Diagnosis
Terminal antennomere slightly curved in distal portion; metaventral process long, slender, parallel-sided with two separate setae; composite tergite in posterior portion with pair of short, triangular, sharp projection which are not exceeding posterior margin of abdomen; mesotibia modified in distal portion; aedeagus strongly elongate, 2.95 × as long as wide; endophallus with large sclerite.
Etymology
Patronymic, named after my good friend and an excellent collector of litter-dwelling beetles, Peter Baňař, Brno, Czech Republic, who collected many interesting pselaphines in Madagascar.
