Journ. Bombay nat. Hist. Soc. 17: 147 (Macrernis); Clarke. 1965: 60. TL; Sri Lanka, Maskeliya. [BMNH].

Diagnosis. The species is similar to F. verticosa Meyrick, but it can be distinguished by the absence of the brownish oblique fascia below the discal cell and beyond two thirds of the forewing. The male genitalia are also distinguished by having the median process on the ventral margin of the valva and the median lobe of the juxta. The female is known for the first time.
