Morphological and molecular affinities of two East Asian species of Stenhelia (Crustacea, Copepoda, Harpacticoida)
Definition of monophyletic supraspecific units in the harpacticoid subfamily Stenheliinae Brady, 1880 has been considered problematic and hindered by the lack of molecular or morphology based phylogenies, as well as by incomplete original descriptions of many species. Presence of a modified seta on the fifth leg endopod has been suggested recently as a synapomorphy of eight species comprising t...
متن کاملThree new species of Parastenocarididae (Crustacea, Copepoda, Harpacticoida) from India.
To date, only 16 species of the very diverse family Parastenocarididae have been reported from the Indian subcontinent. This paper gives an illustrated description of three new species, viz. Parastenocaris edakkal n. sp., Proserpinicaris corgosinhoi n. sp., and Proserpinicaris karanovici n. sp., and discusses their position in the respective genera. While the first two species were found sympat...
متن کاملSystematics of the genus Heterolaophonte (Crustacea, Copepoda, Harpacticoida), with redescription of H. uncinata and H. curvata.
Both sexes of Heterolaophonte uncinata (Cherniavski, 1868) and H. curvata (Douwe, 1929) are redescribed based on newly collected material from the Black Sea and Mediterranean coasts of Turkey in view of the fact that there has been no detailed redescription since their original descriptions. Neotypes are also designated for both species. Detailed comparisons of the characters displayed among He...
متن کاملA new species of Peltidium Philippi, 1839 (Crustacea, Copepoda, Harpacticoida) from the Pacific coast of Mexico
During the analysis of phytal meiobenthic samples collected from a rocky-sandy beach in the state of Nayarit, in the Mexican Pacific, several specimens of harpacticoid copepods were obtained and taxonomically examined. These specimens were found to represent an undescribed species of the peltidiid genus Peltidium Philippi, 1839. The new species, Peltidium nayarit sp. n. is described herein. It ...
متن کاملDiversity and distribution of the free-living freshwater Cyclopoida (Copepoda: Crustacea) in the Neotropics.
Cyclopoida species from the Neotropics are listed and their distributions are commented. The results showed 148 species in the Neotropics, where 83 species were recorded in the northern region (above upon Equator) and 110 species in the southern region (below the Equator). Species richness and endemism are related more to the number of specialists than to environmental complexity. New researche...
