Promachoteuthis sulcus is a species of promachoteuthid squid. It is distinguished from related taxa on the basis of several morphological features: nuchal fusion between the head and mantle, much larger size of arm suckers compared to club suckers, greater width of tentacle base than arm base, a recessed club base, and the presence of an aboral tentacle groove.
P. sulcus is known from a single specimen caught by the German research vessel R/V Walther Herwig in an open net off Tristan Da Cunha, southern Atlantic Ocean (), at a depth of 1750–2000 m.
