The species diversity of Copepoda Harpacticoida at several sampling locations in the Southern Atlantic has been investigated. From the obtained multicorer samples, a new taxon of Paranannopinae Por, 1986, Nyxis rostrocularis gen. nov., sp. nov., has been collected, which is described in the present paper. Specimens of the taxon have been encountered in the Angola Basin (DIVA 1 stations 325 and ...

The family Phyllognathopodidae (Crustacea, Copepoda, Harpacticoida) is heavily affected by the floating taxonomic status of the type-genus Phyllognathopus. A revision of the different character states displayed by members of the family is presented, and new phylogenetically informative characters are described, enlarging the analysis to the remaining genera of the family, Parbatocamptus and All...

A new species of harpacticoid, Parastenocaris distincta sp. nov., is described and discussed. The new species was collected in a freshwater interstitial habitat near the mouth of a river in Western Mindoro Province, the Philippines. This is the second species of Parastenocaris described from this country. The medial ornamentation of P1 basis, the morphology of male P3 and the number and distrib...

The discovery of two new species of Harpacticoida (Crustacea, Copepoda), Echinocletodes voightae sp. nov. (Ancorabolidae Sars, 1909) and Cletodes meyerorum sp. nov. (Cletodidae T. Scott, 1905 sensu Por, 1986), permitted a phylogenetic re-examination of the genus Echinocletodes Lang, 1936, whose membership in Ancorabolidae has been increasingly queried in the past decade. Echinocletodes voightae...

A new species, Strongylacron glabrum sp. n. is described from intertidal mudflats in the Korean peninsula. The new species is assigned to the monospecific genus Strongylacron Gee & Huys, 1996 in accordance with the generic morphological features of the rostrum, antennary exopod, and thoracic legs. However, Strongylacron glabrum sp. n. is clearly distinguished from the type species, Strongylacro...

Hans U. Dahms, Supawadee Chullasorn, Pawana Kangtia, Frank D. Ferrari, and Jiang-Shiou Hwang (2007) Naupliar development of Tigriopus japonicus Mori, 1932 (Copepoda: Harpacticidae). Zoological Studies 46(6): 746-759. Six naupliar stages of Tigriopus japonicus Mori, 1932 are described from the rocky coast off Keelung, northeastern Taiwan. A key for the identification of stages is provided. Naupl...
