Three new species of the genus Centromerus from Italy, C. tongiorgii sp. nov., C. hanseni sp. nov., and C. gatoi sp. nov., are described for the first time on the basis of both male and female specimens. Their relationships with other congeneric species, as well as their diagnoses, are discussed using morphological characters. New records of poorly known species of Centromerus from Italy are furthermore reported. Among them, C. desmeti Bosmans, 1986 is reported for the first time for the Italian fauna and for continental Europe.

The Mediterranean specimens of the genus Microporella collected from shallow water habitats during several surveys and cruises undertaken mostly off the Italian coast are revised. As a result of the disentanglement of the M. ciliata complex and the examination of new material, three new species, M. bicollarissp. nov., M. ichnusaesp. nov., and M. pachyspinasp. nov., are described from submarine caves or associated with seagrasses and algae. An additional species Microporella sp. A, distinct by its finely reticulate ascopore, is described but left in open nomenclature owing to the limitations of a single infertile fragment. After examination of all available material, based on their identical zooidal morphology, the genus Diporula is regarded as junior synonym of Microporella and the combination Microporella verrucosa is resurrected as first suggested by Neviani in 1896. Fenestrulina joannae is also reassigned to Microporella. The availability of a large number of colonies of the above-mentioned and other species already well known from the area (i.e., M. appendiculata, M. ciliata, and M. modesta), allowed the assessment of their high intraspecific variability as well as the observation, for the first time, of some morphological characters including ancestrulae, early astogeny, and kenozooids. Finally, M. modesta, in spite of M. ciliata as defined by the neotype selected by Kukliński & Taylor in 2008, appears to be the commonest species in the basin.

Neomuscina Townsend includes 41 species distributed throughout the Nearctic and Neotropical Regions. Although the genus has a large number of species, it has been ignored and its taxonomy is confusing and has many flaws. In this work we analyzed the following species recorded for Brazil: Neomuscina atincta Snyder, N. atincticosta Snyder, N. capalta Snyder, N. currani Snyder, N. douradensis Lopes & Khouri, N. goianensis Lopes & Khouri, N. inflexa (Stein), N. instabilis Snyder, N. mediana Snyder, N. mimosa Lopes & Khouri, N. neosimilis Snyder, N. nigricosta Snyder, N. paramediana Lopes & Khouri, N. pictipennis pictipennis (Bigot), N. ponti Lopes & Khouri, N. sanespra Snyder, N. schadei Snyder, N. similata Snyder, N. stabilis (Stein), N. transporta Snyder, N. vitoriae Lopes & Khouri and N. zosteris (Shannon & Del Ponte). Neomuscina nigricosta and N. transporta are new distribution records for Brazil. Three new species are described: Neomuscina anajeensis sp. nov. from Anagé (Bahia), Neomuscina maculata sp. nov. from Botelhos (Minas Gerais) and Neomuscina snyderi sp. nov. from Mata de São João (Bahia). An identification key based on the morphological characters of both male and female is provided. Species distributions are discussed and updated, and the number of species now recorded for Brazil is 29.

The E. ovina group of species is proposed here to include Edessa ovina Dallas, 1851 from Trinidad and Tobago, Colombia, Paraguay, Brazil, Argentina (new records) and Guyana; E. impura Bergroth, 1891 from Brazil and Argentina (new record); E. sahlbergii Stål, 1872 restricted to Brazil; and E. graziae sp. nov. from Brazil and Argentina. The E. ovina group can be identified by the apex of the second pair of wings narrowing distally and by a tumid area on the ventral surface of the pygophore (male genitalia) projected posteriorly. Descriptions, measurements, and illustrations of the metasternal process, external and internal genitalia of male and female are provided. A map with the distribution of the species is presented. The holotype of Edessa ovina is designated here. Edessa argali Breddin, 1903 is considered a junior synonym of E. impura. Females of E. ovina and E. impura, and male of E. sahlbergii are described for the first time.

