Abstract
Ivela yini sp. nov., is described from Guangdong, China based on morphological characters and molecular data. Adults, including genitalia and wing venation, and pupa are illustrated and compared to those of similar species. A key to Chinese Ivela species is provided. Assignment of the new species to Ivela Swinhoe is based primarily on a molecular phylogenetic analysis and is corroborated by morphology. Life histories of I. yini and Dendrophleps semihyalina Hampson are discussed.

Ivela yini Xie & Wang, sp. nov.
Diagnosis: This new species is diagnosed by a combination of characters. Superficially, the thorax and abdomen of the adult are white without black markings (Figs 3–6, 9, 10), the palpi are white (Fig. 11), and the forelegs are orange with white rings on the tarsal segments (Figs 9–11). In the male, the asymmetrical valvae are wide and truncated, with a deeply concave cucullus (Fig. 15). The uncus of I. yini (Fig. 15) is more than twice as long as the uncus of I. auripes (Fig. 17) and I. ochropoda (Inoue 1956: fig. 25). The female corpus bursae of I. yini has a pair of caudal projections (Fig. 16). The pupa has white hairs on the prothorax, on segments A2 and A3, and near the posterior end (Figs 21–24).
Etymology: The species is named after Ran Yin, who discovered the pupa of the new species. The name is in the genitive case.
