Holotype: Kalimantan Selatan, Pulo Laut. The holotype of Brixia citrina Hampson, 1897:625 from Kalimantan Selatan (Pulo Laut) is in the NHM (Mi7392).

Description

The pale lemon yellow colour of this species is very variable and liable to fade soon after capture to a pale fawn. R. sulphurea Warren, 1898 is similar but is a much brighter yellow with purplish red sub-basal fascia and a purple brown spotting on the FW. The pink tinged veins R5, M1& M2 near the FW apex are present and usually obvious in both spp. but are underlain by a purple/brown suffusion in R.sulphurea. On the Un these veins are much more brightly coloured and the FW cell has a group of blue-green scales in its basal half.
