The freshwater copepod genus <i>Mesocyclops </i> (Copepoda, Cyclopoida, Cyclopidae) in Vietnam

Abstract

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 &amp; Hołyńska, 2015) and two species were described from Vietnam, namely M. yenae Hołyńska, 1998; M. ferjemurami Hołyńska &amp; Vu, 2000. Diagnostic characteristics, habitat, and distribution of all 11 species are provided. Additionally, a pictorial key to all Vietnamese Mesocyclops is presented.

First record of the freshwater copepod Mesocyclops paranaensis Dussart & Frutos, 1986 (Copepoda: Cyclopoida: Cyclopidae) from Colombia

“…The widespread freshwater cyclopoid copepod genus Mesocyclops Sars, 1914 can be found in a wide variety of freshwater habitats, including temporal and permanent pods, lakes, rivers, swamps (Hołyńska et al 2003, Alekseev et al 2013, Papa and Hołyńska 2013, Fuentes-Reinés et al 2013, and even coastal hiposaline ponds (Suárez-Morales et al 1999). It is considered as a cosmopolitan group with greater affinity for tropical areas, especially in eutrophic water bodies (Luong et al 2020). This genus is one of the most speciose in the subfamily Cyclopinae; with nearly 80 valid species known (Papa & Hołyńska 2013, Tran & Hołyńska 2015, only 21 have been reported from the Neotropical region (Gutiérrez-Aguirre et al 2006, Suárez-Morales et al 2020.…”
