This paper gives a systematic revision of feather mites of the genera Dubininia Vassilev, 1958 and Cacatualges Dabert, Badek and Skoracki, 2007 (Xolalgidae: Ingrassiinae) associated with parrots (Aves: Psittaciformes) of the Old World. Five new species are described: Cacatualges probosciger sp. n. from Probosciger aterrimus (Gmelin) (Cacatuidae) from New Guinea, Dubininia charmosynae sp. n. from Charmosyna pulchella Gray GR (Psittaculidae) from New Guinea, D. micropsittae sp. n. from Micropsitta pusio pusio (Scaltter) (Psittaculidae) from New Guinea, D. nestori sp. n. from Nestor notabilis Gould (Strigopidae) from New Zealand, and D. pezopori sp. n. from Pezoporus wallicus (Kerr) (Psittaculidae) from Tasmania, Australia. Four previously described species of Dubininia are redescribed based on material from type hosts: D. curta (Trouessart, 1885) from Platycercus elegans (Gmelin) (Psittaculidae), D. lorina (Trouessart, 1885) from Lorius domicella (Linnaeus) (Psittaculidae), D. melopsittaci Atyeo and Gaud, 1987 from Melopsittacus undulatus (Shaw) (Psittaculidae), and D. psittacina (Trouessart, 1885) from Strigops harboptilus Gray GR (Strigopidae) from New Zealand. A new diagnosis for the genus Dubininia is provided. A key to all presently known Dubininia species is provided for the first time.

The discovery of a new species,Cyclolampas altusnew species in the upper Callovian of Burgundy (France) leads to the systematic revision of the rare echinoid genusCyclolampasPomel, 1883. Two morphometric approaches are used jointly to describe and quantify variations in test shape: the analysis of linear measurements and the Elliptic Fourier shape analysis. Both analyses yield congruent results that highlight the amplitude of within-species variations and quantify the part due to allometry. Along with the description ofC. altus, the systematic position of species formerly assigned to the generaPygorhytisPomel, 1883 andCyclolampasis amended. Previously attributed to the genusPygorhytis,Cyclolampas castanea(Desor, 1858) is reassigned to the genusCyclolampason the base of new observations. Conversely, the examination of the Bajocian speciesPygorhytis kiliani(Lambert, 1909) andPygorhytis gillieroniDesor in Desor and de Loriol, 1872, which were previously assigned toCyclolampasnow supports their taxonomic reassignment to the genusPygorhytis. Finally, the two speciesCyclolampas verneuili(Cotteau, 1870) andCyclolampas cotteauiMintz, 1966 (nomen nudum) are considered junior synonyms of the genus type speciesCyclolampas voltzii(Agassiz, 1839). The questioned origin date of the genus, estimated either to the Bajocian or to the Oxfordian, is now clearly established to be upper Callovian. These new results fit well with the overall scheme of atelostomate echinoid evolution and migration to deep-sea environments during the Middle and Upper Jurassic.

Chondrocyclus Ancey, 1898 is a genus of nine species of African operculate land snails restricted to indigenous forest and mesic thicket. Worn specimens (i.e., without a periostracum or operculum), on which some species descriptions and records were based, appear to be indistinguishable morphologically. A comprehensive revision of Chondrocyclus s.l. is provided here based on comparative morphological examinations of the shell, protoconch, periostracum, operculum, radula and penis, and on mitochondrial genes cytochrome c oxidase subunit I and 16S rRNA. Two genus-level lineages are recognised, Chondrocyclus s.s. and Afrocyclus gen. nov. Revised species descriptions are given for seven species. Two species, C. meredithae Bruggen, 1983 and C. chirindae Bruggen, 1986 both from north of South Africa, are removed from Chondrocyclus. Twelve new species are described: C. herberti sp. nov., C. silvicolus sp. nov., C. amathole sp. nov., C. pondoensis sp. nov., C. devilliersi sp. nov., C. pulcherrimus sp. nov., C. cooperae sp. nov., C. langebergensis sp. nov., C. kevincolei sp. nov., A. oxygala gen. et sp. nov., A. potteri gen. et sp. nov. and A. bhaca gen. et sp. nov. This is the first detailed systematic revision of an Afrotropical cyclophorid group to include morphological and molecular data. This study complements research on other taxa of low-vagility forest-dwelling habitat specialists by providing comparative distribution data for an independent, widespread group. Such evidence is urgently needed for conservation of South Africa’s threatened forest biome.

The early Miocene site of Wadi Moghra, Qattara Depression, Egypt, is important for interpreting anthracothere (Mammalia, Artiodactyla) evolution, because the Moghra sediments preserve a higher diversity of anthracotheres than any other pene-contemporaneous site. New specimens from Moghra are described and form the basis for the systematic revision of Moghra anthracotheres provided here. Among the important discoveries recently made at Moghra is the first complete skull of Sivameryx moneyi. Other new specimens described here include two new species of Afromeryx, and a new genus and species, all of which are unique to Moghra. A review of biogeographic information supports the conclusion that three of the Moghra anthracotheres (Brachyodus depereti, B. mogharensis, and Jaggermeryx naida, n. gen. n. sp.) are members of late surviving lineages with a long history in Africa, while three other species (Afromeryx grex, n. sp., A. palustris, n. sp., and Sivameryx moneyi) represent more recent immigrants from Eurasia.

