Nygmia javanoides sp. n.  

Nygmia javanoides (holotype)

28-29mm. In facies this species is very similar to javana and epirotica. One possible difference that requires confirmation in additional material is on the forewing underside where the discal spot is faint but visible (not so in epirotica, sometimes so in javana); the brown shading is also relatively strong. The male gentialia are diagnostic; the upper arm of the valve is narrower, its distal margin more oblique; the aedeagus vesica is longer, more tapering beyond the basal bulge, the scobination extending almost to the apex.

Holotype . BRUNEI: 75m, Labi, Feb 82 (Lt. Col. M.G. Allen) BM lymantriid slide 2633.

Paratype . SARAWAK: Gunung Mulu Nat. Park, R.G.S. Exped. 1977-8 (J.D. Holloway et al.) Site 23, April, W. Melinau Gorge, 250m, 430558, FEG 4, limestone forest. BM lymantriid slide 1776.

Geographical range. Borneo, Sumatra (slide 1790; Schintlmeister, 1994: fig 145-1).

Habitat preference. The species is uncommon in lowland forest. Two further males (undissected, therefore not included as paratypes) have been taken in Brunei at 200m at Rampayoh and at 300m in the Ulu Temburong.
