Actinotia australis sp. n.  
Delta intermediata Bremer; Holloway, 1976: 13.

Actinotia australis

15-17mm. In facies this species is very similar to intermediata Bremer and polyodon Clerck but in male genitalia is closer to the former. In both species the costal processes are long, obtusely bifid, the ventral arm of the right-hand process apically bifid again; the cucullus is triangular rather than rounded, the ventral angle with an area devoid of the fine hairs that mostly cover the interior lamina; this glabrous zone also lacks coronal setae. The distal angle of the sacculus is acutely angled in intermediata, much less so in australis. The major differences are in the aedeagus ornamentation: the apical serrate band of intermediata is lacking in australis; the subapical process is bifurcate at right angles in australis, a basally reflexed serrate spine in intermediata.

4  (slide 9049), 4   same general data as holotype, localities as listed by Holloway (1976).

Geographical range.
Borneo, Sulawesi.

Habitat preference.
The species has only been recorded for G. Kinabalu where it occurs infrequently from 1000m to 2100m.

The genus Hypericum extends through the Indo-Australian tropics so may well be the larval host of this species.
