Diagnosis: Body soft, but not fragile. Rostrum short, with basal slit; apex distinctly overreaching anterodorsal margin of carapace. Carapace acutely carinate with shallow depression at each side of rostral base ( Fig. 4A, BView FIGURE 4). Branchiostegal sinus deep; branchiostegal spine small, marginal ( Fig. 4AView FIGURE 4). First pereopod with 4–8 spines on merus, unarmed on ischium and basis, posterodistal angle of basis produced, but not dentiform ( Fig. 4CView FIGURE 4). Second pereopod with 13–24 spines on merus, 0–1 spine on ischium and 1–7 spines and posterodistal tooth on basis ( Fig. 4DView FIGURE 4). First abdominal somite with dorsal carina on distal half; second to fifth abdominal somites carinate; sixth abdominal somite with dorsal carina on proximal half ( Fig. 4E, FView FIGURE 4). Telson grooved in dorsal midline, posterior margin moderately or deeply forked, with 8–12 pairs of spines ( Fig. 4G, HView FIGURE 4); telson shorter than sixth somite. Pleurobranch on the eighth thoracic somite (modified from Hayashi, 2006a).

Distribution: Type locality: Atlantic Ocean, South Greenland (unknown location). Southern Canary Islands, South Carolina (American coast) and Angola. New record: Brazil (Espírito Santo). Depth: 250 – 2400m.

Remarks: Pasiphaea tarda  is included in P. alcocki  species group and differs from its close related species Pasiphaea multidentata Esmark, 1866  by the basis of second pereopod with 2–4 spines ( Fig. 4DView FIGURE 4) vs. more than 6 spines ( Fig. 4AView FIGURE 4) ( Matthews & Pinnoi, 1973).
