Introduction

Eucalliacids are a family of ghost shrimps that shares with Callianopsidae a dilated, truncate dactylus on maxilliped 3, with a dense field of setae on its distal margin. They differ in possessing a dorsal plate on the uropodal exopod, and a smooth lower margin of the merus of the cheliped (Poore et al. 2019; Poore 2021). The shrimps inhabit permanent burrows usually on intertidal sandflats or shallow soft sediment but species of one genus inhabits the moderately deep-sea.

Diagnosis

Rostrum flat, triangular, shorter than eyestalks (Fig. 9.20a, b). Scaphocerite rudimentary. Maxilliped 3 propodus about as wide as long; dactylus broad, with dense field of setae on truncate distal margin. Uropodal exopod with elevated dorsal plate.
