Bocula sejuncta


Diagnosis.
The forewings are rather weakly marked, fawn, with an irregular, partially indistinct submarginal of small black chevrons (see next species also), and there is some sexual dimorphism, males having a much darker hindwing with a buff (concolorous with the forewing) hair pencil along the costa.

Taxonomic note. There is some variation through the range in the structure of the male abdomen, particularly in the breadth versus length of the eighth sternite (narrower in Borneo than in India), the shape of its apical flanges (parallelogram-shaped in Borneo, more rounded in India), and in the more distal saccular process of the valve (distinctly digitate in Borneo). The aedeagus and vesica are also variable in width. Material from Queensland (expansilis; slide 18680) was closer in these features to the Indian male syntype (slide 18682) dissected. The situation merits further study through dissection from other localities. Related species are B. nigropunctata Warren (Solomons) with ssp. magna Warren (Trobriand Is.), and B. limbata Butler (Christmas I., Indian Ocean).

Geographical range. Indian Subregion, Borneo, Sumbawa, Sulawesi, New Guinea, Queensland.

Habitat preference. Material from recent surveys consists of a male from lowland alluvial forest at 70m near G. Mulu, and single females from upper montane forest at 1790m on G. Mulu and from the edge of lowland dipterocarp forest at 100m by the Danum Valley Field Centre in Sabah.

Biology. Bell (MS) reared the larva in India. It is cylindrical, with reduction of prolegs on A3 and A4, particularly the former. The colour is a uniform, light green, slightly yellowed at the segment margins. There is a lateral yellow line running the length of the larva.

It lives on the underside of leaves, skeletonising them from the edges, and walks with a looping motion. Pupation is in a silken cell within an enfolded leaf on the tree or on the ground. The pupa is slim and lacks a powdery bloom.

The host plant recorded was
Pongamia (Leguminosae).
