A new chalcidid genus, Mischochalcis (Hymenoptera: Chalcididae), is erected with the description M. enigmatus sp. nov. from the Western Ghats as the type species. An Afrotropical species, initially described in Haltichella Spinola, is transferred into the new genus as Mischochalcis inermis (Schmitz) comb. nov. The new genus belongs to the very diverse subfamily Haltichellinae and differs from other genera of the subfamily in having an obliquely truncate metatibia in which the truncation ends in a spine formed by the continuation of an additional carina. The systematic placement of Mischochalcis and its presence in two distant biogeographic realms showing disrupted distribution are discussed.
