Abstract: Chalarus Walker, 1834 (Diptera: Pipunculidae: Chalarinae) has a cosmopolitan
distribution, with 11 known species in the Neotropical Region, but none
recorded in Colombia. Two new species of Chalarus are described from Colombia,
namely Chalarus boyacensis sp. nov. (type locality: Cabaña Chaina, Santuario de
Fauna y Flora Iguaque) and C. chairensis sp. nov. (type locality: Vereda Tigrera
Alta, Cartagena del Chaira). Chalarus absonus Rafael, 1990, C. delicatus Rafael,
1990 and C. connexus Rafael, 1988 are recorded in Colombia for the first time,
with amended and comparative diagnoses. Photographs of five South American
species, distribution map and a dichotomic key to males of all Neotropical
species are included.
