Stenocaris minor (T. Scott, 1893) is a species complex composed of two species, S.
minor s. str. and S. minor sensu Cottarelli & Venanzetti (1989) (Kim et al., 2023).
Stenocaris minor sensu Apostolov (1971), S. minor sensu Marinov (1971), and S. minor sensu
Apostolov & Marinov (1988) from the Black Sea, and S. minor sensu Wilson (1932)
from North America should be relegated to species inquirenda in the genus (Kim et al., 2023).
Taxonomic review of the morphology of all Stenocaris species indicates that the
generic concept must be restricted to accommodate S. minor s. str., S. gracilis Sars,
1909, S. intermedia Itô, 1972, S. figaroloensis Kim, Cho, Yoon & Lee, 2023, and S. marcida Kim, Cho, yoon & Lee, 2023 (Kim et al., 2023).
