Ectropidia altiprimata sp. n.
14mm, 13mm. This species resembles a larger, more extensively brown-suffused E. exprimata. The contrast between basal and distal zones of the
wings is much less marked, the facies being suffused a uniform rich brown. The
palest area is the patch in the centre of the forewing margin. The forewing
postmedial is more strongly angular. The male abdomen has coremata in the same
positions as exprimata but vestigial. In the genitalia the ventral margin
of the valve costa is less sinuous, more evenly setose than in exprimata. The
ventral margin of the valve itself is straight over the distal two-thirds, with
a pair of large setae at the base of this portion and one centrally (lacking in exprimata).
