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 genus and species, Espanoderus barbarae gen. et sp. nov., belonging to the family Tanyderidae (Diptera, Nematocera), is described from Lower Cretaceous amber of Spain (Álava amber). The new genus is the smallest member of Tanyderinae and the first member of the family from the Álava amber. The position of the new genus in a phylogenetic tree of Tanyderidae is presented. http://zoobank.org/urn:lsid:zoobank.org:pub:EC3284BA-C07F-48AC-8AF5-4F9D2EF4EA6C 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

A new genus and two new species of Kempyninae (Osmylidae), Ponomarenkius excellens gen. et sp. nov. and Arbusella magna sp. nov., are described from the Middle-Upper Jurassic of Daohugou (China). The finding demonstrates that extant kempynins, a typical Gondwanan group, are overshadowed by their Mesozoic relatives in taxonomic diversity and variety of wing venation. Striped patterns of both newly described species are an example of cryptic and disruptive coloration, possibly pinnate leaf mimesis. Eyespot patterns of Arbusella magna sp. nov. can be explained as a result of sexual selection. The abundance and distribution of the Mesozoic kempynins are discussed. http://zoobank.org/urn:lsid:zoobank.org:pub:CF33DEB4-0A69-407D-B1B2-1EC6537E4095 相似文献

The new species Quinquelaophonte aurantius sp.nov. is described, based on specimens collected in Portobello Bay, New Zealand. The species is distinguishable for having long fine setules in the anal operculum distal edge, a breadth ratio of caudal rami length above 3.5, and a rudimentary antenna abexopodal spine. This new species differentiates from Q. parasigmoides and Q. wellsi on the following autapomorphs; short spine-like outer seta in segment 2 of females P3 endopod and the partial reduction of setae in spines from male P3 and P4, longer V-shaped caudal rami, an almost non-existent terminal portion of the antenna exopod with short lateral setae. Phylogenetic analyses demonstrate the position of Quinquelaophonte within the family Laophontidae.

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
