Introduction

Ctenochelids are a diverse family of burrowing ghost shrimps united only by the unusual dactylus on pereopod 5. None is common. Apart from general observations about habitats nothing is known of their ecology. Some are from shallow sediments but others are known only from claws captured at depth. Genera formerly included in Ctenochelidae s.s. and Gourretiidae are included in the one family (Poore et al. 2019; Robles et al. 2020). Keys to species in Sakai (2011) are useful for some genera but his taxonomy differs markedly from that of the most recent comprehensive revision (Poore et al. 2019).

Diagnosis

Scaphocerite simple, triangular. Maxilliped 3 dactylus slender, digitiform. Pereopod 5 subchelate, dactylus a twisted plate longer than finger. Uropodal exopod without elevated dorsal plate, or with margin divided by notch.
