The suborder Fulgoromorpha, highly diverse and speciose today, was a minor component of the Cicadomorpha-dominant hemipteran fauna of the Queensland Triassic known only from five tegmen specimens of three species in three genera of the extinct family Surijokocixiidae: Tricrosbia minuta Evans, 1971, and Crosbixius carsburgi gen. et sp. nov., from the Late Triassic (Norian) Mount Crosby Formation of the Ipswich Coal Measures, and Karesmina punicea gen. et sp. nov. from the Middle Triassic (Anisian) Esk Formation. The Surijokocixiidae are otherwise known from four Permian genera from Russia and unnamed Triassic species from Kyrgyzstan and China. Tricrosbia Evans, 1971, is distinguished from other genera of the family by its simple MP1+2, and the very shallow fork of CuA. Crosbixius is similar to the Permian Surijokocixius Becker-Migdisova, but differs in the costal space of equal width along its entire length, the more basal fork of ScP+RA and RP, and mp-cu running between MP and CuA1 rather than MP3+4 and CuA1. Karesmina is distinguished by its larger size (tegmen length 9 mm, < 6 mm in the others), backwardly inclined ir, and peculiar structure of RP and MP1+2. Tricrosbia and Crosbixius were the last of the Surijokocixiidae which were extinct by the end of the Triassic, succeeded in the Jurassic by a more diverse and modern looking fulgoromorph fauna, dominated by numerous species of the extinct Fulgoridiidae. Confirmation of the presence of the Surijokocixiidae in the Mount Crosby Formation adds another family to the Ipswich Coal Measures hemipteran fauna, a transition insect fauna typical of the Triassic, with a mix of survivors from the Permian which did not last beyond the Triassic (Dunstaniidae, Scytinopteridae, Surijokocixiidae) or Jurassic (Dysmorphoptilidae), peculiar Triassic endemics (Chiliocyclidae, Mesogereonidae, Ipsviciidae), the newly emerged Hylicellidae which survived until the Cretaceous, and lastly more modern forms, Archijassidae, the earliest record of the extant Membracoidea, and Tettigarctidae, the hairy cicadas, which still exist today.

Pallidelix Iredale, 1933 is revised on the basis of conchological and anatomical morphology. Nine new species Pallidelix lonesome sp. nov., P. expeditiana sp. nov., P. potteri sp. nov., P. staricki sp. nov., P. lambkinae sp. nov., P. moffatt sp. nov., P. grandis sp. nov., P. minerva sp. nov. and P. zamia sp. nov. are described. Penial pilaster patterns and shell sculpture were considered significant species delimiting characters. A key to species is presented. Two species are shown to have relatively widespread distributions while the majority have small circumscribed distributions in scattered and isolated patches of vine thicket. Two species placed in Pallidelix by Stanisic et al. (2010) from south-eastern Queensland, viz. H. bennetti Brazier 1872 and P. chinchilla Stanisic, 2010 are herein excluded from the genus. As part of this revision the taxonomic status of the problematic Helix expeditionis Cox, 1868 (considered a synonym of P. greenhilli by Stanisic et al. 2010) is also discussed.

