Background Lithistid demosponges, also known as rock sponges, are a polyphyletic group of sponges which are widely distributed. In the Northeast Atlantic (NEA), 17 species are known and the current knowledge on their distribution is mainly restricted to the Macaronesian islands. In the Mediterranean Sea, 14 species are recorded and generally found in marine caves. Methods Lithistids were sampled in nine NEA seamounts during the scientific expeditions Seamount 1 (1987) and Seamount 2 (1993) organized by the MNHN of Paris. Collected specimens were identified through the analyses of external and internal morphological characters using light and scanning electron microscopy, and compared with material from various museum collections as well as literature records. Results A total of 68 specimens were analysed and attributed to 17 species across two orders, seven families, and seven genera, representing new records of distribution. Ten of these species are new to science, viz. Neoschrammeniella inaequalis sp. nov., N. piserai sp. nov., N. pomponiae sp. nov., Discodermia arbor sp. nov., D. kellyae sp. nov., Macandrewia schusterae sp. nov., M. minima sp. nov., Exsuperantia levii sp. nov., Leiodermatium tuba sp. nov. and Siphonidium elongatus sp. nov., and are here described and illustrated. New bathymetric records were also found for D. ramifera, D. verrucosa and M. robusta. The Meteor seamount group has a higher species richness (15 species) compared to the Lusitanian seamount group (six species). The majority of the species had their distribution restricted to one seamount, and ten are only known from a single locality, but this can be a result of sample bias. Discussion The number of species shared between the seamounts and the Macaronesian islands is very reduced. The same pattern repeats between the NEA and Mediterranean Sea. This study demonstrates that NEA seamounts are ecosystems with a higher diversity of lithistids than previously thought, increasing the number of lithistids known to occur in the NEA and Mediterranean Sea from 26 to 36 species.

First Time

This is the first in a series of reports describing new records caught with circle hooks, a method only now being employed in exploratory fishing in Brazilian deep waters. Several new records of deep-water fishes were obtained with this equipment. In this paper we record for the first time the occurrence of two genera and species of Bramidae in Brazilian waters: the tropical pomfret Eumegistus brevorti and the keeltail pomfret Taractes rubescens. We also report on previously unnoticed collection records from preserved specimens of Pterycombus brama in museum collections, and the first capture of an adult bigscale pomfret Taractichthys longipinnis in Brazil. These new records increase the number of bramid species known from Brazilian waters to ten. The addition of P. brama to the Brazilian Bramidae makes the Southwestern Atlantic the only known area of the world where two species of Pterycombus are found together. Meristic, biometric, and new biological data are presented for Eumegistus brevorti. Some species of bramids are rather rare and even if well described in the literature there are morphological characters and behavioral aspects yet to be added. Herein we present detailed descriptions of some bramid species to add to their published descriptions. A key to the Western Atlantic Bramidae is provided.

The genus Hymeraphia currently comprises three species and all records of the genus are from the northeast Atlantic and the Mediterranean Sea. The present paper describes a new species, H. vaceleti sp. nov. from a deep-water canyon, off southwest Ireland. H. vaceleti sp. nov. is morphologically distinct from other Hymeraphia species and 28S rRNA sequences show substantial differences between our new species and other Hymeraphia spp. We present data on the prevalence of sponge species established on the basis of single specimens (singletons) or uniques (species only known from a single locality). We argue for the recognition of singletons for species that are rare or from habitats that are very difficult to survey or sample, such as the deep sea.

This paper describes rare Cardiomya species from Brazil which have been hitherto misidentified as Cardiomya cleryana (d’Orbigny, 1842) in literature or museum collections. Cardiomya minerva sp. nov. is proposed as new species and is characterized by its quadrangular shell, short and truncated rostrum, and external ornamentation composed of six radial ribs on the posterior half of the shell flank. Cardiomya striolata (Locard, 1897) described from the Mediterranean Sea and northwestern Atlantic Ocean, is reported from Brazil for the first time; although previously regarded as a junior synonym of Cardiomya costellata (Deshayes, 1835), it is herein considered as a full species and redescribed. This species is characterized by its trapezoidal shell flank, elongated rostrum, tapering towards the tip, and external ornamentation composed of 18–53 radial ribs, the 3–4 posterior ones being the strongest and more widely spaced. Other three previously unknown species are illustrated but not formally named due to the lack of well-preserved articulated shells.

New records of fish of the genus Abudefduf observed and photographed in the Lebanese coastal waters are reported in the paper. The individuals from photos were examined on the basis of visible external morphological characters and geographical location already known in the Mediterranean Sea, as well as compared with photos taken elsewhere in their natural environments from various origins. In agreement with that reported by other authors, a careful analysis of these photos shows uncertainties in the validity of the visual characters previously used to distinguish between the two congeners A. vaigiensis and A. saxatilis already reported in the Mediterranean Sea, and even their possible confusion with A. troschelii. In some individuals, new morphological features are emphasized and may provide visual evidence for the presence of Abudefduf cf. troschelii (Gill, 1862). Sympatry and possible hybridization are discussed.

