Boarmacaria Gen.
n.
Type species: tenuilinea Warren.
The type species was originally in a macariine genus but lacks the
features of that tribe. The male fovea is more typical of the boarmiines. The
third abdominal sternite of the male has a strong setal comb, and the antennae
of that sex are fasciculate. The wing shape is reminiscent of that of some
macariines, with the hind wing margin slightly excavated in the spaces,
particularly that between M1 and M3. The wings are heavily marked with blackish
brown on a pale grey ground, with the darkest marking being a broad, irregular
submarginal band that arches over the posterior half of the forewing and the
anterior half of the hindwing margins to isolate a narrow zone of paler colour.
The male genitalia have a triangular, apically truncate or bifid uncus,
a moderate to strong gnathus. The valves have basal coremata and are
characterised in the type species by bilateral asymmetry in the form of
unequally developed costal processes that have dorsal and ventral components: in
the new species there is symmetry and the ventral process is more definitely
associated with the sacculus. The aedeagi of the two species also differ, that
of the type species being elongate with a tapering apical sclerotisation, that
of the new species shorter with a vesica cornutus.
The female genitalia also differ, that of the type species having a
broad, irregularly conical, sclerotised ostium, a short ductus, a longer than
broad bursa without a neck or signum, but with the basal part lightly
sclerotised.
