A new, Neotropical species of Acanthocyclops (Copepoda: Cyclopoida: Cyclopidae) Naturalis
Reid, Janet W.; Suárez-Morales, Eduardo.
Acanthocyclops smithae, a new species of cyclopoid copepod and a member of the A. vernalis-robustus group, is described from Honduras and southeastern Mexico. The few previous records of species of Acanthocyclops in tropical latitudes apparently refer to isolated populations of a few widespread temperate species. Acanthocyclops smithae is the only known exclusively tropical member of the genus.

A new species of Cymbasoma (Copepoda: Monstrilloida) from the Sulu Sea, Philippines Naturalis
Suárez-Morales, E..
A specimen of a monstrilloid copepod collected by the U.S. Fisheries Steamer “Albatross“ in the Sulu Sea, west coast of Mindanao, Philippines, and deposited in the U.S. National Museum of Natural History, was taxonomically restudied. The specimen had been originally identified as a male of Monstrilla serricornis Sars by C.B. Wilson. Reexamination revealed that the specimen represents a new species of the genus Cymbasoma, C. mcalicei. This species can be distinguished by its body proportions and body size, but mainly by the structure of the genital lappets, which have a serrated posterior margin unique in the genus. This is the seventh species of Cymbasoma reported from East or Southeast Asia.

A new species of Hemicyclops (Crustacea, Copepoda, Poecilostomatoida, Clausidiidae) associated with hermit crabs in Curaçao Naturalis
Stock, Jan H..
STOCK, J. H. 1992. A new species of Hemicyclops (Crustacea, Copepoda, Poecilostomatoida, Clausidiidae) associated with hermit crabs in Curaçao. Stud. Nat. Hist. Caribbean Region 71, Amsterdam 1992: 69-78. Hemicyclops geminatus n. sp. is described from the upper infralittoral zone of Curaçao (Antilles). It is a regular associate of three species of hermit crabs: Calcinus tibicen, Paguristes grayi, and Dardanus venosus. The new taxon appears to be a twin species of Hemicyclops columnaris HUMES, 1984, an associate of a stony coral off the Pacific coast of Panamá.

Allocation of Laophonte trispinosa Sewell to Xanthilaophonte gen. nov. and the description of X. carcinicola spec. nov. (Harpacticoida: Laophontidae) Naturalis
Fiers, F..
Laophonte trispinosa Sewell is reported here from various localities in the Indian and the West Pacific Ocean, and is allocated to the herein erected genus Xanthilaophonte gen. nov. A second species, X. carcinicola spec. nov. is described from Indon »sia. The genus Xanthilaophonte gen. nov. is most closely related with Echinolaophonte Nicholls. Both species of this genus live in association with decapods, mainly Xanthidae, and occur on the carapax of their hosts, between the bristles. Comparison of the copepodid development clearly shows that the advanced morphology of Xanthilaophonte gen. nov. resulted from heterochrony events.

Amsterdam Expeditions to the West Indian Islands, Report 64. A new family of harpacticoid copepods and an analysis of the phylogenetic relationships within the Laophontoidea T. Scott Naturalis
Huys, Rony.
A new family Cristacoxidae is proposed to accommodate the monotypic genera Cristacoxa gen. nov., Noodtorthopsyllus Lang (ex Canthocamptidae) and Cubanocleta Petkovski (ex Laophontidae). Cristacoxa petkovskii gen. et spec. nov. is described on the basis of a single male collected from coralline sand of Bonaire, West Indies. N. psammophilus Noodt and C. noodti Petkovski are redescribed and refigured on the basis of new material from the Galápagos (Isla Santa Cruz), the West Indian Islands (Curaçao, Klein Curaçao, Bonaire) and the Canary Islands (El Hierro, Tenerife). The new family is characterised by the presence of an outer spinous process on the first antennular segment, the absence of the antennary exopod, the uniramous mandibular palp, the presence of...

Biochemical substrates expenses and respiration at short-term starvation of marine planktonic animals ArchiMer
Pavlova, Z; Morozova, A; Gaudy, R; Shchepkin, V.
One of the most important indices at estimation of productivity characteristics of hydrobionts is oxygen consumed in the process of respiration. Usually respiration (standard metabolism) is measured in small-volume respirometres (30-50 ml) where animals' activity is considerably restricted. It may underestimate respiration in comparison to natural one. Therefore respirometres of larger volume were used. Simultaneously under same conditions we tried to estimate energy requirements by expense of main biochemical components of organic matter (lipids, protein, glycogen). Results were used to calculate energy budget and to compare energy expenditures, measured according to consumed oxygen and tissue substrates expense.

Biologie du copepode Lernaeenicus sprattae Sowerby, 1806) et ses actions pathogenes sur les populations de sardines des cotes du Languedoc-Roussillon. ArchiMer
El Gharbi, Salwa; Rousset, Viviane; Raibaut, André.
Lernaeenicus sprattae is a blood-feeding copepod parasite of the pilchard, Sardian pilchardus . The larval stages of L. sprattae attach to the skin or the fins of the larval fish when the fish enter the lagoons. The mature, and in some cases ovigerous females of L.sprattae seek out the base of the fins or directly implant in the eye of juvenile or adult pilchards. The copepod has a particularly serious effect at the site of infection: its feeding has a severe effect on the fish. The pilchard returns to its breeding grounds in the open sea at the end of summer; this migration allows the copepod to complete its reproductive cycle and a new cycle of infestation is able to begin.

Cases of niche-partitioning and of habitat-segregation in pelagic marine calanoids of the genus Euchirella (Crustacea: Copepoda) Naturalis
Vaupel Klein, J.C. von.
Two cases of apparent niche-partitioning and one case of alleged habitat-segregation in the calanoid copepod genus Euchirella are described. These are examined with regard to their possible implications for making generalizations about the structure of biocoenoses and about mechanisms of speciation in the pelagic marine environment.

Concordance patterns in zooplankton assemblages in the UHE - Luís Eduardo Magalhães reservoir in the Mid-Tocantins river, Tocantins State, Brazil - doi: 10.4025/actascibiolsci.v33i2.7336 Biological Sciences
Bessa, Gisele Fernandes; Universidade Federal do Tocantins; Vieira, Ludgero Cardoso Galli; Universidade de Brasília; Bini, Luis Mauricio; Universidade Federal do Goiás; Reis, Deusiano Florêncio dos; Universidade Federal do Tocantins; Morais, Paula Benevides de; Universidade Federal do Tocantins.
The goal of this study was to evaluate the concordance amongst three zooplankton groups (Rotifera, Cladocera, and Copepoda) and between the zooplankton groups and the environmental variables in the Luis Eduardo Magalhães reservoir, in the Mid-Tocantins River, Tocantins State, Brazil. Concordance patterns were found in relation to environmental variables, cladocerans, and rotifers, although values were relatively low. These results indicate that one should be cautious about the use of indicative taxonomic groups to detect environmental changes, where divergent results annul extrapolation possibilities and indicate the existence of distinct environmental factors controlling different groups.
