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 View Table 3 ; Fig. 2A View Figure 2 ); ~ 3 times longer than wide.

Head: Eye diameter approximately 12% ML ( Table 4 View Table4 ). 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 View Figure 2 ). 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 View Table4 ; Fig. 2A View Figure 2 ).

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 View Table4 ). 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 View Figure 2 ).

Tentacle: Club long and broad, ~ 37% ML ( Table 4 View Table4 ). 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 View Figure 2 ). Each sucker with small ring of teeth apparently at surface of sucker’s aperture. Longitudinal muscle around suckers present ( Fig. 2D View Figure 2 ).

Circulatory and central nervous system: Similar to preceding species. No apparent morphological differences ( Fig. 3A View Figure 3 ).

Digestive system: Pigmented tip of upper beak is long and slender ( Fig.2C View Figure 2 ). Remaining structures similar to preceding species.

Male genital system: Similar to preceding species. No apparent morphological differences ( Figs. 6A, 6B View Figure 6 ) except for hectocotylus above described.

Female genital system: Similar to preceding species except for nidamental glands with prominent thin tip ( Fig. 5D View Figure 5 ).
