Dead Trees

Approximately 100 species of Lasioseius have beendescribed worldwide, yet only two species have been reported from Australia(L. boomsmai Womersley andL. queenslandicus Womersley). We recently identifiedboth of these species from rainforest canopy chemical knockdown collectionsand reared them from fungal sporocarps growing on dead trees and logs. We alsofound that species in the Lasioseius porulosus group,previously unreported from Australia, are often the most numerous predatorymites on the leaves of tropical rainforest trees and of tropical tree crops inQueensland. Herein, we provide new collection records, diagnoses andbiological information for the two previously known Australian species ofLasioseius; review the Australian members of theporulosus group; describe five new species(Lasioseius cuppa,L. quandong,L. traveni, L. wondjina andL. zaluckii); and present a key to the species ofLasioseius that inhabit rainforest leaves. One of the previous records ofL. queenslandicus is shown to represent a pantropicaltramp species,L. subterraneusChant (newly reported fromAustralia), and L. athiasae Nawar & Nasr is shown tobe a junior synonym ofL. queenslandicus.Gnorimus Chaudri, 1975, Indiraseius Dansehvar, 1987, andNeolaspina Halliday, 1995, are shown to be synonyms ofLasioseius.

Three New Species

Australian mites in the genus Asca were last reviewed in 1956 when the first three Australian species were described. We here provide diagnoses for those species, describe three new species (Asca macromela, A. grostali and A. mindi) from the leaves of rainforest trees, and report on the occurrence in Australia of a species described from New Zealand (A. porosa Wood) and of a cosmopolitan thelytokous species (A. garmani Hurlbutt). Keys to the eight species and the three species-groups they represent are provided. Examination of 13 266 leaves from 193 species of woody plants in eastern Australian forests indicated that Asca mites are abundant and diverse inhabitants of tropical rainforest canopies, but decline in both diversity and abundance with increasing latitude.

<p>The New Zealand Thomisidae (crab spiders) are represented in New Zealand by two subfamilies (Stephanopinae and Thomisinae) and were used as a model group to test two competing theories on the origins of the New Zealand spider fauna. The New Zealand thomisids are also given their first full taxonomic revision. The two origin models essentially represent species radiations following recent dispersal or ancient vicariance events. Modern distribution data suggested that the stephanopines are poor dispersers and may provide evidence demonstrating a long period of separation from Australia; while in contrast, thomisines are known to be excellent dispersers. Maximum Likelihood and Bayesian analyses of cytochrome c suboxidase subunit I (COI), 28S ribosomal RNA (28S), histone H3 (H3), NADH dehyrogenase 1 (ND1) data and a combined genetic dataset was undertaken. Results indicate New Zealand stephanopines and thomisines form distinct endemic groups separate from sampled Australian species and appear to have separated from them around 5-6 million years ago. Additionally, genetic data from this study showed i) colour variations are not indicative of cryptic species; ii) previously described species are genetically distinct; iii) several suspected new species are also genetically distinct; iv) the relatively recent establishment of two Australian stephanopines and the occurrence of similar COI haplotypes in disjunct locations suggest that the dispersal ability of stephanopines is greater than previously thought and that radiation following colonization from Australia is a plausible explanation for the current diversity of the New Zealand thomisid biota. The taxonomic revision raises the number of described species from eight to eleven based on a combination of morphological and genetic data. In the stephanopines, Bryantymella Gen. nov. is erected to contain the type species Bryantymella angularis (Urquhart, 1885) comb. nov. as well as B. angulata (Urquhart, 1885) comb. nov., B. thorini sp. nov. and B. brevirostris sp. nov. Two Australian species, Sidymella longipes (Koch, 1874) and S. trapezia (Koch, 1874), are also recorded for New Zealand. Sidymella benhami (Hogg, 1910) is considered to be a junior synonym of Bryantymella angulata (Urquhart, 1885). In the thomisines, all species are now included in the previously monotypic genus Cymbachina Bryant, 1933. The genus now encompasses the type species C. albobrunnea (Urquhart, 1893), C. ambara (Urquhart, 1885) comb. nov., C. albolimbata (L. Koch, 1893) comb. nov., C. sphaeroides (Urquhart, 1885) comb. nov. and D. urquharti sp. nov. Synema suteri Dahl, 1907 is regarded as a junior synonym of C. ambara (L. Koch 1893). All previously described species are redescribed to a modern standard and sexes for some species are described for the first time. Three new species are described. Photographs of adults and diagnostic genitalic characters are included, as are diagnostic keys and updated synonymic, geographic and biological information. Overall, this study indicates that New Zealand thomisids appear to have split from their Australian relatives some 5-6 million years ago and taken in concert with the recent establishment of two Australian stephanopine species, it appears that dispersal to New Zealand by Australian colonists and subsequent radiation into endemic New Zealand forms is a plausible explanation for the current state of the fauna. Genetic and morphological data are mutually supporting and in concert have helped inform the first taxonomic revision ever undertaken for this family in New Zealand.</p>

