Type material: Syntypes 2Ƥ 3 juv. ( SAM, #B6100, marked as " Types 5Ƥ") South West Africa, Kunene R., C 1712Aa, March 1923, R.F. Lawrence [= Namibia, Kunene, Kunene River, ca. 17°05'S, 12°10'E, 0 3.1923 (R.F. Lawrence)]; 1Ƥ ( SAM, #B6195) South West Africa, Kunene R., C 1712Aa, March 1923, R.F. Lawrence [= Namibia, Kunene, Kunene River, ca. 17°05'S, 12°10'E, 0 3.1923 (R.F.

Distribution. Africa and Arabian Peninsula.

Comments. Hyllus dotatus is widespread throughout the Afrotropical Region with several rediscriptions, e.g. Wesołowska & Russell-Smith (2000), Wesołowska & van Harten (2007) (all sub Evarcha dotata ( Peckham et Peckham, 1903)) . The body size, coloration and copulatory organs of H. dotatus varies very little. We therefore only included figures without any descriptions.
