Rusicada albitibia

. The forewings are a vinous grey-brown, sometimes with orange suffusion. In the male genitalia the central subapical projection of the valve is transverse as in combinans, but the juxta is rounded, entire apically, not distinctly bilobed.

Geographical range. Indian Subregion to Japan, Queensland and the Solomons.

Habitat preference. No records have been made in recent surveys but there are two specimens from the low-lying island of Pulo Laut in BMNH.

Biology. The species has been reared in the Solomons by Bigger (1988, pers. comm.), who illustrated and described the larva. The head is pale bluish green with faint whitish green reticulated mottling. The body is a pale slightly bluish green with the posterior margins of most segments yellow. There is a thin yellow, interrupted mid-dorsal line and similar lateral lines above and below spiracles, and a dorsolateral line. There are numerous pale yellow spots around the setal bases and elsewhere; the setae arise from black spots (brownish on abdominal segments posterior to the seventh). The spiracles are straw-coloured within a thin black outer ring. The thoracic legs are pale and the crochets on the prolegs brown. A description by Moore (1884-1887) attributed to nigritarsis may also be of the larva of albitibia (see p. 234).

The host-plant recorded by Bigger was
Hibiscus (Malvaceae).
