Palm much shorter than fingers, with tuft of short setae at middle of ventral surface; short, distinct groove on ventral surface proximally. Carpus cupped distally to receive palm, with acute or subacute ventrodistal tooth; dorsodistal mesial margin rounded; ventromesial surface with patch of dense setae and 1 small spine just proximal to setal patch; mesial face shallowly depressed. Merus and ischium strongly obliquely articulated in lateral view; merus slightly inflated ventrally; ischium always unarmed.

) as in other congeners. The posteroventral margin of the fourth abdominal pleuron varies from rounded to sharply pointed. The fifth abdominal pleuron is always armed with a strong posteroventral tooth and with one to four small additional teeth or denticles on the posterior margin. The antennal scale may be proportionally longer in males than in females. The stoutness of the cheliped of the first pereopod in alvinocaridids is known to vary allometrically but is usually not sexually dimorphic (

Shared characters include: the relatively robust body form; rostrum generally with one subterminal tooth or unarmed on the ventral margin; the possession of a row of plumose setae on the posterior margin of the telson; and a tendency for reduction of armature on the meri and ischia of the third to fifth pereopods. There are a few subtle morphological differences between the two species. The postrostral median ridge on the carapace extends beyond the midlength of the carapace in
