Quadrasura Holloway, 2001 , Moths of Borneo 7: 365 (Type species: Asura ktimuna van Eecke, 1920 , by original designation).

Diagnosis. Small moths with yellow colouration and diffuse pattern. The type species of the genus resembles externally some members of the genus Miltochrista . The male genitalia are characterised by (1) the presence of large lateral subapical lobes of tegumen (am autapomorphic feature); (2) the most part of tegumen being fused (an autapomorphic feature); (3) the vinculum having two short lateral processes and a shallow medial concavity; (4) the narrow valva with short costa having a short trigonal medial process but no distal process; (5) the presence of a well-developed distal saccular process; (6) the broad aedeagus with the vesica being tubular basally and comma-like curved distally, weakly granulated and bearing a small, blunt, plate-like cornutus subbasally.

Female is unknown.

Distribution. Endemic of Borneo Island.

Number of species. The genus is monobasic.
