Stenochiridae is a family of fossil decapod crustaceans which lived from the early Jurassic to late Cretaceous periods.

[1] However, Albert Oppel noted in 1861 that this genus name was preoccupied by a cnidarian, and split the two species into separate genera, renaming them as Pseudastacus pustulosus and Stenochirus angustus.

[3] In 1997, Tshudy and Babcock erected the new family Chilenophoberidae, of which Chilenophoberus was the type genus and three other genera (Pseudastacus, Palaeophoberus and Tillocheles) were assigned to.

[4] In 2013, a study on the phylogeny of lobsters by Karasawa et al. found that Stenochirus and Pseudastacus were sister taxa, which would make Chilenophoberidae a paraphyletic taxon with Stenochiridae nested within.

The cladogram below shows the placement of Stenochiridae within Astacidea, from analysis by Karasawa et al. (2013):[5] Parastacidae Cricoidoscelosidae Cambaridae Astacidae †Protastacidae Enoplometopidae †Uncinidae †Stenochiridae Nephropidae The cladogram below shows the internal relationships of Stenochiridae according to Karasawa et al. (2013):[5] Stenochirus Pseudastacus Chilenophoberus Palaeophoberus Tillocheles
