DESCRIPTION

Subcylindrical carapace (CL = c. 46 mm with incomplete cephalic region, CH = 24 mm); inflated cardiac, hepatic and branchial regions; wide, deep cervical groove, straight, narrowing ventrally, joined to dorsal margin and to antennal groove; wide gastro-orbital groove; very wide, deep postcervical groove, straight, dorsally strongly inclined, narrowing under its inflexion, not joined to dorsal margin, joined to hepatic groove; wide, concave hepatic groove, joined to cervical groove; deep inferior groove, joined to hepatic groove; wide, straight cardiac groove, strongly inclined forward, rising from postcervical groove, probably joined to dorsal margin; carapace ornamented with coarse, widely spaced, rounded tubercles.

DISCUSSION

The holotype is probably lost and the present description is based on the figure proposed by Van Straelen (1936). Its low resolution does not allow to see the branchiocardiac groove. If this groove is present, it is too shallow and narrow to be distinguished.

Initially assigned to Eryma by Van Straelen (1936), the species was reassigned to Phlyctisoma sp. (now Pustulina sp. ) by Förster (1966) based on its typical groove pattern (long gastroorbital groove, strongly inflected postcervical groove joined to hepatic groove, concave hepatic groove, cardiac groove). Our examination of the original figure leads us to confirm Förster’s placement.Moreover, the ornamentation and the welldeveloped cardiac groove are substantial enough to maintain the validity of the species described by Van Straelen (1936). Consequently, this situation leads to a case of secondary homonymy.To solve this problem and according to ICZN (1999: articles 53.3, 57.3), we propose herein the replacement name Pustulina victori nom. nov. pro P. tuberculata ( Van Straelen, 1936) non P. tuberculata ( Bell, 1863) .
