中文摘要	The lack of data concerning the morphology of male cladocerans greatly impedes our understanding of the systematics of cladocerans. This is because the differentiation of males is of significant importance for distinguishing closely related species. Simocephalus himalayensis himalayensis Chiang & Chen, 1974 (Cladocera, Simocephalus) is an endemic cladoceran species in the Tibetan plateau, China. To date, no information has been available regarding the morphology and biology of its males. In this study, we provide the morphological and biological data of the males that were produced in laboratory populations. The male individuals are about 1.01-1.20 mm long; the margin of antennulae possess two sensory papilla; dorsal valve margin smooth. Two vas deferens are located between the supra-anal angle and the proximal anal teeth. Sperm is round with a diameter of two micrometers. An updated morphological description and reproductive data of the females of this species are also provided.
