A new Arietellidae (Copepoda: Calanoida) from the Red Sea

A new species of the calanoid copepod genus Paramisophria T. Scott, 1897 is described from the Egyptian sublittoral zone of the Red Sea. Paramisophria aegypti sp. nov. appears to be closely related to the species Paramisophria ammophila and Paramisophria platysoma. Paramisophria aegypti differs from P. ammophila in having two unequal lateral setae plus one long terminal process and two tiny equal lateral setae plus one long terminal process on the third exopodal segment on the male right and left fifth legs (vs three terminal processes increasing in size inward on both male fifth legs). Paramisophria aegypti can be distinguished from P. platysoma in the following characters: prosome symmetrical (vs extreme asymmetry); third exopod segment of the right leg completely separated from the second segment and bears two unequal lateral setae plus one long terminal process (vs partially fused to the second segment and bears four terminal processes increasing in size inward); third exopod segment of the left leg with two lateral setules and one long terminal process (vs two lateral setules, one short outer medial process and one long terminal process); endopodal lobes of the female legs 5 bear one long plumose seta (vs setae are lacking).http://www.zoobank.org/urn:lsid:zoobank.org:pub:C0A92BF9-2306-4A35-AA39-CE3B5865A396     

Annelids (Polychaeta and Oligochaeta) from the Sea of Marmara,with descriptions of five new species

This paper deals with annelids (Oligochaeta and Polychaeta) collected in the Sea of Marmara between 2006 and 2010 at depths from 0 to 66 m. A total of five oligochaete and 198 polychaete species were found. Five polychaete species, namely Prosphaerosyllis marmarae sp. nov., Levinsenia demiri sp. nov., Levinsenia kosswigi sp. nov., Levinsenia marmarensis sp. nov. and Levinsenia tribranchiata sp. nov. are new to science, and five oligochaete and 84 polychaete species are new to the fauna of the Sea of Marmara. A list of species found in the region and their maximum densities are presented at depth intervals. The present material includes six alien polychaete species, Paraprionospio coora, Polydora cornuta, Prionospio (Minuspio) pulchra, Pseudopolydora paucibranchiata, Chaetozone corona and Metasychis gotoi, of which the latter four species were new records for the region.     

Two new species of Enoplida (Nematoda) from the Yellow Sea,China

Two new species of free‐living marine nematodes Adoncholaimus chinensis sp. nov. and Bathylaimus huanghaiensis sp. nov. from the Yellow Sea, China are described and illustrated. Adoncholaimus chinensis sp. nov. is characterized by the gubernaculum with a slender apophysis; two files of seven to eight circumcloacal setae on each subventral side of body. Bathylaimus huanghaiensis sp. nov. is characterized by a cylindrical body and smooth cutical. The buccal cavity is relatively smaller than in other species of the genus Bathylaimus. The anterior buccal cavity has only one obvious dorsal tooth. The amphids are subspiral with 1.2 turns, posterior to the base of posterior buccal cavity. They also have a long three‐jointed cephalic seta.     

Sillago suezensis,a new whiting from the northern Red Sea,and status of Sillago erythraea Cuvier (Teleostei: Sillaginidae)

The status of Sillago erythraea Cuvier in Cuvier and Valenciennes 1829 is re-examined. A lectotype designation by McKay in 1985 fixes it as a junior synonym of Sillago sihama (Forsskål in Niebuhr, 1775), which is restricted to the southern Red Sea. Northern Red Sea populations previously assigned to S. sihama or S. erythraea, are here described as Sillago suezensis sp. nov. Sillago suezensis is also distributed in the eastern Mediterranean Sea due to Lessepsian immigration through the Suez Canal. The new species is characterized within the Sillago sihama group, which has the swimbladder divided posteriorly into two tapering extensions projecting below the vertebral column extending into the tail musculature, by the absence of scales on the preopercle and on most of the opercle, a total number of 34 vertebrae, the swimbladder with lateral extensions each spreading a blind tubule anterolaterally, and a low position of the nostril.

