Xenochroa fulvescens
Diagnosis and taxonomic note. The forewing is obscurely marked, variegated
brown when worn, but with more distinctly transverse, diffuse vinous bands when
fresh; the holotype of obliquifascia is worn, with rather oblique darker
shading remaining. The hindwings are pale to medium rufous brown. The male
genitalia are generally as in the preceding species, distinguished by the
aedeagus vesica where the cornuti form an extensive row relatively dorsally,
variable in size, with some smaller ones dispersed slightly ventrally from a row
of longer ones. The holotypes of all three full species brought into synonymy
have genitalia of this form. The specimens attributed to rubiginosa by
Kobes (1997) appear to be referable to X.
plesiogramma
Prout. The Kei “syntypes” of fulvescens referred to by Kobes
(1997) have not been located but are no longer associated with the holotype in
the series in BMNH. It is evident from the original description that their
association with fulvescens was tentative.
Geographical range. Sundaland, ?Kei Is.
Habitat preference. The species is rare in Borneo but possibly more frequent
in the lower montane zone. In recent surveys singletons have been taken at: 350m
in lowland forest of the Ulu Temburong, Brunei; from 1000m on G. Mulu; from
1200m on G. Kinabalu; from 1200m in stunted hill forest on Bukit Monkobo, Sabah.
The holotype of obliquifascia is from Mt. Matang (no altitude) in
Sarawak.