The south-eastern Australian helicarionid clade currently comprises six genera of snails and semislugs united by genital characters, including an epiphallic flagellum that produces a spiraling, spinose spermatophore, the absence of an epiphallic caecum, and the presence of at most a very short vagina. We comprehensively revise the taxonomy of this group based on comparative analyses of key morphological features and mitochondrial markers COI and 16S, revise the placement of several species described recently on the basis of shell morphology alone, and describe new taxa. The snail genus Brevisentis is monophyletic as currently understood, but includes an additional undescribed species from Wollemi National Park, New South Wales. Mysticarion is shown to contain four arboreal semislugs with wide, disjunct ranges, including one new species (Mysticarion obscurior sp. nov.). We synonymise Fastosarion staffordorum with Mysticarion hyalinus. The semislug Desidarion is synonymised with Parmavitrina, and we describe two new species of this genus, P. flavocarinata sp. nov. and P. maculosa sp. nov. The semi-arboreal semislug Cucullarion is herein included in the south-eastern Australian helicarionid clade based on morphological and genetic evidence, despite its more northerly distribution. Two small semislugs so far placed in Peloparion do not group together and a new genus, Ubiquitarion gen. nov., is described for Peloparion iridis. All of these genera, together with the semislug Helicarion (not included here), form a monophyletic radiation endemic to southeastern Australia.

Potamotrygon scobina Garman, 1913, described from Cametá, rio Tocantins, lower Amazon basin, is taxonomically reviewed through an extensive morphological study of internal and external features. Specimens identified as P. scobina from different locations of the Amazon basin were also studied. The identity of P. scobina, its morphology, and distribution are redefined. In addition, three new species closely related to P. scobina are described from Brazil: Potamotrygon adamastor, sp. nov., from rio Uraricoera, rio Branco system, upper Amazon basin; Potamotrygon amazona, sp. nov., from rio Juruá, upper Amazon basin; and Potamotrygon garmani, sp. nov., from the mid to upper rio Tocantins. These three new species do not occur sympatrically with P. scobina, as far as known. Together with P. scobina and P. limai Fontenelle, Silva & Carvalho, 2014, the new species have three angular cartilages of different sizes, a condition not seen in any other potamotrygonin (which have either one or two angulars). Diagnostic characters in combination are primarily morphometric proportions, especially tail length and width, dermal denticles and tail thorns (their relative size, number, morphology, and distribution), tooth size and number of rows, and color pattern. Printed copy of this book is available from US$24.6 plus postage, Click here to order.

The subgenus Pterygnophos Wehrli, 1951 within the genus Charissa Curtis, 1826 nomen protectum (= Hyposcotis Hübner, [1825] nomen oblitum) is taxonomically revised based on morphology and DNA barcoding. The subgenus comprises four species in total which are presented in detail. Diagnostic characters are depicted and keys to the species based on the morphology of male and female genitalia are provided. Males and females of each species and their genitalia are illustrated. The distribution of all species is described and figured on a map, and a neighbor joining tree based on DNA barcoding of 17 specimens is presented. Charissa (Pterygnophos) beljaevi spec. nov. from Mongolia is described as new. A neotype for Gnophos creperaria Erschoff, 1877, and lectotypes for Gnophos deliciaria shantungensis Wehrli, 1953, Gnophos dorkadiaria Wehrli, 1922, Gnophos ochrofasciata Staudinger, 1895, and Gnophos finitimaria Fuchs, 1899 are designated. The following synonyms are recognized: Gnophos finitimaria Fuchs, 1899 syn. nov. is a synonym of Gnophos ochrofasciata Staudinger, 1895 and Gnophos deliciaria shantungensis Wehrli, 1953 syn. nov. is a synonym of Gnophos agnitaria Staudinger, 1897.

AbstractThe genus Ericydeus Pascoe (Polydrosinae: Naupactini) distributed throughout the United States of America up to Argentina is revised and a cladistic analysis including 16 species is conducted. Three new species are described: E. bahiensis, E. argentinensis and E. cupreolus. Ericydeus humeralis Hustache is synonymized under E. nigropunctatus (Chevrolat); and E. modestus viridans (Boheman) and E. modestus duodecimpunctatus (Dalla-Torre, Emden & Emden) are elevated to species rank. Other valid species are: E. hancocki (Kirby), E. schoenherri (Perty), E. sedecimpunctatus (Linnaeus), E. yucatanus (Champion), E. roseiventris (Champion), E. quadripunctatus (Champion), E. modestus (Gyllenhal), E. forreri (Champion), E. lautus (LeConte) and E. placidus (Horn). In the cladogram obtained the species from South America gather in a clade (E. argentinensis, E. sedecimpunctatus, E. nigropunctatus, E. schoenherri, E. hancocki, and E. bahiensis) and the species from Central and North America form a separate clade (E. yucatanus, E. roseiventris - E. quadripunctatus, E. cupreolus, E. viridans - E. modestus, E. duodecimpunctatus, E. forreri, E. lautus - E. placidus). The character evolution follows a southern-northern direction. The paper includes a redescription of the genus, redescriptions or descriptions of its 16 species, a dichotomous key, habitus photographs, drawings of diagnostic structures, distribution maps, a cladogram, and a discussion of the phylogeny and distribution of the genus.
