A New Species

The Australian pyralid stem borers of Gramineae, Cyperaceae, and Juncaceae, previously assigned to Schoenobius Duponchel and Scirpophaga Treitschke, are here referred to six genera. Scirpophaga Treit. - Eight species are recognized: S. chrysorrhoa Zeller, S. phaedima, sp. nov., S. limnochares, sp. nov., S. xantharrenes, sp. nov., S. imparella (Meyrick), S. helodes, sp. nov., S. percna, sp. nov., and S. ochroleuca (Meyrick). Though some of these bear a superficial resemblance to the true rice stem borers, the genus includes species whose larvae attack sedges (Cyperaceae). Helonastes, gen. nov. - The genus is based on a new species, H. acentrus, associated with Eleocharis (Cyperaceae) in central Queensland. Niphadoses, gen. nov.-The genus is erected to include three new Australian species, N. palleucus, which is associated with cultivated rice in north-western Australia, N. elachia, and N. hoplites, together with N. chionotus (Meyrick) from New Guinea and N. gilbiverbis (Zeller) from India. Catagela Walker. - A new species, C. adoceta, from northern Australia, is described. Tryporyza gen. nov. - The genus is established to receive the two important stem-borer pests of cultivated rice, Tipanaea innotata Walker from south-east Asia and northern Australia and Chilo incertulas Walker from south-east Asia, previously referred to Scirpophaga and Schoenobius respectively. Also included are Scirpophaga butyrota Meyrick from New Guinea and Schoenobius melanostigmus Turner from the Cape York Peninsula. It is suggested that T. innotata already occurred in northern Australia before European settlement. Tipanaea Walker. - The genus is restricted to the single Australian species, T. patulella Walker, associated with Juncaceae. Genitalic and other structures used to distinguish these genera are discussed. The genitalia of both sexes and the wings of the Australian species are figured, and keys to the genera and species are included.

Australian Species

Acacia sensu stricto is found predominantly in Australia; however, there are 18 phyllodinous taxa that occur naturally outside Australia, north from New Guinea to Indonesia, Taiwan, the Philippines, south-western Pacific (New Caledonia to Samoa), northern Pacific (Hawaii) and Indian Ocean (Mascarene Islands). Our aim was to determine the phylogenetic position of these species within Acacia, to infer their biogeographic history. To an existing molecular dataset of 109 taxa of Acacia, we added 51 new accessions sequenced for the ITS and ETS regions of nuclear rDNA, including samples from 15 extra-Australian taxa. Data were analysed using both maximum parsimony and Bayesian methods. The phylogenetic positions of the extra-Australian taxa sampled revealed four geographic connections. Connection A, i.e. northern Australia?South-east Asia?south-western Pacific, is shown by an early diverging clade in section Plurinerves, which relates A. confusa from Taiwan and the Philippines (possibly Fiji) to A. simplex from Fiji and Samoa. That clade is related to A. simsii from southern New Guinea and northern Australia and other northern Australian species. Two related clades in section Juliflorae show a repeated connection (B), i.e. northern Australia?southern New Guinea?south-western Pacific. One of these is the ?A. auriculiformis clade', which includes A. spirorbis subsp. spirorbis from New Caledonia and the Loyalty Islands as sister to the Queensland species A. auriculiformis; related taxa include A. mangium, A. leptocarpa and A. spirorbis subsp. solandri. The ?A. aulacocarpa clade' includes A. aulacocarpa, A. peregrinalis endemic to New Guinea, A. crassicarpa from New Guinea and Australia, and other Australian species. Acacia spirorbis (syn. A. solandri subsp. kajewskii) from Vanuatu (Melanesia) is related to these two clades but its exact position is equivocal. The third biogeographic connection (C) is Australia?Timor?Flores, represented independently by the widespread taxon A. oraria (section Plurinerves) found on Flores and Timor and in north-eastern Queensland, and the Wetar island endemic A. wetarensis (Juliflorae). The fourth biogeographic connection (D), i.e. Hawaii?Mascarene?eastern Australia, reveals an extreme disjunct distribution, consisting of the Hawaiian koa (A. koa, A. koaia and A. kaoaiensis), sister to the Mascarene (R�union Island) species A. heterophylla; this clade is sister to the eastern Australian A. melanoxylon and A. implexa (all section Plurinerves), and sequence divergence between taxa is very low. Historical range expansion of acacias is inferred to have occurred several times from an Australian?southern New Guinean source. Dispersal would have been possible as the Australian land mass approached South-east Asia, and during times when sea levels were low, from the Late Miocene or Early Pliocene. The close genetic relationship of species separated by vast distances, from the Indian Ocean to the Pacific, is best explained by dispersal by Austronesians, early Homo sapiens migrants from Asia.

