Notes: Oldroyd lists the
holotype
and
three female
paratypes
stating that they are in IPNC (
Institut des Parcs Nationaux
(du
Congo
),
Bruxelles
).
Oldroyd’s
first listed
paratype
does not have ‘
Same
data as holotype’—instead of 3282 it is numbered 3298.
His
second
paratype
‘483. 1/a/1.
1^5.v.1950
’ was not sent to me for study. Full label data for Oldroyd’s third
paratype
, gender not stated, are provided above. This is also a female. Types seen by me are all in MRAC, not IPNC
.
Oldroyd (1970: 248, fig. 26) compared the genitalia to
erythropus
, but see discussion above.
Distribution and biology: Known only from the
type
series from the
Democratic Republic of Congo
, collected in November, April and May.
