abstract (from publication):
Papiliolebias hatinne sp. n. is described from a temporary pond 5 km north of Embarcación, in the río Bermejo basin, Province of Salta, Argentina. Papiliolebias hatinne sp. n. is distinguished from the only congener, P. bitteri, from the río Paraguay basin, by a combination of characters: 26-28 vertebrae, with 8-10 precaudal; second proximal radial of anal fin located between vertebrae 9 and 10 or 10 and 11; 1-2 vomerine teeth; an elongation of jaw suspensorium; first epibranchial somewhat triangular; 7-8 pelvic-fin rays; 12-13 pectoral-fin rays; 20-23 caudal-fin rays; males with anal fin turquoise blue, dorsal and caudal fins bluish, pelvic fin blue, and humeral spot metallic bluish green; females without dark dots on flanks. The chromosome formula is 2n= 28, FN= 36, integrated by two pairs of metacentric, two pairs of submetacentric and ten pairs of subtelocentric chromosomes.
