We describe adult specimens and tadpoles of a new species of Telmatobius Wiegmann, 1834, Telmatobius mantaro, from the central Cordillera of the Andes in Peru. Specimens were collected in humid lower montane forests and dry lower montane forests between 2240–3170 m elevation at the northern parts of the Departments of Huancavelica and Ayacucho. We also report a range extension of 262 km west of the type locality for Telmatobius mendelsoniDe la Riva et al., 2012, which was found in sympatry with T. mantaro in Ayacucho. The new species has a snout-vent length of 48.9–55.8 mm in three adult males, and both sexes have tympanic membrane differentiated and tympanic annulus visible, a feature that distinguishes the new species from the majority of other Peruvian Telmatobius. We propose to assign the IUCN category Critically Endangered to this species because of its small area of distribution and its high likelihood of being infected by Batrachochytrium dendrobatidis.
Small mammal ecology and natural history are poorly known in Nuclear Central America. In an effort to gain information on small mammals (insectivorans, marsupials, and rodents), we sampled three cloud forest habitats in mountain ranges in Honduras (Cerro Celaque and Sierra de Agalta) and Guatemala (Sierra de las Minas). Small mammals were collected using removal trapping. A total of 789 specimens representing 23 species of small mammal was recorded from seven trapping sites. Trapping effort varied among sites, with a total of 18,117 total trap nights recorded. We describe the habitat at each trapping site, and report on species diversity, relative abundance, sex ratios, reproductive activity, and other natural history information on the mammals collected. In general, cloud forests in the three mountain ranges contained different communities of small mammals. We recorded only three species, Heteromys desmarestianus Gray, 1862, Peromyscus oaxacensis Merriam, 1898, and Scotinomys teguina (Alston, 1877), on all three mountain ranges.
The Lower Permian Dunkard Group has yielded a sparse record of tetrapod footprints that are assigned to the ichnogenera DimetropusRomer and Price, 1940, DromopusMarsh, 1894, and LimnopusMarsh, 1894. We report two new occurrences of Dimetropus that significantly extend its stratigraphic range in the Dunkard Group to the Washington and Greene formations. The only previous Dunkard record of Dimetropus is of D. berea (Tilton, 1931), the type ichnospecies of the ichnogenus, from the Waynesburg Formation of West Virginia. Dimetropus (eupelycosaur), Dromopus (araeoscelid), and Limnopus (large temnospondyl) footprints are present in many Late Pennsylvanian-Early Permian footprint assemblages. The Dunkard footprints of Dimetropus reported here are very large for the ichnogenus, so it seems likely they were made by one of the relatively large eupelycosaurs, Dimetrodon Cope, 1877, Ophiacodon Marsh, 1878, or Ctenospondylus Romer, 1936, known from Dunkard Group body fossils.
Thirty-five species of fleas are documented from the state of West Virginia including new state records for the ischnopsyllid, Nycteridopsylla chapini Jordan, 1929, and the ctenophthalmid, Corrodopsylla curvata (Rothschild, 1915). Host and distribution records are presented by county, with many new records, including 88 new county records amassed since 1980. The most widely distributed fleas were Orchopeas leucopus (Baker, 1904) and Peromyscopsylla hesperomys hesperomys (Baker, 1904), both from mice of the genus Peromyscus. Ctenophthalmus pseudagyrtes (Baker, 1904) was abundant on shrews, voles, and mice. The squirrel flea, Orchopeas howardi (Baker, 1895), found in 12 counties from west to east in the state is probably present throughout the state. This species has been implicated in the maintenance and spread of sporadic epidemic typhus. The cat flea, Ctenocephalides felis (Bouché, 1835), a parasite primarily of domestic cats and dogs, was not well represented in our collections, but is widespread geographically and probably occurs throughout the state. This is the most economically important species in West Virginia as a household pest and carrier of several zoonotic human pathogens.
The flea genus RectidigitusHolland, 1969, endemic to Papua New Guinea and Papua Province, Indonesia is reviewed as a continuation of the study of fleas in the Robert Traub flea collection deposited in the Carnegie Museum of Natural History, Pittsburgh, Pennsylvania. This paper (Part IV) is an extension of previous studies by Hastriter (2012), Hastriter and Easton (2013, Part I, Striopsylla), Hastriter (2014, Part II, Nestivalius, Orthopsylloides, and Parastivalius), and Hastriter (2015, Part III, Traubia). Rectidigitus currently contains four valid species (Mardon 1981): R. ancisus (Jordan, 1937), R. spooneri (M. Rothschild, 1934), R. szentivanyiHolland, 1969, and R. traubiHolland, 1969. The male of R. ancisus is described for the first time and the previously known distribution of this species is expanded from Morobe Province to Southern Highlands and Western Highlands Provinces. An additional four new species of Rectidigitus are described herein (R. angularis, R. claviculatus, R. dittmarae, and R. glomerospinosus). With the description of these four new species, the total number of described species in the superfamily Pygiopsylloidea in Papua Province, (Indonesia), Papua New Guinea (including Bismarck Archipelago), and the Solomon Islands is 105. An additional eight species belonging to three other flea families (Ischnopsyllidae (3), Pulicidae (3), and Leptopsyllidae (2)) bring the total number of flea taxa to 113 species (including subspecies). A key to the species of Rectidigitus is provided.
