Genus Daonymphes gen. n.

Type and only species.

Daonymphes bisulca sp. n.

Diagnosis.

Forewing broad proximally [strongly narrowed proximally in Liminympha ]; vast majority of proximal subcostal veinlets forked [simple in all other Mesozoic genera]; crossveins between branches of MP absent [present in Nymphites Haase, 1890, Mesonymphes Carpenter, 1929]; CuP space broad, nearly two times as wide as intracubital space [nearly as wide as intracubital space in Liminympha ].

Etymology.

From Daohugou, the locality of the type species, and Nymphes , a genus-group name. Gender: feminine.

Remarks.

This genus is most closely related to four other Mesozoic genera ( Nymphites , Mesonymphes , Liminympha and Sialium Westwood, 1854) but clearly distinguished from these as indicated in the diagnosis. The latter genus is only known from single hind wing from the early Berriasian of Purbeck, England. In general, Nymphidae occur very rare in the Jurassic, only six specimens are known. The monotypic genera Liminympha (Middle Jurassic [Bathonian/Callovian] of Daohugou, China) and Mesonymphes (Late Jurassic [Tithonian] of Solnhofen, Germany) are represented by almost complete specimens possessing both fore- and hind wings. The type species of Nymphites from Solnhofen is represented by only two incomplete hind wings. Two species from Daohugou are assigned to this genus: one species (two specimens) have almost complete fore- and hind wings; the other only hind wings ( Shi et al. in press).
