Paciforchestia Bousfield, 1982 is redefined to receive solely the type species, P. klawei (Bousfield, 1961), and Pyatakovestia gen. nov. is erected to accommodate the two species previously assigned to Paciforchestia sensu lato and two new species from Japan: P. pyatakovi (Derzhavin, 1937), P. gageoensis (Kim and Min, 2013), P. iwasai gen. et sp. nov. and P. boninensis gen. et sp. nov. Paciforchestia sensu stricto is characterized by having: elongate antenna 1, 5-dentate
lacinia on left mandible, mediodistally lobate palp article 2 on maxilliped, deeply subchelate gnathopod 1 (both sexes), cuspidactylate pereopods, moderately reduced pleopods with 3? retinacula, elongate dorsolateral robust seta of peduncle and marginally robust-setose outer ramus on uropod 1. Pyatakovestia gen. nov., inhabiting supralittoral zones to coastal and mountain forests in Japan, is distinguished from Paciforchestia sensu stricto by the stepped outer margin on maxilliped precoxa, deep coxae, strongly reduced pleopod rami, and distally truncated (or rounded) urosomite
3. Three species within Pyatakovestia: P. gageoensis, P. iwasai and P. boninensis, are characterized by having marginally bare outer ramus on uropod 1. Pyatakovestia gageoensis is peculiar in having
inflated dactyli on pereopods 3–5; P. boninensis in having strongly robust-setose margin of both rami on uropod 2.
