Diagnosis. Paraprocts similar to L. lutea but the spines of the right paraproct are shorter and are placed on the internal basal border ( Fig. 23 ). L2 and via are disposed in an almost right angle ( Fig. 24 ). The scale zone sz ( Figs. 26 , 71 ) occupies less than half of the sclerotized surface.

Male. Measurements in mm. N= 8. PL: 3.40‾4.36 (3.72); TeL: 13.85‾18.73 (18.73); TL: 17.67‾22.07 (19.73); IO: 0.50‾1.00 (1.00); IOc: 0.40‾0.80 (0.80); IA: 0.80‾0.90 (0.90). Supra anal plate with an apical straight margin ( Fig.22 ). Paraprocts: similar to L. lutea but the spines of the right paraproct are shorter and are placed on the internal basal border ( Fig. 23 ). L2 and via are disposed in an almost right angle. Via slender and slightly curved uniformly ( Fig. 24 ). L3 hook shaped, with an apical incision ( Fig. 25 ). R1P with a quadrangular posterior area sclerotized with scale zone included. The scale zone sz occupies less than half of the sclerotized surface ( Fig. 26 ).

Female. Unknown.

Etymology. From the Province of Tucumán.

Distribution. Argentina-Provinces of Salta and Tucumán.
