Aedia Hübner
Type species: leucomelas Linnaeus sensu Hübner = funesta Esper, W. Germany.
Synonyms: Anophia Guenée (type species leucomelas Linnaeus, Europe); Catephiona Hampson (type species lichenea Hampson) syn. n.; Dysedia Rogenhofer (type species zibellina Felder & Rogenhofer = intrahens Walker) syn. n.; Eucatephia Hampson (type species dinawa Bethune‑Baker, New Guinea) syn. n.; Herchunda Swinhoe (type species hirtissima Walker) syn. n.; Idicara Walker (type species olivacea Walker) syn. n.; Premusia Walker (type species intrahens Walker) syn. n.
The facies is
diverse, but the forewings are relatively narrow, and frequently are divided by
an irregularly sinuous and sometimes double postmedial into a marginal third,
sometimes relatively paler, and a basal two thirds, often with a darker zone in
the medial area bounded by the postmedial distad, and by a strongly sinuous
anterior border that runs anteriorly along the antemedial from the dorsum, then
curves round distad to circumnavigate the discal area with the often obscure
reniform and orbicular stigmata to meet the costa just basal to the postmedial.
This is probably most clearly seen in hirtissima Walker, and the feature is shared with Ecpatia Turner (see below). The hindwing in most species is
white to pale yellow with a broad brown or blackish brown border. This border
may be broken at the margin by paler sections, e.g. at the apex and tornus in
the leucomelas group.
The labial palps
are upturned, mainly through the second segment, with the third, straight and
slightly shorter, extending to just above the top of the head or back over it (intrahens Walker). Males in several species have extensive
secondary sexual features such as hair tufts on the hindwings and legs (e.g. lobata
Prout) or generally over the hindwings (hirtissima). The male antennae
are filiform, varying from smooth to fasciculate.
The male abdomen
has the eighth segment of the framed corematous type, but is diverse in
structure. The sternite has a single corema when such is present (e.g. hirtissima),
but there may be a pair flanking the narrow anterior part of the tergite (e.g. intrahens).
The genitalia have characteristic elongate valves, usually tapering at the apex
and with a row of coronal setae set interiorly over the distal part of the
ventral margin. The valves do not extend beyond the saccus but usually have
massive coremata exteriorly over the basal part. There is a conspicuous radula‑like
structure within the anellus overlying the aedeagus dorsally, and the aedeagus
itself terminates in a curved spine.
The female
genitalia have the ostium just anterior to the ventral gap in the ring of the
eighth segment. The ductus bursae is usually sclerotised basally but may be
corrugated distally, and there may be sclerotisation and corrugation at the
base of the corpus bursae. The corpus bursae is variable in shape but lacks a
signum.
