Microcerberus brasiliensis Albuquerque, 1978: 213 , figs. 17–20. — Albuquerque, 1998: 625.

Coxicerberus brasiliensis — Wägele et al., 1995: 743.

Type material. Holotype: male, 0.83 mm, MNRJ 6247 . Paratypes: 1 male, 2 females; 1 male, 2 females, USU .

Type locality. Barra da Tijuca Beach , coarse sand ,

100 cm depth, RJ, Brazil.

Geographic distribution. Brazil: Vermelha, Barra da

Tijuca, Recreio dos Bandeirantes and Imbuí Beaches

( RJ) ( Albuquerque, 1978; Albuquerque and Genofre, 1999).

Habitat. Interstitial, littoral in intertidal zone, on beaches with medium to coarse size sand ( Albuquerque, 1998).

Current systematic position. Robustura brasiliensis

( Albuquerque, 1978).

Remarks. Wägele et al. (1995) listed Robustura Gnanamuthu, 1954 as a junior subjective synonym of Coxicerberus Wägele, Voelz and McArthur, 1995 but that is incorrect, and the former is the senior subjective synonym following Article 23 of the principle of priority ( ICZN, 1999). So, species previously included in Coxicerberus are now in Robustura ( Boyko et al., 2023) . Paratypes deposited at the Department of Animal Biology of Santa Úrsula University ( USU) lack voucher numbers.
