Givira tristis Walker, 1856: 1527 . Type locality: [ Colombia, Muzo?]. In the original description, the type locality was not specified. However, Fletcher and Nye (1982) basing on the locality of catching another specimen from NHMUK, connected with the type specimen of Givira tristis , pre-installed the type locality as Colombia, Muzo ( Donahue, 1995). Type material (holotype male) in NHMUK, examined.

Material examined: Type material. Holotype ♂: [ Colombia, Muzo?], «1955/202», NHMUK 015106857, Genitalia slide №125 ( NHMUK) ( Figs 1 , 10 ).

Redescription. Length of fore wing 16 mm. Antenna bipectinate, rami short, antenna equal to 1/4 of fore wing in length. Thorax and abdomen densely covered with dark-brown scales. Fore wing brown, with poorly noticeable ocher spots along costal edge, hardly visible wavy pattern postdiscally and submarginally, dark-brown border, fringe brown. Hind wing ocher, with poorly developed wavy pattern of thin brown lines, brown stroke along veins A 1+2 and A 3 (in distal half), fringe brown.

Male genitalia. Uncus relatively short with club-like extension apically, apex with small semicircular incisure; tegumen conical; gnathos arms very short, ribbon-like; gnathos absent; valva cup-like with poorly curved costal and abdominal edge, outer edge semicircular, inner surface of the valva (in medium third) with poorly pronounced harpe shaped as small semicircular process; on sacculus—semicircular harpe with very wide base, densely covered with scabination; juxta robust with round aperture and long hood-like process; saccus small, semicircular, phallus about 1/2 of valva in length, spindle-like, vesica without cornuti.

Diagnosis. Externally, the species is practically indistinguishable from G. cinnamonea and G. modisma , but clearly differs in male genitalia: relatively short uncus with apical club-like extension and wide semicircular harpe on sacculus.

Distribution. Supposedly in Colombia.
