Revision of the genus Hannia (Teleostei, Terapontidae), with description of a new species, Hannia wintoni, from the Kimberley, Western Australia

The systematics of the genus Hannia Vari 1978, endemic to freshwater habitats of remote north-western Australia, is revised in light of recent collections in the region and a molecular study of the group that identified an undescribed candidate species. A new freshwater fish species (Hannia wintoni sp. nov) is described based on analysis of multiple nuclear genetic markers (53 allozyme loci), mitochondrial DNA sequence data (601 bp cytochrome b) and morphology (examination of a suite of 66 morphometric and meristic characters). Head profile, postorbital length, maximum length, preopercular spines and pectoral-fin rays are characters that best distinguish H. wintoni sp. nov from its only congener, H. greewayi. While the existing description of H. greenwayi is robust and accurate, we present a number of additional characters that enhance to the original description, based on type and fresh material. Information on the known distribution, habitats and conservation status of the two species is summarised. The new species is a narrow-range endemic.

The ‘maccullochi species group’ of rainbowfishes are small and distinctly patterned freshwater fishes of streams and swamps, comprising around eight species. The species from which the group bears its name, Melanotaenia maccullochi Ogilby, 1915, has been thought to comprise three forms occurring in distinct geographic areas, and recent mitochondrial genetic data provides matching patterns of likely inter-specific divergence. Here we undertake a detailed investigation of the taxonomic status of M. maccullochi using a combined lines of evidence approach incorporating multiple nuclear genetic markers (55 allozyme loci), mitochondrial DNA sequence data (1141 bp cytochrome b) and morphology (examination of a suite of 38 morphometric and meristic characters). As all three datasets provide support for a three-way split, we accordingly describe two new species and redescribe M. maccullochi sensu stricto. McCulloch’s Rainbowfish M. maccullochi, a species with brown body stripes and red fins occurs in northeast Queensland and is redescribed based on 338 specimens, 13.1–53.0 mm SL. This species was one of the first rainbowfishes to become known in the aquarium hobby. A second form with darker stripes on a contrasting light white-grey body and with distinct sub-marginal black bands in the dorsal and anal fins, distributed across northern and eastern Cape York Peninsula, Torres Strait and southern central New Guinea, is described as Sahul Rainbowfish M. sahulensis sp. nov. based on 267 specimens, 13.4–48.4 mm SL. A diminutive and well geographically isolated form occurring below the escarpment of the Tabletop Range in Litchfield National Park, Northern Territory possessing a more prominent and purplish mid-lateral stripe, is described as the Little Rainbowfish Melanotaenia wilsoni sp. nov. based on 50 specimens, 19.3–33.3 mm SL. A combination of morphological characters is useful for separating the respective taxa with M. wilsoni sp. nov. the most distinctive, typically having fewer vertebrae, lateral scales, cheek scales, procurrent caudal rays and anal rays and proportionally a shorter maxilla and snout than either of the other two species. Useful characters for further separating M. sahulensis sp. nov. from M. maccullochi include slightly higher counts of vertebrae, lateral scales and anal rays and proportionally greater body depth, body width and pre-dorsal distance. Information on the known distribution, habitats and conservation status of the three species is summarised, with the Northern Territory species being a narrow-range endemic with specific environmental requirements.

