Macquaridrilus mcmurtrieae n. sp. is described from Campbell Island. This resembles the only other species in the genus, Macquaridrilus bennettae Jamieson, 1968, in most aspects, but shows significant differences in the anatomy of its genitalia. In particular, the spermathecal pores are dorsal rather than lateral, the spermathecae lack diverticulae, the ejaculatory duct is more stout and muscular, the vas deferens is shorter relative to other organs and the anterior prostate is compact rather than elongate. The presence of a cuticular sperm canal appears to be an apomorphy for the genus. The new species was collected from streams and tarns across the island. http://zoobank.org/urn:lsid:zoobank.org:pub:652AF61D-CFB2-4D07-94C8-59E6FB549D5Fhttp://zoobank.org/urn:lsid:zoobank.org:act:984F2456-768D-48A1-87AD-4453768BAB8A 相似文献

Three new species of Crenitis Bedel, 1881 are described from South Africa; C. castellus sp.n. and C. rupestris sp. n. from the KwaZulu-Natal Drakensberg, and C. quagga sp.n. from the Western Cape Province. All three new species were found in madicolous habitats, which appear to be characteristic for a number of species of the genus. A revised key to African species of Crenitis is included. http://zoobank.org/urn:lsid:zoobank.org:pub:18BE876C-46CB-4AD5-9BB0-EA6F8D711F09 相似文献

Herein we describe a new species of Teratoscincus Strauch, 1863 from remote desert areas of the Sistan and Baluchistan Province in southeastern Iran. Based on morphological characters, this species, Teratoscincus sistanense sp. n., has a close relationship with T. microlepis and is distinct from all other members of its genus by the number of small scales around the midbody. We provide information about the ecology, biology and conservation of this new species. A comparison with the other three Iranian species of Teratoscincus and an updated key to this genus in Iran are presented. http://www.zoobank.org/urn:lsid:zoobank.org:pub:77F54322-6CCA-46F1-A74B-B8A75E1F1F8D 相似文献

The marine microgastropod genus Scalaronoba Powell, 1927 (Gastropoda: Aclididae?) is recorded from Australia for the first time, with the new species Scalaronoba kryptopleurakia n. sp. and Scalaronoba arenula n. sp. described from central Victoria. Three other indeterminate Victorian specimens are illustrated and discussed. These are the first records for the genus outside New Zealand. The uncertainty of the familial placement of Scalaronoba is discussed. These species are noted as being amongst the smallest gastropods to be recorded from Victorian waters. http://www.zoobank.org/urn:lsid:zoobank.org:pub:98860E57-6EC0-4F15-93D7-34A823E41E07 相似文献

A new species of dasypodid armadillo (Xenarthra, Cingulata), Anadasypus aequatorianus, from the late Miocene of Ecuador is described. The remains were collected in sediments of the Letrero Formation, Nabón Basin, which is part of several intermontane basins related to Andean uplift. The genus represents the oldest record of Dasypodini, which also encompasses Propraopus (Pleistocene–early Holocene) and Dasypus (?Miocene–Recent). The new species is based on several osteoderms, which show more derived features than Anadasypus hondanus, from the middle Miocene of Colombia. In order to test the affinities of A. aequatorianus within Dasypodini, we conducted a cladistic analysis of 24 morphological characters for 10 taxa. The most parsimonious tree supports the generic attribution of the new species and places Anadasypus basal to Propraopus and Dasypus, agreeing with the stratigraphic evidence. The faunas from tropical Andean areas differ noticeably from the better-known assemblages of the classic South American sequences. In the case of dasypodines, their geochronological distribution shows that they were historically restricted to tropical and subtropical environments and the main cladogenetic events of the group probably occurred at lower latitudes. In this context, the taxon described herein fills important temporal and geographic gaps of early Neogene armadillos from intertropical areas. http://www.zoobank.org/urn:lsid:zoobank.org:pub:9DC76603-D831-4E68-BE55-90113228E0F4 相似文献

The genus Pseudaeginella is analysed herein by cladistic methods based on a morphological data matrix of 49 characters × 18 terminal taxa. Based on the results, we comment on the phylogenetic position of Paradeutella within Pseudaeginella, and we propose Pseudaeginella multispinosa comb. nov. and Pseudaeginella tanzaniensis comb. nov. Pseudaeginella freirei sp. nov. is described from the Abrolhos Bank, north-eastern Brazil. We provide an updated key to the Pseudaeginella species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:F573E845-822E-41D6-8F58-FE54C5653A53 相似文献

A new species of the dipteran family Sciomyzidae is described from Iran: Limnia kassebeeri sp. n., which is similar to L. unguicornis (Scopoli, 1763) and L. paludicola Elberg, 1965, but differs from them by the reticulate pattern on the anal cell, the presence of one small seta on the anepisternum, in addition to fine hairs and the features of the genitalia. http://www.zoobank.org/urn:lsid:zoobank.org:pub:FCD0AD91-E21D-44CA-9D11-90DE5A92F52D 相似文献

A new and phylogenetically basal species of Carpolestes, the youngest and most derived genus of the plesiadapoid family Carpolestidae in North America, is described from a late Tiffanian (Ti-5) site in Sweetwater County, Wyoming, USA. Carpolestids differ from closely related plesiadapoid clades in having an enlarged, multicuspidate, blade-like P 4 that is partly convergent on that of multituberculates and other mammals showing plagiaulacoid dental adaptations. With some notable exceptions, the evolutionary history of North American carpolestids is characterized by the progressive development of larger and more elaborate P 4 blades through time. In particular, species of the monophyletic genus Carpolestes differ from species assigned to the earlier and apparently paraphyletic genus Carpodaptes in terms of both the size and shape of their P 4. A geometric morphometric analysis reveals that, with respect to P 4 shape, the closest approximation to the highly derived morphology of Carpolestes is made by Carpodaptes hobackensis, which is one of the smallest known species of Carpodaptes. In contrast, the largest known species of Carpodaptes, Carpodaptes jepseni, has a P 4 that falls within the metric range of variation for species of Carpolestes, yet Carpodaptes jepseni shows a uniquely derived P 4 shape that seems to exclude it from any special phylogenetic relationship with Carpolestes. A phylogenetic analysis based on dental characters reconstructs Carpodaptes hobackensis as the sister group of the Carpolestes clade. Shape seems to have been a more important factor than size during the final transformation of the blade-like P 4 of North American carpolestids. http://zoobank.org/urn:lsid:zoobank.org:pub:212F9ECC-DA9A-44F8-BE7E-43F3EBAD636A 相似文献
