. Bell (MS) reared dilectissima in India. The head is heart-shaped, smooth, watery chestnut brown with black setae. The body is shining, rather greasy-looking, broader centrally than at each end, with primary setae only, these set on distinctive long tubercles. The colour is rosy brown, with the anal segments and a spiracular band yellowish. Some of the hairs on the tubercles are white.
