Diagnosis.

The species is most closely related to S. bombycinus , but is considerably smaller. The male of S. brahma is characterised by its characteristic prosternal plate, which is structurally similar to that of S. bombycinus , and by a small elongate swelling in the midline on the upper part of the frons ( Blackman 1943: fig. 12).

Host.

This species is polyphagous attacking a wide range of host trees in many families, including: Cryptocarya wightiana Thwaites ( Lauraceae ), Ilex dipyrena Wall. ( Aquifoliaceae ), Swietenia mahagoni (L.) Jacq. ( Meliaceae ) (Wood 1992), Erythrina subumbrans (Hassk.) Merr. ( Leguminosae ), Hevea brasiliensis (Willd. ex A. Juss.) Muell. Arg. ( Euphorbiaceae ), Theobroma cacao L. ( Sterculiaceae ), Vernonia arborea Buch.-Ham. ( Compositae ) ( Kalshoven 1959).
