subspecies
dunni
Evans, 1928
—original combination:
Aedes
(
Armigeres
)
albomarginata
var.
dunni
(subspecific status by
White
1975). Distribution:
Cameroon
,
Democratic Republic of the Congo
,
Nigeria (
Wilkerson
et al

)
.
Theobald (1909)
described and named
Dendromyia argenteoventralis
based on females collected in present-day
Ghana
, characterized by a moderately broad border of white scales on the anterior margin of the scutum. A form later found in
Nigeria
and described as
Aedes albomarginata
[
sic
] var.
dunni
by
Evans (1928)
was considered to be a variety of
Ae.
argenteoventralis
by
Edwards (1930)
(afforded subspecific status by
White 1975
) that differs from the typical form in having few or no white scales on the anterior margin of the scutum. As noted by
Edwards (1930
,
1941
), the male genitalia of the two forms appear to be identical. Whereas the larva and pupa of
dunni
have been described (
Evans 1938
;
Hopkins 1952
;
Edwards 1941
), these life stages of the typical form are unknown. Based on the known distributions of the two forms, with the typical form recorded from the
Central African Republic
, which is bordered by
Nigeria
to the west and
the Democratic Republic of the Congo
to the south where
dunni
is recorded, it is probable that the two forms occur in sympatry and the amount of white scaling on the anterior margin of the scutum is normal variation within a single species. Consequently,
Aedes albomarginatus
var.
dunni
Evans, 1928
is hereby formally regarded as a synonym:
dunni
Evans, 1928
, junior subjective synonym of
Aedes
(
Pseudarmigeres
)
argenteoventralis
(
Theobald, 1909
)
. This agrees with the Encyclopedia of Life, which does not list
dunni
as a species.
In addition to
dunni
(
type
locality:
Lagos
,
Nigeria
),
Dendromyia affinis
Theobald, 1909
is also a recognized synonym of
Ae.
argenteoventralis
. The
type
locality of
Dendromyia affinis
, Obuasi
,
Ashanti Region
of
Ghana
, is also the
type
locality of
Ae.
argenteoventralis
.
