Type material.

Holotype ♂, Peru: Peru, Department Cuzco, Manu Park, San Pedro, 1800 m, Mar. 1997, coll. local people. Deposited in MGCL. Additional examined specimens (1 ♂, MGCL): Peru: Same collecting data as holotype.

Etymology.

This species was found by my colleague and friend Andrei Sourakov when he was helping me locate additional specimens deposited in the MGCL, and thus I named it in his honor for his wonderful help.

Diagnosis.

Gaujonia sourakovi differs from other species mainly in coloration, having the most lightly marked forewing in this group. The male genitalia have the apex of the cucullus rounded, the saccular region is wide, and two patches of long hair-like spines on the vesica, differing from the others which have wider and well-developed spines.

Description.

Head. Last segment of palp black with some yellow scales; frons yellow, shaded with black scales. Thorax. Dark yellow with black dorsally. Wings. Forewing length: male 19-21 mm; forewing scales only on venation and margins; V-shaped mark at base of CuA2 widely open; dot in the middle of base of cell M1 elongated; orbicular spot small; veins lined with black; hindwing fringe black with dark yellow scales at end of each vein, whereas area on posterior margin of hindwing brown; a black line at base of vein M3. Leg. Prothoracic and mesothoracic legs dark brown with yellow scales on joints, whereas metathoracic legs dark yellow with some dark brown spots. Abdomen. Brown with scattered black scales dorsally, paler ventrally; long yellow scales laterally; black tufts with some yellow and brown scales on A1-A4. Male genitalia. Cucullar area narrow and curved with apex rounded; saccular region and process wide; juxta flat on upper side; tegumen wide; aedeagus 2 ⅔ × longer than wide; basal area of vesica 4 × longer than wide and vesica almost same width with two large patches of hair-like spines, one ovoid.

Immature stages.

Unknown.

Distribution.

The species Gaujonia sourakovi was collected in a deciduous forest at 1800 m elevation in southeastern Peru (Fig. 93 ).

Biology.

Unknown.

Remarks.

One specimen has the left forewing broken at the base and a brown patch on cell R5. Right wing with some brown patches near the outer margin between the cells R5-M2. In the other specimen the wings and left valva are broken, so it is not included as a paratype.
