Genus Callianassa Leach, 1814

Type species: Cancer Astacus subterraneus Montagu, 1808, by original designation.

Remarks. The taxonomic history of the genus is convoluted; for various concepts see e.g. Manning & Felder (1991), Sakai (1999, 2005, 2011), Ngoc-Ho (2003), and Poore et al. (2019). For a long time, it has been the common catch-all genus for many extant species whose systematic position was uncertain ( Poore et al. 2019). In a similar way, throughout the palaeontological literature Callianassa is used as a collective name; for more details a reference is made for Hyžný & Klompmaker (2015). In his major work on middle Miocene (Badenian) decapods, Müller (1984) was well aware of difficulties of taxonomic evaluation of callianassid shrimps and used “ Callianassa ” with a notion of its unclear status. Herein, the genus is used in its revised concept of Poore et al. (2019).
