One of 368 myrmecophilous species in the carabid genus Paussus.

Diagnosis

This new species is allocated to the subgenus Scaphipaussus Fowler 1912 according to the groups key of Robertson & Moore (2016). Within this subgenus the new species is unique with regard to the combination of the following characters: body lustrous, scatteredly and shortly pubescent, seeming hairless to the naked eyes; head vertex distinctly excavated, laterally bordered by auriculate costae; scape longer than wide, cylindrical; fused flagellum elongated subtriangular, with dorsal margin of outer side with five robust teeth and five deep incisions, while ventral margin of that with five weak protrusions and five weak emarginations; pronotum wider than long, width/length = 1.22, as wide as head, (anterior part width)/(posterior part width) = 1.10, anterior part laterally angulate, posterior part with lateral margins roundly protruded in the apical 3/4 and obliquely substraight in the basal 1/4; elytra not bearing lateral trichome fringes; legs robust; pygidium with posterior dorsal margin distinctly upturned and explanate, marginal trichome fringe dense