Two new free-living marine nematode species of the genus Pseudosteineria (Monohysterida: Xyalidae) from the Yellow Sea,China

Two new species of free-living marine nematode, Pseudosteineria sinica sp. nov. and Pseudosteineria zhangi sp. nov., from the Yellow Sea, China are described. Pseudosteineria sinica sp. nov. is characterized by body spindle-shaped, cuticle distinctly annulated; amphidial fovea not visible; spicules unequal in length, the longer one divided into two sections jointed in the middle, the shorter one simple, without indentation; both spicules curved with proximal capitulum, tapered distally; gubernaculum with a dorso-caudal apophysis. Pseudosteineria zhangi sp. nov. is characterized by eight groups of relatively short subcephalic setae; amphidial fovea circular, lying at level of grouped subcephalic setae; spicules paired, equal in length, dissimilar in shape; right spicule slender, left one with a large manubrium proximally; gubernaculum bucket-shaped, with a dorsal apophysis. A key to species is provided for the 13 valid species of the genus.     

Three new species of the genus Belbolla (Nematoda: Enoplida: Enchelidiidae) from the Yellow Sea,China

Three new species of free‐living marine nematodes of the genus Belbolla: Belbolla huanghaiensis sp. nov., Belbolla stenocephalum sp. nov. and Belbolla warwicki sp. nov. from the Yellow Sea, China, are described and illustrated. Belbolla huanghaiensis can be separated from other species in the Belbolla genus by the number of oesophageal bulbs (nine), the length of the spicules and gubernacular apophysis, and the size of the two winged precloacal supplements. Belbolla stenocephalum can be separated from other species by the number of oesophageal bulbs (eight), the length of the spicules and the structure of gubernacular apophysis. Belbolla warwicki sp. nov. is characterized by the number of oesophageal bulbs (seven), reduced precloacal supplements and the structure of gubernacular apophysis. A key to the genus Belbolla is provided to facilitate species identification. Types are deposited in the College of Life Science and Technology, Ocean University of China.     

Polychaetes (Annelida: Polychaeta) from the Aegean and Levantine coasts of Turkey,with descriptions of two new species

In this paper, soft-bottom polychaete species collected in August and September 2011 in the Aegean and Levantine Seas (4–325 m) are presented. A total of 358 species belonging to 48 families were found. Two species, Leonnates aylaoberi sp. nov. and Levinsenia materi sp. nov., are new to science and 14 species are new records for the marine fauna of Turkey. Syllidae and Spionidae were represented by a high number of species. The highest polychaete density was estimated as 5660 ind.m^?2 in the area. The most dominant species in the area were Lumbrineris geldiayi, Owenia fusiformis and Sigambra tentaculata. A total of 21 alien polychaete species were encountered in the area, of which Streblospio gynobranchiata formed a dense population in the Aegean Sea (Izmir Bay), and Prionospio depauperata and Prionospio saccifera in the Levantine Sea. Four hot spot areas for the settlement of alien species were determined in the area.

Alien polychaete species (Annelida: Polychaeta) on the southern coast of Turkey (Levantine Sea,eastern Mediterranean), with 13 new records for the Mediterranean Sea

The examination of benthic material collected from different depths and habitats along the southern coast of Turkey (Levantine Sea, eastern Mediterranean) in September and October 2005 revealed 30 alien polychaete species belonging to 15 families. Thirteen species (Pisione guanche, Linopherus canariensis, Onuphis eremita oculata, Lumbrineris perkinsi, Dorvillea similis, Timarete caribous, Pherusa parmata, Pherusa saldanha, Streblosoma comatus, Polycirrus twisti, Laonome triangularis, Branchiomma bairdi and Janua steueri) are new to the Mediterranean fauna, 24 species are new to the Turkish fauna and 27 species are new to the Levantine coast of Turkey. The specimens collected from the Levantine coast of Turkey and northern Cyprus that were previously identified as Linopherus acarunculata and Branchiomma boholense are reidentified as L. canariensis and B. bairdi, respectively. In the light of present knowledge, the previous reports of Lumbrineris inflata and Streblosoma hesslei from the Mediterranean (Italian coast) could refer to the species L. perkinsi and S. comatus, respectively. The species new to the Mediterranean Sea are redescribed and discussed.     

A new subgenus Parastegana (Allstegana) (Diptera,Drosophilidae), with descriptions of two new species from South China

A new subgenus Allstegana is established within the genus Parastegana, including two known and two new species from southern China: P. (A.) maculipennis (Okada, 1971), P. (A.) drosophiloides (Toda and Peng, 1992 Toda, M. J. and Peng, T. X. 1992. Some species of the subfamily Steganinae (Diptera: Drosophilidae) from Guangdong Province, southern China.. Annales de la Société Entomologique de France (N.S.), 28: 201–213. [Web of Science ®] , [Google Scholar]), P. (A.) brevivena Chen and Zhang, sp. nov., and P. (A.) punctalata Chen and Watabe, sp. nov. A key to all known species of Parastegana is provided.     