A New Species

A new species of megophryid frog of the genus Leptolalax is described from the Tamdil wetlands of Mizoram State, north-eastern India. L. tamdil new species, is compared with congeners from India and other parts of south-east Asia. The new species is diagnosable in showing the following combination of characters: SVL 32.3 mm in the only male and 31.8 mm in the only female known; dorsum tuberculate; eyelids with tubercles; tympanum and supratympanic fold distinct; supratympanic fold extending to posterior edge of tympanum; macroglands, including preaxillary, pectoral, femoral and ventrolateral glands present; Finger II > I; toe tips not dilated, bearing dermal fringes; relatively long hind limbs, with heels in contact when limbs are held perpendicular to body; dorsum with dark blotches; flanks with small dark blotches; dark tympanic mask present; venter pale; labial bars present and limbs with dark cross-bars.

In Australia the genus Euphorbia L., sensu stricto, is represented by seven indigenous species in three subgenera. One species has been reported from Papua New Guinea and parts of South-east Asia, another from the New Hebrides; the remaining species are endemic to Australia. Two taxa are described as new species, viz. Euphorbia parvicaruncula and Euphorbia planiticola, and two former species are reduced to infraspecific rank, viz. Euphorbia tannensis subsp. eremophila, and Euphorbia tannensis subsp. eremophila var. finlaysonii. Observations are made on geographical distributions, interspecific relationships, and chromosome numbers.

The genus Euhemicera Ando, 1996 (Tenebrionidae: Cnodalonini) is recorded from Myanmar for the first time. The newly identified representatives of this genus are described herein as Euhemicera amicorum sp. n.. An updated species catalogue of Euhemicera with distributional data is provided. Currently, one hundred species are known to represent this genus. Available data reveals that Euhemicera is widely distributed throughout the oriental region, with the highest diversity in South East Asia.

A New Species

A new species of Leptostraca, Nebalia cambodiana sp. nov. (Crustacea: Malacostraca), is described from Cambodia. The specimen was collected by light traps on a diving deck where the bottom consisted of fine sand and gravel. The new species is distinguished from all other known species of Nebalia by the following characteristics: rostrum very long, length nearly 3.5 times width; a compound eye with one distinct dorsal papilla and four small lobes on distal margin; an antennular flagellum with nine articles; the fourth article of the antennular peduncle with only one distal thick seta; the antennular scale is elliptical, with a length that is 2 times the width; exopod of the second maxilla is the same length as first article of its endopod; pleonites 5 to 7 with rounded denticles along their posterior dorsal margins; the protopod of pleopod 4 lacks serration along the posterior margin; and anal plates with distinct lateral ‘shoulder’.The new species is the first species of Leptostraca found in South-east Asia. In this paper, we provide illustrations and a detailed description of the diagnostic characteristics of N. cambodiana sp. nov.

A new species of Ixodes is described from two male specimens that have a distinctive ventrolateral horn-like projection on palpal article 1. This structure is not found in any other Australian species, but is similar to that of I. zaglossi Kohls, 1960 from the long-beaked echidna of Papua New Guinea. I present a revised key to accommodate the five males of Australian Ixodes described or re-described since 1970. I also briefly review the 26 Australian species of Ixodes.
