[1] The genus name honors Isabelle Gordon of the British Museum (Natural History) for her contributions to crustacean taxonomy.

[2] A major revision of Gordonopsis was published in 2020 by Peter K. L. Ng and Bertrand Richer de Forges, recognizing 8 valid species:[2] Species of Gordonopsis are characterized by a longitudinally ovate or polygonal carapace that is slightly wider than long.

[1] The dorsal surface of the carapace is distinctly convex in lateral view and covered in setae.

[2] Gordonopsis crabs are found exclusively in the deep sea, typically at depths of 300 to over 2,000 meters.

[6] The genus has an Indo-West Pacific distribution, with species recorded from the Indian Ocean (Andaman Sea, Bay of Bengal) and the western Pacific Ocean (South China Sea, Philippines, Indonesia, Japan, Papua New Guinea).
