Introduction

Strahlaxiids are intertidal and shallow-water shrimps distinguished from axiids by the triangular rather than elongate exopods on pleopods 3–5 and a bifid rostrum (Poore 1994). Unpublished research suggests that the family contains only Strahlaxius and that Neaxius belongs elsewhere.

Diagnosis

Rostrum triangular, apically bifid, with lateral teeth; median carina present as ridge or row of spines extending over gastric region. Posterior margin of carapace with lateral lobes interacting with anterolateral lobes on pleonite 1. Eyestalks cylindrical, with terminal subspherical cornea. Scaphocerite elongate.
