Material examined: Type material. Holotype ♂: Paraguay: Boquerón department, Cruce Filadelphia , 22°29′S 60°00′W, 23-25.VI.2017, leg. U. Drechsel, genital preparation №370 Naydenov. A.E. ( ZISP); Paratype 1 ♂: Paraguay: Presidente Department, Chaco Lodge, 22°30′S 59°18′W, 5−6.VIII.2017, leg. U. Drechsel, genital preparation №371 Naydenov. A.E. ( RYB) .

Description. Wingspan 25 mm. Length of fore wing 12−12.5 mm. Fore wing brown at root and along costal edge, other portions of wing light-brown, fringe brown unicolorous. Hind wing light-yellow, without pattern, with thin brown border, fringe brown.

Male genitalia. Configuration typical for genus representatives: uncus short, pyramidal; gnathos arms very short, not fused; valve wide, lobe-like, basal end of costal edge strongly curved and sclerotized, costal edge poorly curved, with small notch in medium third, outer edge obliquely cut, almost smooth; abdominal edge poorly curved; saccus robust, trapezoidal, with small mastoid process apically; juxta slitshaped, tiny; phallus 1.5 shorter than valve, slightly narrowing from basal part to apex, poorly curved along its entire length.

Female unknown.

Diagnosis. The new species clearly differs from the other species externally and in the male genital structure details:

- from all the species, it differs in the practically reduced pattern on the fore wing;

- in Givarbela steinbachi and G. drechseli the outer end of the valve is strongly extended;

- in G. decolorata the outer edge of the valve is semicircular.

Distribution. Paraguay: Boquerón and Presidente Departments.

Etymology. The new species is named after Harrison Gray Dyar Jr. (1866–1929) ( Heinrich 1929). He was an American entomologist who described over 40 new species Cossidae from North and South America.
