ABSTRACT. New seven species, Pterostichus (Morphohaptoderus) glabellus sp.n., P. (M.) primitivus sp.n., P. (M.) unisetosus sp.n., P. (Neohaptoderus) austrinus sp.n., P. (Vietosteropus) subirideus sp.n., P. (Vietoderus subg.n.) laevibasis sp.n., and P. (Phonias) batdaiensis sp.n., all from Vietnam, are described. Pterostichus (Circinatus) tonkinensis Straneo, 1980, is re-described based on fresh material. Interrelations of five subgenera of the Argutor lineage, including Phonias, are discussed based on external morphological characters, male and female genitalia and reproductive tract. A key to the subgenera of the lineage is provided. New synonymy is established: P. (Ph.) ussuriensis (Tschitschйrine, 1897) = P. burkhan Berlov et Anichtchenko, 2005, syn.n.

KEY WORDS: Coleoptera, Carabidae, Pterostichus, new subgenus, new species, Vietnam, Oriental region.
