Tyana marina Warren

Tyana marina Warren, 1916, Novit. zool., 23: 215.

Tyana marina Warren; Holloway, 1976: 22.

Diagnosis

The species is very variable but always has apple-green forewings and white hindwings. The latter are reduced in the male and invested with a hair-pencil of pale cream-coloured hairs along the underside of the dorsum. The forewing apex and tornus are tinged reddish, but the fringes over the rest of the margin are yellow. Forewing markings are variable as illustrated, sometimes with a discal blotch of pale yellow, ringed with red or extensively or completely suffused with the same, this sometimes extending to the tornus; other specimens may just have red at the tornus. The patagia and tegulae may be similarly coloured.

Taxonomic notes

The male genitalia of marina and the four species recorded by Kobes (1997) from Sumatra appear identical except for minor differences in the cornuti in the aedeagus vesica (constant in Bornean males dissected). It is difficult therefore to ascertain the validity and relationships of all these taxa.

Geographical range

Borneo.

Habitat preference

This is a common montane species, found from 900m to 2600m, perhaps most abundant around 1930m.
