Description.
Antennae bipectinate in male and filiform in female. Wings brown, densely suffused with brown spots; apex of forewing pointed; outer margin of hindwing slightly protruding at vein M3. Veins R1 to R5 longstalked in front of the areole on forewing. Antemedial line indistinct with black spots on forewing; medial line absent; postmedial line curved, composed of black spots on both wings. Discal spot on forewing black and whitecentred on hindwing.
Male genitalia
(
Figs 25
, 35). Uncus thick. A long spinose process from tegumen present, with a spur at base. Valva broad but thin terminally, and densely setose on ventral margin; costa strongly inflated, with hillock-shaped process at middle (in fig. 25 the valva folded back artificially and thus not in correct position). Aedeagus thin, with indistinct sclerotized bands on vesica.
Female genitalia
(
Fig. 44
). Papillae anales pointed. Apophyses anteriores about 1/2 as long as of apophyses posteriores in length. Lamella antevaginalis sclerotized and irregular; lamella postvaginalis oval and strongly sclerotized; Ductus bursae nearly as long as corpus bursae, sclerotized weakly on posterior part. Corpus bursae rounded and lacking signum.

Diagnosis
. Compared to true members of
Synegiodes
, “
Synegiodes
”
brunnearia
is characterized by differences in wing pattern and genitalia. The ground color is pale greyish brown, rather uniform; the postmedial lines are composed of small black dots only; antemedial lines are similar. The medial lines broad and continuous, but indistinct, shadow-like. The discal spot on the forewing is a tiny black dot, almost invisible and situated distinctly outside the medial shade, not white-centred as in typical
Synegiodes
. However, a white-centred discal spot is found in the hindwing of
brunnearia
. In the male genitalia,
brunnearia
possesses a pair of long teguminal processes. Compared with the species of
Synegiodes
, they have a different shape and are located more posteriorly. The shape of the valva, very uniform in
Synegiodes
, is also completely different. In the female genitalia, the colliculum is absent, but well developed in all
Synegiodes
.
The corpus bursae is oval, without a signum and abruptly constricted towards the narrow ductus bursae but it is drop-shaped and narrowing gradually to a wide ductus bursae (in some species the ductus bursae is as wide as the corpus bursae), the ductus is extended to a curved diverticulum near the colliculum and the signum is present and of a very distinctive shape in
Synegiodes
.

Remarks.
The species
brunnearia
Leech
was originally described in the genus
Ephyra
Duponchel, 1829, which is treated as a synonym of
Cyclophora
Hübner, 1822
at present (
Parsons
et al
. 1999
). Prout (1913: 46) placed it in
Anisephyra
Warren, with a statement that it is not a typical species of
Anisephyra
. Later Prout (1935: 27) transferred
brunnearia
to
Synegiodes
, though he noted that
brunnearia
is divergent in a number of characters from the other species of
Synegiodes
. Again some years later Prout (1938: 152) stated that
brunnearia
is somewhat aberrant from
Synegiodes
, his earlier treatment as a member of
Anisephyra
was probably preferable or that
brunnearia
may require a separate genus. Since then, its position in
Synegiodes
has not changed.
Anisephyra
was a valid generic name in
Fletcher (1979)
, while
Parsons
et al
. (1999)
treated it as a synonym of the predominantly African genus
Palaeaspilates
Warren
, by transferring its
type
species
rufaria
to the latter, without giving any reason, and leaving
ocularia
Fabricius, the only other species of
Anisephyra
, in “
Anisephyra
”. Prout (1938: 152) considered
ocularia
to have very much in common with the African
Palaeaspilates
, so probably it should also be transferred to this genus.
It is obvious that
brunnearia
does not belong to
Synegiodes
and it is also very different from
rufaria
, the
type
species of
Anisephyra
(pl. 16e in Prout, 1938) externally, for example, in the different forewing postmedial line and hindwing discal spot.
Summarized,
“
Synegiodes
”
brunnearia
probably requires a new genus, but a detailed study of related genera should be done before, and this is beyond the scope of the present paper.
