Baptini
Genus Guides
2Baptini is a tribe of geometer moths within the Ennominae, Geometridae. The tribe comprises approximately 19 distributed primarily across the Old World tropics and subtropics, including Asia and Africa. Members of this tribe exhibit diverse wing patterns, with some genera such as Euryobeidia displaying pronounced mimicry of other lepidopteran groups. The tribe has been subject to taxonomic revision based on both morphological characters and molecular data.

Identification
Identification to tribe level requires examination of genitalic and wing venation patterns. Within Ennominae, Baptini can be distinguished by specific combinations of male and female genitalia structures, though precise diagnostic characters vary by . Some genera, particularly Euryobeidia, are notable for mimetic wing patterns featuring arrangements of dark spots that resemble other groups.

Distribution
Old World distribution centered on tropical and subtropical Asia, with records from China (including Hainan, Yunnan, Hubei, Sichuan, Fujian, Gansu, Hunan, Guizhou), Vietnam, Nepal, and Japan. Some extend into other regions; specific ranges vary considerably among constituent genera.
Behavior
Mimicry has been documented in at least one (Euryobeidia), where display wing patterns with numerous dark spots arranged in patterns that resemble other lepidopteran . The adaptive significance and specific models of this mimicry have been briefly discussed in taxonomic literature.
