5th International Whale Shark Conference (IWSC5) from 28-31 May 2019
From 28-31 May 2019, the town of Exmouth in the Ningaloo Coast World Heritage Area will welcome delegates to the 5thInternational Whale Shark Conference (IWSC5), a meeting of the world’s leading whale shark scientists, conservationists, natural resource managers and tourism managers. This is the fifth such conference to be held, following on from the successful IWSC4 held in Doha, Qatar in 2016. This meeting is timed to showcase Ningaloo’s world’s best practice whale shark management program and will follow the Ningaloo Whaleshark Festival, an annual community event that celebrates these magnificent animals. IWSC5 will bring together local scientists, researchers and postgraduate students to interact with international colleagues and collaborators to explore all aspects of whale shark biology and ecology and how this can translate to direct, on-ground conservation efforts. Delegates from around the world will be treated to four days of presentations, workshops, social functions and experiencing the world renowned Ningaloo whale shark tourism industry to forge new relationships and collaborations and debate ideas. A core focus of IWSC5 will be bringing together end users of the science being presented, such as tourism managers, marine park managers and conservation groups. This will improve the uptake and application of research and help develop collaborations between research scientists and managers and industry. For further information contact iwsc5@dbca.wa.gov.au.

TAXONOMIC NEWS/ NEW SPECIES

LAST, P.R. & SÉRET, B. & NAYLOR, G.J.P. (2019): Description of Rhinobatos ranongensis sp. nov. (Rhinopristiformes: Rhinobatidae) from the Andaman Sea and Bay of Bengal with a review of its northern Indian Ocean congeners. Zootaxa, 4576 (2): 257–287
New species: Rhinobatos ranongensis
Abstract: A new species of guitarfish, Rhinobatos ranongensis sp. nov., is described from 5 preserved specimens, and images and tissue samples of additional material, collected from the Andaman Sea and Bay of Bengal. This species co-occurs in the eastern sector of the northern Indian Ocean with two poorly defined congeners, R. annandaleiNorman and R. lionotus Norman, which have been misidentified and confused with Indo-Pacific congeners since they were first described in 1926. Norman’s species are rediagnosed based on limited new material and a re-examination of the types. In the western sector of the northern Indian Ocean, Rhinobatos annandalei has been confused in recent literature with the sympatric R. punctifer Compagno and Randall, which is represented by four primary colour morphs, including a white-spotted colour morph resembling R. annandalei. Rhinobatos punctifer also displays strong intraspecific variability and sexual dimorphism in some body dimensions. These four species of Rhinobatos have unique MtDna sequences and belong to a clade of Indo-West Pacific species that are morphologically similar. Despite the relatively small numbers of specimens available for investigation, these species exhibit some clear differences in body proportions, meristics and squamation. Rhinobatos ranongensissp. nov. differs from its northern Indian Ocean congeners through a combination of a relatively narrow disc and mouth, high vertebral count, long snout, low dorsal fins, and being largely plain coloured. A new lectotype and a paralectotype are designated for the syntypes of R. annandalei, and the four primary colour forms of R. punctifer, the plain, white-spotted and ocellated morphs, are described and the three nominal species rediagnosed. A key is provided to the four known members of the genus in the northern Indian Ocean.

