Eupithecia confusata Walker,
1866, List Specimens lepid. Insects Colln Br. Mus., 35: 1676.
Eupithecia subtristigera Walker,
1866, Ibid., 35: 1679, syn. n.
Diagnosis and taxonomic notes. This and the next species are easily confused and are
perhaps only reliably separated by dissection of the male genitalia, where
confusata has much larger cornuti in the aedeagus vesica as in the
Australasian taxa mentioned in the introduction to the complex. This
species is somewhat darker, more strongly marked, with the hindwing
postmedial straighter over the posterior two-thirds, less biangular, and
more clearly defined by a paler band distad. The female has a broader,
shorter, more scobinate and sclerotised ductus that broadens slightly
towards the ostium. The specimen identified as confusata by
Holloway (1976) is a damaged female with genitalia (slide 9091) not
entirely consistent with the above diagnosis. It may in fact be imparatalis.
Geographical range. Borneo, Singapore, Peninsular Malaysia, ?India.
Habitat preference. Specimens taken in recent surveys are all singletons
from various montane forests: 1618m on Bukit Retak; 900m on G. Api; 1000m
on G. Mulu. The original material is likely to have been from the
lowlands.
