Eupithecia
delozona Prout
Eupithecia
delozona Prout, 1926, Sarawak Mus. J., 3:184.
Diagnosis. The broad purplish medial zone of the forewing with pale yellow distally
and pale brown basally is diagnostic. The hindwings are also pale brown, grading
pale golden yellow distally.
Taxonomic notes. This is an unusually colourful species for the genus and appears to be
closely related to the N.E. Himalayan E. biviridata Warren, though with a
somewhat straighter forewing antemedial and a stronger yellow margin to the
hindwing. The male genitalia of biviridata (Fig 394; the abdomen of delozona
is missing) are consistent with placement in Eupithecia, but the
octavals are well separated. The apodemes of the second tergite are short.
Figures 313 and 316 show the 
genitalia of E. delozona Prout and Celaenaclystis
telygeta Prout, both from specimens taken at Kundusan on the south of G.
Kinabalu. Those of E. delozona confirm
close relationships to the Himalayan E. biviridata Warren, with only minor
differences evident in the curvature of the valve margin, the apex being more
rounded in delozona. Those of telygeta are much less strongly modified than in
the type species, C. celaenacris
Prout, but have a comparable, broad, square saccus. There are homologies
also in the structure of the uncus/tegumen complex that support the congeneric
status of the two species.
Geographical range. Borneo.
Habitat preference. The species was known only from the holotype, from
about 2000m on G. Murud in Sarawak. A second specimen from 1200m at Kundasang on
the slopes of G. Kinabalu has been seen in colln Herbulot.
