Mecodina poaphiloides Walker comb. n. 
Thermesia poaphiloides Walker, 1864, J. Proc. Linn. Soc. (Zool.) 7: 186.
Mecodina sumatrana Kobes, 1984, Heterocera Sumatrana 2: 30, syn. n.


Mecodina poaphiloides

Diagnosis. This is a small rather uniform species with facies typical of the genus, distinguished by an abnormally large, irregular, white-edged, dark brown patch submarginally on the forewing costa: it extends half way across towards the dorsum.

Taxonomic note
. The species was transferred to Bocula by Poole (1989), following the BMNH arrangement, but it is better placed in Mecodina as indicated by Kobes, though the valves of the male genitalia are cleft subcostally and have a setose lobe on the sacculus, and the female has the long ductus bursae sclerotised and has two small scobinate signa centrally in the corpus bursae. Martini & Thöny (1993) also noted the conspecificity of sumatrana with poaphiloides but did not make a formal synonymy.

Geographical range. Borneo, Peninsular Malaysia, Sumatra, Thailand (VK).

Habitat preference. A single female has been taken in recent surveys in lowland dipterocarp forest at 300m in the Ulu Temburong of Brunei. There is also a specimen from Beaufort, and two without precise data from G. Marapok in Sabah. The original material, taken in Sarawak by A.R. Wallace, was probably also from the lowlands. However, Martini & Thöny (1993) took the species at 800m.
