod with reduced setal number; P5 very reduced in both sexes; caudal rami with six setae, two of which (setae III and VI) transformed; pseudoperculum well-developed, with four-lobed distal margin. The new genus is included in the subfamily Paramesochrinae Lang, 1944 and in the genus-group Scottopsyllus (sensu Huys, 1987). It has strong affinities with Leptopsyllus (Leptopsyllus) platyspinosus Mielke, 1984b and Wellsopsyllus (Intermediopsyllus) smirnovi (Kunz, 1992), which are considered as species inquirendae in this paper. Some remarks on the ecology and geonemy of the three studied species are provided. We also list the accompanying Paramesochridae obtained from the two new collecting sites of the genus, and all the genera of Paramesochridae recorded from other sites in the Philippines during the same survey.

We revise the genus Acanthoctenus Keyserling, 1877 recognizing thirteen valid species, of which five are new species and two are re-validated. Further, we find one new synonymy and transfer one species. We describe Acanthoctenus alux sp. nov. from Guatemala, A. chickeringi sp. nov. and A. lamarrei sp. nov. from Panama, A. manauara sp. nov. from Brazil and A. torotoro sp. nov. from Bolivia. We revalidate Acanthoctenus dumicola Simon, 1906 stat. res. from Venezuela, and A. virginea (Kraus, 1955) stat. res., comb. nov. from El Salvador. We transfer Acanthoctenus mammifer to Viracucha mammifer (Mello-Leitão, 1939) comb. nov., from Brazil. Acanthoctenus maculatus Petrunkevitch, 1925 and Gephyroctenus kolosvaryi Caporiacco, 1947 are considered species inquirendae in Acanthocteninae and Ctenidae, respectively, and A. obauratus Simon, 1906 and A. rubrotaeniatus Mello-Leitão, 1947 are considered incertae sedis in Acanthocteninae and Acantheinae, respectively. We also describe for the first time the female of Acanthoctenus spiniger Keyserling, 1877, the type species of the genus. We provide illustrations of male and female diagnostic characters, genitalia, habitus, and measurements to support the genus re-description and further identification of its species. We yield a distributional map of the specimens recorded and the description of the natural history of Acanthoctenus manauara sp. nov.

A revision of the subfamily Microscaphidiinae Looss, 1900 is presented and characters of taxonomic significance discussed. The genus Microscaphidium Looss, 1900, contains M. reticulare (van Beneden, 1859) Looss, 1901 (synonyms M. japonicum Oguro, 1941; M. caballeroi Groschaft, 1977); M. aberrans Looss, 1902 (synonym M. reticulare in part); and M, warui, sp. nov. Confusion in the literature over the identities of M. reticulare and M. aberrans is discussed. A neotype is selected for the former species and a lectotype for the latter. Polyangium linguatula (Looss, 1899) Looss, 1902 (synonyms P. miyajimai Kobayashi, 1921; P. colymbi Poche, 1925; P. longiseminale Chattopadhyaya, 1972) is the sole species in Polyangium Looss, 1902. The genus Angiodictyum Looss, 1902 contains A. parallelum (Looss, 1901) Looss, 1902; A. posterovitellatum Chattopadhyaya, 1972; A. longum, sp, nov.; A. glossoides, sp. nov. Polygorgyra, gen. nov., is proposed for P. cholados, sp. nov. Microscaphidium chelonei Chattopadhyaya, 1972 nec Mehrotra, 1973 and Angiodictyum anteroporum Chattopadhyaya, 1972 are regarded as species inquirendae. Microscaphidium chelonei Mehrotra, 1973 nec Chattopadhyaya, 1972 is a nomen nudum. The following species are recorded for the first time from the green turtle, Chelonia mydas (L.) in Australian waters: Microscaphidium reticulare; M. aberrans; M. warui; Angiodictyum posterovitellatum; A. longum; Polygorgyra cholados.

