13mm,
 14mm. This species has
facies, including narrow brown
patches, more or less as in the next species, but with a white area at the
hindwing apex as in partita. The male genitalia indicate affinity to partita
rather than the other two, but the saccus is distinctively narrowed, the
apical part of the gnathus is shorter and the outward flexure of the socii is
more marked.
Holotype BRUNEI:
0m, S.
Selanjak, 4464, 1432, mangrove, 8-9.iii.1984 (Maj.
T.P.G. Helps), BM geometrid slide 8607.
Paratypes: 2 (slide 8626), 1 as holotype but 4463,
1432, 6-7.iii.1984.
Geographical range. Borneo, Singapore.
Habitat preference. All records are from mangrove forest.
Biology. Murphy (1990) described the biology in
Singapore and illustrated the larva. It is variegated brown with prominent
lateral flanges on thoracic segments and dorsal abdominal tubercles to which
plant fragments are attached.
It usually feeds on the flowers of the only recorded
host-plant, Avicennia alba (Avicenniaceae), an important mangrove tree.
