Abstract

Cladoceran communities of two lakes of Nevado de Toluca Volcano, Central Mexico, were studied. A new species of Aloninae, Alona manueli sp. nov., is described. It was previously confused with Palearctic Alona intermedia Sars, 1862, but clearly differs from it in the morphology of postabdomen, head shield and head pores, and thoracic limbs. Position of Alona manueli sp. nov. within the genus is unclear, it did not belong to any species-group within Alona s. lato. Other species recorded in the studied lakes are Alona ossiani Sinev, 1998, Alonella pulchella Herrick, 1884, Chydorus belonging to sphaericus-group, Eurycercus longirostris Hann, 1982 and Pleuroxus cf. denticulatus Birge, 1879.

摘要

对墨西哥中部托卢卡内华达火山的两个湖泊中的枝角类群落进行了研究。描述了阿洛纳属（Aloninae）的一个新物种，即曼努埃利阿洛纳（Alona manueli sp. nov.）。它之前被误认为是1862年的古北区物种中间阿洛纳（Alona intermedia Sars），但在尾腹部、头甲和头部小孔以及胸肢的形态上明显与之不同。曼努埃利阿洛纳新物种在该属中的位置尚不清楚，它不属于广义阿洛纳属内的任何物种组。在所研究的湖泊中记录的其他物种有1998年的奥西亚尼阿洛纳（Alona ossiani Sinev）、1884年的美丽阿洛内拉（Alonella pulchella Herrick）、属于球棘溞组（sphaericus-group）的盘肠溞属（Chydorus）、1982年的长吻真尖额溞（Eurycercus longirostris Hann）以及疑似1879年的齿状褶纹溞（Pleuroxus cf. denticulatus Birge）。
