    In the century since the description of the orthoclad genus Paratrichocladius Santos-Abreu (Diptera: Chironomidae), separation in any life stage from the cosmopolitan, diverse Cricotopus Wulp has been problematic. Molecular analysis reveals the presence of two species in Australia that conform in morphology to Paratrichocladius and which form a well-supported clade including Paratrichocladius micans (Kieffer) from Africa and a distinct southern African larva. This clade clusters with taxa allied with Cricotopus albitibia (Walker), in turn nested within all other sampled Australian Cricotopus. Relevant nodes strongly support Cricotopus as nonmonophyletic without inclusion of Paratrichocladius. We synonymize Paratrichocladius with Cricotopus syn.n, treating Paratrichocladius as a subgenus. Cricotopus (Paratrichocladius) australiensis Cranston sp.n. is described for Trichocladius pluriserialis Freeman from Australia, which is not the same species under that name in New Zealand. Cricotopus (Paratrichocladius) bifenestrus Cranston sp.n. from Australia is described, also in all life stages. The many new combinations, listed in an Appendix, include three replacement names for new secondary homonyms, namely: Cricotopus (Paratrichocladius) sinobicinctus Cranston & Krosch nom.n. for Paratrichocladius bicinctus Fu, Sæther & Wang, Cricotopus draysoni Cranston & Krosch nom.n. for Cricotopus brevicornis Drayson, Krosch & Cranston, and Cricotopus (Paratrichocladius) sikhotealinus Makarchenko & Makarchenko nom.n. for Cricotopus orientalis Kieffer. We conclude with comments on wider issues in the taxonomy of Paratrichocladius, especially concerning New Zealand species

    Lines in the land: A review of evidence for eastern Australia's major biogeographical barriers to closed forest taxa

    The influence of climatic changes occurring since the late Miocene on Australia’s eastern mesic ecosystems has\ud received significant attention over the past 20 years. In particular, the impact of the dramatic shift from\ud widespread rainforest habitat to a much drier landscape in which closed forest refugia were dissected by open\ud woodland/savannah ecosystems has long been a focal point in Australian ecology and biogeography. Several\ud specific regions along the eastern coast have been identified previously as potentially representing major\ud biogeographical disjunctions for closed forest taxa. Initially, evidence stemmed from recognition of common zones\ud where avian species/subspecies distributions and/or floral communities were consistently separated, but the body\ud of work has since grown significantly with the rise of molecular phylogeographic tools and there is now a\ud significant literature base that discusses the drivers, processes and effects of these hypothesised major\ud biogeographical junctions (termed barriers). Here, we review the literature concerning eight major barriers\ud argued to have influenced closed forest taxa; namely, the Laura Basin, Black Mountain Corridor, Burdekin Gap,\ud Saint Lawrence Gap, Brisbane Valley Barrier, Hunter Valley Barrier, Southern Transition Zone and East\ud Gippsland Barrier. We synthesise reported phylogeographical patterns and the inferred timing of influence with\ud current climatic, vegetation and geological characteristics for each barrier to provide insights into regional\ud evolution and seek to elicit common trends. All eight putative biogeographical barriers are characterised\ud currently by lowland zones of drier, warmer, more open woodland and savannah habitat, with adjacent closed\ud forest habitats isolated to upland cool, wet refugia. Molecular divergence estimates suggest two pulses of\ud divergence, one in the early Miocene (~20–15 Mya) and a later one from the Pliocene–Pleistocene (~6–0.04 Mya).\ud We conclude with a prospectus for future research on the eastern Australian closed forests and highlight critical\ud issues for ongoing studies of biogeographical barriers worldwide

Larvae can be recognised by a combination of mandible with smooth outer and serrate inner surfaces, antenna length less than 90 µm, and AR less than 1.64. Adult specimens perfectly fit the descriptions of Freeman (1961) and Hergstrom (1974). A highly genetically divergent larval form is recognized from three specimens from the Castlereaigh River (Warrumbungles, NSW). These specimens do not cluster with other <i>C. annuliventris</i> (Krosch et al., submitted), but form a group unto themselves, and with some relationship to both <i>C. annuliventris</i> and <i>C.</i></p> <p> <i>tasmania</i>. On morphology these larvae key to <i>C. annuliventris</i>, but may be differentiated by the mandible pigment extending to the base with less strong contrast to the mid-brown head capsule, a narrow mola, a broad rounded median mentum tooth and second lateral mentum teeth no smaller than the first laterals.</p> <p> <i>C. annuliventris</i> is restricted to south-east Australian cool streams, often at elevation and shaded.

