Nycteola indicatana

See mesoplaga above.

Taxonomic note. The other Indo-Australian species previously placed in Symitha, N.
nolalella Walker comb. n. (= N. albescens Wileman & West syn. n.) has a similar but less disjunct range to indicatana and may therefore prove also to occur in Borneo. The facies is more as in mesoplaga but the insect is smaller with narrower forewings, the central costal grey area being quadrate rather than triangular, but less clearly distinguished. The male genitalia in nolalella are distinguished particularly by a tongue-like process forming the apex of each valve. Bornean indicatana appear referable to ssp. microdonta rather than the much darker, greyer ssp. parvella.

Geographical range. Indian Subregion (ssp. indicatana); Singapore, Borneo (ssp. microdonta); Java (ssp. parvella); ?Sulawesi, Dammer; Rennell I. (Solomons; ssp. ferrugana).

Habitat preference. Two specimens have been taken in the lowlands of Brunei, from Kampong Kiarang and the coastal locality of Kampong Kapok.

Biology. The K. Kiarang specimen was reared from Eugenia (Myrtaceae). N. nolalella has been reared from both Eugenia and Lagerstroemia (Lythraceae) (Yunus & Ho, 1980; Robinson et al., 2001). It was reared from the latter in India by Sevastopulo (1944). The body is pale green, the head more yellowish green. There are traces of a dark dorsal line, and the primary setae are white, arising from white dots. There is also a pale spiracular line. The larvae live semi-gregariously on young shoots that they cover with a slight web of silk. Pupation is in a canoe-shaped, pure white silken cocoon with a short fringe of erect threads around the flattened dorsal surface.
