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

The ability of beetles to form defensive spheres is a rare trait and confined to representatives in the families Clambidae, Leiodidae and Hybosoridae. However, the most compact spheres are formed by members of the Neotropical genus Ceratocanthus (Ceratocanthinae: Hybosoridae). A representative in Dominican amber described as Ceratocanthus emarginatus sp.n. differs from all known members of the genus by its unique notched clypeus. Additional specimens of at least two other species suggest that these sphere-forming beetles were fairly diverse in the Dominican amber forest. http://www.zoobank.org/urn:lsid:zoobank.org:pub:4329D0DA-57BD-4CEA-9464-ABD5D1577FC9 相似文献

The heteronemertean genus Lineus Sowerby, 1806 has been badly in need of revision because of its apparent non-monophyly. In this paper, we focus on Lineus torquatus Coe, 1901, one of the heteronemertean species that occur commonly in waters around the North Pacific, as well as a few other allied species distributed in the western North Pacific, including Lineus alborostratus Takakura, 1898 and Cerebratulus montgomeryi Coe, 1901. Based on phylogenetic analyses using 16S, COI, 28S, 18S, and H3 gene and ITS sequences, we detected a well-supported clade comprised of heteronemerteans with a frontal white band on the head, to which we add Kulikovia gen. nov. This genus is nested within a more comprehensive, highly supported clade, here named the Siphonenteron-clade, which contains Tenuilineus bicolour (Verrill, 1892), Lineus flavescens Coe, 1905, Siphonenteron bilineatum (Renier, 1804), S. cf. bilineatum, Lineus cf. caputornatus, and Lineus sp. from Guam. Our analyses confirmed the presence of a cryptic species of what was formerly known as the cherry-red and reddish forms of Lineus torquatus, herein described as Kulikovia manchenkoi sp. nov. based on some external characters, internal morphology, and the four genetic markers ( COI, 16S, H3, and ITS). In contrast to the species pair K. torquata– K. manchenkoi, the reddish form of K. alborostrata does not differ genetically from the typical form of this species. The significance of the external and internal characters for distinguishing cryptic species is discussed. http://zoobank.org/urn:lsid:zoobank.org:pub:9BECBC60-9C82-48EC-AD36-FC564D82A5BChttp://zoobank.org/urn:lsid:zoobank.org:act:D02B2339-4F65-4517-9B13-DD4AAB0C55C5http://zoobank.org/urn:lsid:zoobank.org:act:8D239B62-E655-4721-90F0-A4944DD8A3C7 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

In a survey of the mollusc fauna of the Ceyhan River Basin, including rivers, natural lakes, dam lakes and springs between June 2008 and September 2014, a total of 20 species of Gastropoda and 8 species of Bivalvia were identified. Two of these species are new to science, and for one of them a new genus is erected: the hydrobiid Hemite ceyhanensis gen. n., sp. n., and the bithyniid Pseudobithynia cocussusica sp. n. http://www.zoobank.org/urn:lsid:zoobank.org:pub:DE5FFC19-13CD-4B81-B74E-80059E781518 相似文献

A new miniature species of geophilomorph centipede, Ityphilus grismadoi sp. nov. (Chilopoda: Geophilomorpha: Ballophilidae) is fully described and illustrated on the basis of specimens collected in Yasuní Scientific Station and Jatun Sacha Biological Station, both located in the Ecuadorian Amazon. The new species is characterized by having the internal edge of the forcipular tarsungulum completely smooth, this trait being shared by six other Neotropical members of the genus Ityphilus Cook, 1899; and another species ( I. cifuentesi Cupul Magaña, 2014) from the transition area between the Neotropical and Nearctic regions. Ityphilus grismadoi sp. nov. is distinguished from these seven species by the low number of leg-bearing segments (37, 39), and the very small body size (7–9 mm in length) and for a confident identification it is compared in detail with those having a roughly similar range of leg-bearing segments. This is the first record of the genus Ityphilus from Ecuador and the second report of a ballophilid centipede from the country (the other represented by Zygethmus pantenus Chamberlin, 1957). A key to the Neotropical members of Ityphilus with forcipular tarsungulum smooth (including I. cifuentesi) is also given. http://zoobank.org/urn:lsid:zoobank.org:pub:32F77890-9DC5-47AC-A794-29C4437C3B93http://zoobank.org/urn:lsid:zoobank.org:act:3EB64970-F159-4C6E-B9FF-AF9D09128553 相似文献

A new species of the family Zerconidae, Zercon persicus sp. n., is described based on female and male morphological characters. It was collected in West Azarbaijan province (northwestern Iran). Idiosomal chaetotaxy, poroidotaxy and related notations are illustrated. The similarities and differences between the related species within the genus are discussed. Records of some other Zercon species from the province are given for the first time. http://www.zoobank.org/urn:lsid:zoobank.org:pub:3D1122C7-2B86-40D2-974E-EE69035A2413 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

Larissamya comta gen. n., sp. n., is described from Kuwait Bay, northern Arabian Gulf. The hinge is identical to that seen in Kurtiella and Montacutona but the spined dorsal margin is unique. Anatomically Larissamya differs from Kurtiella in retaining both gill demibranchs and from both Kurtiella and Montacutona in having greatly unequal adductor muscles. Co-occurrence and density data suggest that L. comta may be associated with the ophuroid Amphiura fasciata. http://www.zoobank.org/urn:lsid:zoobank.org:pub:ECCB79FC-6EB2-4693-B1D4A014CB17C6D8 相似文献
