Remarks . Afroleius inae sp. nov. is recognized by the long lamellae, rostral and lamellar setae of similar length and unique dorsal sculpturing, being reticulate with fine sculpture within the cavities. The stalk of the bothridial seta is slightly thicker than in the species described above. The absence of the genal incision and the genal tooth being fused to the rostral margin is rare in Ceratozetoidea. This character state is expressed in Nuhivabates Niemi & Behan-Pelletier, 2003 (Mycobatidae) as well as in some Melanozetes species (Ceratozetidae) (Behan-Pelletier 1986; Niemi & Behan-Pelletier 2003). Afroleius inae sp. nov. is distributed widely in South Africa, occurring along the east coast region, grasslands of the interior and savanna of the northern regions. Etymology . This species is named for my sister, Ina Engelbrecht, in recognition of her encouragement and provision of material. : Published as part of Coetzee, Louise, 2014, Afroleius floridus (Mahunka, 1985) comb. nov. and three new Afroleius Mahunka, 1984 species (Acari: Oribatida: Mycobatidae) from South Africa, pp. 553-573 in Zootaxa 3889 (4) on pages 564-565, DOI: 10.11646/zootaxa.3889.4.4, http://zenodo.org/record/228987 : {"references": ["Mucina, L. & Rutherford, M.
