“Eilema” decreta Butler 
Lithosia decreta Butler, 1877, Trans. ent. Soc. London, 1877: 351.

"Eilema" decreta
(x 1.32)

Males are small, a pale dull yellow, though with the forewings distinctly darker, more orange, than the hindwings, and thus have some similarity with Tampea accepta Butler (see Tampea accepta Butler ) and Holocraspedon flava van Eecke ( see Holocraspedon flava van Eecke). The forewing venation is different, however, being typical of Eilema sensu lato. The male genitalia are also distinctive as discussed (see "Eilema" monochroa Turner stat. rev.) No candidate specimens for the female have been located.

Taxonomic note. The Australian taxon monochroa Turner, placed as a synonym of decreta in Nielsen et al. (1996), appears to be unrelated (see "Eilema" monochroa Turner stat. rev). Material in the BMNH series of decreta attributed to monochroa is congeneric with Brunia, the next genus discussed. The male genitalia of decreta are distinctive and atypical of Eilema even in its broadest sense, particularly the serrate distal margin of the valve, the bifid saccular process, and the spining and rod at the aedeagus apex. The next species has some of these features and may be related.

Geographical range. Borneo.

Habitat preference. The holotype male was taken in Sarawak by A.R. Wallace. A further male has been taken recently in lowland forest at Semongok, near Kuching, and there are three males from Sabah in the USNM: from 1530m 1km south of Kundasang on the slopes of G. Kinabalu; 20km east of Telupid; in the lowlands at Tenom.
