Diagnosis and taxonomic note. The series of montane species from here to
mediogrisea
Warren is difficult to elucidate as they have very similar male genitalia and
variable facies, usually with white cilia at the tornus. The identities and
synonymies presented here, though based on all type material, dissected with
vesicas everted, must still be considered tentative and will probably only be
fully tested by molecular data. The feature of a peak to each component of the
transtilla noted by Holloway (1976), though indicating a subgroup within the
genus, can be distorted in preparing slides and is therefore now not considered
as helpful as originally thought. X. diluta is one of the larger species,
with a dark blackish red forewing, well separated, if somewhat obscure,
transverse fasciae and, in some specimens, an oblique darker shadow in the
centre of the medial area. It is the only species reliably distinguished on male
genitalia, as the bundle of cornuti is longer than in the other species, albeit
similarly placed laterally on the vesica. This feature serves to separate
diluta from synonymy with notodontina Felder (Poole, 1989) and
indicates conspecificity, along with facies similarity, with latera. A G.
Mulu specimen (Fig 339), noted below, has somewhat shorter and more curved
spines than the Kinabalu specimen and typical diluta, and could be an
aberrant X.
mediogrisea
Warren.
Geographical range. Peninsular Malaysia, Sumatra, Borneo.
Habitat preference. A specimen was taken at 1930m on G. Kinabalu and two
more at 1790m on G. Mulu.