Pc 20–29 µm, A.s. 500–600 µm.</p> <p> <b>Etymology.</b> The name <i>parbicinctus</i> is likely a lapsus for intended <i>parabicinctus</i> (Hergstrom states in her description "Very similar to <i>bicinctus... "</i>). We see no reason to emend Hergstrom’s name and we recognise her as the sole author, validated here.</p> <p> <b>Remarks.</b> Adults of this species can be distinguished from all other Australian <i>Cricotopus</i> by the pale bands on the tibiae of all legs (this banding is easily visible to the naked eye). Pupae are recognised by absence of frontal setae, lacking PSB on segment III, 4 long l4 setae on VIII, and TII anterior to the narrow hook row bare. From the otherwise similar <i>C. acornis</i> it can be distinguished by the presence of a characteristic long, narrow, spinose thoracic horn. Larvae recognised only by a combination of the mandible with smooth outer and serrate inner margin and antenna length more than 90 µm.</p> <p> Although this species appears to be <i>" C. parbicinctus "</i> of Hergstrom (1974), she describes "tergite I, anterior parts of n, III, IV and V yellow in most specimens" and describes the larva as having "about 5 serrations on inner surface and with wrinkled outer surface". Her proposed holotype, now in A.N.l.C., has anterior and posterior pale bands on TII–VI, but TI is dark. Two of her proposed paratypes have vittae on the thorax and in fact belong to <i>C. hillmani</i> (q.v.). The species differs from the Palaearctic species <i>bicinctus</i> in colour of the thorax and abdomen and shape of genitalia of males, absence of PSB on segment III of pupa, and lack of crenulation on outer margin of mandible of larva (Hirvenoja 1973). A highly genetically divergent form is recognized from larvae and a single adult male from several locations throughout Queensland and New South Wales. This genetic form is reciprocally monophyletic to all other <i>C. parbicinctus</i> and branch lengths between the clades are substantial. Larvae of this divergent form may be separable from <i>C. parbicinctus</i> only by the extent of mandible pigment (extending to the external seta or beyond in the divergent form). More extensive sampling may reveal this taxon to be a true biological species; however, we consider it only as a form pending further work.</p> <p> <i>C. parbicinctus</i> is a widespread species, but represented in Western Australia only by one location in the southern hills and one in Tasmania, and seemingly absent from Northern Territory. Within its range it inhabits pristine to slow to stagnant, macrophyte-dominated and nutrient enriched waters.</p>Published as part of <i>Drayson, Nick, Cranston, Peter S. & Krosch, Matt N., 2015, Taxonomic review of the chironomid genus Cricotopus v. d.

They can be distinguished from <i>C. varicornis</i>, for which the leg pattern is not known, only by the pattern of tergal setation, and the spermathecal capsule shape, both of which features may be unreliable. Pupae are easily recognised by the dark adhesion marks on all abdominal segments. The frontal setae are present on the prefrons, tergites I and II essentially bare of spines or spinules, and mid-paraterga spinulose. From the otherwise similar <i>C. howensis</i>, it can be distinguished by the thoracic horn bearing apical/subapical small tubercles (Fig. 6 E). Larvae can be recognised by the mandible having a moderately elongate apical tooth, crenulate outer and smooth inner margin, antennal blade reaching apex of antenna with large Lauterborn organs, and especially, but not always, the presence of a small 7th lateral tooth on the mentum.</p> <p> As discussed below, Hergstrom (1974) included specimens of <i>C. hillmani</i> in her <i>" C. parbicinctus</i> ". A specimen in the A.N.I.C. collection was identified by Freeman as C. <i>annuliventris,</i> but the thorax, legs and abdomen clearly show it to belongs to <i>C. hillmani.</i></p> <p> <i>C. hillmani</i> is an essentially south-eastern Australian species (including Tasmania) with an anomalous record from far north Queensland. Records are all from rivers and creeks in good water health.</p>Published as part of <i>Drayson, Nick, Cranston, Peter S. & Krosch, Matt N., 2015, Taxonomic review of the chironomid genus Cricotopus v. d.

