Rhyparia largeteaui Oberthür, 1884 , Études ent. 10: 32, pl. 1, fig. 5. holotype ♂, China: Kouy-Tchéou. Euryobeidia largeteaui: Fletcher, 1979 , The Generic Names of Moths of the World, 3: 84.

Diagnosis. Forewing length: male 19–23 mm; female 2 1–23 mm. Externally, E. largeteaui is extremely similar to E. quadrata . But it can be distinguished by the following characters: the forewing upperside of E. largeteaui is entirely orange-yellow, while in E. quadrata , it is white at posterior base. In the male genitalia, the dorsal process of the uncus is smaller and less developed than in E. quadrata ; the small process at the tip of the costa is more pointed in E. largeteaui ; the aedeagus of E. largeteaui ends in a long, strongly sclerotized and hook-like process, whereas it ends in a broad sclerite in E. quadrata . In the female genitalia, the lamella antevaginalis of E. largeteaui is a triangular sclerite instead of approximately two semicircle sclerites in E. quadrata , and the lamella postvaginalis is absent or tiny in E. largeteaui but developed in E. quadrata .

Remarks. Oberthür (1884) described this species as Rhyparia largeteaui , without mentioning the number or the sex of the specimens he had at hand for description. He figured one specimen on plate 1, as fig. 5 (probably a male), mentioned the origin of the species as “Kouy-Tchéou” (Kweitschou, Guizhou) and the discoverer as “M. (onsieur) L’ abbé Largeteau”. Exactly this is written on the locality label of one male specimen kept in the collection of ZFMK. In addition, there is a hand-written label attached, denoting the determination and the publication-data “(Etud. d’Ent., X e liv sn Pl.1, fig.5)”. Wehrli later dissected this specimen (genitalia slide no. 5518) and referred to its structures in the generic description of Euryobeidia Wehrli, 1939 .

Wehrli purchased the Palearctic Geometridae out of the collection Charles Oberthür, the larger part (remaining Geometridae and all other families of Lepidoptera ) went to the NHM, London. We studied –besides many other parts– the material of E. largeteaui at the collection of NHM, but did not find another specimen with label-data like those mentioned above.

So we consider the specimen in the collection of ZFMK as the only existing type, a holotype by monotypy.