AbstractKristianstads Vattenrike Biosphere Reserve [KVBR] is a UNESCO designated area of Sweden possessing high biological value. Although several studies on tardigrades inhabiting Sweden have been performed, the KVBR area has been neglected. The current study investigates the tardigrade fauna of five areas of the biosphere reserve and includes 34 samples of different substrates analysed quantitatively and qualitatively. In total, 33 species of tardigrades were found in the samples, including 22 new records for the Skåne region, 15 new records for Sweden, and four species new to science. Mesobiotus emiliae sp. nov., Xerobiotus gretae sp. nov., Itaquascon magnussoni sp. nov., and Thulinius gustavi sp. nov. were described with an integrative approach (when possible) using morphological characters (light, electron scanning, and confocal laser scanning microscopies) and molecular markers (ITS2, 18S, 28S, cox1). A new protocol to increase morphological data was developed recovering mounted specimens within old slides for SEM analysis. Emended diagnoses for the genus Itaquascon and the transfer of Platicrista itaquasconoide to the genus Meplitumen are proposed. This study enriches the knowledge of the tardigrade biodiversity both within the KVBR and in Sweden and contributes to the rapidly increasing number of tardigrade species reported worldwide. The 33 species identified in the KVBR area represents 28% of all water bear species found in Sweden so far. The restricted study areas and limited number of samples collected suggests that the KVBR is very rich of tardigrades.

The subfamily Acastinae contains a diverse group of barnacles that are obligate symbionts of sponges and alcyonacean and antipatharian corals. Integrating morphological and genetic (COI) data to compare against known species, this paper reports on nine species of sponge-inhabiting barnacles of the subfamily Acastinae, including three undescribed species (Acasta caveata sp. nov., Euacasta acutaflava sp. nov., and E. excoriatrix sp. nov.) and three species previously not recorded in Australian waters (A. sandwichi, Pectinoacasta cancellorum, and P. sculpturata). The new species are distinguished from similar species by a suite of morphological characters as well as genetic distances. A lectotype for Pectinoacasta cancellorum is designated. Sponge hosts were identified for all specimens where possible and are represented by 19 species from eight families and five orders.

We examined 308 specimens of the Indo-Pacific blenniid Omobranchus punctatus deposited in four museum collections, and analyzed data on their collection locations to assess its invasion on the Atlantic coast of Central and South America. This species occurs in shoreline estuarine and marine habitats in the Indo-West Pacific. Previous sampling and recent records in the Tropical West Atlantic from 1930 to 2004 produced 20 records for: Panamá, Colombia, Venezuela, Trinidad and Brazil. In this work, we provide data on 17 new records for the Gulfs of Venezuela and Paria in Venezuela, as well as four records for Maranhão and Pará states in NE Brazil. The temporal pattern of collections (1930 - 2009) and the proximity of most localities to ports and zones of ship traffic indicate that O. punctatus was initially introduced to the Atlantic by ships travelling from India to Trinidad. Within Brazil the introduction is linked to shipping connected to petroleum platforms. In Maranhão and Pará the introduction may have occurred as a result of fish sheltering in fouling on hulls of ships moving between ports around the mouth of the Amazon River. Alternatively, the spread of this species along of the American coast may reflect the expansion of the range of O. puntactus through larval dispersal in northward flowing currents. We recommend monitoring of this introduced species, and studies of its ecology in West Atlantic areas.

Investigation of a large collection of Neuroptera from Northeastern Nigeria stored untouched in alcohol for four decades in the National Museum of Natural History, Sofia, provided the opportunity to examine unpublished specimens and conduct a thorough review of published literature, establishing the first comprehensive inventory of Ascalaphidae, Palparidae, and Myrmeleontidae of Northeastern Nigeria to date. Specimens had been collected between 1976 and 1978 in Northeastern Nigeria, mostly in Jos City and Plateau State. Five species of Ascalaphidae, four of Palparidae, and 26 of Myrmeleontidae were identified. Bankisus beroni sp. n. and Creoleon nigrithorax sp. n. are described. Gymnoleon gaillardi is not considered a synonym of Gymnoleon exilis and a new synonymy is established: Gymnoleon externus (Navás, 1911) (= Gymnoleon gaillardi Navás, 1912, syn. n.). An examination of unpublished specimens in museum collections and an exhaustive literature review were conducted in order to draw up a comprehensive inventory of the fauna of Northeastern Nigeria, which to date comprises 11 species of Ascalaphidae, 12 species of Palparidae, and 34 species of Myrmeleontidae, of which one species of Ascalaphidae, two species of Palparidae, and 16 species of Myrmeleontidae, as well as the genera Brevibarbis, Bankisus, and Capicua, had not been reported to occur in Nigeria. The chorological information on the genus Bankisus is reviewed, the ranges of the species are critically discussed and corrected, and all known localities are indicated on a map. Bankisus oculatus is reported for the first time from the Democratic Republic of the Congo. The first recording of Centroclisis lineatipennis in West Africa is reported. Palpares cataractae and Palpares radiatus are deleted from the list of Nigerian fauna. With these new records, the known ranges of eight species are extended by more than 1400 km. In the process of assessing the geographical distribution of species present in Northeastern Nigeria, six species, as well as the genera Myrmecaelurus and Cueta and the tribe Nesoleontini, are reported for the first time from Burkina Faso.

Celaenorrhinus pyrrha de Nicéville, 1889, a rare species of Hesperiidae previously known to be distributed from northeastern India to Indochina, is reported from southwestern Yunnan and southwestern Chongqing, China. A 658 bp COI gene sequence of this species is published for the first time. Although Chongqing is obviously isolated from the main distribution range, morphological characters of the specimens from this locality do not indicate a subspecies differentiation. Another rare taxon, C. munda munda (Moore, 1884), is also recorded from China for the first time based upon a male specimen from Cuona County in the Tibet Autonomous Region. This is the second specimen of C. munda from China, over 100 years after the holotype of C. munda joka Evans, 1949. The genitalia of both species are illustrated and described. Some taxonomic notes and a distribution map are provided as well.
