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 note. 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.
