Abstract
Papiliolebias ashleyae n. sp. is described from Bolivia, departamento de Santa Cruz, Rio San Pablo, upper Mamoré basin. Papiliolebias ashleyae n. sp. is distinguished from other Papiliolebias species by a combination of characters: male overall color pattern of body, caudal- and pelvic-fins brownish red (vs. dark blue); transverse brownish red bars in dorsal and anal fins located between black and white bar at base of dorsal and anal fins and blue area in distal part of dorsal and anal fins (vs. absence of red-brown stripe on the remaining species of the genus, where the color of dorsal and anal fins is blue with a black stripe and white spots at the base of the fins); dorsal-fin origin at vertical through base of anal fin rays 9th-10th (vs. dorsal fin origin at vertical through base of anal fin rays 7th-8th in P. bitteri and 6th-9th in P. hatinne) and pelvic fins separated by small interspace of 4 mm (vs. not separated).
