An annotated checklist of Brazilian sea spiders (Arthropoda: Pycnogonida) Author Lucena, Rudá Amorim Author Christoffersen, Martin Lindsey text Zootaxa 2018 2018-01-10 4370 2 101 122 journal article 31042 10.11646/zootaxa.4370.2.1 5dac3069-b21b-4198-b011-4ec91199dbad 1175-5326 1143857 BAC55638-7B2C-4E08-AE5A-0AF0998ECE6D Rhynchothorax sp. Rhynchothorax mediterraneus —Zilberberg, 1963: 21–25, figs 1 –4 ( Brazil : Ilha de Trindade , 50–70 m ) (non Costa, 1861). Holotype: Unknown. Type locality: Unknown. Remarks: Part of the material analyzed by Zilberberg (1963) was re-analyzed by Child (1988) , who concluded that some specimens identified as R. mediterraneus belong to R. monnioti ( Stock 1992: 135 ) . However Child’s record is doubtful ( Bamber & Costa 2009 ) and is not included here. We did not have access to the material of Zilberberg (1963) and are unable to confirm his identification, so we prefer to maintain this species unnamed.
