Several species of cyclopoid copepods were collected from improved and unimproved hang-dug-wells in the Republic of Bénin over the years 2009-2014. Fifty five wells located in seven different districts were sampled: 15 wells in the district of Pobé (Department Plateau) and 1 well in Kétou (Department Plateau), 4 wells in Porto-Novo District (Department Ouémé) and, 15 wells in Lokossa District (Department Mono),18 wells in Parakou District (Department Borgou), 1 well in Abomey-Calavi District (Department Atlantique) and 1 in Zogbodomè District (Department Zou). Among them, 4 new species of the genus Allocyclops Kiefer, 1932 were found and are described herein: Allocyclops spinifer sp. n., A. nudus sp. n., A. pilosus sp. n. and A. sakitii sp. n. They are compared with the three African species previously described. Allocyclops appears to be a sub-Saharan taxon specialized to thrive in the variable environment of subsoil aquifers in laterite deck beds. An identification key to the 7 different African Allocyclops species is provided. © Frank Fiers, Moïssou Lagnika. Source

Specimens attributable to the genus Nannopus and sampled on three intertidal mudflats e.g. Longyearbyen (Spitsbergen, Svalbard archipelago), the river banks of "De Schelde" in Belgium and from its estuary, the "Oosterschelde", in the Netherlands are compared. This revealed the presence of a series of specific features allowing the discrimination of different species: N. didelphis spec. nov., N. scaldicola spec. nov., N. procerus spec. nov. and N. hirsutus spec. nov. In view of this, the poor original description of Nannopus palustris Brady, 1880 is reinterpreted and compared with the few descriptions available and the materials studied herein. "Norwegian" specimens identified by Sars as N. palustris turn out to be conspecific with N. procerus spec. nov., N. flexibilis (Lilljeborg) is re-instated as a separate species with N. palustris tiberiadis Por, 1968, N. palustris sensu Sars, 1927, Damian-Georgescu, 1970, and Nannopus spec. Hemsen, 1952 as junior synonyms. Nannopus may turn out to comprise of two different phylogenetic lineages each sustained by derived character states exhibited in the structure of the leg 4 armature and the morphology of the male leg 6 and the male genital apparatus. © 2013 Elsevier GmbH.

In the process of inventorying the copepod collection assembled by P.A. Chappuis and hosted at the "Emil Racoviţǎ" Institute of Speleology (Cluj, Romania), part of his material originating from the US was located. In 5 vials and on 6 slides are representatives of 9 different species: 7 Harpacticoida and 2 Cyclopoida. A list of the species, numbers of specimens available, and their condition is presented. Some of them had to be annotated as syntypes. Most of the cyclopids mentioned were donated to F. Kiefer and are currently hosted in the collection at Karlsruhe, Germany. Three representatives of the genus Moraria T. & A. Scott 1893, namely M. cristata Chappuis 1929, M. affinis Chappuis 1927, and M. americana Chappuis 1927, the latter currently known as M. laurentica Willey 1927, are reexamined and redescribed. Their diagnostic features, compared to the other known New World Moraria species, are summarized in tabular form to facilitate identification. Source
