( Figs. 4 A–F)

Homaloxestis hemigastra Meyrick, 1931: 77 ; Clarke 1965: 91. Type locality: Kampala, Uganda. [NHMUK].

Material examined. Male (holotype), Uganda, Kampala, iv leg. G.L.R. Hancock [ NHMUK]. Additional specimens: 21♂, [ Uganda], Kibale National Park, Biological Field Station, 19–24 xi 2014, leg. W. Mey, gen slide. No. CIS- 7036/Park,-7072/Park, -7082/Park, -7083/Park, -7256/Park (males), wing slide CIS-7073/Park and -7084/Park, COI barcode CNBU 042 & CNBU 068; 2♀, same locality, gen slide. No. CIS-7263/Park, -7266/Park, COI barcode CBNU-073 .

Male genitalia ( Figs. 4C, D ): See also Clarke (1965, pl. Figs.1 a–b). Abdominal segment VII with a bundle of long hair-pencils; sternite VIII deeply emarginated in the middle on caudal margin, with strong, short bristles along caudal margin ( Fig. 4E ). Male genitalia characterized by valva with two processes of different length on ventral margin; cucullus deeply emarginated on ventral margin; aedeagus with more than five needle-like cornuti.

Female genitalia ( Fig. 4F ): Ostium bursae rounded, with lateral oval lamella postvaginalis and large, elongated lamella antevaginalis. Antrum cup-shaped, membranous. Ductus bursae narrowed in distal 1/4, then broadened, with indistinct conjunction with corpus bursae; ductus seminalis arising from distal margin of broadened part of bursae. Corpus bursae ovate; signum plate with two large spines anteriorly, three medium sized conic spines, and 4–5 minute conic spines.

Distribution. Uganda ( Meyrick 1931; Clarke 1964; De Prins & De Prins 2019).

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.
