Gebiidea is an infraorder of decapod crustaceans. Gebiidea and Axiidea are divergent infraoders of the former infraorder Thalassinidea. These infraorders have converged ecologically and morphologically as burrowing forms. [1] Based on molecular evidence as of 2009, it is now widely believed that these two infraorders represent two distinct lineages separate from one another. Since this is a recent change, much of the literature and research surrounding these infraorders still refers to the Axiidea and Gebiidea in combination as "thalassinidean" for the sake of clarity and reference. [1] This division based on molecular evidence is consistent with the groupings proposed by Robert Gurney in 1938 based on larval developmental stages. [2]
The infraorder Gebiidea belongs to the clade Reptantia, which consists of the walking/crawling decapods ( lobsters and crabs). The cladogram below shows Gebiidea's placement within the larger order Decapoda, from analysis by Wolfe et al., 2019. [3]

Gebiidea comprises the following families: [4]
However, Axianassidae is sometimes considered to be a junior synonym of Laomediidae. [5] [6]
