Triaina View in CoL gen. nov.
Diagnosis. Janirellidae with flattened body, body margins parallel. Pereonites lateral margins squarely truncate. Head broader than long, with distinctive pseudorostrum, front margin straight to slightly convex. Pleotelson irregularly rectangular; posterior projection short, broadly rounded or truncate, barely projecting beyond distolateral corners of pleotelson. Head, body and pleotelson without dorsal or lateral spines or robust setae. Uropods tiny.
Type species. Triaina isodonte sp. nov. Here designated.
Included species. Triaina isodonte sp. nov., T. makridonte sp. nov.
Etymology. The genus name is the Greek ρɩαɩνα ( triaina ) meaning trident, Poseidon’s three-pronged fish spear, alluding to the shape of the pseudorostrum.
Remarks. Triaina differs from Janirella and Dactylostylis in possessing a distinctive pseudorostrum, in the flattened, parallel-sided body, in lacking lateral and/or dorsal spines or robust setae on pereon and pleon; and from Dactylostylis in the tiny uropods.
