Pelagodes cochlearis sp. n.  


Pelagodes cochlearis ♂
(holotype, Sumatra)


♂♂ 19-20mm, 21mm. This is the largest species noted in Borneo; the facies is typical of the genus. Again, diagnostic features are in the male abdomen: the processes of the eighth segment are short broad, spoon-like; the process from the valve costa is digitate, blunt, slightly flexed, well subapical: the ventral margin of the valve is stepped.

The genitalia of a putative Bornean female from the same locality as the male are illustrated.

Holotype ♂ Lebong Tandai, W. SUMATRA, 6.xii.1921 (C.J. Brooks coll.) No 4179, BM geometrid slide 4077.

Geographical range. Sumatra, Borneo (slides 8466 (♂), 10712 (♀)).

Habitat preference. Two Bornean specimens are from mixed dipterocarp forest at 150m (Mulu survey), and a third from Bidi, also in the lowlands of Sarawak.
