Etymology.

The term bichu is used to refer to an insect or small animal in the Quechua language. Since this is the smallest species of Gaujonia , this name seems appropriate.

Diagnosis.

Gaujonia bichu is closely related to G. sourakovi , but G. bichu is the smaller. The male genitalia have the valva and the saccular region narrow, and the process of the sacculus is longer and thinner.

Male yellow with thin spots and lines on venation; forewing length: male 15-17 mm; forewing with two V-shaped marks on base of R1+R2 and R4+R5; base of cell with small black dot on M1; five black dots on Sc+R1 with a line right on apex; half of posterior margin black; hindwing with fringe black, interrupted by a yellow dot at end of each vein. Leg. Prothoracic leg black with femur and tarsi presenting yellow spots; mesothoracic legs yellow with some black spots; metathoracic legs yellow. Abdomen. Grayish yellow with yellow and black tufts in middle of abdomen dorsally on A1-A5, remainder of abdomen covered in yellow scales. Male genitalia. Valva long and narrow a little swollen from middle to apex externally; sacculus narrow; sacculus process long and narrow; juxta shield-like; tegumen wide, narrower near valva; aedeagus short and narrow; vesica elongated with two oval patches, one 2 × longer than the other.
