Diagnosis
. The forewing length is 12.5 mm in the
holotype
female.
Gracililema proleucodes
(
Fig. 4
) is externally similar to
G. proleuca
(
Figs 1–3
) but has a somewhat wider forewing. In the female genitalia of
G. proleucodes
(
Fig. 26
), the posterior diverticulum of the corpus bursae is markedly shorter and narrower than in
G. proleuca
(
Fig. 25
), and the apophyses anteriores are longer (in proportion to the length of the ovipositor). Additionally, the ductus bursae is anteriorly dilated in
G. proleucodes
whereas it is tapered in
G. proleuca
.
Male is unknown.
Distribution
. Known only from its
type
locality in the eastern foothills of the Ruwenzori Range in western
Uganda
(
Fig. 31
).
