Bousquet, Yves, 2012, Catalogue of Geadephaga (Coleoptera, Adephaga) of America, north of Mexico, ZooKeys 245, pp. 1-1722 : 517

Subgenus Euferonia Casey, 1918

Euferonia Casey, 1918: 322, 365. Type species: Feronia stygica Say, 1823 by original designation. Etymology. From the Greek eu (well, by extension large) and the generic name Feronia [ q.v.], alluding to the large size ("usually rather large in size") of adults of these Feronia (= Pterostichus ) species [feminine].

Moritapterus O. Berlov, 2000: 4. Type species: Pterostichus thunbergi Morawitz, 1862 by original designation. New synonymy. Etymology. From the surname of the Japanese carabidologist Seiji Morita and the Greek pteron (wing, by extension elytron) [masculine]. Note. Sasakawa and Kubota (2006) listed this name in synonymy with Morphnosoma Lutshnik along with Euferonia Casey.

Diversity.

Eleven species in the boreal and temperate regions of eastern North America (six species) and Japan (five species: Pterostichus robustistylis Sasakawa and Kubota, Pterostichus sejunctus Bates, Pterostichus thunbergi Morawitz, Pterostichus tschitscherianus Jacobson, and Pterostichus tuberifer Sasakawa).

Identification.

Nicolay and Weiss (1934) and Lindroth (1966) summarily reviewed the North American species. A thorough revision of this group is needed.

Taxonomic Note.

This subgenus is often combined with Morphnosoma Lutshnik (e.g., Sasakawa and Kubota 2005; Lorenz 2005). The Japanese species are phenetically most similar to the North American Pterostichus lachrymosus (see Bousquet 1999: 137).
