Remarks.
This species was described as a species of
Homaloxestis
from
Kampala
,
Uganda
, based on a single male. However, the species does definitely belong to
Furcalis
Park, 2018
, by having the distinct diagnostic characters in the venation and the male genital character of this genus, and thus, is transferred here to this genus as
F. hemigastra
(
Meyrick, 1931
)
,
comb. nov.
The female is reported and illustrated for the first time.
