The new genus is proposed based on the total loss of sexual dimorphism in the P3 and P4 exopods, and the sexual dimorphism in P2 exopod. Fiersiphontina is highly adapted to the littoral interstitial habitat of coral sandy beaches, and is related to Laophontina Norman & T. Scott, 1905, Wellsiphontina Fiers, 1991 and Spiniferaphonte Gheerardyn & Fiers, 2007. The shared characteristics that indicate a strong affinity of Fiersiphontina toSpiniferaphonte are the robust, dorsally bent, and strongly sclerotised caudal seta V and the morphology of the genital field. The phylogenetic relationship of Spiniferaphonte and Fiersiphontina is also suggested by the analysis of the last ontogeneticphases of the species of the two genera. We re-describe here the adults of both sexes, describe the last three copepodid stages of Fiersiphontina sensillata (Wells & Rao, 1987) comb, nov., and provide notes on the biogeography of the four related genera,and on the ecology of Fiersiphontina and Spiniferaphonte.

    On the species identities of a complex Liolaemus fauna from the Altiplano and Atacama Desert: insights on Liolaemus stolzmanni, L, reichei, L. jamesi pachecoi, and L. poconchilensis (Squamata: Liolaemidae)

This evolutionary complexity has puzzled systematists and taxonomists since the first species were described more than 150 years ago. Within this lineage, the Andean Liolaemus faunas have proven to be a major challenge for herpetologists. Therefore, intense research is needed in this area to clarify long-standing problems. After more than a century of taxonomic confusion, the identity of Liolaemus stolzmanni (Steindachner, 1891) is here restored as the name that must be applied to the lizards widely known as Phrynosaura (= Liolaemus) reichei Werner, 1907 from the low to mid-elevation deserts of Tarapaca, Chile. Since 1966, the name L. stolzmanni has been erroneously assigned to populations of Liolaemus from the high Andes of the Chile-Bolivia borderlands which, according to observations presented in this study, correspond to Liolaemus pachecoi Laurent, 1995. A lectotype and allotype for L. stolzmanni are designated and the type locality for L. stolzmanni (= L. reichei) is emended to "Deserts of Iquique, Tarapaca Region, Chile". Furthermore, the recognition of L. pachecoi as a species distinct from L. jamesi is supported by mtDNA sequence divergence data despite the inconclusive meristic and morphometric data. In summary, I conclude that (/) the Chilean L. reichei is a synonym of L. stolzmanni, and hence, that L. stolzmanni is a species endemic to Chile, not an element of the fauna of present-day Peru and that (ii) the Chilean Altiplano populations currently recognized as L. stolzmanni are L. pachecoi, a species hitherto known only from Bolivia. Also, I report the first confirmed specimens of L. poconchilensis from Peru, a species previously known only from Chile and confused with L. reichei.

    New species of small, bathypelagic calanoid copepods from the Arctic Ocean: Brodskius arcticus sp. nov. (Tharybidae) and three new species of Pertsovius gen. nov. (Discoidae)

(family Discoidae Gordejeva, 1975) are described from deep waters of the Arctic Canada Basin. The female of Brodskius arcticus differs from five of the other six known species of this genus in the absence of rostral filaments, the lack of which it shares with B. abyssalis Markhaseva & Schulz, 2007. This new species differs from B. abyssalis in having two very short outer proximal spines at the distal segment of the fifth swimming legs (P5). The length of these spines is less than half the width of the segment, whereas in B. abyssalis they are longer than the width of the segment. The new genus Pertsovius is created here for a group of seven species within the family Discoidae which have one-segmented endopods of P2-P4. In contrast, the other genera of this family have three-segmented endopods of P2-P4. The three new species of Pertsovius differ from each other in the appearance of the genital field, and in the number of outer border spines on the distal exopodal segment of P2. In Pertsovius tridentatus sp. nov. this segment bears three external spines on both left and right P2. The left P2 of P. heterodentatus sp. nov. has three spines, while the right P2 bears two spines only. The distal segments of both left and right P2 of P. serratus sp. nov. have two external spines, but the proximal part of the external margin on the left P2 bears three relatively large denticles. The distal exopodal segments of P2 of the other four species here transferred to the genus Pertsovius are smooth with no external spines or denticles, but each bears two outer border spines.

    查看更多>>摘要：A new genus and new species of pilumnid crab is described from marine encrusting communities in Singapore. Leelumnus gen. nov. is morphologically similar to Latopilumnus Tiirkay & Schuhmacher, 1985, and Aniptumnus Ng, 2002, in the general shape of thecarapace, chelipeds, ambulatory legs and morphology of the male thoracic sternum, but can be distinguished by the morphologies of the front and anterolateral margin of the carapace, as well as the unique structure of the male first gonopod. Only the type species, L. radium sp. nov. is currently assigned to the new genus.

    查看更多>>摘要：Proceratophrys renalis (Fig. 1A) was recently revalidated (Prado & Pombal 2008). This frog species comprises a population previously recognized as P. boiei. It occurs in Atlantic forest from Paraiba to south of Bahia State, and in the interior of Brazil, close to transitions between Cerrado and Caatinga biomes, including Jequitinhonha river basin in Minas Gerais State (Prado & Pombal 2008). Anuran advertisement calls are species-specific, and bioacoustic analyses constitute an important character for species delimitation (Duellman & Trueb 1986).
