Morphological Species

Australia is predicted to have a high number of currently undescribed ostracod taxa. The genus Bennelongia De Deckker & McKenzie, 1981 (Crustacea, Ostracoda) occurs in Australia and New Zealand, and has recently shown potential for high speciosity, after the description of nine new species from Western Australia. Here, we focus on Bennelongia from eastern Australia, with the objectives of exploring likely habitats for undiscovered species, genetically characterising published morphological species and scanning classical species for cryptic diversity. Two traditional (morphological) species are confirmed to be valid using molecular evidence (B. harpago De Deckker & McKenzie, 1981 and B. pinpi De Deckker, 1981), while three new species are described using both morphological and molecular evidence. Two of the new species belong to the B. barangaroo lineage (B. dedeckkeri sp. nov. and B. mckenziei sp. nov.), while the third is a member of the B. nimala lineage (B. regina sp. nov.). Another species was found to be genetically distinct, but is not formally described here owing to a lack of distinguishing morphological features from the existing species B. cuensis Martens et al., 2012. Trends in diversity and radiation of the genus are discussed, as well as implications these results have for the conservation of temporary pool microfauna and our understanding of Bennelongia’s evolutionary origin.

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.

Three New Species

The caddis-flies of south-western Australia, the western section of Bassian province, have been examined; 48 species in nine families are recorded, descriptions of 24 new species are given and one species is synonymized; 79% of the species appear to be endemic. Only three families of the superfamily Limnephiloidea are recorded compared with 16 in the eastern section of the Bassian province. The Ecnomus continentalis species complex is briefly discussed, the lectotype male of Ecnomus continentalis is designated, figured and redefined; three new species, including one from eastern Australia, are described.

Shed Light

In this study, 13 previously recorded populations of Ilyodromus amplicolis De Deckker, 1981 from temporary aquatic habitats in Western Australia were scanned for undescribed species diversity using morphological and molecular systematics techniques. The study found congruent morphological and molecular evidence for three species that are new to science, all of which are formally described here (I. armacutis n. sp., I. sensaddito n. sp. and I. hiatus n. sp.). The findings shed light on the potential for further undescribed diversity in the genus Ilyodromus Sars, 1894.

The Pararchaeidae, a family of cryptic spiders known only from Australia and New Zealand, is revised. Six new genera: Anarchaea, gen. nov., Flavarchaea, gen. nov., Forstrarchaea, gen. nov., Nanarchaea, gen. nov., Ozarchaea, gen. nov., Westrarchaea, gen. nov., and 24 new species are described, 23 from mainland Australia and one from New Zealand. Anarchaea, gen. nov. from eastern Australia contains four species: A. corticola (Hickman, 1969), comb. nov. (type species), A. falcata, sp. nov., A. raveni, sp. nov. and A. robusta (Rix, 2005), comb. nov. Flavarchaea from eastern, southern and south-western Australia contains seven species: F. anzac, sp. nov., F. badja, sp. nov., F. barmah, sp. nov., F. hickmani (Rix, 2005), comb. nov., F. lofty, sp. nov., F. lulu (Rix, 2005), comb. nov. (type species) and F. stirlingensis, sp. nov. Forstrarchaea is represented only by the type species F. rubra (Forster, 1949), comb. nov. from New Zealand. Nanarchaea from eastern Australia contains two species: N. bryophila (Hickman, 1969), comb. nov. and N. binnaburra (Forster, 1955), comb. nov. (type species). Ozarchaea from Australia and New Zealand contains 16 species: O. bodalla, sp. nov., O. bondi, sp. nov., O. daviesae, sp. nov., O. forsteri, sp. nov., O. harveyi, sp. nov., O. janineae, sp. nov., O. ornata (Hickman, 1969), comb. nov. (type species), O. platnicki, sp. nov., O. saxicola (Hickman, 1969), comb. nov., O. spurgeon, sp. nov., O. stradbroke, sp. nov., O. valida, sp. nov., O. waldockae, sp. nov., O. werrikimbe, sp. nov., O. westraliensis, sp. nov. and O. wiangarie, sp. nov. Pararchaea Forster, 1955 is represented only by the type species P. alba Forster, 1955 from New Zealand. Westrarchaea, endemic to south-western Western Australia, contains three species: W. pusilla, sp. nov., W. sinuosa, sp. nov. (type species) and W. spinosa, sp. nov. A morphological cladistic analysis of the Pararchaeidae supported monophyly of the genera. Natural history information is summarised for each species where known, and the moulting behaviour, mating behaviour and egg sac of a pararchaeid species are described for the first time.

