Genus Cubaris Brandt, 1833

Cubaris Brandt, 1833: 489 .

TYPE SPECIES. — Cubaris murina Brandt, 1833 , by subsequent designation ( Barnard 1932).

DIAGNOSIS. — After Schmalfuss & Ferrara (1983) and Taiti et al. (1998): animals with complete endoantennal conglobation; roller habitus (sensu Schmalfuss 1984); dorsal surface smooth or granulated covered with short tricorn, semi-circular or elongated scale-setae; pereonites 1-7 with one line of short noduli laterales inserted at same line and near posterior margins; cephalon with subrectangular frontal shield delimited from vertex by frontal line, lateral lobes well developed, suprantennal line absent; pereonite 1 epimera with anterior corners developed frontwards to fit cephalon during conglobation, posterior corner concave, short triangular lobe on ventral; pereonite 2 epimera bearing rectangular lobe direted outwards (sometimes reduced); pereonites 1-7 epimera directed backwards; pleon outline continuous with that of pereonite 7; pleonites 3-5 epimera subrectangular and well-developed; telson hour-glass shaped, distal margin slightly convex; mandibles with molar penicil semi-dichotomized, left mandible with 2+1 penicils, right mandible with 1+1 penicils; maxillula of 4+5-6 teeth apically simple; maxilla bilobate; maxilliped endite bearing two long setae on distal margin plus medial seta; pereopod 1 carpus with longitudinal antennal grooming brush; uropod protopod rectangular, flattened, filling gap between pleonite 5 and telson, medial margin concave bearing small exopod, endopod longer than exopod; pleopod exopods with monospiracular pleopodal lungs (see also Collinge 1916; Taiti & Ferrara 1987; Lewis 1998; Lillemets & Wilson 2002).

REMARKS

Brandt (1833) erected Cubaris to allocate C. brunnea (synonym of C. murina ) from Guyana, C. cinerea and C. murina from Brazil, C. flavescens (synonym of Venezillo f.), C. limbata (synonym of Bethalus limbatus ), and C. nigricans (synonym of Venezillo n.) from South Africa.To date, the genus comprises about 60 species with a circumtropical distribution ( Schmalfuss 2003). Several species have been mistakenly assigned to the genus which still needs a comprehensive revision (see Schmalfuss 2003). The present diagnosis is tentative, aiming to assist future studies on the genus.
