ABSTRACT. The genera and species of Dryptina (Coleoptera, Carabidae, Dryptini) recorded in Vietnam are reviewed. Key for identification of the genus group taxa other than Neodrypta Basilewsky, 1960 is proposed. The review and description of these and some other new taxa of Dryptina are based on results obtained from a mental comparative analysis of morphological characters, including those of the mouthparts and of the male and female genitalia, examined in both type and available non-type species from the Paleotropical realm. The main results are as follows:
(1) Many Afrotropical and some Oriental species of the former genus Drypta Latreille, 1797, seem to be closer to those of the genera Nesiodrypta Jeannel, 1949, and Dendrocellus Schmidt-Göbel, 1846, than to the species of Drypta proper. They share the inner margin of the maxillary lacinia fringed with slender and dense setae, mostly combined with the elytra toothed at outer angles; for these species a new genus, Stenodrypta gen.n., is erected. In the Oriental region, it only includes S. cyanopa (Andrewes, 1936), comb.n., from India and S. dendrocelloides sp.n. from Vietnam.
(2) Afrotropical Dryptella Jeannel, 1949, stat.rest. et n., is resurrected from synonymy of Drypta and upgraded to genus level; it is defined chiefly by a particular setation of the maxillary lacinia, of which sparser and subequally enlarged setae are characteristic.
(3) Stenodrypta gen.n. and Dryptella are very distinct from both Drypta and Prionodrypta Jeannel, 1949, and slightly less so from Desera Dejean, 1825 (= Megarypta Sciaky et Anichtchenko, 2020, syn.n.), stat.rest., which genus is resurrected from synonymy of Drypta to combine three species from the Oriental region or southern China.
(4) A new Oriental genus, Dinodrypta gen.n., closely allied to Prionodrypta, is established for Prionodrypta mouhoti (Chaudoir, 1872).
(5) A new Afrotropical genus, Maxillodrypta gen.n., is erected for at least four, smaller-sized, species assigned formerly to Drypta and defined by the maxillary lacinia armed with setae sparse, uneven, and enlarged increasingly toward apex, combined with some minor features.