The Hypselodoris infucata,H. obscura and H. saintvincentius species complex (Mollusca,Nudibranchia, Chromodorididae), with remarks on the genus Brachychlanis Ehrenberg, 1831

The Indo-Pacific species Hypselodoris infucata (Rüppell and Leuckart, 1830) and Hypselodoris obscura (Stimpson, 1855) have been regarded as distinct by most authors. In this paper, numerous specimens with the colour pattern described for both H. infucata and H. obscura, and collected from localities comprising the geographic range of both nominal species, have been examined and anatomically studied. All specimens from south-east Australia, the type locality of H. obscura, consistently have a very long ejaculatory portion of the vas deferens, whereas in specimens collected from other Indo-Pacific localities this portion is very short. There are no other major morphological or anatomical differences between H. infucata and H. obscura. It is not clear whether H. obscura and H. infucata are different species, but since there is at least a consistent anatomical difference between them, they are provisionally regarded as distinct. The reproductive system, radula and external morphology are extremely variable among specimens of H. infucata. Specimens from Indo-Pacific localities other than south-east Australia, even those externally similar to H. obscura, belong to H. infucata. Hypselodoris saintvincentius Burn, 1962, which has been regarded as a synonym of H. infucata, is clearly distinguishable by the external coloration, reproductive system and radular morphology. Phylogenetic evidence indicates that H. saintvincentius is the sister species of H. infucata and H. obscura. A re-examination of the holotype of the uncertain species Brachychlanis pantherina Ehrenberg, 1831 revealed that it is conspecific with Hypselodoris infucata. Therefore, the name Brachychlanis Ehrenberg, 1831, which has not been used for more than 50 years, has preference over the widely used name, Hypselodoris Stimpson, 1855. In order to preserve nomenclatural stability invalidation of the name Brachychlanis is proposed.     

Two new free-living marine nematode species of Chromadoridae (Nematoda: Chromadorida) from the Yellow Sea,China

Two new species of free-living marine nematodes, Ptycholaimellus ocellatus sp. nov. and Prochromadorella gracilis sp. nov. from the Yellow Sea, China are described. Ptycholaimellus ocellatus sp. nov. is characterized by the presence of ocelli, an abruptly narrowing anterior cervical region, a cuticle with transverse rows of punctations, a lateral differentiation with two longitudinal rows of thick elongate dots, and voluminous ventral gland with a large ampulla. Prochromadorella gracila sp. nov. is characterized by the combination of lateral differentiations in the anterior pharyngeal region, a small conical stoma with outstretched teeth, slit-like amphidial fovea, and five pre-cloacal supplements.     

Swedish nemerteans (phylum Nemertea), with description of a new hoplonemertean genus and species

A survey of the nemertean fauna along the Swedish west coast found specimens of 20 genera and 32 species, of which one genus and species is new to science (Tetraneuronemertes lovgreni gen. et sp. n.). The proportions of the three taxa Hoplonemertea, Heteronemertea, and Palaeonemertea are 34, 55, and 11%, respectively, with respect to specimen numbers, and the proportions for species within these taxa are 53, 31 and 16%, respectively. The most common species encountered during the survey were the heteronemerteans Lineus bilineatus, Micrura fasciolata, and Micrura purpurea, the hoplonemertean Nipponnemertes pulcher, and the palaeonemertean Cephalothrix rufifrons.     

Revision of Zaphanta Dyar, 1910 (Lepidoptera: Mimallonidae: Zaphantinae), with descriptions of nine new species

ABSTRACT

A genus of small, yellow mimallonid moths, Zaphanta Dyar, is revised. This genus has been shown to be sister to the remainder of Mimallonidae, and therefore has been placed in its own monogeneric subfamily, Zaphantinae St Laurent and Kawahara. Long considered monotypic or bitypic, Zaphanta have not been the focus of any systematic treatment. The moths belonging to this genus are found throughout Central and South America, and detailed examination of several disparate, as well as sympatric, populations of Zaphanta have revealed numerous undescribed species all of similar appearance, but with distinct male genitalia, which we describe here. We redescribe Z. infantilis Dyar and Z. fraterna Schaus, and describe the females of both for the first time. An additional nine new species are described and figured from the Amazon, Cerrado and Atlantic Forest: Z. acuta sp. nov., Z. anas sp. nov., Z. bahiana sp. nov., Z. beckeri sp. nov., Z. elephanta sp. nov., Z. elephanticula sp. nov., Z. machaera sp. nov., Z. rawlinsi sp. nov. and Z. stiletto sp. nov. One of these, Z. beckeri, may be extremely imperilled due to deforestation.

