Type species. Stephenseniellus palliolatipes sp. nov., here designated.
Species included. Stephenseniellus palliolatipes sp. nov., S. serraticornis sp. nov.
Etymology. The genus is named in honour of renowned Danish carcinologist Dr K. Stephensen.
Diagnosis. Body broadly ovate, greatest width 50% length or more. Protruding frontal margin of head evenly convex, dorsally upcurving anteriorly, without lateral corners but indented at antennular insertion, anterior rim dorsoventrally thin, pointed in lateral view. Antennula with 5 articles. Pereopod I carpus triangular. Pereonites 5–7 lateral margins angular, not projecting over coxae, with several robust setae on margin. Coxa pereopod I with rounded lateral projection; coxae pereopods V–VII visible in dorsal view, angular and projecting (weakly developed in male of S. palliolatipes ), without lateral denticles, with single apical robust seta. Pleotelson proximal margin of subequal length to lateral margin, with denticles mainly on mid lateral curvature.
Remarks. Stephenseniellus differs from Austronanus and from Xigonus in having the front margin of the head evenly convex without an angled midpoint, laterally projecting coxae 1 and 5–7 (but note similar coxae V–VII in A. dentatus ), and a pentagonal pleotelson with denticles on the midlateral bulges only.