Allozyme Loci

The freshwater melanotaeniid genus Cairnsichthys is endemic to a relatively small area of specialised habitat within the Wet Tropics bioregion of north-eastern Queensland, Australia. It was previously considered as monotypic, including only a single species, C. rhombosomoides (Nichols & Raven, 1928). The recent discovery of an apparently-isolated population in the Daintree rainforest, approximately 120 km north of the known range extent, prompted a detailed investigation of its taxonomic status using a combined lines of evidence approach. We provide compelling evidence from multiple nuclear genetic markers (52 allozyme loci), mitochondrial DNA sequence data (1141 bp cytochrome b) and morphology (examination of a suite of 38 morphometric and meristic characters) that supports north-south splitting of C. rhombosomoides. Accordingly, we describe the northern population as a distinct species, C. bitaeniatus sp. nov., on the basis of 25 specimens, 34.7–65.6 mm SL. The new species differs morphologically primarily by having a more slender and narrow shape, featuring a flatter, straighter predorsal profile and shorter second dorsal fin base; possession of slightly smaller scales, reflected in higher counts of lateral scales and predorsal scales; typically more vertebrae; and colour differences including a more robust, short black stripe across the upper operculum, a pronounced yellow patch on the anteroventral body and usually a more conspicuous second dark stripe on the lower body, with adult males generally having yellowish compared to reddish fins. We also provide a generic diagnosis for Cairnsichthys and a redescription of C. rhombosomoides. Information on the known distribution, habitats and conservation status of species in the genus is summarised, the new species being of particular concern as a narrow range endemic with specific environmental requirements.

ABSTRACT Tudivasum Rosenberg & Petit, 1987 is a morphologically distinct gastropod genus of low diversity. All but one species are known from Australia and they occur from the intertidal zone down to hundreds of metres on the continental shelf. These carnivorous gastropods are thought to have intracapsular development. The six currently recognized extant species are reviewed here and their geographical ranges clarified. Two new species, Tudivasum chaneyi n. sp. and T. ashmorense n. sp., are described from Ashmore Reef, Western Australia, and are characterized by differences in protoconch colour and shell sculpture. The third new species, T. westrale n. sp., is described from the mid-west coast of Western Australia, where it has long been misidentified as T. spinosum (H. Adams & A. Adams, 1864). We generated a molecular phylogeny based on mitochondrial DNA sequence data to test morphological species concepts and reconstruct relationships among four of the described species. High levels of divergence within one of the new species could indicate an additional cryptic species.

A new species of the eyeless eleotrid genus Milyeringa is described from wells sunk on Barrow Island, Western Australia. Milyeringa justitia n. sp. is the third species of the genus to be named. Morphological data and cytochrome c oxidase subunit I (COI) DNA sequence data from a wide sample of localities at which the genus occurs was used to evaluate relationships and species limits. Milyeringa veritas is redescribed, and M. brooksi is synonymised with M. veritas. The unique form and ecology of these fishes, plus the threats to their survival, warrants immediate and continuing attention in management.

A New Species

A new orchid species, Liparis funingensis, from Yunnan, China, is described and illustrated in this study based on morphological and molecular analyses. A detailed comparison between the newly discovered orchid and other members of Liparis was performed. This new plant is characterized by an obovate lip and is trilobed. The sidelobes are semiorbicular and fleshy, and the midlobe is short and bilobed with triangular lobes. The disc has a deeply bilobed basal callus and two longitudinal lamellae from the base extending to above the middle. There are four pollinia in two pairs, with each pair exhibiting long caudicles without a viscidium. The rostellum also has a bursa synovialis. These features distinguish this new orchid from all other known species of Liparis. A phylogenetic analysis was subsequently performed to determine the systematic position of this enigmatic species. A molecular study based on nuclear ribosomal ITS and plastid matK DNA sequence data indicates that L. funingensis is a member of L. layardii subclade.

Basic morphology, scanning electron microscopy, and DNA sequence data from the plastid trnL–F region and the nuclear internal transcribed spacer (ITS) regions were used to delimit the species of a recently circumscribed clade of Cuscuta (Convolvulaceae) and to investigate their phylogenetic relationships. This clade comprises the Cuscuta gracillima complex from Mexico, Central and northern South America, a group which is characterized by inflorescences that appear to emerge directly from the host stem. Eight lineages are recognized, with two of them described here as new species: Cuscuta punana Costea & Stefanović, sp. nov. from Ecuador and Cuscuta vandevenderi Costea & Stefanović, sp. nov. from Mexico. Cuscuta colombiana Yunck is redefined to include Cuscuta aristeguietae Yunck., and Cuscuta deltoidea Yunck. is broadened to encompass Cuscuta serruloba Yunck. A taxonomic treatment with an identification key, descriptions, and illustrations is provided; the biogeography and conservation status of the eight species are also discussed.