A new genus of gnaphosid spiders, Almafuerte, gen. nov., is described for seven species from Southern South America. The new genus is diagnosed by a conspicuous retrolateral tegular projection on the male palp, and by having three teeth on the cheliceral retromargin. It comprises six species from Argentina, A. peripampasica sp. nov. (type species), from Central Argentina, also present in Uruguay, A. kuru sp. nov., from Santiago del Estero, A. vigorosa sp. nov., from Corrientes, A. goloboffi sp. nov., from Salta and Jujuy, A. remota sp. nov., from Santiago del Estero and Mendoza, and A. giaii (Gerschman & Schiapelli) comb. nov., here transferred from Echemus, from Santa Fe (the female is here described by the first time); and one species from Bolivia, A. facon sp. nov., from Cochabamba. Hypotheses of relationships of the new taxa are briefly discussed, in the context of the previously proposed groupings: the subfamilies Echeminae and Drassodinae (sensu Platnick 1990) and the “Echemus group” (sensu Murphy 2007).

The new genus Callivelia is proposed to hold three Neotropical species previously held within Paravelia: type-species Callivelia conata (Hungerford), Callivelia taipiensis (Cheesman) and Callivelia bipunctata (Rodrigues, Moreira, Nieser, Chen & Melo). Paravelia virtutis (Drake & Harris) 1935 is synonymized under Callivelia taipiensis (Cheesman) 1926. In addition, a new species, C. anomala, is described from the Amazon Basin of Brazil. Additional distributional records are provided for the three previously described species treated, including the first country record for C. bipunctata in Paraguay. A key to the species of Callivelia is provided, accompanied by color habitus photographs for all three species, and additional photographs of key generic characters.

The Genera of Fungi series, of which this is the sixth contribution, links type species of fungal genera to their morphology and DNA sequence data. Five genera of microfungi are treated in this study, with new species introduced in Arthrographis, Melnikomyces, and Verruconis. The genus Thysanorea is emended and two new species and nine combinations are proposed. Kramasamuha sibika, the type species of the genus, is provided with DNA sequence data for first time and shown to be a member of Helminthosphaeriaceae (Sordariomycetes). Aureoconidiella is introduced as a new genus representing a new lineage in the Dothideomycetes.

Tettigonia sanguinicollis Latreille, 1811, and its junior synonym Tettigonia farinaria Amyot & Serville, 1843, are herein transferred to the genus Onega Distant, 1908. Thus, the previously incertae sedis genus Paragonalia Evans, 1947 (type-species: T. sanguinicollis), becomes a new junior synonym of Onega. Onega sanguinicollis comb. nov. is redescribed and its female genitalia are described and illustrated for the first time. A color variant of Onega fassli Young, 1977 is described. Three new species of Onega are described and illustrated: O. freytagi sp. nov. from Colombia (Cauca Department), O. krameri sp. nov. from Ecuador (Azuay and Bol var provinces), and O. orphne sp. nov. from Ecuador (Bol var and Pichincha provinces). A key to all nine species now included in Onega is provided along with notes on the distribution of the species. O. bracteata Young, 1977 is newly recorded from Azuay province (Ecuador) and Jun n and Pasco departments (Peru), and O. fassli is newly recorded from Ecuador (Napo Province) and Cundimarca Department (Colombia). Records of Onega from Cuba are considered doubtful.

Abstract ‘Paraphiomys’ simonsi is a phiomorph rodent from the early Oligocene of Egypt (~29–30 Mya) that has historically been aligned with much younger (< ~20 Mya) Miocene species of the genera Paraphiomys and Neosciuromys. Here, we use Bayesian tip-dating analysis of a 109-character morphological matrix containing 57 living and extinct ctenohystricans to test these proposed placements for ‘Paraphiomys’ simonsi. Our analyses provide support for the exclusion of ‘Paraphiomys’ simonsi from both Paraphiomys and Neosciuromys and justify the establishment of a new genus (Monamys gen. nov.) for this stem thryonomyoid. These analyses also indicate that the divergence of the extant dassie rat Petromus from the extant cane rat Thryonomys (i.e. origin of crown Thryonomyoidea) occurred ~23.7 Mya, close to the Oligocene–Miocene boundary and in close agreement with recent molecular estimates for this split. Miocene Neosciuromys, Paraulacodus, Protohummus and the type species of Paraphiomys are identified as stem thryonomyids, whereas the Namibian species Apodecter stromeri, Tufamys woodi, ‘Paraphiomys’ australis and ‘Paraphiomys’ roessneri are identified for the first time as stem petromurids, raising the possibility of a long period of endemic petromurid evolution in south-west Africa. Comparison of molecular divergence estimates with our optimal tip-dated topology suggests that stem bathyergoids are most likely to have arisen from late Eocene and early Oligocene ‘phiomyids’.
