Godonela translineata


Diagnosis.
This is a smaller, more delicate species than avitusaria. The forewing postmedial is more distinctly angled, with darker shading on each side of the angle. The forewing margin is straight but that of the hindwing has a more definite tail at M3.

Taxonomic notes. This species is externally indistinguishable from G. emersaria Walker comb. n. from India and flies with it in N. Thailand (Bšnziger & Fletcher, 1988). The ventral portion of the valve is broad, square-ended in emersaria but tapering to a narrow rounded apex in translineata. The holotype of translineata (UM, Oxford) has the wrong abdomen glued on, hence another Sulawesi male matched with it (slide 13891) was examined. There is little difference in genitalic features between specimens from Thailand and Sulawesi, hence hollowayi is placed as a synonym of translineata. A male from Seram had somewhat intermediate genitalia, so the status of taxa such as albibrunnea Warren (Tenimber) needs clarification: externally they resemble emersaria. In Sumatra the emersaria-like taxon is slightly larger, and the male genitalia (slide 13892) have a squarer cleft between the arms of the valves: the processes of the eighth sternite are more widely spaced.

Geographical range. Sulawesi, Borneo, ?Sumatra, Thailand.

Habitat preference. The species is frequently encountered in lowland forest but extends up to the lower montane zone.

Biology. Bell (MS) reared emersaria in India. The larva is of typical geometrid shape. The body surface is dull and, with the head, white with a greenish tinge and rusty freckling. The setal bases are black and ringed with rufous colour. The segment margins are yellowish.

The young larvae are peripatetic, but rest on the underside and edges of leaves, extended at 45 degrees in a slight curve from where supported by the claspers. Mortality due to spiders and parasitic Hymenoptera is high.

Bell recorded a climber in the genus Elaeagnus (Elaeagnaceae) as host- plant, but Bšnziger & Fletcher noted it as reared from Delonix (Leguminosae) in Thailand. The Bornean species has been reared from Paraserianthes falcataria (Leguminosae) by Mr Chey Vun Khen and colleagues at the Forest Research Centre, Sepilok.
