Diagnosis. Oostpila astigma and O. albipunctulata which is described below, share roundish hind wings but the latter has a smaller wingspan. O. delacruzi and O. leucostigma differ in roundly angulate hind wings.

Description. Wingspan, 18–22 mm (Fig. 18). The frons is red-brown, the interantennal fillet white, with a red line across the vertex. The palpi are light brown, short, not exceeding frons. Male antennae are light brown, pectinate, the length of the external and inner pectinations on the tenth antennal segment is 0.75 and 0.5 mm, accordingly. The thorax is green dorsally, the metathorax with a white spot which includes some red scales, the abdomen mottled beige and reddish. The tergites A1–A5 are crested, the anterior crests dark brown with some black hairscales, the posterior crests getting gradually paler. The hind tibiae are slender with one (distal) pair of spurs, without a hair pencil. The ground colour of wings is medium green. The fore wing costa is broadly lined in light brown and densely irrorated with brown. The blotches to the wing apex and the tornus of both wings are also light brown with brown irroration, which tends to concentrate in some fine, parallel strigulation. The fore wing apical blotch extends to the costa apex, in the East Bolivian specimens somewhat broader than in the Peruvian populations. The fringe is light brown, chequered, darker at vein ends. The discal spots are lacking on the fore wings, but are small and beige on the hind wings. The marginal line is blackish brown, the blotches on both wings are edged by a broad white line, which is accentuated basally by a thin, interrupted blackish line.

Male genitalia (Fig. 54): Male genitalia well match the description by Cook & Scoble (1995: 24, 88, Fig. 97). The socii are slender with rounded tips, and the valvae are slender, with a deep subapical incision, the apical lobe being roughly setose along its ventral (or inner) margin, the valve costa is rounded or angulate dorso-distally. The sacculus is without any ornamentation, straight-edged distally. The juxta is V-shaped, its dorsal parts are fused with sacculi and are connected to the transtilla by means of short lateral projections, the transtilla projecting dorsally long and rounded. The saccus is broad, rounded, slightly emarginated medially. The aedeagus is as long as the valva, smooth and distally thinner. The distal margin of sternite A8 is roundly bilobed. The East Bolivian specimens show narrow aedeagus and short juxta. Female genitalia unknown.

Genetic data. BIN BOLD:ADL1762 (n=1 from Bolivia). Nearest neighbour on BOLD: Oospila leucostigma from Ecuador (10.4%).

Distribution. Peru (locus typicus: south-eastern Peru: Puno), Colombia ( Cook & Scoble 1995; own data), new country record: Bolivia.

Biology. The specimens were collected in tall montane tropical forest in September, October and December.