    An evaluation of infrared photography for detecting bloodstains on dark-coloured floor coverings commonly encountered at crime scenes

    No full text
    The ability to accurately detect bloodstains is fundamental to crime scene examination; however, traditional methods can be inadequate for use on many dark-coloured surfaces commonly encountered at scenes, such as fabrics and flooring. An alternative approach may be the use of infrared (IR) photography, which is known to be effective at detecting bloodstains on fabrics and some non-porous surfaces. However, a knowledge gap exists concerning the effectiveness of IR photography for detecting bloodstains on dark-coloured floor coverings. To address this, we used a paired sampling design to assess the performance of IR photography compared with tetramethylbenzidine (TMB) and luminol for detecting bloodstains on wool and nylon carpet, linoleum, vinyl, tile and laminate flooring. We also assessed whether IR imaging would detect a substance known to create false-positive reactions with TMB and luminol. Overall, our results supported IR photography as an effective, non-destructive method compared to TMB and luminol for detecting bloodstains on dark-coloured flooring, especially nylon carpet, tile, laminate and vinyl. Further, IR did not detect known false-positive samples on several surfaces. This research contributes to a growing body of literature concerning the forensic applications of IR photography and has significant operational implications for crime scene examiners.</p

A spelling as &lt;i&gt;albitarsus&lt;/i&gt; has been used, including on the labels of Hergstrom&rsquo;s type series: we consider this a lapsus.&lt;/p&gt; &lt;p&gt; &lt;b&gt;Remarks.&lt;/b&gt; Adults of this species can be distinguished from all other Australian &lt;i&gt;Cricotopus&lt;/i&gt; by leg colour, with dark femora, pale tibiae, and pale tarsomeres on mid- and hind legs. Pupae can be recognised by the frontal setae on the frons, the hyaline and non-spinose thoracic horn and regular anal macrosetae. Larvae cannot be recognised by a single feature, but by a combination of mandible with crenulate outer and smooth inner surface, mentum with 6 pairs of lateral teeth and the apices of the first lateral mental teeth posterior to the apex of the median tooth, plus the dark pigment restricted to the apical mandible only.&lt;/p&gt; &lt;p&gt; From Freeman's (1961) description of pinned Australian specimens, this species appears to be his &lt;i&gt;C. albitibia,&lt;/i&gt; although his description differs in having the AR as 1, i.e., much lower than the range of specimens measured in this study. Calculations of the antennal ratio from dried material is notoriously error-prone and we do not consider it significant. One male from Lake Monger, WA, labelled &quot; Cricotopus albitibia, det. P. Freeman&quot;, from the British Museum (B.M.1955-478, slide-mounted by P. S. Cranston) was studied. This, one of the six male specimens from the location given in Freeman's description, fits the description of &lt;i&gt;C. albitarsis&lt;/i&gt; above, with an AR of 1.5, as does the colour of five pinned specimens from the same locality also in A.N.I.C..&lt;/p&gt; &lt;p&gt; The type location of C. &lt;i&gt;albitibia&lt;/i&gt; is Sierra Leone in west Africa (Walker, 1848), but the species was redescribed by Lehmann (1979) from specimens from east Zaire (=D.R. Congo). Lehmann's species as re-described differs from our Australian material in the following: adult leg pattern, with &lt;i&gt;C. albitibia&lt;/i&gt; having pale bands on all legs; adult thorax pattern, with &lt;i&gt;C. albitibia&lt;/i&gt; having brown vittae or &quot;mesonotal stripes&quot; and the pupal thoracic horn, that of &lt;i&gt;C. albitibia&lt;/i&gt; being long and narrow. The larva of C. &lt;i&gt;albitibia&lt;/i&gt; is undescribed. For our study 3 unreared larvae, 1 