Tamba pallidisjuncta Holloway sp. n.

♂ 15mm. The moth is a slightly variegated blackish brown. The forewings have the central zone slightly paler (though crossed medially by a darker shade), bounded by a pale antemedial fascia basally and a broken pale fascia distally, formed by an oblique section of the postmedial from the costa at two‐thirds and a section of the submarginal running from the tornus approximately at right‐angles to the dorsal margin. The antemedial has a trapezoid black block basad on the costa. The genitalia are typical of the genus but with unusually long, slender distal processes to the valves, the outer one sinuous, reaching the apex of the cucullus, but the inner one, obtusely angled centrally, extending to level with the flexure of the uncus; the uncus is strongly excavated dorsally over its distal half, much as in andrica Prout. Only magniplaga Swinhoe has slender valve processes approaching those of the new species, but these are very much shorter.

Holotype ♂

SABAH: Brumas, G. arborea, 12.vii.1991 (Chey Vun Khen), BM noctuid slide 19547.

Geographical range

Borneo, Peninsular Malaysia (Barlow colln).

Habitat preference

The only Bornean specimen is from a softwood plantation with Gmelina in the lowlands (about 200m) of Sabah. The one from Peninsular Malaysia is from 600m on slopes with forest fragments amid extensive cultivation.
