Type species

Brasiloniscus maculatus (Lemos de Castro, 1973) , by present designation.

Diagnosis

Exoantennal conglobation; pereonite 1 with dorsal v-shaped median depression on anterior portion, epimeron with schisma and dorsolateral furrow to fit antennae during conglobation; pereonites 1–3 epimera with ventral lobes slightly developed; pleon outline continuous with that of pereonite 7, neopleurae 3–5 well developed and rectangular; telson triangular, proximal portion wider than distal one; antenna partially covering eyes during conglobation, flagellum of three articles, second and third divided by slender suture, sometimes inconspicuous; uropod protopod subrectangular, exopod inserted on outer distal groove, distally; pleopod exopods with respiratory areas Atracheodillo - type.

Remarks

The characters used by Lemos de Castro (1973) to define the genus, such as cephalon with large frontal shield, pereonite 1 epimeron with well-developed dorsolateral furrow, pereonites 2 and 3 epimera with ventral lobes, and neopleurae 3–5 with distal portion not narrowed, are in fact characteristics observed at the family level, since these are also present in Pudeoniscus .

The genus Brasiloniscus gen. nov. differs from Pudeoniscus in having the pereonite 1 epimeron with lateral schisma and ventral lobe well developed, cephalon with frontal shield larger and antennal flagellum with articles subequal in length.
