Diagnosis. Member of Group II, subgroup C of Mockford (1991), that includes P. bimaculatus Enderlein, P. delunatus Roesler, P. fasciatus Banks, P. fastosus Roesler, and P. quadriguttatus Enderlein, differing from them in that the forewing has two posterior colorless areas, and a large, central colorless area, from the anterior end of the pterostigma to the middle of cell M; the hindwing has a pigmented band from R1 to Cu, ascending on both sides of it as far as the junction with M (Fig. 2).
Color. Body medium brown. Compound eyes black, ocellar field ochre. Maxillary palps and legs pale brown. Antennae with scape, pedicel and f1 creamy white, flagellomeres f2-f11 creamy white, with apices brown (Fig. 4). Forewing (Fig. 2) brown, with colorless areas as described in the diagnosis. Hindwing (Fig. 2) almost hyaline, with peripheral brown band as described in the diagnosis. Abdomen creamy white, with dark brown subcuticular bands on tergum, little pigmented on venter.
Morphology. Lacinial tip typical of the genus, bicuspid, with high, rounded lateral cusp and short, median cusp. Forewing membrane with a field of marginal setae, from pterostigma to areola postica. Pterostigma rounded posteriorly, R2+3 and R4+5 diverging from a point, Rs-M joined by a short crossvein. Areola postica about twice as long as the distance from nodulus to Cu1b. Hindwing Rs-M diverging from a point (Fig. 2). Hypandrium broad (Fig. 6), with a distint median lobe, setae as illustrated. Phallosome (Fig. 3), with external parameres bearing pores apically, aedeagal arch tapering to slender apex; endophallus distinct, with “finger print” marks anteriorly, delimited on sides by strongly pigmented asperous bands. Paraprocts large, rounded (Fig. 5), with setae as illustrated and sensory fields semi-elliptic, with 27 trichobothria issuing from basal rosettes. Epiproct (Fig. 5) high, trapeziform, with setae on distal half.
Measurements. FW: 4137, HW: 3121, F: 753, T: 1265, t1: 443, t2: 144, ctt1: 23, Mx4: 185, f1: 569, f2: 477, f3: 402, f4: 383, IO: 295, D: 361, d: 250, IO/D: 0.81, PO: 0.69.
Material studied. Holotype male. ARGENTINA, Jujuy Province, Department of Valle Grande, San Francisco Valley, N of Abra de Cañas, moss forest, 23°40.5’S: 64°54.01’W, 1680m., 25.X.2006, Gyorgy Sziráki, E. Hórvath, & E. González Olazo (HNHM). Paratype male. Department of Ledesma, Calilegua National Park, Abra de Cañas, moss forest, 23°44.2’S: 64°54.1’W, 1700m., 25.X.2006, same collectors (HNHM).
Etymology. The specific name refers to the Province of Jujuy, in northwestern Argentina, where the types were collected.
Remarks. P. jujuyensis differs from the other five species in its group (see diagnosis), in fore- and hindwings pigmentation pattern, in having a distinct endophallus, and in having a unique hypandrium with a median lobe. P. bimaculatus Enderlein is Chilean, P. delunatus Roesler and P. fastosus Roesler occur in southeastern Brazil, P. fasciatus Banks is Caribbean, and P. quadriguttatus (Enderlein) occurs in Cuzco, Peru.
