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 2.432.74% distant from D. ethani sp. n. Adults, male genitalia and distribution maps of all three species are illustrated.

A new genus of Afrotropical Lasiocampini: Revaya gen. n. (Lepidoptera, Lasiocampidae, Lasiocampinae).

A new genus Revaya gen. n. with Revaya yahya sp. n. (type-species) and Revaya edita sp. n. are described. A detailed diagnosis for the new genus is provided and compared with three closely related genera: Catalebeda Aurivillius, 1902; Ptyssophlebia Berio, 1937; and Oplometa, Aurivillius 1894. Male genitalia of Oplometa cassandra (Druce, 1887) and female genitalia of Ptyssophlebia discocellularis (Strand, 1912) are illustrated for the first time. Catalebeda producta, P. discocellularis and O. cassandra are recorded for the first time in the Democratic Republic of the Congo.

Phragmacossia bozanoia new species from southern Greece with some notes on Phragmataecia and Phragmacossia (Lepidoptera, Cossidae, Zeuzerinae).

The taxonomic relationship between the genera Phragmataecia Newman, 1850 and Phragmacossia Schawerda, 1924 is considered. Diagnostic characters and distribution of the species Phragmataecia castaneae (Hbner, 1790), Phragmataecia albida (Erschoff, 1874), Phragmacossia ariana (Grum-Grshimailo, 1899), Phragmacossia territa (Staudinger, 1879), and Phragmacossia minos Reisser, 1963 are studied in detail. A new species, Phragmacossia bozanoi sp. n., is described from the Peloponnese Peninsula and the South Greek mainland.
