Genus Gamboa Bamber, 2012 View in CoL

Diagnosis (modified after Bamber 2012). Body glabrous, about ten times as long as wide. Eyelobes fused to carapace, with visual elements. Labrum setulose. Right mandible pars incisiva with crenulate distal margin and bilobed inner-distal corner; pars molaris stout, armed with teeth. Maxillule endite bent almost at a right-angle; maxilliped endites with setae but no distal tubercles. Cheliped with one single ventral seta on merus, carpus not produced. Coxae of all pereopods with one seta, without apophysis. Pereopods 4–6 without prickly tubercles, with distal spines on merus, carpus and propodus. Pleopods absent in female. Exopod of uropod shorter than endopod. Remarks. Gamboa , described from Cape Verde Islands, Macaronesia, is the only genus of the family Nototanaidae with females lacking pleopods, a character which has been attributed to an interstitial mode of life (Bamber 2012). Other character reductions, such as the presence of three spines on pereopods 4–6 carpus (four in other nototanaids), and the scarcity of setae on pereopods 1–3, have been seen as apomorphic characters related to the small size (Bird 2012), as they are only present on the smallest representatives within the Nototanaidae (i.e., Stachyops Bird, 2012 and Gamboa ).

This is the first record of this monotypic genus since its description, and the diagnosis is herein modified to accommodate the newly described species (see remarks on the species below).
