The puffer fishes collected from three different stations (Mudasal odai, Annankoil and Samiyarpettai) included nine different species from five different genera: Lagocephalus, Arothron, Torquigener, Che-lonodon and Takifugu in the order Tetraodontiformes and family Tetraodontidae, viz., Lagocephalus lunar is, Lagocephalus inermis, Arothron reticularis, Arothron hispidus, Arothron stellatus, Arothron immaculatus, Torquigener brevipinnis, Chelonodon patoca and Takifugu oblongus. This study also summarized the distribution and taxonomic positions in terms of species availability and key characters.

    DNA barcoding reveals andropolymorphism in Aclerogamasus species (Acari: Parasitidae)

This study addresses this issue in two occasionally sympatricmite species Aclerogamasus similis (Willmann, 1953) and ,4. holzmannae (Micherdzinski, 1969) collected in Poland. The females of these two taxa are morphologically indistinguishable but males are quite different, and could be either separate species or one species with two male morphs. We address this question by performing molecular assays, testing variation in a fragment of the mtDNA COI gene and the D2 region of 28S rDNA. Molecular analysis of populations revealed very low variation in the studied gene fragments. All sequences of the D2 region of 28S rDNA (size 375 bp) were identical. Only two COI haplotypes were found, differing by two out of 644 nucleotide positions (0.3% K2P distance). The variant haplotype was found in one A. similis male, and probably represents intraspecific variability. The results strongly suggest that all studied females and males belong to only one species with dimorphic males. This finding confirms some earlier opinions on synonymy of both species. Therefore, Aclerogamasus holzmannae (Micherdzinski, 1969) should be regarded as a junior synonym of Aclerogamasus similis (Willmann, 1953). As andropolymorphism has been rarely observed in gamasid mites, we briefly discuss its possible origins and consequences.

    Odontanthias randalli n. sp., a new anthiine fish (Serranidae: Anthiinae) from Indonesia

    White, William T. .
    8页
    查看更多>>摘要：Odontanthias randalli, a new species of anthiine serranid fish from southeastern Indonesia, is described, bringing the number of known species in the genus to 14. The new species is clearly distinguished from other members of the genus by the following combination of characters: dorsal-fin soft rays 16-17, lateral-line scales 37 to 39, 3(rd) dorsal spine longest, 3(rd) dorsal-fin soft ray the only filamentous dorsal-fin ray, caudal fin lunate with extremely long filamentous lobes, depth of body 2.2 to 2. 5 in SL, vomerine-tooth patch arrowhead shaped, and body pinkish with bright yellow spots on upper half and four pale pink blotches below dorsal-fin base. The new species is compared with other members of the genus.

    Revision of the genus Glyptoxanthus A. Milne-Edwards, 1879, and establishment of Glyptoxanthinae nov. subfam. (Crustacea: Decapoda: Brachyura: Xanthidae)

    查看更多>>摘要：The xanthid genus Glyptoxanthus A. Milne-Edwards, 1879, known from the tropical eastern Pacific, western and eastern Atlantic, and the Red Sea, is revised as part of an ongoing revision of the subfamily Euxanthinae Alcock, 1898. Analysis of morphological characters shows that Glyptoxanthus must be excluded from the subfamily Euxanthinae and placed in a distinct subfamily, Glyptoxanthinae nov. subfam. The new subfamily has affinities to Euxanthinae, Actaeinae Alcock, 1898, and Zalasiinae Serene, 1968,but it is distinguished from these by a suite of characters in the thoracic sternum, third maxillipeds, epistome, chelipeds, and male abdomen and gonopods. All the included species are re-diagnosed, with additional comments and updates on their biologyand distribution. In an effort to stabilize the taxonomy of the genus and some of its species, neotypes were selected for G. erosus (Stimpson, 1859) (type species), G. labyrinthicus (Stimpson, 1860), and G. meandricus (Lockington, 1877). A key to the genus is included.

    A new Colombian species in the milliped genus Psammodesmus, symbiotic host for bryophytes (Polydesmida: Platyrhacidae)

    查看更多>>摘要：The name Psammodesmus bryophorus is proposed for an ornate platyrhacid milliped discovered in a transitional Andean-Pacific montane rainforest in Narifio Department, Colombia. This species is remarkable for being the first milliped known to be host ofectocommensal mosses (10 species belonging to 5 families including especially Pilotrichaceae and Lejeu-neaceae) that grow on the milliped's dorsum The species is likewise of interest in that the male genitalia are similar to those of the Ecuadorian Psammodesmus fasciolatus Silvestri, while peripheral structures differ in a number of details. Both species are described and illustrated from type material. The effect of this situation on future conduct of platyrhacid taxonomy is highlighted.

    查看更多>>摘要：The examination of the holotype of Anolis baccatus Bocourt 1873 revealed that it is a representative of A. carolinensis Voigt 1832 and, therefore, this name is synonymized with the latter epithet.

    Misconceptions about the taxonomy and distribution of Caiman crocodilus chiapasius and C. crocodilus fuscus (Reptilia: Crocodylia: Alligatoridae)

    查看更多>>摘要：Four subspecies are currently recognized for the Spectacled Caiman, Caiman crocodilus (Linnaeus 1758): Caiman crocodilus fuscus (Cope 1868: Perosuchus fuscus), described from a single specimen from the Magdalena River, Colombia; C. c. chiapasius (Bocourt 1876: Alligator chiapasius), described from the Tonala Valley, Chiapas, Mexico; C. c. apaporiensis (Medem 1955) from the upper Apaporis River, Colombia; and, C. c. crocodilus (Linnaeus 1758: Lacerta crocodilus), named for the species originally described (Smith & Smith 1977; Busack & Pandya 2001). Caiman yacare was previously considered to be a fifth subspecies (i.e., C. c. yacare), but it is now generally accepted that it is a full species (King & Burke 1989), and is no longer treated as a subspecies (Velasco & Ayarzaguena 2010). There is some confusion about the current distributions of C. c. chiapasius and C c. fuscus, and although some works have attempted to clarify this situation (Busack & Pandya 2001), the confusion still remains (i.e., Rueda-Almonacid et al. 2007; Velasco & Ayarzaguena 2010). Here, we present a brief review of the taxonomic status of caiman subspecies, and its implications for their distributions.