pharate male, 1 adult male and 3 adult females of C. &lt;i&gt;albitibia&lt;/i&gt; from Ethiopia, collected and identified by Prof. A. Harrison were examined. The specimens were uncleared before mounting, and thus several features were not visible. The larvae are larger than those of &lt;i&gt;C. albitarsis&lt;/i&gt;, one having antennal length 210 &micro;m with AR = 2.10, which is outside the range of all Australian &lt;i&gt;Cricotopus&lt;/i&gt; (1.29&ndash;2.00), and appear to differ also from &lt;i&gt;C. albitarsis&lt;/i&gt; in the complex &lsquo;chunky&rsquo; development of a darkened mola resembling a broken tooth. The single Ethiopian pupa has a hyaline, blade-shaped thoracic horn, tapering towards the apex, spinules on TIII and IV densely covering the tergite and the hook row is very broad, 70% the width of TII, again outside the range of all Australian species (0.30&ndash;0.63). Adults appear very similar, including in the shape of the inferior volsella. However, the larva and especially the pupa appear incompatible with &lt;i&gt;C. albitarsis&lt;/i&gt;. Thus we consider C. &lt;i&gt;albitibia&lt;/i&gt; from Australia to have been misidentified by Freeman.&lt;/p&gt; &lt;p&gt; Examination of Hergstrom's proposed holotype and 2 paratypes of &lt;i&gt;&quot; C. albitarsis&lt;/i&gt; sp.nov &quot;, now in the A.N.I.C., showed that the legs have pigmented femora, the distal ends of the tibiae also are pigmented, and the tarsomeres of the forelegs are mid-brown (as on the specimens described here), although Hergstrom describes the legs as &quot;all legs pale yellow&quot;, and the key states &quot;Tibiae and tarsi completely without dark pigment&quot;, without mentioning the colour of the femora. She does not describe the pupa and larva. Other character states fit this species, and it appears to be Hergstrom's manuscript name C. &lt;i&gt;albitarsis&lt;/i&gt;, which is validated here with her authorship.&lt;/p&gt; &lt;p&gt; Molecular evidence for the identity of &lsquo;albitarsis&rsquo; comes from mature pupae from s.e. Queensland and Victoria close to identical to unreared larvae from across the eastern Australian range of the morphospecies. The situation regarding 2 specimens from Kambolgie Ck in southern Kakadu N.P. is uncertain. The female pupa (Mv- NT14.5.P2) conforms to the diagnoses here for &lt;i&gt;C. albitarsis&lt;/i&gt;. The sole larva (Mv-NT14.5.3), is near identical to the pupa on molecular evidence, and keys to &lt;i&gt;C. albitarsis&lt;/i&gt; but differs in the darker head capsule, the distinct Lauterborn organs and dark apex to the mandible less contrasting to a brown basal part. Unfortunately neither specimen is perfect &ndash; the pupa appears to have only 2 macrosetae on one side and on the other they are broken at the base and the larva has a worn/damaged median mentum. No additional candidates exist in older morphological material from the Alligator River Region. Molecular data indicate that these two specimens are divergent from &lt;i&gt;C. albitarsis&lt;/i&gt; and lie as sister to the clade &lsquo; albitarsis + wangi&rsquo; (Krosch &lt;i&gt;et al&lt;/i&gt;., submitted), much as implied by the morphology. Probably this constitutes a cryptic species but without further material with DNA associated, we will term the taxon &lsquo;divergent N.T. albitarsis&rsquo;.&lt;/p&gt; &lt;p&gt; &lt;i&gt;C. albitarsis&lt;/i&gt; is a widespread species across the continent, absent only from Tasmania. It tolerates elevated water temperatures and eutrophic to mine-contaminated standing and running waters, including the country&rsquo;s largest rivers and those salinated. This species occurs also in relatively unimpacted waters, as evidenced by some molecular collection sites.&lt;/p&gt;Published as part of &lt;i&gt;Drayson, Nick, Cranston, Peter S. &amp; Krosch, Matt N., 2015, Taxonomic review of the chironomid genus Cricotopus v. d.