The family Pisauridae for Australia and the western Pacific is revised. The Australian fauna includes Dolomedes, Megadolomedes, Hygropoda, Perenethis, Dendrolycosa and Inola along with 3 new genera, Tasmomedes, gen. nov., Ornodolomedes, gen. nov., and Mangromedes, gen. nov. Dolomedes in the region includes 16 species. four of which are known – Dolomedes facetus L. Koch, 1876, Dolomedes albicomus L. Koch, 1867, Dolomedes instabilis L. Koch, 1876 and Dolomedes flaminius L. Koch, 1867– plus 9 that are new: Dolomedes vicque sp. nov. from Victoria to Queensland, Dolomedes briangreenei sp. nov. and Dolomedes venmani sp. nov. in New South Wales and Queensland, Dolomedes alexandri sp. nov., from the Australian Capital Territory, Dolomedes pedder sp. nov. and Dolomedes lizturnerae sp. nov. from Tasmania, Dolomedes wollemi sp. nov. from New South Wales, Dolomedes mankorlod sp. nov. from the Northern Territory, Dolomedes karijini sp. nov. from Western Australia. Of those, Dolomedes flaminius remains the most perplexing as no further material has been located from the Brisbane area from which it putatively came prior to 1867; the locality is presumed wrong. Dolomedes stilatus Karsch, 1878 is a synonym of Perenethis venusta L. Koch, 1878. Dolomedes habilis Hogg, 1906 is a junior synonym of Dolomedes instabilis. Dolomedes chroesus Strand, 1911 is removed from the fauna of Australia because of misidentifications. The newly rediscovered Dolomedes eberhardarum Strand, 1913 from Tasmania and Victoria is transferred to the new genus, Tasmomedes. A new species of Megadolomedes, Megadolomedes johndouglasi is described from Tasmania and Victoria; Megadolomedes trux Lamb, 1911 is restored as the northern relative of Megadolomedes australianus (L. Koch, 1865); Megadolomedes nord sp. nov. is described from Cape York. Nilus kochi Roewer, 1951 is rediscovered in mangroves in Queensland and with a new species from the Northern Territory (Mangromedes porusus sp. nov.), is transferred to Mangromedes, gen. nov. A new genus, Ornodolomedes, is described in which the spiders hunt freely at night on leaves on rainforest and closed eucalypt forest; the spiders have bold carapace and abdominal patterns. The genus includes 10 new species. from Queensland, Ornodolomedes mickfanningi sp. nov., Ornodolomedes benrevelli sp. nov., Ornodolomedes gorenpul sp. nov., Ornodolomedes yalangi sp. nov., Ornodolomedes nebulosus sp. nov., Ornodolomedes xypee sp. nov. and Ornodolomedes marshi sp. nov.; Ornodolomedes staricki sp. nov. from Victoria; from Western Australia, Ornodolomedes nicholsoni sp. nov., and Ornodolomedes southcotti sp. nov. from South Australia. In Dendrolycosa, the male of Dendrolycosa icadia (L. Koch, 1878) is described for the first time and one new species, Dendrolycosa kakadu sp. nov. is described from the Northern Territory. Dendrolycosa yuka Jäger, 2011 is considered African, not Australian. The male of Hygropoda lineata (Thorell, 1881) is described for the first time. The

The genus Proablepharus currently contains five species (P. barrylyoni, P. kinghorni, P. naranjicaudus, P. reginae and P. tenuis). Morphologically, these are readily separated into two groups: the small, almost patternless species (P. reginae and P. tenuis) and the larger, striped species (P. kinghorni, P. barrylyoni and P. naranjicaudus). We present genetic and morphological data to demonstrate that these two groups are generically distinct from each other. As P. reginae is the type species for Proablepharus, we erect a new genus, Austroablepharus gen. nov., for the kinghorni group and designate A. kinghorni as the type species.
probablepharus属目前包含5种(P. barrylyoni, P. kinghorni, P. naranjicaudus, P. reginae和P. tenuis)。在形态上,它们很容易被分为两类:小的,几乎没有图案的物种(P. reginae和P. tenuus)和大的,有条纹的物种(P. kinghorni, P. barrylyoni和P. naranjicaudus)。我们提出了遗传和形态学数据,以证明这两个群体在一般情况下彼此不同。由于P. reginae是Proablepharus的模式种,我们为kinghorni群建立了一个新属Austroablepharus gen. nov.,并指定a . kinghorni为模式种。

In general, sex-ratios in herbivorous gastropods show a strong female bias, particularly in the family Strombidae of the Indo-Pacific. Previous studies of Indo-Pacific strombs point to an underlying female bias in most species. However, the full spatial extent and potential mechanisms driving this phenomenon are currently unknown. Therefore, we studied two populations of Laevistrombus canarium Linne, 1758 over a four year period to explore sex-ratio bias and to investigate the underlying mechanisms. Furthermore, the current study investigated methods to test for sex-ratio bias in strombs where samples are limited and sampling is problematic We sampled individuals from two reefs in Far North Queensland, Australia, with different benthic compositions, despite their close proximity (approximately 4 km apart). In agreement with previous studies, we also found a strong bias towards females. This bias remained consistent across both locations and changes in benthic substrate. Our findings are consistent with models suggesting inherent genetic factors regulate natural patterns of sex imbalance in these strombs. These findings also suggest that there are as yet unidentified stromb life-history characteristics associated with the origin and maintenance of this phenomenon.

These findings also suggest that there are as yet unidentified stromb life-history characteristics associated with the origin and maintenance of this phenomenon.","PeriodicalId":35552,"journal":{"name":"Memoirs of the Queensland Museum","volume":"125 1","pages":"133-138"},"PeriodicalIF":0.0,"publicationDate":"2017-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80441025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