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

In this paper, M. yanomami n. sp., from Brazilian Amazonia, Chaetacis bandeirante n. sp., from Central Brazil, and the males of M. gaujoni Simon, 1897 and M. ruschii (Mello-Leitão, 1945) n. comb. , respectively from Ecuador and Brazil, are described and illustrated for the first time. An ontogenetic series of the last development stages of both sexes of Micrathena excavata (C. L. Koch, 1836) is illustrated and briefly described. Adult females are larger and have longer legs and larger abdomens than adult males. Probably females undergo at least one additional moult before adulthood, compared to males. Micrathena ornata Mello-Leitão, 1932 is considered a junior synonym of M. plana (C. L. Koch, 1836), and M. mastonota Mello-Leitão 1940 is synonymized with M. horrida (Taczanowski, 1873). Acrosoma ruschii Mello-Leitão, 1945 is revalidated, transferred to Micrathena and considered a senior synonym of M. cicuta Gonzaga & Santos, 2004. Chaetacis necopinata (Chickering, 1960) is recorded for Brazil for the first time. Chaetacis incisa (Walckenaer, 1841) is considered a nomen dubium.

The genus Agrotera Schrank, 1802 is revised for Australia and the generic definition is refined based on the male genitalia. The genera Leucinodella Strand, 1918 stat. rev. with L. leucostola (Hampson, 1896) comb. nov., Nistra Walker, 1859 stat. rev. with N. coelatalis Walker, 1859 comb. rev., Sagariphora Meyrick, 1894 stat. rev. with S. magnificalis (Hampson, 1893) comb. nov., and Tetracona Meyrick, 1884 stat. rev. with T. amathealis (Walker, 1859) comb. rev. and T. pictalis Warren, 1896 comb. rev. are removed from synonymy with Agrotera, as they lack the synapomorphies of Agrotera. Two new species, Agrotera genuflexa sp. nov. from Northern Territory, Queensland and New South Wales, and A. longitabulata sp. nov. from Queensland, are described. The taxonomic status of the Australian species of Agrotera is discussed, and a key to all species, based on males, is provided. The adults and genitalia of the new species and some related species are figured.

A study has been made of the Australian species of Aponomma and Amblyomma (Ixodoidea). Nine species of Aponomma were determined, namely A. trachysauri, A. hydrosauri, A. auruginans, A. decorosum, A. simplex, A. trimuculatum, A. tachyglossi, A, tropicum, and A. pulchrum, the last three species being new. Two previously described species, namely A. quadratum and A. ecinctum, were recognized among the material available for study. A detailed description given of each species together with essential figures. Keys to the males, females, and nymphs are included. Twelve species of Amblyomma were seen. Species previously described included A. moreliae, A. limbatum, A. albolimbatum, A. triguttatum, A. australiense, and A. papuanu. A. postoculatum and A. helvolum were not recognized among the material available for study. A. papuana is recorded from Australia for the first time. Four new species, namely A. sternne, A. echidnae, A. macropi, and A. moyi, are described. Keys to the males and females are given.