RUIZ, C.F. & DRIGGERS, W.B. & BULLARD, S.A. (2019): A New Species of Neoalbionella (Copepoda: Siphonostomatoida: Lernaeopodidae) from Skin of the Gulper Shark, Centrophorus granulosus (Squaliformes: Centrophoridae) in the Northern Gulf of Mexico.Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 108 (1): 67-87
New species: Neoalbionella benzipirata
Abstract: Using light and scanning electron microscopy of male and female copepods, we herein describe a new species of NeoalbionellaÖzdikmen, 2008 (Copepoda: Lernaeopodidae), Neoalbionella benzipirata n. sp., infecting the skin of the gulper shark, Centrophorus granulosus (Bloch and Schneider, 1801), in the northern Gulf of Mexico. Females of the new species were assigned to Neoalbionella by having 3 setae on the maxillule lateral palp (vs. 2 setae in Lernaeopoda Nordmann, 1832) and a single accessory denticle on the maxilliped subchela claw (vs. ≥2 denticles in Lernaeopoda). Females of the new species resemble those of Neoalbionella longicaudata (Hansen, 1923) Özdikmen, 2008 but can be differentiated from them and those of all congeners by having a unique configuration of 16 dorsocephalic sensilla; an antennule terminal segment having 6 apical setae comprising tubercles 1 and 3, digitiform seta 4, 2 subequal setae of complex 5, and flagelliform seta 6; an antenna exopod with a thickened dorsal ridge, smooth (convex) outer surface with 2 short papillae, and rugose (concave) inner surface plus a terminal endopodal segment having a large dorsal hook, medial spine, bifid distal tubercle, and spinulose ventral process; a mandible having the formula P1, S1, P1, S1, P1, S1, B5; and a single pair of anterolateral spines on the mouth cone labium. Males attached to the posteroventral surface of the females' genital trunk were assigned to Neoalbionella by having tapered (not inflated) caudal rami directed posteroventrally. They were differentiated from previously reported congeneric males by having an antennule with the same number and configuration of apical setae as the female; an antenna with a spatulate exopod having minute spinules along its apex plus a terminal endopodal segment with components the same as the female; a mandible with formula P2, S1, P1, S1, B5; a labium with 1 pair of anterolateral spines like the female; and a conspicuous mediative process with bifid tip. Detail of the dorsocephalic shield (in females) and mouth cone labium (in both sexes) previously had not been used to diagnose Neoalbionella spp. We also dissected voucher specimens of “Neoalbionella longicaudata” (collected from gulper sharks in the western Pacific Ocean off Japan by Shiino in 1956), which we morphologically diagnosed as an innominate species, Neoalbionella sp. This is the first report of a species of Neoalbionella from the Gulf of Mexico and the second species of Neoalbionella reported from C. granulosus, a deepwater shark seldom encountered and surveyed for parasitology.
MALEKI, L. & MALEK, M. & RASTGOO, A. (2019): Acanthobothrium chabahariensis n. sp. (Cestoda: Onchoproteocephalidea) in the cowtail stingray Pastinachus cf. sephen (Myliobatiformes: Dasyatidae) from the Gulf of Oman, Iran. Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 108 (1): 67-87
New species: Acanthobothrium chabahariense
Abstract: A new species of genus Acanthobothrium Blanchard, 1848 is described from the spiral intestine of Pastinachus cf. sephen(Forsskal, 1775) from Iranian coasts of the Gulf of Oman. The morphological characteristics of specimens were analyzed with light and scanning electron microscopy. Acanthobothrium chabahariense n. sp. is a category 1 species (with <15mm total length, <50 proglottids, <80 testes and a symmetrical ovary) together with 48 other species. The new species was compared with species from the Western Indian Ocean and those reported from Pastinachus. It is distinguished from the other species from the region within the genus by a combination of the following morphological features: total length, number of proglottids, hook length, number of testes and ovarian lobe length. Pastinachus sephen is a complex group still with no taxonomic resolution; therefore, the identity of the host in this study area is in question. Because of the molecular study of specimens from the Gulf of Oman did not completely correspond with P. sephen since they were introduced as P. cf. sephen. This brings the total number of species of Acanthobothrium from Pastinachus to 11 and the total number of Acanthobothrium species described from the Persian Gulf and the Gulf of Oman to seven. In addition, an identification key to the Acanthobothrium species occurring in the Pastinachus species was provided.
KITAMURA, A. & OGAWA, K. (2019): Three species of Dendromonocotyle Hargis, 1955 (Monogenea: Monocotylidae) collected from Japanese rays. Systematic Parasitology, 96 (2): 233–243
New species: Dendromonocotyle tsutsumii, Dendromonocotyle fukushimaensis
Abstract: Eighteen species of Dendromonocotyle Hargis, 1955 (Monogenea: Monocotylidae) have so far been described from elasmobranchs worldwide. In this paper, two new species are described; Dendromonocotyle tsutsumii n. sp. from the skin of the Japanese eagle ray, Myliobatis tobijeiBleeker from Tokyo Bay and the pitted stingray, Dasyatis matsubarai Miyosi, from Ooarai, Ibaraki Prefecture, Japan, and Dendromonocotyle fukushimaensis n. sp. from the skin of the cow stingray, Dasyatis ushiei (Jordan & Hubbs) reared at an aquarium in Fukushima Prefecture, Japan. Dendromonocotyle tsutsumii is distinguished from the congeners by the presence of a sclerotised duct connecting the vagina with the seminal receptacle, and De. fukushimaensis by the large body size and the presence of a donut-shaped structure encircling the male copulatory organ near its distal end. Additionally, the reproductive system of Dendromonocotyle akajeii Ho & Perkins, 1980 is redescribed, based on specimens from the skin of the whip stingray, Hemitrygon akajei (Müller & Henle) (syn. Dasyatis akajei) caught in Hamana Lake, Shizuoka Prefecture, Japan. A key to the 20 species of Dendromonocotyle including the present new species is provided.
