DOI: 10.3897/zookeys.1158.98868

Authors: Paul C. Southgate, Thane A. Militz

Abstract: Multivariate approaches to morphological study of shell form have rarely been applied to cowries (Gastropoda: Cypraeidae) with preference, instead, for comparing formulaic notations of shell form that report averages (i.e., means) for key morphometrics such as shell dimensions, their ratios, and counts of apertural teeth. Although widely applied, the “shell formula” does not account for variation among individuals or support statistical comparison between taxa. This study applied a multivariate approach to analyse shell form within the four accepted subspecies of the cowrie, Umbilia armeniaca (Verco, 1912) and included a previously unstudied, and most northerly, population of U. armeniaca from Lancelin, Western Australia. Multivariate analyses readily separated the recognised subspecies of U. armeniaca (U. a. armeniaca, U. a. diprotodon, U. a. clarksoni and U. a. andreyi), but did not separate the Lancelin population from U. a. andreyi, indicating that the former represents a northward extension of U. a. andreyi that is not morphometrically distinguishable. These results provide improved understanding of infraspecific differences in shell form of U. armeniaca across its broad distribution, and demonstrate the utility of multivariate morphometric methods for statistical comparison of shell form between taxa. This approach is complimentary to existing research practices and has broad potential application in future morphometric studies of both extant and fossil taxa within the family Cypraeidae.

Description of a new species of Membranobalanus (Crustacea, Cirripedia) from southern Australia https://zookeys.pensoft.net/article/35421/ ZooKeys 873: 25-42

DOI: 10.3897/zookeys.873.35421

Authors: Andrew M. Hosie, Jane Fromont, Kylie Munyard, Diana S. Jones

Abstract: A new species of sponge-inhabiting barnacle, Membranobalanus porphyrophilus sp. nov., is described herein. This species can be distinguished from all other congeners by a combination of characters, in particular by the shapes of the tergum and scutum and the armament of the cirri. COI sequence data from the type specimens have been lodged with GenBank and a morphological key to the species of Membranobalanus is provided to aid future research. The host of the new species is the southern Australian endemic demosponge Spheciospongia purpurea. The new species of barnacle is thought to be host species specific.

Conservation systematics of the shield-backed trapdoor spiders of the nigrum-group (Mygalomorphae, Idiopidae, Idiosoma): integrative taxonomy reveals a diverse and threatened fauna from south-western Australia https://zookeys.pensoft.net/article/24397/ ZooKeys 756: 1-121

DOI: 10.3897/zookeys.756.24397

Authors: Michael G. Rix, Joel A. Huey, Steven J.B. Cooper, Andrew D. Austin, Mark S. Harvey

Abstract: The aganippine shield-backed trapdoor spiders of the monophyletic nigrum-group of Idiosoma Ausserer s. l. are revised, and 15 new species are described from Western Australia and the Eyre Peninsula of South Australia: I. arenaceum Rix & Harvey, sp. n., I. corrugatum Rix & Harvey, sp. n., I. clypeatum Rix & Harvey, sp. n., I. dandaragan Rix & Harvey, sp. n., I. formosum Rix & Harvey, sp. n., I. gardneri Rix & Harvey, sp. n., I. gutharuka Rix & Harvey, sp. n., I. incomptum Rix & Harvey, sp. n., I. intermedium Rix & Harvey, sp. n., I. jarrah Rix & Harvey, sp. n., I. kopejtkaorum Rix & Harvey, sp. n., I. kwongan Rix & Harvey, sp. n., I. mcclementsorum Rix & Harvey, sp. n., I. mcnamarai Rix & Harvey, sp. n., and I. schoknechtorum Rix & Harvey, sp. n. Two previously described species from south-western Western Australia, I. nigrum Main, 1952 and I. sigillatum (O. P.-Cambridge, 1870), are re-illustrated and re-diagnosed, and complementary molecular data for 14 species and seven genes are analysed with Bayesian methods. Members of the nigrum-group are of long-standing conservation significance, and I. nigrum is the only spider in Australia to be afforded threatened species status under both State and Commonwealth legislation. Two other species, I. formosum Rix & Harvey, sp. n. and I. kopejtkaorum Rix & Harvey, sp. n., are also formally listed as Endangered under Western Australian State legislation. Here we significantly relimit I. nigrum to include only those populations from the central and central-western Wheatbelt bioregion, and further document the known diversity and conservation status of all known species.