Spathipheromyia Bigot is a small group of predaceous muscids endemic of the Neotropical region. Currently, the genus includes 14 species of which only Spathipheromyia atra Malloch, 1934, S. magellani Malloch, 1934 and S. guttipennis (Thomson, 1869) are listed for Argentina. We present a new species Spathipheromyia goliat sp. nov. for Argentina and registered S. albiceps Malloch, 1934 for the first time for Argentina. Also we present a more detailed description of male and female terminalia of S. albiceps, S. atra, and S. guttipennis, notes on their habitat, new records, a key to species, and a discussion on structure of male terminalia.

In this study, two new species of Helobdella leeches, Helobdella octatestisaca n. sp. and Helobdella melananus n. sp., and a newly recorded species, Helobdella europaea, are reported. Morphological characters and DNA barcode analysis were used to identify the three new species. The differences between these species and other morphologically congeneric species were also compared. In addition, the potential ecological impact of these species was discussed and a checklist of the hirudinea fauna in Taiwan, including eight species in Family Glossiphoniidae, four in Hirudinidae, two in Haemopidae, two in Haemadipsidae, and two in Salifidae, was provided.

Representatives of the Southeast Asian pholcid spider genus Uthina Simon, 1893 have been thought to be very homogeneous in their ecology and morphology. The 14 previously known species all inhabit near-ground microhabitats and cave entrances, and range from pale to dark brown in colour. Even their genitalia are partly very similar, with some species pairs being barely distinguishable based on morphological characters. Here we describe three new species from Bali, Java and Sulawesi that represent three further microhabitats and demonstrate considerable ecological and morphological diversity within the genus: U. maya, sp. nov. from Bali is a large dark species on tree trunks; U. hylobatea, sp. nov. from Bali and eastern Java is a pale leaf-dwelling species that exhibits colour dimorphism; and U. mimpi, sp. nov. is a pale troglomorphic species collected in the aphotic zones of two South Sulawesi caves. In addition, we present new data for five previously described species, including ultrastructure, natural history, new records, taxonomic notes and a description of the previously unknown female of Uthina khaosokensis Yao, Li & Jäger, 2014. Molecular data suggest that all previously described species are very closely related to each other (constituting the monophyletic luzonica-group), and that the three new species represent separate clades within the genus. However, the basal trichotomy could not be resolved: U. maya + (U. hylobatea + U. mimpi) + luzonica-group.

AbstractIn recent years, no less than five new species of early turtles have been described worldwide. Among them are three new turtles from Middle Jurassic deposits that partially fill a previous temporal and morphological gap in our knowledge of the early evolution of these shelled amniotes: Heckerochelys romani, Condorchelys antiqua and Eileanchelys waldmani. For the first time, the phylogenetic position of these three new species is tested in the context of the two presently competing cladistic models of turtle evolution. The addition of these taxa to each matrix does not favour or alter any of the two opposed hypotheses. However, it is demonstrated here that, by documenting yet unknown stages in the evolution of several morphological structures, these three species give stronger support to the model of an extended phylogenetic stem for turtles. These new lines of evidence include the structure of the vomer, the position of the aditus canalis stapedio-temporalis and of the posterior opening of the canalis cavernosus, and the morphology of the processus interfenestralis of the opisthotic.Recent discoveries also reinvigorate the debate about the palaeoecology of early turtles. Whereas simple morphological characters (e.g., shell fontanelle, ligamentous bridge, flattened carapace) can be misleading, forelimb proportions and shell bone histology have led to the conclusion that most stem turtles (i.e., Proganochelys quenstedti, Palaeochersis talampayensis, Proterochersis robusta, Kayentachelys aprix and meiolaniids) were terrestrial forms. At least two out of the five recently described early turtles have been convincingly interpreted as having aquatic habits: Odontochelys semitestacea and Eileanchelys waldmani. More investigation is needed, but this will undoubtedly trigger further debate on the primitive ecology of turtles and on the origin of aquatic habits in testudines (i.e., the crown-group), respectively.

A new species of Glaphyridae is described: Pygopleurus rapuzzii n. sp. from northwestern Iran. The new species is sympatric with and shares many character states with P. anahitae Mitter, from which it can be differentiated by the shape of genital parts and by morphological characters of head, pronotum, and elytra. Both species are illustrated for the first time. New records from Iran are given for other species of the genus Pygopleurus Motschulsky.
