Taxonomic review of the genus Korrigania Sanders et al., 2020 including a new species description, with comments on Tritonoranella Oyama, 1964 (Gastropoda: Bursidae)

The taxonomic status of Korrigania Sanders et al., 2020, of the family Bursidae Thiele, 1925, is reviewed. Prior to the present work, the genus included five recent species that demonstrate considerable morphological variation. Herein, the new species Korrigania stefanoelisa n. sp., from New Caledonia and Vanuatu, is added, and K. vianelloi Cossignani, 2023, so far only known from the Philippines, is designated as synonym of K. awatii (Ray, 1950) n. syn. The main morphological characters of Korrigania are described, together with those of the species included. Bursa humilis Beu, 1981 and Bursa natalensis Coelho & Matthews, 1970 are accepted as Tritonoranella humilis (Beu, 1981) n. comb. and Tritonoranella natalensis (Coelho & Matthews, 1970) n. comb.
