Paisana lydiae n. sp.

( Figs. 3, 16–20)

Description. Holotype male ( Fig. 3): Total length: 6.67. Head dark brown, clypeus brown; with abundant short silver decumbent setae; and longer semierect sparse setae dorsally. Head length: 1.12. Head width: 1.04. Antenniferous tubercles slightly divergent. Eyes slightly oval. Interocular space: 0.51. Ocelli located behind imaginary line through posterior margin of eyes, closer to eyes than to collar. Interocellar space: 0.29. Rostrum light brown, not uniformly pigmented, apex of article IV dark brown, with sparse erect setae. Rostrum reaching mesocoxae. Rostral length: article I 0.72, article II 0.85, article III and IV absent. Antenna long; scapus, pedicellus, and basal 2/3 of basiflagellomere light brown, rest of basiflagellomere and distiflagellomere darker, the latter with yellowish basal band extending over approximately half of segment length; with abundant short decumbent setae. Antennal length: scapus 0.58, pedicellus 1.20, basiflagellomere 1.12, distiflagellomere 1.28

Collar and anterior pronotal lobe dark brown; posterior lobe irregularly tinged with brownish hues, with four irregular longitudinal light brown bands. Pronotum with short decumbent setae, and long erect setae on anterior lobe. Length of collar, anterior pronotal lobe, and posterior pronotal lobe: 0.10; 0.62; 0.61, respectively. Width of collar, anterior pronotal lobe, and posterior pronotal lobe: 0.70; 1.09; 1.66, respectively. Scutellum dark brown; punctate; with short decumbent setae and long erect setae as on anterior pronotal lobe. Hemelytra brown, with anterior ¾ of corial margin and a subapical macula light brown; with short decumbent setae. Clavus with three rows of punctures and an incomplete fourth row of non-aligned punctures over distal 3/4 between inner and median rows. External corial margin slightly concave with anterior half serrated. Membrane brown, not uniformly pigmented. Pleura dark brown, with acetabular areas, proepimeron and metepimeron lighter; punctate and setose, with abundant decumbent short silver setae. Coxae dark brown with reddish hues [fore legs absent]; rest light brown, except subapical band on mesofemora and apical 1/3 of metafemora, brown. Legs with decumbent setae more abundant on distal tibiae and tarsi, and with semierect sparse setae.

Abdomen brown. Length: 3.06. Pygophore ( Figs. 16–17): anterior margin of dorsal aperture slightly concave; inner projections more developed posteriorly. In lateral view: dorsal margin not declivent posteriorly. Parameres ( Figs. 18–19): blade short and slightly curved; shank with inner projection, with setae on upper margin and basal portion of blade, outer projection with four long setae. Aedeagus as in figure 20.

Paratypes. Fore femora dark brown except basally and distally light brown; tibiae and tarsi light brown. Femora incrassate, with semierect setae and two rows of spines ventrally; tibiae with many small tubercles ventrally.

Distribution. Brazil.

Remarks. This species can be easily distinguished from others by the partially serrated corial margin. Moreover, the pygophore of P. lydiae the greatest width is in the distal third ( Fig. 16), in contrast in the other species the pygophore shows its greatest width medially ( Fig. 11, 21, 26).

Etymology. This species is named in honor of the author’s mother, Lydia María Albarello.
