Gyrochus yunnanensis Wang 1984 [IZCAS] China.

Diagnosis.

The light color of the metasoma combined with the color pattern of the wings is sufficient to distinguish this species. Gyrochus nigripennis Enderlein 1920 and Gyrochus sumatransis Enderlein 1920, both from Indonesia (Sumatra), are similar and differ in the presence of more extensive melanic color especially on the metasoma. Gyrochus ornatipennis ( Cameron 1905) (New Combination for Disophrys ornatipennis Cameron 1905), from Borneo also has more melanic color. Gyrochus flavipennis ( Brullé 1846) (New Combination for Agathis flavipennis Brullé 1846), from Papua New Guinea, has fore wings that are completely yellow.

Gyrochus helvus Enderlein 1920, from Sumatra, has a similar pale body but the fore wing is completely yellow except some very weak infuscation restricted to the apex. Gyrochus guangensis Wang, from China also has the fore wing completely yellow.

Notes.

The five nominal species of Gyrochus differ almost exclusively in color pattern, particularly in the wings. Van Achterberg and Long (2010) illustrated a specimen from Vietnam with much darker wings than that of the holotype; however they hav e correctly identified the specimen. The specimen illustrated here from Thailand conforms much more closely to the coloration of the holotype.
