Diacyclops languidus (Sars, 1863), a cyclopoid copepod previously unrecorded in North America, was found during a survey of Crustacea occurring in temporary aquatic pools which support populations of mosquito larvae. A detailed description of the species is given with notes on its phenology, ecology, and distribution in the bogs of Basse-Mauricie, Québec.

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 of parasitic copepod occurring in western North America is described, Ergasilus nerkae n. sp. An emendation of E. turgidus Fraser, 1920 and a redescription of E. auritus Markevich, 1940 are presented. A total of four species resembling E. caeruleus (E. turgidus, E. confusus Bere, 1931, E. auritus, and E. nerkae) have so far been described, and characters to distinguish the species of this group are given.

Copepoda Cyclopoida

The freshwater copepod Mesocyclops Sar, 1914, a species-rich genus within the family Cyclopoidae Rafinesque, 1815, is common in tropical areas. In addition, the genus members are used for the biological control of mosquito larvae (Anopheles, Aedes) which are vectors for transmitting dengue fever. In Vietnam, a total of 11 Mesocyclops species have been recorded in inland freshwater bodies. Of which, one endemic species (M. sondoongensis Tran & Hołyńska, 2015) and two species were described from Vietnam, namely M. yenae Hołyńska, 1998; M. ferjemurami Hołyńska & Vu, 2000. Diagnostic characteristics, habitat, and distribution of all 11 species are provided. Additionally, a pictorial key to all Vietnamese Mesocyclops is presented.

Provisional Identification

Examination of material of five cyclopoid copepod genera found in Ontario fresh waters and a comparison with species of these genera from other parts of the world closely related to Ontario species has given some very interesting results. The widespread Ectocyclops phaleratus was the species previously recorded from Ontario. However, the Ontario material fits the description of E. polyspinosus Harada, 1931, known from Taiwan. There is considerable confusion in the nomenclature of North American species of Eucyclops. In Ontario Eucyclops serrulatus is found. This widespread and variable species needs revision on the basis of worldwide material. Hence, only a provisional identification can be made now. The species previously called E. speratus in Ontario is a hitherto underscribed species, E. neomacruroides, closely related to, but we think distinct from, E. macruroides and E. speratus. The third species is Eucyclops macruroides denticulatus and the fourth is the very distinctive E. prionophorus. In the genus Tropocyclops, besides the widely occurring Tropocyclops prasinus prasinus, T. extensus was found. This latter species has been consistently identified as T. prasinus mexicanus since 1959. Four species of the genus Acanthocyclops occur in Ontario. Acanthocyclops robustus is very common; A. vernalis is rare and so are A. venustoides and A. carolinianus. We are unable to resolve the status of A. venustoides bispinosus, as only late copepodid stages of this species, and no mature adults, are available. Mesocyclops americanus, long called M. leuckarti, is now a well-documented species, much rarer than the somewhat atypical (for the genus) M. edax, well known in North America. Our proposed designations for North American species are summarized. There is a need to collect material year round from all available biotopes to document the species composition of Ontario Copepoda. Our work is also a first step in clarifying the status of North American Copepoda, comparing material from North America and elsewhere.

Copepoda Cyclopoida

A study of the life history of the cyclopoid copepod Cyclops scutifer Sars in a small lake of the Matamek River System, Quebec, indicates a 1-year life cycle with four cohorts produced annually. The primary cohort overwinters as early nauplii and reaches maturity during midsummer when it spawns the primary cohort of the succeeding year. The other cohorts may merge with either each other or the primary cohort and contribute somewhat less to the overall cycle. Slower development of copepodites of the second cohort in 1976 may have been the result of an inadequate number of naupliar prey from the calanoid copepod Diaptomus minutus.

Copepoda Cyclopoida

The postembryonic development of a species of the cyclopoid copepod genus Corycaeus from Saanich Inlet, British Columbia, is described and illustrated. Specimens were obtained from a large (40 000/m3) population of Corycaeus which developed in the control (unperturbated) enclosure of a Controlled Ecosystem Pollution Experiment studying the effects of copper on marine ecosystems. Population dynamics of the species in the 1700-m3 enclosed water columns are discussed.