The ostracod genus Bennelongia De Deckker & McKenzie, 1981 occurs in Australia and New Zealand. We redescribe B. nimala from the Northern Territory and describe six new species from Western Australia belonging to the B. nimala (five species) and B. triangulata sp. nov. (one species) lineages: B. tirigie sp. nov., B. koendersae sp. nov., B. pinderi sp. nov., B. muggon sp. nov., B. shieli sp. nov. and B. triangulata sp. nov. For six of these seven species, we could construct molecular phylogenies and parsimonious networks based on COI sequences. We tested for specific status and for potential cryptic diversity of clades with Birky’s 4 theta rule. The analyses support the existence of these six species and the absence of cryptic species in these lineages. Bennelongia triangulata sp. nov. is a common species in the turbid claypans of the Murchison/ Gascoyne region. Bennelongia nimala itself is thus far known only from the Northern Territory. Bennelongia tirigie sp. nov., B. pinderi sp. nov. and B. muggon sp. nov. occur in the Murchison/ Gascoyne region, whereas B. koendersae sp. nov. and B. shieli sp. nov. are described from the Pilbara. With the six new species described here, the genus Bennelongia now comprises 31 nominal species.

Three new species of Tricholoma are described from Costa Rican montane forests with additional collections cited from the United States. The new species are Tricholoma felschii sp. nov., Tricholoma costaricense sp. nov. and Tricholoma atratum sp. nov. A discussion of Tricholoma luteomaculosum is also included. These taxa share morphological features of strong farinaceous odor and taste, pseudoparenchymatous pileal subcutis, and rugulose pileus at some stage of development. In addition, cheilocystidia occur in two of the taxa but not the third. Phylogenies are presented based on ITS sequences.

Three New Species

Three new species of Angraecum sect. Afrangraecum from Central Africa are here described and illustrated. They are morphologically similar to A. affine and A. cribbianum. Two of them, A. gereauanum and A. geerinckianum, are only known from Massif du Chaillu in Gabon and appear to be closely related based on morphological and preliminary molecular evidence. The third species, A. oliveirae, is endemic to São Tomé. A dichotomous key to all fourteen species of A. sect. Afrangraecum and a table with the distinguishing characters of the three new species and closely allied taxa are provided. A preliminary assessment of the conservation status of the new species is also presented, using the IUCN Red List categories and criteria.

Three New Species

The Australian Pangoniini include the most primitive known Tabanidae. Most are low-flying insects, which do not suck blood. They show progressive reduction in mandibles of the female, divisions of the third antenna1 segment, and hind tibia1 spurs. Their principal distribution is east coastal, from Torres Strait to southern New South Wales; there is a secondary centre of evolution in Western Australia; they are not known from Tasmania. Eighteen species are recognized, distributed among seven genera and subgenera, as follows: Austroplex, 3; Ectenopsis (Ectenopsis), 4; Ectenopsis (Parasilvius), 4; Ectenopsis (Leptonopsis), 2; Caenoprosopon, 4; Therevopangonia, 1. Three new species are described from Western Australia: Ectenopsis (?Ectenopsis) occidentalis, B ; Ectenopsis (Parasilvius) fusca, B, @ ; Ectenopsis (Leptonopsis) norrisi, B .

Some 2,000 Ptiliidae collected in the North and South Islands of New Zealand in 1983/1984 by Peter Hammond of the Natural History Museum, London, are determined to 34 species, four of which are new to the country. As there are very few previous records, most from the Auckland district of North Island, the Hammond collection provides much new distributional data. The three new species: Nellosana insperatus sp. n., Notoptenidium flavum sp. n., and Notoptenidium johnsoni sp. n., are described and figured; the genus Ptiliodes is moved from Acrotrichinae to Ptiliinae, and Ptenidium formicetorum Kraatz recorded as a new introduction. Information is provided to aid separation of the new species from those previously recorded.

High Degree

The genus Cryphocricos Signoret, 1850 was recently determined in a molecular phylogeny to be distantly related to other taxa of the subfamily Cryphocricinae to the extent that it is now once again the sole member of the subfamily. This exclusively New World group of aquatic bugs lives in fast and usually turbulent current and respires by means of a plastron. Efforts to identify morphological features to distinguish among the species have largely fallen short, and some species have been established based on features that exhibit a high degree of intraspecific variation overlapping those of other species. Presented here is a review of the 13 described species with discussions of their features and photos of type specimens, and three new species from Venezuela and Colombia are described. Also presented is a diagnostic attribute unique to the enigmatic Cryphocricos barozzii Signoret, 1850.
