Redescription
MEASUREMENTS. Maximum body length: 8 mm.
BODY. Habitus in lateral view as in Fig. 3A View Fig. 3 . Material depigmented due to long preservation in ethanol 70% ( Fig. 7B View Fig. 7 ). Dorsum ( Fig. 3A View Fig. 3 ) with well-developed ribs and tubercles on median and paramedian areas of pereonites; noduli laterales short, inserted far from lateral margin and in each pereonite progressively near to posterior margin.
CEPHALON ( Fig. 3B–C View Fig. 3 ). Lateral lobes slightly bent upwards, frontal shield with lateral sides concave; eyes consisting of 15 ommatidia.
PEREON. Pereonite 1 epimeron with strong dorsolateral furrow with posterior margin elongated, ventral lobe of schisma narrow, directed backwards, dorsal lobe subrectangular slightly directed outwards, surpassing lateral margin of inner lobe. Pereonites 2 and 3 with ventral lobes rounded, more conspicuous on pereonite 2 ( Fig. 3A, D View Fig. 3 ).
PLEON ( Fig. 3E View Fig. 3 ). Neopleura 5 not surpassing distal margin of uropod protopod; telson with shallow dorsal depression, lateral sides concave.
ANTENNULA ( Fig. 3F View Fig. 3 ). Proximal and distal articles similar in length, distal article with subapical aesthetascs.
ANTENNA ( Fig. 3G–H View Fig. 3 ). Fifth article of peduncle longer than flagellum. Flagellum with third article slightly longer than second.
MOUTH. Buccal pieces (not drawn) as in B. maculatus .
PEREOPODS 1–7 ( Fig. 4A–C View Fig. 4 ). With sparse setae on sternal margin, carpus 1 with distal seta serrate at apex, longitudinal antennal grooming brush; dactylus with inner claw not surpassing outer claw, dactylar and ungual setae simple.
FEMALE PLEOPOD 1–5 EXOPODS. As in Fig. 4D–H View Fig. 4 . Uropod ( Fig. 3E View Fig. 3 ) endopod about twice as long as exopod.
Remarks
Lemos de Castro (1973) provided the description of this species based on females. Even though the respiratory area can be seen, it is not possible to compare the male characters. Also, as mentioned by Lemos de Castro (1973), B. verrucosus gen. et comb. nov. differs from B. maculatus gen. et comb. nov. by the distinct dorsal tuberculation, the shape of telson with distal portion narrower, the shape of schisma on pereonite 1, and the shape of ventral lobes on pereonites 1 and 2. All these characteristics were confirmed here, however male characters remain unknown.
