Thubdora bilobella Park, 2018

( Figs. 6A–E )

Thubdora bilobella Park, 2018: 1089 ; Park et al., 2020: 471 . TL: Cameroon.

Material examined. 1♂, Equatorial Guinea, Island of Bioko (former Fernando Póo), Gran Caldera Volcanica de Luba u Ose, outer NNE slope about 4 km SSW Ruiché, 5 km S of Luba, higher altitude primary rain forest, 1200 m, 3°22’30” N 8°32’30” E, 18 viii 1994, at light, leg. T . Karisch, gen. slide no. 3824/Karisch; 1♂, same locality, 20.viii.1994, in coll. MNVD, coll. Karisch ( SDEI) .

Remarks. This species was originally described from Cameroon ( Park, 2018) and also reported from Uganda by Park et al. (2020). This species can be distinguished from its allies by the shape of the uncus, the valva, and the aedeagus in the male genitalia. Little differences from the type specimen of the species ( Fig. 5E ) are found in the male genitalia, with the uncus less directed outwardly and the triangular caudal plate of juxta smaller, However, those differences are considered to be infraspecific variation. A further study is needed.

Male genitalia ( Figs. 6C, D ): See also Park (2018, Figs. 15, 15a).

Distribution. Equatorial Guinea (new record; Isl. Bioko). The species was originally described from Cameroon ( Park, 2018) and was also reported from Uganda ( Park et al. 2020).
