Four new Afrotropical Hypotrabala from moist broadleaf forests and the first description of the female of H. obscura (Lepidoptera, Lasiocampidae, Lasiocampinae, Selenepherini)

"Four new species in the genus Hypotrabala Holland, 1893 are described: 1) Hypotrabala leopoldi sp. n. from the Democratic Republic of the Congo (DRC); 2) Hypotrabala benjamini sp. n. from DRC; 3) Hypotrabala carlottae sp. n. from Côte d’Ivoire and Ghana; and 4) Hypotrabala bettinae sp. n. from Nigeria. They are somewhat reminiscent of the dark colored Hypotrabala obscura Takano & László, 2024 known from the type series of four males originating from Gabon. The female of H. obscura and its genitalia are described for the first time; the species is recorded for the first time for Cameroon. Adults of both sexes, their genitalia, and map with collecting localities are illustrated.
