DESCRIPTION

Subcylindrical carapace (lectotype: CL = 52 mm, CH = 24 mm); fusiform, tuberculate intercalated plate; inflated cardiac, hepatic and branchial regions; deep, inclined cervical groove, joined to dorsal margin and to antennal groove; deep antennal groove, strongly curved; long gastro-orbital groove, originating as a slight median inflexion of cervical groove, with two divergent branches delimiting two gastro-orbital lobes (inflated lower lobe, flat upper lobe); wide postcervical groove, strongly inclined, inflected at carapace mid-height, not joined to dorsal margin, joined to hepatic groove; shallow, short branchiocardiac groove, joined to dorsal margin, not joined to postcervical groove; concave hepatic groove, narrow, joined to cervical groove; deep inferior groove; shallow, narrow cardiac groove, straight, rising from postcervical groove, slightly inclined forward, joined to dorsal margin; carapace uniformly covered with rounded tubercles, small tubercles are between coarse tubercles; cephalic region with a row of tubercles subparallel to intercalated plate, an oblique row of tubercles in gastric region, a convex antennal row of tubercles with antennal spine; pleonal somites poorly preserved; terga with two pairs of dorsal tubercles; pleura with rounded ventral margins, covered by small tubercles; telson and uropods poorly preserved; chelate P1; short P1 propodus, almost longer than wide, covered with rounded and coarse tubercles; P1 carpus with rounded and coarse tubercles; P1 merus poorly preserved.

REMARKS

Pustulina tuberculata is close to Pustulina spinulata from Madagascar. The latter is only distinguished by its more prominent lower gastro-orbital lobe, its more inflated hepatic region and its denser tuberculation.