The spider family Selenopidae (Arachnida, Araneae) in Australia and Asia https://zookeys.pensoft.net/article/2353/ ZooKeys 99: 1-103

DOI: 10.3897/zookeys.99.723

Authors: Sarah Crews, Mark Harvey

Abstract: The spider family Selenopidae Simon occurs worldwide in tropical and subtropical regions, currently containing nearly 200 species in five genera. We relimit and revise the family to include four new genera and 27 new species from Australia and Asia. The family Selenopidae is redefined, as are the genera Anyphops Benoit, Garcorops Corronca, Hovops Benoit, Selenops Latreille, and Siamspinops Dankittipakul and Corronca, to accommodate the new genera and to correct previous errors in the definition. The species of Selenops that occur throughout India and China are also reviewed. Three species occur in China: S. bursarius Karsch, also known from Japan, Korea and Taiwan, S. ollarius Zhu, Sha, and Chen, and S. radiatus Latreille, the type of the genus and most widespread selenopid. Selenops cordatus Zhu, Sha, and Chen is recognized as a junior synonym of S. radiatus, syn. n. Amamanganops gen. n. is monotypic, with A. baginawa sp. n., and is known only from the Philippine island of Mindoro. Godumops gen. n. is monotypic, with G. careus sp. n., and is known only from Papua New Guinea. Karaops gen. n. occurs throughout Australia and has 24 species: K. australiensis (L. Koch) comb. n., K. gangarie sp. n., K. monteithi sp. n., K. alanlongbottomi sp. n., K. keithlongbottomi sp. n., K. larryoo sp. n., K. jarrit sp. n., K. marrayagong sp. n., K. raveni sp. n., K. badgeradda sp. n., K. burbidgei sp. n., K. karrawarla sp. n., K. julianneae sp. n., K. martamarta sp. n., K. manaayn sp. n., K. vadlaadambara sp. n., K. pilkingtoni sp. n., K. deserticola sp. n., K. ngarutjaranya sp. n., K. francesae sp. n., K. toolbrunup sp. n., the type species K. ellenae sp. n., K. jenniferae sp. n., and K. dawara sp. n. The genus Makdiops gen. n. contains five species from India and Nepal: M. agumbensis (Tikader), comb. n., the type of the genus M. mahishasura sp. n., M. montigenus (Simon), comb. n., M. nilgirensis (Reimoser) comb. n., and M. shiva sp. n. The genus Pakawops gen. n. is monotypic and contains P. formosanus (Kayashima) comb. n. known only from Taiwan. Finally, Selenops aculeatus Simon is transferred to the genus Siamspinops, forming the new combination S. aculeatus (Simon) comb. n. The distribution and diversity of the Australasian selenopid fauna is discussed. Keys are provided to all of the selenopid genera and to the species of Karaops and Makdiops.

Eight new species of Macvicaria Gibson and Bray, 1982 (Digenea: Opecoelidae) from temperate marine fishes of Australia https://zookeys.pensoft.net/article/1928/ ZooKeys 1: 23-58

DOI: 10.3897/zookeys.1.8

Authors: Thelma Aken’Ova, Thomas Cribb, Rodney Bray

Abstract: Nine morphologically distinct species of Macvicaria Gibson & Bray, 1982 were recovered from six families, ten genera and twelve species of marine fishes in the waters off the coast of Queensland, Western Australia and South Australia: M. shotteri n. sp. in Apogon fasciatus (type-host), Sillaginodes punctatus and Sillago bassensis from Moreton Bay (type-locality), off southern Western Australia and off Kangaroo Island, South Australia; M. mekistomorphe n. sp. in Sillago maculata from Moreton Bay; M. mutovitellina n. sp. in Dactylophora nigricans from off southern Western Australia; M. flexuomeatus n. sp. in Goniistius gibbosus (type-host) and Cheilodactylus rubrolabiatus from southern Western Australia; M. vitellocopiosa n. sp. in Sillaginodes punctatus from off Kangaroo Island, South Australia; M. dextrocaula n. sp. in Notolabrus parilus (type-host) and N. fucicola (Richardson) (Labridae) from off southern Western Australia (type-locality) and Kangaroo Island, South Australia; M. heronensis Bray & Cribb, 1989 in Trachinotus coppingeri off Stradbroke Island, Queensland; M. adomeae n. sp. in Sillaginodes punctatus off Kangaroo Island, South Australia; M. kingscotensis n. sp. in Neoodax balteatus (type-host) and Haletta semifasciata off Kangaroo Island, South Australia. We have used the following characters to distinguish between the species of Macvicaria: general body form; length/width ratio; size of cirrussac; length of forebody; post-testicular extent of caeca; egg size; and the position of the genital pore. Most of the species of Macvicaria showed interspecific differences in all of the characters enumerated, the most dramatic being in the position of the genital pore in one species. All 11 specimens recovered from 2 species of Notolabrus were found to have a dextral genital pore. This is the second report of amphitypy in the Opecoelidae. All of the host species, apart from Apogon fasciatus, are endemic to Australian or Australian and New Zealand waters. New combinations formed are: M. dactylopagri (Manter, 1954); M. deeghaensis (Gupta & Gupta, 1988); M. eleuthoronemae (Wang, Wang & Zhang, 1992); M. gerridis (Fischthal & Thomas 1970); M. hunghuaensis (Qiu & Li in Shen & Qiu, 1995); M. longicirrata (Manter, 1963); M. oligolecithosus (Wang, Wang & Zhang, 1992); M. synagris (Yamaguti, 1952).
