Distribution: Southwestern Atlantic Ocean; usually from southern Brazil (20°S) to northern Patagonia, Argentina (46°S) (Jereb & Roper, 2010).
Description
Mantle: Cylindrical and muscular ranging to about 89 mm (Table 3; Fig. 2A); ~ 3 times longer than wide.
Head: Eye diameter approximately 12% ML (Table 4). Length and width very similar to each other.
Chromatophores: Distributed throughout body, especially on dorsal region including head (around eyes); dorsal midline of mantle forming an expressive solid line in region free from fins; few chromatophores clustering in middle of fins and at arms/tentacles (Fig. 2A). Mature males do not present stripped chromatophores along ventral portion of mantle.
Fins: Rhomboid, posteriorly connected to mantle, slightly ovate and moderately long, comprising ~ 59% ML (Table 4; Fig. 2A).
Arms: Muscular, thick at base and distally tapering into slender tips; formula III>IV>II>I (~ lengths: 41 mm, 38 mm, 36 mm, 28 mm); two rows of suckers. Hectocotylus consists of ~ 40% of left ventral arm length extending to arm tip (Table 4). Left row of suckers modified into a simple peduncle whereas right row remaining as suckers. No connection between modified row and suckers, forming valley pattern throughout hectocotylus (Fig. 2E).
Tentacle: Club long and broad, ~ 37% ML (Table 4). Carpus, manus and dactylus uniformly distributed, with boundaries not very sharp, hindering their definition (especially between manus and dactylus); 4 diagonal rows of suckers along club as stated for D. pleii; 2 central rows at manus not so different in size from other suckers (Fig. 2B). Each sucker with small ring of teeth apparently at surface of sucker’s aperture. Longitudinal muscle around suckers present (Fig. 2D).
Circulatory and central nervous system: Similar to preceding species. No apparent morphological differences (Fig. 3A).
Digestive system: Pigmented tip of upper beak is long and slender (Fig.2C). Remaining structures similar to preceding species.
Male genital system: Similar to preceding species. No apparent morphological differences (Figs. 6A, 6B) except for hectocotylus above described.
Female genital system: Similar to preceding species except for nidamental glands with prominent thin tip (Fig. 5D).
