Although most taxa were found in freshwater, three are marine, one occurred in brackish water and Protoplanella simplex Reisinger, 1924 was even collected in a dry, limnoterrestrial habitat. Four taxa are new to science. Castradapurgatorialis n. sp., Cas-tradaparadisea n. sp. and Strongylostoma devleeschouweri n. sp., all belong to the Typhloplanidae Graff, 1905. The first two species differ from other species of Castrada Schmidt, 1861 by the presence of a large accessory bursa and the morphology of the copulatory atrium. C. purgatorialis n. sp. has zoochlorellae while these are lacking in C. paradisea n. sp. Strongylostoma devleeschouweri n.sp. is unique because of its coalescing testes and because of the presence of a sphincter around the stalk of the seminal receptacle. Gieysztoria iberica n. sp. belongs to the Dalyelliidae Graff, 1905 and is characterized by the extreme length of the girdle of the stylet. Except for five taxa, all specimens were collected within the boundaries of the Doiiana National Park. Most of the taxa could easily be identified to species level except for one taxon of Kytorhynchidae Rieger, 1974 and one species ofPhaenocora Ehrenberg, 1836. Four species are new for the Iberian Peninsula. Three of these, Trigonostomum penicillatum (Schmidt, 1857) Micoletzky, 1910, Promesostoma maculosum Ax, 1956 and Gieysztoria macrovariata (Weise, 1942) Ruebush & Hayes, 1939, were already known from other European localities, whereas Parapharyngiella involucrum Willems et al, 2005, a marine species, has previously only been found in Zanzibar, Tanzania.

    Designation of a neotype for the Brazilian porcupine, Coendou prehensilis (Linnaeus, 1758)

    查看更多>>摘要：The Brazilian porcupine was one of several species described and illustrated by the 17th-century naturalist Georg Marc-grave, whose text was among the primary references upon which Linnaeus based his Hystrixprehensilis. As currently understood, Coendou prehensilis is a wide-ranging polytypic taxon that has never been revised and may represent a complex of closely related species. Given that no name-bearing type specimen of C. prehensilis is believed to be extant, and in order to avoid ambiguous application of this name, we designate a specimen collected at the type locality in Pernambuco, northeastern Brazil, as the neotype for Hystrix prehensilis Linnaeus. The geographic distribution of mitochondrial DNA hap-lotypes suggests that specimens from west-central Brazil previously identified as "Coendou prehensilis'" belong to a different species, but only a comprehensive taxonomic revision of the genus will shed light on species limits and the geographic ranges of C. prehensilis and other congeneric forms.

    Competing generic concepts for Blanding's, Pacific and European pond turtles (Emydoidea, Actinemys and Emys)—Which is best?

Two of its former species, now Glyptemys insculpta and G. muhlenbergii, constitute a well-supported basal clade within the Emydinae. However, the phylogenetic position of the other two species traditionally placed in Clemmys remains controversial. Mitochondrial data suggest a clade embracing Actinemys (formerly Clemmys) marmorata,Emydoidea and Emys and as its sister either another clade (Clemmys guttata + Terrapene) or Terrapene alone. In contrast, nuclear genomic data yield conflicting results, depending on which genes are used. Either Clemmys guttata is revealed as sister to {{Emydoidea + Emys) + Actinemys) + Terrapene or Clemmys guttata is sister to Actinemys marmorata and these two species together are the sister group of (Emydoidea + Emys); Terrapene appears then as sister to (Actinemys marmorata + Clemmys guttata) + (Emydoidea + Emys). The contradictory branching patterns depending from the selected loci are suggestive of lineage sorting problems. Ignoring the unclear phylogenetic position of Actinemys marmorata, one recently proposed classification scheme placed Actinemys marmorata, Emydoidea blandingii, Emys orbicularis, and Emys trinacris in one genus (Emys), while another classification scheme treats Actinemys, Emydoidea, and Emys as distinct genera. The inclusion of Actinemys in the same taxon as Emydoidea + Emys is unacceptable under a phylogenetic classification framework because there is evidence for the non-monophyly of this clade. Moreover, Actinemys, Emydoidea, and Emys are morphologically highly distinct. Their morphological divergence exceeds by far the differences that typically occur among species of the same genus, so that a continued usage of the distinct genera Actinemys, Emydoidea and Emys is recommended.

    Validation of the family Bathyporeiidae (Crustacea, Amphipoda)

    查看更多>>摘要：The family Bathyporeiidae was introduced without description, and later on, when its first proper description appeared, was not considered as new. Therefore, it cannot be currently considered as a valid family. These procedural irregularities are corrected herein, and the the family is described de novo, with Bathyporeia as its type genus. Bousfield & Shih (1994) created a number of amphipod families, which are nomenclaturally invalid, as they were not accompanied by descriptions, as specifically required by Art. 13 of ICZN (1999). However, as in many cases the creation of these families was justified from a systematic point of view, some of them have been used in subsequent systematic literature with Bousfield & Shih (1994) as the authority. The present author became aware of this non-Code compliant situation, when he was carrying out a comparison of the family Liljeborgiidae with its possible relatives. Two of these 'ghost families', the Cheirocratidae and Hornelliidae were discussed in d'Udekemd'Acoz (2010), in which they were validated. The present paper focuses on the similar case of the family Bathyporeiidae, which is validated herein.

    A new species of amphipod, Megamphopus katagani sp. nov. (Crustacea: Peracarida: Photidae) from the Sea of Marmara (Turkey), with a key to the species of Megamphopus in the North Atlantic, Mediterranean and associated Seas

    查看更多>>摘要：A new species of amphipod, Megamphopus katagani sp. nov., is described from the sea of Marmara (Turkey). A key to the species of Megamphopus known from the North-East Atlantic, Mediterranean and associated seas is provided. During a recent survey in the Sea of Marmara (Fig. 1), amphipods were collected from the benthos. Amongst the samples was discovered a species of Megamphopus Norman, 1869 that could not be allocated to any known species. It is described here under the name Megamphopus katagani sp.nov. There are now five species (M. longi-cornis Chevreux, 1911; M. brevidactylus Myers, 1976, M. longidactylus Chevreux, 1925, M. cornutus Norman, 1869 and Megamphopus katagani sp. nov.) of Megamphopus known from the North-East Atlantic, Mediterraneanand associated seas. A key to these species is provided together with a description and figures of the new species.
