TYPE SPECIES . — Cubaris murina Brandt, 1833 , by subsequent designation ( Barnard 1932 ). FIG . 23. — Photographs of Ctenorillo ferrarai Campos-Filho, Araujo & Taiti, 2014 , male specimen from Serra Leste cave system: A , lateral habitus; B , dorsal view of the pereonite 7, pleon, telson, and uropods. Scale bars: 1 mm. 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.
