Description of two new species of Dinometa from East Africa with remarks on D. maputuana (Lepidoptera, Lasiocampidae, Lasiocampinae)

The genus Dinometa Aurivillius, 1927 (type species Gastroplakaeis maputuana Wichgraf, 1906) is reviewed, with two new species described: Dinometa ethani sp. n. from Tanzania and Dinometa abigailae sp. n. from kenya and Tanzania. All Dinometa species showed no significant differences in male genitalia, but D. ethani sp. n. and D. abigailae sp. n. are allopatric with D. maputuana. D. abigailae sp. n. has specific reddish spots on hindwings that distinguishes it from closely distributed D. ethani sp. n. Two D. maputuana specimens collected at the same night and locality in the republic of South Africa have an intraspecific variation of 1.52% in cytochrome c oxidase subunit I, while all barcoded D. maputuana are 2.43–2.74% distant from D. ethani sp. n. Adults, male genitalia and distribution maps of all three species are illustrated.
