Mecodina viridacea sp. n.
18-20mm. The facies is similar to that of A. cineracea Butler (Japan, Taiwan, China, N.E. Himalaya), but is distinguished by a narrower, more triangular costal mark from the submarginal, more distinctly darker transverse marking in the medial to postmedial area and, immediately distal to the more dentate submarginals of fore- and hindwings, a suffusion, also dentate, of pale yellow-green. Just interior to the hindwing submarginal is a fine, dark, gently curved fascia. This is more distant and more diffuse in cineracea. The genitalia differ from those of cineracea in being relatively smaller, with the valves more ovate. The aedeagus vesica lacks the central bundle of stout cornuti that is present in cineracea.

Mecodina viridacea

Holotype . SARAWAK: Kuching, Semengok (E.W. Classey), BM noctuid slide 18369.

Paratype . BRUNEI: Labi, LP 309, 5 Nov 1978, MV light (Allen).

Geographical range. Borneo, Sumatra (HS / ZSM), Java.

Habitat preference. Both specimens are from localities with lowland forest.

Biology. The larva of the related cineracea has been illustrated by Mutuura et al. (1983) and by Sugi (1987). It is rather stout, leaf-green, with all prolegs present, and strongly tapered from A8 backwards. A series of four paler yellowish green longitudinal bands is spaced evenly down each side to the line of the black spiracles; the bands decrease in width and become more broken in this sequence.

The host plant (Miyata, 1983; Sugi, 1987) is
Ficus (Moraceae).