Aspects of mangal ecology along the Red Sea coast of Saudi Arabia

Surveys of the mangal along the Red Sea coast of Saudi Arabia form the basis of this study. Both soft-bottomed mangals and the less well known hard-bottomed mangals are represented. The distribution of Avicennia marina, the dominant mangrove species, is discontinuous in the northern part of the Red Sea. Its development increases southwards, and mean height is inversely correlated both with latitude (P<0·05) and salinity (P<0·05). Another species, Rhizophora mucronata, was recorded in only five areas. Molluscs and crabs represent the principal faunal elements within the mangal. The density of Cerithidea cingulata, the dominant mollusc species, shows significant correlation (P<0·01) with the abundance of blue-green algae. Four species of fiddler crab (Uca) are included among the crab fauna of the mangal, one of which (U. urvillei) is here newly recorded for the Red Sea. Evidence is given for suggesting that the mangal biota in the region sampled may not be distinctive. Rather, it consists of many species found not only within the mangal but also in other habitats such as seagrass beds and even rock beaches. It is suggested that the mangal of the Red Sea represents a composite habitat, containing both hard and soft substrates and inhabited by species typical of each. This contrasts with the situation in most other mangals studied.     

Cirolanid isopod crustaceans from the Townsville region of Queensland,Australia, with descriptions of six new species

Summary

A wide variety of littoral and sublittoral marine habitats have been sampled in the vicinity of Townsville in N.E. Australia in order to assess the diversity of cirolanid isopods present.

Of the thirteen species represented in the collections six were previously undescribed. The species present were: Cirolana schioedtei Miers, 1884 (16m in mud/sand); C. pustulosa Hale, 1925 (mainly littoral habitats such as crevices in wooden installations); C. cranchii var. australiense Hale, 1925 (mainly littoral cryptic habitats); C. tumulosa sp. nov. (3–9 m in soft particulate substrata); C. arcicauda sp. nov. (3–10 m in soft particulate substrata); C. variguberna sp. nov. (2–18 m in soft particulate substrata); C. luticola sp. nov. (2–14 m in soft particulate substrata); Neocirolana bicrista sp. nov. (11 m in particulate substrata); Excirolana orientalis Dana, 1853 (littoral sand); Pseudolana concinna (Hale, 1925) (littoral sand); Pseudolana brevifimbria sp. nov. (littoral sand); Eurydice orientalis Hansen, 1890 (plankton and 5–11 m in soft particulate substrata); Eurydice inermis Hansen, 1890 (plankton and 2–11 m in soft particulate substrata).

The new species are described in detail and additional information is given on the other species—some of which have been poorly described in the past. In addition two closely related species, i.e. Cirolana tenuistylis Miers, 1884 and C. woodjonesi Hale, 1924 are also redescribed so as to avoid any confusion with the Townsville species.     

Heteromysoides (Crustacea: Mysidacea: Heteromysini) from a submarine cave on Grand Cayman,the Caribbean Sea: descriptions of a new and a rare species

During a recent biological investigation of submarine caves of Grand Cayman, the Caribbean Sea, two species of Heteromysoides were collected. One species, referred to Heteromysoides spongicola B?cescu, 1968 Baˇcescu, M, 1968. Heteromysini nouveaux des eaux cubaines: trois espèces nouvelles de Heteromysis et Heteromysoides spongicola n. g. n. sp., Revue Roumaine de Biologie, Zoologie 13 (1968), pp. 221–237. [Google Scholar], is known only by the type specimens; therefore, this discovery marks the second record of occurrence and a new habitat record for the species. The other species is considered new and is described as H. stenoura, a 10th species of the genus. The new species closely resembles H. simplex Hanamura and Kase, 2001 Hanamura, Y, and Kase, T, 2001. A new species of Heteromysoides (Mysidacea: Mysidae) from submarine caves of Okinawa, southwestern Japan, with a key to the world species, Crustacean Research 30 (2001), pp. 65–71.[Crossref] , [Google Scholar], known from the submarine caves of Okinawa, north-western Pacific, in the possession of a spiniform process on the eyes and a simple termination to the third thoracic endopod. However, the new species can be readily distinguished from the Pacific congener by a distally narrow telson and a more developed cornea in the eyes.
