Two new species of Bowenia Hook. ex Hook, f. (B. papillosa Hill and B. eocenica Hill) represent the first report of this genus in the fossil record. Cuticular and architectural differences support their new specific status; however, the overall morphological similarity of the two fossil species to extant Bowenia suggests that evolution in this genus is slow. The fossil localities illustrate that in the Eocene Bowenia occurred further south than it does at present. Physiognomic analyses of the fossil dicotyle-donous leaves at the two localities indicate a warm-temperate to subtropical climate. It is therefore likely that the fossil species lived in environments similar to that of extant B. spectabilis Hook. ex Hook, f.

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.

Two new species of Terebrasabella Fitzhugh & Rouse, 1999 are described from eastern Australia. Terebrasabella hutchingsae sp. nov., was found from preserved coral rock debris collected in 1977 on the outer Barrier Reef near Lizard Island, Queensland. Terebrasabella fitzhughi sp. nov., was found alive in burrows in and among spirorbin serpulid tubes on intertidal rocks in Tasmania in 1996. Both species were found in mucoid tubes, and brood their young in a manner similar to the only other described species of Terebrasabella, T. heterouncinata Fitzhugh & Rouse, 1999. Terebrasabella hutchingsae sp. nov., is exceptional as it possesses a type of thoracic neurochaetal uncinus different from the other two species, and which is similar to the notochaetal acicular “palmate hook” seen in Caobangia. Descriptions of both species are given, and the diagnosis for Terebrasabella is emended. Larval and chaetal morphology and relationships among of the three known Terebrasabella spp. are discussed.

Limodromus emetikos sp. n. (Coleoptera: Carabidae) is described and illustrated from Baltic amber (Eocene). Based on its morphological features, the new species is considered a sister taxon of the extant Holarctic assimilis species group. Furthermore, the specimen described here could represent a case of stress-triggered regurgitation, which would represent the first fossil record of such a process in beetles.

A New Species

Pelomedusoides is the most diverse clade of side-necked turtles and there is an extensive fossil record (de Broin, 1988; Lapparent de Broin, 2000; Gaffney et al., 2006, 2011) that dates back at least to the Barremian (Lower Cretaceous) (Romano et al., 2014). Its large fossil record evidences a greater diversity in the past, particularly at the end of the Mesozoic, and exhibits a good sampling of species that are represented by skull material (Gaffney et al., 2006, 2011). As a consequence, the most complete and recent phylogenetic hypotheses for this clade (e.g. Romano et al., 2014; Cadena, 2015) are based on matrices comprising a great amount of cranial characters derived largely from Gaffney et al. (2006, 2011). In addition, it is well established that shell characters show a lot of phenotypic plasticity, even in the fossil species (Romano, 2008; Gaffney et al., 2006, 2011). In most cases it consequently is not justified to rely on “diagnostic features” of poorly informative shell-only material for describing a new species. Because of that, most authors remark new morphotypes in the literature when such aberrant specimens are recovered, but do not make any nomenclatural act by proposing a new yet poorly supported species (e.g. Romano et al., 2013; Ferreira & Langer, 2013; Menegazzo et al., 2015). Unfortunately, such a supposedly new bothremydid turtle (Pleurodira: Bothremydidae) from the Early Paleocene of Brazil was recently described based on poorly diagnostic remains (Carvalho et al., 2016; hereafter CGB, for the authors initials) and a correction of this unfounded nomenclatural act is required. In addition I present some comments on shell only material from Brazil in order to guide splitter-taxonomists to stop describing poorly preserved fossil specimens as new species.

Two new species, Itaphlebia exquisita sp. nov and Itaphlebia laeta sp. nov., were collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou, Inner Mongolia, China. A key to the species of the genus Itaphlebia is provided and diagnosis of the genus is revised. Itaphlebia exquisita sp. nov differs from other species in having an extra medial vein branch. Itaphlebia laeta sp. nov shows a transitional character to the extant genera by having a simple Sc. These new findings expand the distribution of Itaphlebia from middle-southern Russia to northeastern China.

The family Discidae has undergone extensive speciation in the Macaronesian region (eastern Atlantic Ocean), with 11 endemic species recognised from Madeira and the Canary Islands in recent checklists (Bank, Groh & Ripken 2002; Seddon 2008; Fauna Europaea database project 2011), grouped into the genera Keraea Gude, 1911 and Discus Fitzinger, 1833: K. deflorata (R.T. Lowe, 1855) and D. (Atlantica) guerinianus (R.T. Lowe, 1852), from Madeira; and nine species from the Canary Islands: K. garachicoensis (Wollaston, 1878), D. scutula, (Shuttleworth, 1852), D. engonatus (Shuttleworth, 1852), D. textilis (Shuttleworth, 1852), D. retextus, (Shuttleworth, 1852), D. putrescens (R.T. Lowe, 1861), D. ganodus (J. Mabille, 1882), D. gomerensis Rähle, 1994, and D. kompsus (J. Mabille, 1883). In contrast with the anatomical data known for the European and North American genera Discus and Anguispira Morse, 1864 (Uminski 1962; Pilsbry 1948), there has hitherto been no information published on the internal anatomy of the Canary Islands and Madeiran species, which are known only by their shell characters. In this paper we raise Atlantica to the rank of genus in the Discidae and describe shell and anatomical characters for two new species from La Gomera and Tenerife, respectively. They are grouped in a new subgenus of Atlantica, largely restricted to the laurisilva. This laurel-rich forest occurs in humid subtropical and warm-temperate regions with little variability in temperatures and is developed between 600 and 1,200 m above sea level in the Canary Islands (Yanes et al. 2009b: Fig. 2).

First records of peracarid crustaceans obtained from the Cayo Matías Ocean Blue Hole, southwestern Cuba, aredocumented. In addition, two new species of isopod and amphipod are herein described. Gnathia micheli n. sp. (Isopoda,Gnathiidae) and Boca normae n. sp. (Amphipoda, Aristiidae) were associated with filamentous algae at a depth of 20 m.Both represent the first report for a blue hole and the amphipod constitutes the first record of the genus for Cuba and theCaribbean Sea. Three other isopods, i.e. Gnathostenetroides sp., Cirolana parva, and Cirolana crenulitelson, and the cumacean Procampylaspis sp. are documented for the first time from the same blue hole.

Two New Species

The genus Anisoderomorpha Arrow, 1925 (Coleoptera: Erotylidae: Languriinae) is redescribed and two new species of Anisoderomorpha are described: A. tamdaoensis sp. nov. from Vietnam and A. malayana sp. nov. from Malaysia. The adults of A. tamdaoensis sp. nov. were found to be sexually dimorphic in external morphology, particularly in the shape of the head and mandibles: females have a large asymmetrical head and mandibles, whereas males have a symmetrical head with slightly asymmetrical mandibles. All three members of Anisoderomorpha and its related taxon, Celolanguria curvipes Arrow, 1925, are illustrated and the host plant of Anisoderomorpha is predicted based on the morphological similarity of the specified mouthparts to those of other genera.
