Genetic Species

The ostracod genus Bennelongia De Deckker & McKenzie, 1981 is endemic to Australia and New Zealand. Extensive sampling in Western Australia (WA) revealed a high specific and largely undescribed diversity. Here, we describe seven new species belonging to the B. barangaroo lineage: B. timmsi sp. nov., B. gnamma sp. nov., B. hirsuta sp. nov., B. ivanae sp. nov., B. mcraeae sp. nov., B. scanloni sp. nov. and B. calei sp. nov., and confirm the presence of an additional species, B. dedeckkeri, in WA. For five of these eight species, we could construct molecular phylogenies and parsimonious networks based on COI sequences. We also tested for cryptic diversity and specific status of clusters with a statistical method based on the evolutionary genetic species concept, namely Birky’s 4 theta rule. The analyses support the existence of these five species and a further three cryptic species in the WA B. barangaroo lineage. The molecular evidence was particularly relevant because most species described herein have very similar morphologies and can be distinguished from each other only by the shape, size and position of the antero-ventral lapel on the right valve, and, in sexual populations, by the small differences in shape of the hemipenes and the prehensile palps in males. Four species of the WA B. barangaroo lineage occur in small temporary rock pools (gnammas) on rocky outcrops. The other four species are mainly found in soft bottomed seasonal water bodies. One of the latter species, B. scanloni sp. nov., occurs in both claypans and deeper rock pools (pit gnammas). All species, except for B. dedeckkeri, originally described from Queensland, have quite clearly delimited distributions in WA. With the seven new species described here, the genus Bennelongia now comprises 25 nominal species but several more await formal description.

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.

Abstract A new species of miniature fish of the characid genus Priocharax is described from a small lake near the rio Ipixuna, rio Purus drainage, Amazonas State, Brazil. It is distinguished from all congeners except P. pygmaeus by the lower number of teeth on the maxilla and dentary. It differs from P. pygmaeus by the presence of two postcleithra and 22–27 branched anal-fin rays (vs absence and 19–22). The new species is further distinguished from other species of Priocharax by a combination of characters involving the number of pelvic-fin rays and branched anal-fin rays, the number of postcleithra, the shape of postcleithrum 3, and the absence of the claustrum. Molecular evidence based on COI sequences of all valid species of Priocharax also corroborates the validity of this new species.

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.

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.

Taxonomic Approach

Water mites of the Hygrobates fluviatilis-complex are often the most ubiquitous and usually the most abundant water mite group in the running waters of the Palaearctic and Balkans. In the present study we used an integrative taxonomic approach by applying partial COI sequences (DNA-barcodes) to describe two new species of the fluviatilis-complex from the Balkan Peninsula, H. balcanicus Pešić sp. nov. (Bulgaria, North Macedonia, Greece) and H. mediterraneus Pešić sp. nov. (Montenegro). Phylogenetic analysis based on COI data placed H. balcanicus sp. nov. as the sister species of the clade grouping H. turcicus Pešić, Esen & Dabert, 2017 and H. ulii Pešić et al. 2019 whereas H. mediterraneus sp. nov. is placed as the sister species of H. grabowskii Pešić et al. 2019, with about 20% and 13% K2P divergence, respectively, between the closest relatives.

Five new species of chewing lice of the genus Myrsidea Waterston from the passerine family Pycnonotidae are described and illustrated. They and their type hosts are: M. masoni ex Bleda eximius (Hartlaub), M. chesseri ex Criniger barbatus (Temminck), M. palmeri ex Andropadus curvirostris Cassin, M. wombeyi ex Bleda syndactylus (Swainson), and M. marksi ex Phyllastrephus albigularis (Sharpe). These represent the first species of pycnonotid Myrsidea to be described from African hosts. Partial mitochondrial cytochrome oxidase I (COI) sequences were collected for these species and additional species of Myrsidea, which support the genetic distinctiveness of these new species.

We provide a guide for identification of Comatulidae, a family of crinoid echinoderms, incorporating morphological and molecular evidence. A non-dichotomous key for all genera is included, as well as photographs of species most likely to be encountered in the tropical western Pacific Ocean. Based on sequencing of cytochrome oxidase subunit I (COI), and other genes when necessary, we identified four cases where taxonomic revision was needed. We synonymized Comaster nobilis under Comaster schlegelii, and Clarkcomanthus exilis under Clarkcomanthus comanthipinnus, and re-described Clarkcomanthus albinotus. We also showed the variation of COI sequences within and among species, which varies from lineage to lineage. In some cases, specimens with obvious morphological disparity possessed very little intraspecific molecular diversity (<1%). In others, specimens with nearly identical external appearances exhibited quite divergent COI sequences (up to 6%). These results, combined with the non-dichotomous key herein, offer guidelines for identification and discussion of existing and new species of Comatulidae.

A New Species

Caenestheriella mariae, a new species of the Spinicaudata (Branchiopoda), is described from Western Australia. It is most similar to the Australian Caenestheriella packardi (Brady, 1886), from which it differs most notably by several characters in the head region. In contrast to Caenestheriella packardi, Caenestheriella mariae sp. nov. (1) has a small hump anterior to the occipital condyle, (2) has a 90° pointed angle between the eye lobe and the rostrum, (3) has a more prominent eye lobe, and (4) lacks distinct sculpturing between the growth lines of the carapace. Caenestheriella mariae lives in gnamma (rock) pools when they hold water in winter-spring.
