JOINT MEETING OF ICHTHYOLOGISTS AND HERPETOLOGISTS
7th INTERNATIONAL MEETING ON MESOZOIC FISHES
Systematics and Paleobiogeographic Patterns
1 - 7 August 2017
The Palaeontological Research and Education Centre in cooperation with the Faculty of Science of Mahasarakham University (Thailand), the University Claude Bernard Lyon 1 (France), and the Natural History Museum of Geneva (Switzerland) are pleased to announce and host the 7th INTERNATIONAL MEETING ON MESOZOIC FISHES. The meeting is dedicated to reflect the progress in Mesozoic fish research that has been accomplished in the past 25 years since the first meeting in 1993, to discuss old and new methodologies, and to present novel information about the evolution, diversification, and the palaeobiogeography of fishes during the Mesozoic.
Registration should be open November 3rd.

|TAXONOMIC NEWS/ NEW SPECIES
EBERT, D.A. & PAPASTAMATIOU, Y.P. & KAJIURA, S.M. & WETHERBEE, B.M. (2017):Etmopterus lailae sp. nov., a new lanternshark (Squaliformes: Etmopteridae) from the Northwestern Hawaiian Islands. Zootaxa, 4237 (2): 371–382
New species: Etmopterus lailae
Abstract: A new species of lanternshark, Etmopterus lailae (Squaliformes: Etmopteridae), is described from the Northwestern Hawaiian Islands, in the central North Pacific Ocean. The new species resembles other members of the “Etmopterus lucifer” clade in having linear rows of dermal denticles, and most closely resembles E. lucifer from Japan. The new species occurs along insular slopes around seamounts at depths between 314–384 m. It can be distinguished from other members of the E. lucifer clade by a combination of characteristics, including a longer anterior flank marking branch, arrangement of dermal denticles on the ventral snout surface and body, flank and caudal markings, and meristic counts including number of spiral valve turns, and precaudal vertebrate. A key to species of the Etmopterus lucifer-clade is included.
DALLARES, S. & CARRASSON, M. & SCHAEFFNER, B.C. (2017): Revision of the family Sphyriocephalidae Pintner, 1913 (Cestoda: Trypanorhyncha), with the description of Heterosphyriocephalus encarnae n. sp and redescriptions of two species of Sphyriocephalus. Parasitology International, 66 (1): 843–862
New species: Heterosphyriocephalus encarnae
Abstract: The family Sphyriocephalidae Pintner, 1913, which comprises the genera Hepatoxylon Bosc, 1811, Sphyriocephalus Pintner, 1913 and Heterosphyriocephalus Palm, 2004, is revised from newly-collected and museum material. Heterosphyriocephalus encarnae n. sp. is described from the pelagic thresher, Alopias pelagicus Nakamura (Lamniformes: Alopiidae) collected from the Pacific Ocean off Boca del Alamo, Mexico. This species can be readily distinguished from the rest of sphyriocephalids by its small size, low number of proglottids and long velum with a characteristically irregular and folded border, among other features. The tentacles show a distinctive basal armature, and a heteroacanthous typical metabasal armature with heteromorphous hooks. Redescriptions are provided for Sphyriocephalus tergestinus Pintner, 1913 and S. viridis (Wagener, 1854) Pintner 1913 based on novel morphological data. A phylogenetic analysis including the available sequences of sphyriocephalid species plus new generated sequences of S. tergestinus has been performed, from which S. tergestinus is allocated into Heterosphyriocephalus as H. tergestinus n. comb. New dichotomous keys for the determination of genera of Sphyriocephalidae are provided, as well as new generic diagnoses for Sphyriocephalus and Heterosphyriocephalus and keys for the determination of species within both genera. Although the morphology of the genus Hepatoxylon is not addressed in the present study, the available sequence of the type-species has been incorporated in the phylogenetic analysis and its relationship to the other two genera of the family is discussed.
