摘要

The snakefly genus Sininocellia is one of the most enigmatic groups in Inocelliidae, with an obscure phylogenetic status due to lack of male adults. A newly discovered male adult of Sininocellia gigantos Yang is described, representing the first male of this genus. Additionally, a new species, Sininocellia chikun sp. n., is described based on two females from central China. The phylogenetic relationships between Sininocellia and other relatives as well as the biogeography are discussed.
