Redescription. ( Fig. 1) Head dark to dark brown with reddish hue, clypeus brown; with abundant, anteriorly decumbent, short silver setae, and longer, semierect, scattered setae dorsally. Antenniferous tubercles slightly divergent. Eyes slightly oval, with some setae between ommatidia. Ocelli located behind a line passing through posterior border of the eyes, closer to eyes than to collar. Rostrum brown, unevenly colored; apex of article IV dark brown; with scattered erect setae. With rostrum at resting position, article IV is situated on mesosternum, reaching mesocoxae in some specimens.

Scapus and pedicellus, and basal 2/3 of basiflagellomere light brown, rest of basiflagellomere and distiflagellomere darker, latter with a yellowish band measuring half of segment length or longer; with abundant, short, decumbent setae and scattered erect setae. Collar and anterior pronotal lobe dark brown; posterior pronotal lobe with brown hues, lateral margins and posterolateral angles light brown. Pronotum with short decumbent setae, and with some long erect setae on anterior lobe. In some specimens posterior pronotal lobe presents four irregular longitudinal light brown bands. Generally males have larger anterior pronotal lobe and profemora; in such cases rostrum reaching anterior border of mesosternum, whereas in females and males with smaller pronotum rostrum extends backwards and reaching mesocoxae. Scutellum brown to dark brown, punctate, with short decumbent setae and long erect setae similar to those of anterior pronotal lobe; with Yshape carina slightly bulky medially. Hemelytra with short decumbent setae. Clavus with three rows of punctures and a partial fourth over distal half between median and inner rows; color brown not uniformly tinged, apex light brown. Corium brown not uniformly tinged, anterior half of lateral margins and a subapical macula light brown; external corial margin slightly concave. Membrane brown, unevenly pigmented. In some specimens hemelytra not attaining apex of abdomen. Pleura dark brown, acetabular areas, and metepimeron lighter, with reddish hues in some specimens; punctate, with abundant short silver decumbent setae.

Protibiae with numerous minute tubercles over ventral surface; males with four equidistant spines bearing a setae on distal half, proximal spine largest. Coxae dark brown with reddish hues, rest light brown; pretarsi and meso- and metatibiae basally darker and with dark brown regions as follows: a wide band on 2/3 of profemora length (in some specimens profemora mottled and fringe less defined), a distal fringe and apex on meso- and metafemora, and apex of tibiae. Legs with decumbent setae, more abundant on tibiae distally and tarsi, and semierect sparse setae.

Abdomen brown to dark brown. Pygophore ( Figs. 6–7): anterior margin of dorsal aperture rounded; inner projections subtriangular. In lateral view: dorsal margin slightly declivent posteriorly; with two faint protuberances posteroventrally. Parameres ( Figs. 8–9): blade short and slightly curved; shank with an inner projection, with setae on upper margin and on basal portion of blade, outer projection with three long setae. Aedeagus ( Fig. 10) without spines; vesica with two lobes, irregularly sclerotized; ejaculatory reservoir with small wings, vesica and conjunctiva slightly sclerotized distally.

Distribution. Argentina (FIRST RECORD), Brazil.

Remarks. P. brachialis is very similar to P. pampeana ; see remarks of P. pampeana to distinguish these species.

Studied material. Lectotype: ♀, Brazil, designated by G. G. E. Scudder (1977: 30) ( SMNH) [very poorly preserved, abdomen pinned, head and thorax with legs embedded in glue on a separate pinned cardboard,

hemelytra glued separately to same cardboard].
