The morphology of the two species of Australian freshwater assimineids is described in detail. A new genus and species of Assimineinae, Aviassiminea palitans, is named from freshwater springs in north Western Australia and the Northern Territory. Austroassiminea letha Solem et al., 1982 from coastal springs in south Western Australia is also described and the original anatomical account is corrected in several important details. This taxon is shown to be a member of the Omphalotropidinae and is the only other non-marine assimineid known from Australia. All of the described assimineid genus-group taxa are listed in an appendix, with an assessment of their status, and their known diagnostic characters.  相似文献

Two new species, Leicacandona pinkajartinyi sp. nov. and L. jula sp. nov., are described from the Great Sandy Desert, Western Australia. Both species have reduced posterior claws on the caudal ramus, but differ in carapace shape and the length of setae and number of segments on the second and third thoracopods. A cladistic tree based on 27 morphological characters and a tree based on geographic latitudes and longitudes of the localities where Leicacandona species have been collected so far were constructed. These two cladograms do not correspond completely, although some similarities exist. The results obtained here agree with those obtained for some other subterranean animals in Australia, and they are understood as independent colonizations of subterranean waters by a couple of widespread surface water species.  相似文献

Two new species of the parabathynellid genus Notobathynella Schminke, 1973 Schminke, HK. 1973. Evolution, System und Verbreitungsgeschichte der Familie Parabathynellidae (Bathynellacea, Malacostraca)Akad Wiss Lit Mainz, Math-Naturwiss Klasse, Mikrofauna Meeresbodens, 24: 1192.  [Google Scholar] are described from Australia: N. octocamura sp. nov. and N. pentatrichion sp. nov. Notobathynella octocamura sp. nov. has eight claws on the distal endite of the maxillule, a character that is unique in the Parabathynellidae. It is also the first species of the genus with the following characters: five setae on the terminal segment of antenna, 26–28 teeth on labrum, 31 setae on maxilla, a three-segmented exopod on thoracopod I, five-segmented exopods on thoracopods IV and V, three setae and two claws on the fourth endopodal segment of thoracopods I to IV, and six setae on the uropodal exopod. This species also has a unique setal formula for some thoracopods. Notobathynella pentatrichion sp. nov. is unique in the genus with five setae on the uropodal exopod and, like N. octocamura sp. nov., has a one- or two-segmented exopod on thoracopod I, a four- or five-segmented exopod of thoracopod V, and three setae and two claws in the four segments of the endopod of thoracopods II to IV. The two new species extend the distribution of Bathynellacea in Australia and are the first species to be described from Queensland.  相似文献

Two new species of the parabathynellid genus Chilibathynella Noodt, 1963 Noodt, W. 1963. Estudios sobre Crustaceos de aguas subterraneas, III. Crustacea Syncarida de Chile Central. Investig Zool Chilenas, 10: 151167.  [Google Scholar] are described from Australia. Chilibathynella joshuai sp. nov. has a unique combination of morphological characters, which includes five-segmented antenna, no epipodite on thoracopod I, two setae on the endopod of the male thoracopod VIII, homonomous row of 17 spines on uropodal sympod, uropodal exopod with four distal spines and a flat anal operculum. Chilibathynella digitus sp. nov. has two exclusive characters: six teeth on the pars incisiva of the mandible and a large, elongated digitiform protuberance (resembling a finger) on the basipod of male thoracopod VIII. The species also displays a unique combination of morphological characters, which includes five-segmented antenna, no epipodite on thoracopod I, no outer marginal seta on the first and second segments of the endopod of thoracopod I to VII, two setae on the endopod of the male thoracopod VIII, homonomous row of 12 spines on uropodal sympod, uropodal exopod with three distal spines and an unprotruded anal operculum. The two new species extend the distribution of the Chilibathynella genus in Australia from Victoria to New South Wales. A new genus and species of the family Parabathynellidae, Onychobathynella bifurcata gen. nov. sp. nov., is described from New South Wales, Australia. The new genus displays an evolutionary novelty, for Parabathynellidae and the entire group of Bathynellacea: the antennule, antenna, thoracopods, pleopod I and uropod have setae that are strong, thick, short, barbed and claw-like. This new genus is the first in the family without smooth setae on the antennule and antenna. The new genus also has a combination of characters that makes it unique in Parabathynellidae: the antennule is eight-segmented like Octobathynella Camacho and Hancock, 2010 Camacho, AI and Hancock, P. 2010. A new record of Parabathynellidae (Crustacea, Bathynellacea) in Australia: a new genus and species from New South Wales. J Nat Hist, 44(17–18): 10811094. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]; the antenna is five-segmented; the labrum has 20 teeth; the exopod of thoracopod I to VII has only one segment; the endopod lacks dorsal setae on the first segment and the epipod is absent from thoracopod I; first pleopods are present and resemble two barbed curved claws; there are 18 bifid spines on the sympod, two spines and four setae resembling strong barbed claws on the endopod and six robust setae on the exopod of the uropod.  相似文献

通过对前往澳大利亚班布里海豚探索中心的访客进行调研,运用因子分析、K-means聚类分析、方差分析等定量方法,分析游客对在野外生境中接触海豚的风险感知程度及差异性。通过探索性因子分析,共识别和提取野生动物旅游风险感知量表的3个维度:体验质量风险、舒适性风险和身体安全风险。受访者感知程度最强为体验质量因子,其次为舒适性,最后为身体安全。运用K-means聚类分析方法,依据量表均值得分,将受访者分为3类:弱风险感知、强风险感知和中等风险感知,而样本总体对接触海豚风险感知程度归属为弱风险感知,认为接触海豚是相对安全的活动。通过独立样本t检验和方差分析,对比不同游客特征对野生动物旅游风险感知的差异性。结果发现,人口社会学特征中,除性别外,不同年龄、收入和家庭状况在风险感知程度上均存在显著性差异;旅游行为中,旅游经历、旅行同伴、消费额和停留时间对风险感知具有显著性差异,信息来源途径无显著性差异;满意度和重游意愿对风险感知都具有显著性差异。  相似文献

The genus Allotisis Pascoe is revised. Diagnosis of Allotisis is given, three known species are redescribed and six species are described as new : A. repleta, A. notabilis, A. rara, A. labyrinthina, A. monteithi and A. furva. All species are from Australia. Thoris moerens Blackburn is synonymous with A. unifasciata. A key to the nine species is provided. Phylogenetic analysis suggests that this genus be divided into two species groups, monteithi-group and unifasciata-group. Several subgroups are also identified. Biogeographic distribution of these species groups and subgroups is discussed.  相似文献

Two new genera are described for some species of Cryptocephalinae from the Australasian region. Melatia is erected for 29 species hitherto described in Cadmus Erichson, Cryptocephalus Geoffroy and Lachnabothra Saunders, from New Guinea and nearby islands; Ditropidella for four species described in Coenobius Suffrian and Ditropidus Erichson, from southern Australia.  相似文献

Two new genera Monitus gen.nov. and Cuckoldillo gen.nov., a new species of each of Scyphax, Rhyscotus, Filippinodillo, Merulana, Myrmecodillo, and three new species of Acanthodillo are described from Australia. The unavailability of the name Pseudodiploexochus and the confusion concerning the diagnoses of the genera Merulana Budde-Lund and Cubaris Brandt is noted. The synonomy of Merulana and Pyrgoniscus is discussed.  相似文献
