Sea anemones (Cnidaria, Actiniaria) of Singapore: redescription and taxonomy of Phymanthus pinnulatus Martens in Klunzinger, 1877

Despite the ubiquity of sea anemones (Cnidaria: Actiniaria) in tropical ecosystems, our understanding of their biodiversity and taxonomy is limited. Here we re-establish the identity of an intertidal zooxanthellate species, Phymanthus pinnulatus Martens in Klunzinger, 1877. Originally described from a single preserved specimen in the Berlin Museum by CB Klunzinger, his brief...

Cryptic diversity in Lithobates warszewitschii (Amphibia, Anura, Ranidae)

Lithobates warszewitschii is a species of ranid frog distributed from southern Honduras to Panama. This species suffered severe population declines at higher elevations (above 500 m a.s.l.) from the 1980s to early 1990s, but there is more recent evidence of recovery in parts of its range. Here we advocate for the status of Lithobates warszewitschii as a candidate cryptic species...

Four new species of Hexanchorus Sharp from Ecuador (Coleoptera, Elmidae) with DNA barcoding and notes on the distribution of the genus

The riffle beetle genus Hexanchorus Sharp, 1882 is distributed from Mexico to Argentina, forming an important component of the freshwater invertebrate fauna of Latin America. With 21 described species, Hexanchorus represents one of the most speciose Larainae genera, but its real diversity is likely much higher. We analysed material from a relatively small area in Ecuador...

A taxonomic note on the helicoid land snail genus Traumatophora (Eupulmonata, Camaenidae)

Traumatophora triscalpta (Martens, 1875) is reported for the first time from the Tianmushan Mountains, Zhejiang Province, and its morpho-anatomy is described based on this new material. The genus Traumatophora is redefined on the basis of both shell and genital anatomy of its type species. The presence of the dart apparatus suggests this genus belongs to the subfamily...

Three new species of Chromis (Perciformes, Pomacentridae) from the Philippines, collected between 75–150 m depth, are described by a combination of morphological features and their coloration. Chromis gunting sp. n. was found in Batangas and Oriental Mindoro, and differs from its congeners in body depth (2.1–2.2 in SL), and color of adults, light brown, with a silver area on the...

Mitochondrial genomes of the stoneflies Mesonemoura metafiligera and Mesonemoura tritaenia (Plecoptera, Nemouridae), with a phylogenetic analysis of Nemouroidea

In this study, two new mitochondrial genomes (mitogenomes) of Mesonemoura metafiligera and Mesonemoura tritaenia from the family Nemouridae (Insecta: Plecoptera) were sequenced. The Mesonemoura metafiligera mitogenome was a 15,739 bp circular DNA molecule, which was smaller than that of M. tritaenia (15,778 bp) due to differences in the size of the A+T-rich region. Results show...

Prognathodes geminus, a new species of butterflyfish (Teleostei, Chaetodontidae) from Palau

A new species of the butterflyfish genus Prognathodes (Chaetodontidae) is described from two specimens collected at a depth of 116 m off Ngemelis Island, Palau. Prognathodes geminus sp. n. is similar to P. basabei Pyle & Kosaki, 2016 from the Hawaiian archipelago, and P. guezei (Maugé & Bauchot, 1976) from the western Indian Ocean, but differs from these species in the number of...

Lophorrhinides muellerae (Coleoptera, Scarabaeidae, Cetoniinae): a new genus and species from southern Tanzania

A male cetoniine specimen recently submitted for identification from the Ditsong Museum of Natural History (Pretoria, South Africa) has been found to represent a yet unknown species. A review of the recently published book of Beinhundner (2017) has further revealed that one of the specimens mistakenly figured as Lophorrhina donckieri Bourgoin, 1913 in that work is most likely the...
