This is the first record of Late Jurassic (Volgian) otoliths from the boreal province of Russia. Two new species– Palealbula korchinskyi n. sp. and Palealbula moscoviensis n. sp. – are described representing otoliths of putative stem- albuliform affinities of unresolved familiar position. The phylogeny of Palealbula and the supposedly related genus Protalbula is discussed in the light of the new findings presented in this article. Both genera are shown to represent a common faunal element in the early evolutionary phase of teleosts during the Late Jurassic and Early Cretaceous.

Two New Species

A new genus and two new species of fossil Elateridae are described and illustrated: Paralithomerus gen. nov., P. exquisitus sp. nov, and P. parallelus sp. nov. Both species were collected from the Late Jurassic-Early Cretaceous Yixian Formation of western Liaoning, China. Fossil elaterids expressing a sutured mesoventrite have been otherwise discovered only from the Upper Jurassic strata of Karatau.

A new genus and two new species of the extinct family Hexagenitidae, Epicharmeropsis hexavenulosus gen. et sp. nov. and Epicharmeropsis quadrivenulosus sp. nov., are described from the Late Jurassic-Early Cretaceous Yixian Formation, Hebei and Liaoning Provinces in China. Detailed description and illustration of the specimens along with a brief review of Hexagenitidae are given. By comparing with the imago specimens of so-called Ephemeropsis which were previously reported from China, we believe these Ephemeropsis-like specimens should be placed into Epicharmeropsis gen. nov. and Ephemeropsis Eichwald could be absent in China.

Two New Species

Two new species of blind ground beetles are described from the southern United States. One species, Anillinus relictussp. nov. (type locality: E of Oneonta, Blount County, Alabama), based on the structure of male genitalia, is similar to Texan Anillinus, in particular to the endogean A. sinuatus Jeannel. The second species, A. felicianussp. nov. (type locality: 4 mi SW Jackson, West Feliciana Parish, Louisiana), is superficially similar to the endogean A. sinuaticollis Jeannel from Roane County, Tennessee, and represents the first record of the genus for the state of Louisiana. All species are illustrated with digital images of habitus, body parts, and male and female genitalia. Biogeographical and evolutionary implications of the new findings are discussed.

Low Diversity

A new anostracan genus with two new species in the family Branchipodidae is described from the Murray Darling basin, Australia. This is the first record of the family from Australia. Males of Australobranchipus typically have long and elaborate frontal appendages comparable to those in the branchipodid genera Branchipus and Pumilibranchipus. Females have a compact brood pouch like other branchipodid genera. Two new species in this genus are described (A. parooensis and A. gilgaiphila). Along with recent additions in Branchinella and Parartemia, and confirmation of the presence of Streptocephalus, these new findings change the concept of low diversity among higher anostracan taxa in Australia. Australobranchipus is also remarkable for having the shortest known life cycle of any Australian anostracans. In the type locality, which typically holds water for only two to six weeks in occasional years, and when cultured, it matures within a week and dies within two weeks, allowing these species to avoid competition with other anostracans.

The Late Jurassic–Early Cretaceous Slottsmøya Member of the Agardhfjellet Formation in central Spitsbergen has yielded two new species of asteroids and two species of ophiuroids, one of which is described as new. Polarasterias janusensis Rousseau & Gale gen. et sp. nov. is a forcipulatid neoasteroid with elongated arms, small disc and very broad ambulacral grooves with narrow adambulacrals. Savignaster septemtrionalis Rousseau & Gale sp. nov. is a pterasterid with well-developed interradial chevrons. The Spitsbergen specimens are the first described articulated material of Savignaster and reveal the overall arrangement of the ambulacral groove ossicles. Ophiogaleus sp. is an ophiacanthid with relatively long jaws and lateral arm plates, with a coarsely reticulate outer surface. Here again, we report the first articulated skeletons of this genus, providing unprecedented insights into the disc morphology. Ophioculina hoybergia Rousseau & Thuy gen. et sp. nov. is an ophiopyrgid with a well-developed arm comb and tentacle pores reduced to within-plate perforations starting at median arm segments. These new finds are important additions to the asterozoan fossil record with regard to their good degree of articulation and the high latitudinal position of the localities. They significantly add to the set of exhaustively known fossil asterozoan taxa which play a key role in the phylogenetic analysis and reconstruction of evolutionary history.

Gut Symbionts

This paper discusses new findings relating to the first known diversity of trichomycete gut symbionts from Colombia. All species were associated with aquatic insects in the orders Diptera and Ephemeroptera collected from various localities in the tropical Eastern Ridge of Santander. Among the reported taxa, we describe two new species, Gauthieromyces colombiensis (Harpellales), phenotypically similar to the European G. microsporus, and Paramoebidium santanderensis (Amoebidiales) characterized by retaining the cystospore attached to the growing thallus after germination. Both taxa were found in the hindgut of mayfly nymphs. We also provide 17 new geographic records of trichomycetes for Colombia. Taxonomic and biogeographic implications of these records are discussed.

In May–June 2017 an expedition on board RV ‘Investigator’ sampled benthic communities along the lower slope and abyss of eastern Australia from off Tasmania to the Coral Sea. Over 200 sabellariid specimens of the genera Phalacrostemma and Gesaia were collected during the voyage and deposited in the Australian Museum. Here we describe two new species Gesaia csiro n. sp. (4414–4436 m) and Phalacrostemma timoharai n. sp. (1013–1093 m). We did not formally describe another species of Phalacrostemma due to poor condition of the single specimen. Gesaia csiro n. sp. is the first record of the genus from Australian waters (only a planktonic larva attributed to the genus has previously been recorded), and it can be distinguished from other congeners by the smooth surface of inner paleae, distal thecae of outer paleae with long, irregular and expanded distal fringe and circled distal margin. Phalacrostemma timoharai n. sp. differs from congeners by the following combination of characters: presence of the buccal flap, absence of tentacular filament, 18–22 pairs of outer paleae, two pairs of neuropodial cirri on first thoracic segment, and only one pair of lateral lobes on second thoracic segment. Morphological descriptions are accompanied by mitochondrial cytochrome c oxidase subunit 1 (COI) and ribosomal (16S, 18S and 28S) sequence data. A key to all Australian species of sabellariids is given.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

The genus chiton Loricella is revised. It comprises nine species. Two of these species, L. neoguinensis n. sp. and L. solomonensis n. sp., are described as new. Based on the analysis of morphological features studied using a scanning electron microscope, a revised diagnosis of the genus is provided. The characters diagnostic for this that distinguish it from the related genus Squamophora are as follows: a tubular hollow inside the dorsal scales, bristles on the dorsal side of the girdle, a wide ventral mouth region, a narrow mantle fold covered with simple longitudinally ribbed scales, smooth ventral scales, pits arranged in longitudinal rows in the central area of the tegmentum, and a bicuspid head of the major lateral teeth of the radula.
