Miers states that Achseopsis is distinguished from Inachus " merely by having 

 the postocular as well as the prseocular spine distinctly developed, and by the more 

 or less falciform dactyli of the three posterior ambulatory legs." From A. spinulosus, 

 Stimpson, 1857, he says that his own A. giintheri, 1879, is distinguished " by having 

 but a single very long perpendicular spine on the gastric region." Like these, A. 

 superciliaris , Ortmann, 1893, has the rostrum not deeply divided. From Inachus 

 and Achaeopsis Miers considered Lispognathus " distinguished by the well-developed 

 rostral spines." For that genus Perrier notices as also characteristic the long 

 slender ambulatory legs. Miss Rathbun, however, in 1911, without discussion, sinks 

 Lispognathus, and by inference also Dorynchus, as synonyms of the earlier Achseopsis.
