Brachyuran crabs (Crustacea, Decapoda) from the remote oceanic Archipelago Trindade and Martin Vaz, South Atlantic Ocean Author In, First Published text Zootaxa 2022 2022-06-02 5146 1 129 journal article 10.11646/zootaxa.5146.1.1 1175­5334 52C3E5E3-80B6-49DB-BC9C-194560D491F7 Genus Johngarthia Türkay, 1970 Type species. Gecarcinus planatus Stimpson, 1860 [ Type locality: Todos Santos , near Cape St. Lucas , Lower California ] Remarks. Tavares (1989 ; 1991) found no adult characters to support the monophyly of Johngarthia . The existing scattered data on larval morphology apparently do not support the monophyly of Johngarthia as well ( Colavite et al. 2021 ). Further evaluation is required.
