Xerodes ypsaria Guenée, 1857, Hist. nat. lnsectes, Spec.
Gen. Lep., 9: 291.
Ennomos testacearia Moore,
1867, Proc. zool. Soc. Lond., 1867: 623.
Xerodes ypsaria Guenée; Holloway, 1976: 81.
Diagnosis: The forewings are a dull, medium to light, rufous brown-grey. The
postmedials are indistinct rows of black dots on the veins, that on the forewing
gently sigmoid. The discal spots are also small, black. Many specimens have
straight, rather diffuse oblique black medials traversing the wings just distal
to the discal spots. Pale yellow patches often occur between the forewing medial
and postmedial on either side of CuA2.
Taxonomic notes. X. cinerosa Warren (Adonara, Lesser Sundas) and X. albisparsa Warren
(New Guinea) differ only slightly in male genitalia and facies from ypsaria and
may merely represent races thereof. The genitalic differences are in the size
and shape of the vesica cornutus: twice as long in albisparsa; shorter,
more ovate in cinerosa.
Geographical range. N.E. Himalaya, Peninsular Malaysia, Borneo, Sulawesi.
Habitat preference. The species is infrequent, mostly taken in lower
montane forest (900m on G. Api and 1000m on G. Mulu) during the Mulu survey, but
ranging from 1200m to 1930m on G. Kinabalu.
