Neocyclops Gurney from Brazilian sandy beaches (Copepoda: Cyclopoida) Naturalis
Lotufo, Guilherme Ribeiro; Falavigna da Rocha, Carlos Eduardo.
Neocyclops medius Herbst, 1955 and Neocyclops vicinus (Herbst, 1955) are redescribed from intertidal interstitial water of sandy beaches along the Brazilian coast. The male of N. vicinus is described for the first time. Neocyclops vicinus can be easily distinguished from N. medius by the relatively longer caudal rami, the presence of a mandibular palp, and the sexually dimorphic antenna. This study revealed the leg 4 endopodite segments 2 and 3 as being fused in both species. The terminal segment of the 2-segmented leg 4 endopodite of the copepodite 5 does not differentiate into 2 distinct segments during the molt to adult. The plane of fusion is marked by a thin and incomplete line on the frontal surface. This scar was erroneously interpreted as a...

Copepods from intertidal interstitial water of Salvador, Brazil. I. Cuipora janaina gen. n., sp. n. & Cyclopina caiala sp. n. (Cyclopoida: Cyclopinidae) Naturalis
Lotufo, Guilherme Ribeiro; Falavigna da Rocha, Carlos Eduardo.
Cuipora janaina gen. n., sp. n., and Cyclopina caiala sp. n. are described from the interstitial water of a sandy beach in Salvador, Bahia (Brazil). Cuipora is distinguished from all other genera of the subfamily Cyclopininae in having the endopodite of legs 1-4 2-segmented and the terminal segment armed with 4 setae. Cuipora is compared to Erythropolites Huys & Boxshall, 1990, Herbstina Huys & Boxshall, 1990, and Cyclopina Claus, 1862, with which it has most morphological similarities. Cyclopina caiala sp. n. is distinguished by the structure of the leg 5 of the male and female and by a particular combination of characters of the mouthparts. Taxonomical problems involving Cylopina mediterranea Steuer, 1940 are discussed.
