Two new species belonging to the genus Glaucocharis Meyrick, 1938 are described from southwest China: Glaucocharis sperlingi sp. n. and G. nussi sp. n. The female of G. castaneus Song & Chen, 2002 is described for the first time. The geographical distribution of the genus in China is analysed. The precipitation of the warmest quarter is revealed to be the strongest predictor affecting the present distribution pattern of the genus. A map showing the distribution of the known Chinese localities of Glaucocharis is provided.

The genus Glaucocharis, one of the most species-rich genera of the subfamily Crambinae (Lepidoptera, Crambidae), was established by
Morphologically, the members of the genus can be recognized by characters of the forewing: the apex usually with an apical mark, the termen below the apex with an indentation reaching the tip of M1, and well-developed marginal spots. In the wing pattern, Glaucocharis is similar to Roxita Bleszynski, but can be distinguished by the forewing with a well-developed M1 and the valva without a ventral fold in the male genitalia; in Roxita, M1 in the forewing is absent and the ventral fold of the valva is often present (
In the present paper, two species of Glaucocharis are described from the Mabian Dafengding National Nature Reserve, southwest of China. The geographical pattern of distribution presented by the genus in China is also commented upon.
All specimens were collected at night with a mercury-vapour lamp. The specimens were hand-collected alive and killed by ammonium hydroxide just prior to mounting and spreading as shown in
The distribution of Glaucocharis was analysed using MaxEnt (
Holotype ♂: CHINA: Mabian Dafengding National Nature Reserve, Mabian (28°51'N, 103°31'E), Sichuan Province, 1100 m, 12.viii.2012, coll. Wei-Chun Li, prep. gen, WD16102 (JXAUM).
Paratype, 1 ♂, with same locality as holotype and collected on 10.viii.2012 (JXAUM).
This new species is similar to Glaucocharis electra (Bleszynski) by having slender uncus and gnathos, and thin and long valva in the male genitalia. It can be distinguished by the basal process of the costa of the valva with two projections, the juxta ending with three spine-like projections, and the phallus with a line of tiny spine-like cornuti in the male genitalia (Fig.

Unknown except that the moths are in flight in early August and come to light. The habitat in which this species has been collected is located at 1100 m altitude, at the foot of the mountain. Most parts of the mountain are covered with trees belonging to families Lauraceae and Fagaceae (Fig.

Paratype, 1 ♂, with same locality as holotype and collected on 10.viii.2012, prep. gen. WD16100 (JXAUM).
This species can be distinguished from its congeners by the unique characters in the male genitalia. The costal projection is absent and the phallus has a single strong spine-like cornutus (Fig.

In honour of Dr Matthias Nuss, who contributed profoundly to systematic research on pyraloid moths, and who maintains and expands the most important tool for taxonomic information on the world pyraloid species: GlobIZ (www.pyraloidea.org).
The generic assignment of G. nussi is primarily based on the external characters. However, its male genitalia are atypical for Glaucocharis. Characters of both sexes and molecular data would have to be analysed phylogenetically to provide a more insightful hypothesis concerning its classification.

At present, all Glaucocharis species in China occur in humid–semi-humid areas (pale blue to green), which can be separated from arid–semi-arid areas (dark blue) in western China by using the climate data Bio18 (Fig.
