Diagnosis. Rostrum flat, short, triangular, shorter than eyestalks, or spike-like, longer than wide; median carina absent; gastric carinae absent; cervical groove well defined; suture between ocular lobe and end of linea thalassinica oblique in lateral view; anterior branchiostegal lobe sclerotised, well produced anteriorly beyond junction with oblique branchiostegal ridge with which it articulates by means of a virtual condyle; posterior margin of carapace without lateral lobes; pleomere 1 without anterolateral lobes, weakly chitinised. Eyestalks flattened, contiguous, with subdistal dorsal cornea, or cylindrical, with terminal subspherical cornea ( Calliapagurops only). Antennal scaphocerite rudimentary. Maxilla scaphognathite without long seta on posterior lobe extending into branchial chamber. Maxilliped 1 epipod with acute anterior lobe lying alongside exopod. Maxilliped 3 dactylus slender, digitiform,

with setae irregularly spaced along all margins. Cheliped merus lower margin smooth or spinose; major cheliped with distinctively flattened palm, sometimes with strong crest above and below. Pereopod 3 propodus broad, with proximal lobe on lower margin, without distal spiniform setae on lateral face (often with 1 distal spiniform seta on lower margin). Pereopod 5 minutely chelate or subchelate. Female pleopod 2 rami narrower and with more reduced setation than pleopods 3–5; endopod flattened and 2–5 times as long as wide. Pleopods 3–5 with oblique peduncles meeting mesially, endopods triangular, with straight mesial margin, exopods attached laterally, proximally lobed, longer than and enclosing endopods; appendices internae reduced and almost embedded in mesial margin of endopod. Uropodal exopod with elevated dorsal plate.

Remarks. In callichirids, the endopod of the female pleopod 2 is flattened, variously broadened and more or less parallel-sided, unlike in callianassids where it is narrow. The anterior branchiostegal margin is interrupted by an oblique sclerotised ridge, sometimes almost articulating on the margin, unlike in callianassids where this margin is uninterrupted. Pleopod 1 is always present in the male, often substantial with a distolateral sharp curved lobe (fig. 15d–j) or variously reduced (fig. 15a–c), whereas in callianassids it is small and simple or absent. The epipod of maxilliped 1 takes the plesiomorphic form with a triangular lobe overlapping the exopod; this lobe does not exist in callianassids.

The use of the name as a family, rather than subfamily, has not been previously argued.
