Copepoda Cyclopoida

Plankton samples obtained from the Ciénaga Grande de Santa Marta, an extensive estuarine system in northern Colombia, yielded adult male and female specimens of an undescribed halicyclopine cyclopid copepod of the genus Halicyclops. Cyclopid copepods are frequently found in freshwater and transitional habitats. Members of the subfamily Halicyclopinae are chiefly brackish water forms with a few freshwater species. The new species described herein is assignable to the group of species “F” of Halicyclops (sensu Pesce, 2018) with a 2333 exopodal spine formula. Currently, this group contains five species and one subspecies. Halicyclops gutierrezi sp. n. can be distinguished from its known congeners by the absence of an anal operculum, the relative length of setae of the female and male P5, the relative length of the inner setae of P4EXP3, and details of the male antennule. This is the fifth species of Halicyclops recorded from Colombia and the first one of Halicyclops group “F” described from the Caribbean region. With the addition of H. gutierrezi sp. n., the number of species of the genus known from the Neotropics increased to 20. A key to the species of the genus recorded in Colombia is also provided.

A New Species

During 1996–1997 a systematic sampling programme was carried out in brackish coastal lakes and lagoons and in the delta of the River Po. In six of the nine collecting locations, 12 species of Gastrotricha were identified. One species, Chaetonotus ichthydioides, is new to science; another three species, the chaetonotidans Heterolepidoderma foliatum and the macrodasyidans Dendrodasys ponticus and Turbanella cf. pontica, and one macrodasyidan genus, Paradasys (P. subterraneus), were found in Italy for the first time. The unusual morphology of some of the species identified shows that Gastrotricha colonized brackish waters from both marine and freshwater habitats.

Abstract A new species of the cyclopoid copepod genus Paramacrochiron, P. tridentatum, which is parasitic on the rhizostome medusa, Versuriga anadyoneme (Maas, 1903), is described from Vietnam. This is the tenth species within the genus. The new species is distinguishable from other congeners by the combination of the following features: (1) female second maxillipedal segment with 3 acutely pointed processes terminally; (2) female leg 4 endopod as long as or slightly longer than exopod; (3) male maxilliped with a small, acutely pointed process at subterminal corner of the first segment and a row of relatively coarse spinules along the inner margin of the second segment. The present study most probably implies a high species diversity of Paramacrochiron in the tropical and subtropical waters of the Indo-West Pacific region.

A New Species

Abstract A new species of the thermosbaenacean genus Tethysbaena Wagner,1994 is described as T. ledoyeri n. sp. Together with an as yet undescribed amphipod (Niphargus sp.) it is an inhabitant of the brackish water of an aquifer that flows through the Basse-Provence Urgonian karstic system and reaches the Mediterranean Sea, 15 km east of Marseille, in the “Calanques” coast. The new taxon, being part of the T. argentarii-group, is compared with its closest allies in this group. Preliminary DNA data obtained from two specimens of the new species provide confirmation of its close ties to T. argentarii but also to T. scabra, the two geographically closest described species.

A New Species

A new species of rajin skate, Zearaja maugeana sp. nov., is described on the basis of specimens from two estuaries in remote southwestern Tasmania. The species, known locally as the Maugean Skate, has been assessed as Endangered in the IUCN Red List of Threatened Animals based on its rarity and very narrow geographic range. It is also one of the few skates worldwide to occur mainly in brackish water. The Maugean Skate belongs to a group of anatomically conservative, Dipturus-like skates conforming to the currently unrecognized genus Zearaja Whitley. This ancient group, with a Gondwanan lineage possibly dating back to the Cretaceous, contains at least two other species: Z. nasuta from New Zealand and Z. chilensis from South America. The skeletal morphologies of the Zearaja species are compared with typical Dipturus skates and their phylogenetic position discussed.

Rybocyclops Dussart, 1982 is a little-known stygobitic genus, hitherto represented by its type and only species, R. pauliani (Lindberg, 1954), from Madagascar. A second species, named Rybocyclops dussarti sp. nov., is described herein from an agricultural bore-well in southeastern India. The new species has a unique combination of morphological characters, which, inter alia, include: genital double-somite enlarged; anal operculum moderately large; furcal rami somewhat outcurved and about twice as long as wide; female antennules 11-segmented; legs 1–4 with spine formula 2.2.2.2, and setal formula 5.5.5.4; legs 1 and 4 without seta on inner margin of coxa and basis; leg 4 male with one seta more than in female on second endopodal segment; leg 5 fused to somite and represented by vague protuberance, bearing three setae; and leg 6 reduced to two setae. The generic diagnosis is partially amended for accommodating the new species. The discovery of R. dussarti sp. nov. is of much biogeographic interest because it is the first record of Rybocyclops from Asia and only the second freshwater stygobitic cyclopoid taxon from India, with apparent Gondwanan distribution.
