Redescription of Pryteria colombiana Rothschild, 1933

Material examined (in MLC)

- 1 ♂, PANAMA, Panama, Los Altos de Cerro Azul , 14-XI-2023, 700 m, 9.2030° N 79.4150° W, L. & J. Harrison leg., dissected Gen. ML3848 (ligh-blue manuscript label).

- 1 ♀, same data but 15-XI-2023 .

Male ( Fig. 22)

FWL = 15 mm. The male morph dissected is close to form tenuis described from Belize. The forewings are pure white with two black bands. One follows the internal margin from base to tornus and the second is transverse from mid-costa to tornus. This last band is noticeably wider than the same in tenuis. The hindwings are entirely ivory except the anal margin which is widely blackish.

Genitalia male ( Fig. 23)

Genital capsule slightly asymmetrical, robust and well sclerotized. Uncus strongly sclerotized flattened with a longitudinal carina. Valvae strongly sclerotized in their terminal half, clearly outreaching the tip of uncus. The right one is narrower than the left one and slightly shorter. The two are strongly bent inward and narrowed in their terminal half. Their blunt and rounded tips are in a close vicinity above uncus. Juxta concave in middle. Vinculum evenly rounded with a rounded triangular saccus. In P. costata the uncus is shorter and shaped as a straight and pointed triangle. Aedeagus short, straight and cylindrical with a prominent caecum penis. Vesicaunilobed,bent at180° and coveredbyspiculesand tinycornuti are present near the extremity.

Female ( Fig. 24)

FWL = 17 mm. Morph close to morph apicella of Pryteria costata . The only difference is the total absence of blackish streaks in the apical area of forewings. The yellow lateral markings on abdomen are almost continuous whereas they are fragmented in apicella.
