Schmidt, Joachim & Will, Kipling, 2020, A new subgenus for “ Acalathus ” advena (LeConte, 1846) and the challenge of defining Calathina based on morphological characters (Coleoptera, Carabidae Sphodrini), Zootaxa 4722 (4), pp. 326-338 : 333

Subgenus Neocalathus Ball & Nègre, 1972

Third antennomere without pubescence. Mentum tooth bifid. Pronotal laterobasal seta situated at margin or removed from side margin. Lateral bead of prosternal process present. Parascutellar seta present. Elytra glabrous, with 2-7 discal setae in the third interval; discal setae absent in the fifth and seventh intervals. Elytral microsculpture nearly isodiametric. Metepisternum elongated or short. Male protarsomeres dilated. Lateral grooves present or absent on metatarsomeres I-IV. Apical gonocoxite variable, moderately elongated to short, with two ensiform setae at external margin (two or more setae based on Ball & Nègre 1972); sensory pit of apical gonocoxite well developed. Aedeagus left side up in repose; median lobe apical disc present; apical hook of long paramere present; membranous lobe of short paramere present.

The following two species are included in Neocalathus by previous authors. However, because they do not fit all of the character states of this subgenus as listed above, they are considered here separately.
