Aborsillus pora View in CoL sp. nov.

( Figs 1–8)

Holotype. Male, Argentina, Misiones, Parque Prov. Moconá, S 27° 09.185 ” W 53° 54.080 ”, 342 m, 2-X-2010, Montemayor col. ( MLP). GoogleMaps

Paratype. female, same data ( MLP) .

Diagnosis. Rostrum long, reaching abdomen; hemelytra with a medial transverse dark band; scutellum darker than head and pronotum.

Description. Male holotype ( Fig. 1): Total length 3.75. Head length 0.55. Head width 0.77. Scape 0.16, pedicel 0.28, basiflagellomere 0.32, distiflagellomere 0.43. Pronotal length 0.75, pronotal width 1.17. Rostral length: I 0.44, II 0.40, III 0.42, IV 0.31.

Antenna with short semierect silvery setae: scape, pedicelle, and basiflagellomere light brown, base of pedicelle and basiflagellomere dark brown; distiflagellomere dark brown. Head, pronotum, scutellum, hemelytron and pleura with short, adpressed, silvery setae. Head and anterior half of pronotum brown; posterior half of pronotum light brown; base of head, collar region, a longitudinal median stripe, humeral angles and scutellum dark brown almost black. Buccula light brown. Rostrum with scattered, short, semierect silvery setae, dark brown. Hemelytron ( Fig. 1) whitish, base and outer margins yellowish; clavus distally dark brown; corium with a medial transverse dark brown band and a dark reddish maculae distally; membrane hyaline. Pleura brown, acetabular areas, ostiolar peritreme and metaepimeron dorsally whitish. Legs with short decumbent silvery setae, light brown, pretarsus darker. Abdomen with abundant very short, adpressed, silvery setae with longer semierect setae ventrally; brown, pygophore lighter, connexiva black and white.

Head, pronotum, scutellum, and pleura coarsely punctuated.

Evaporative area large, occupying almost all of metapleuron except a narrow dorsal area, a large part of mesopleuron reaching its antero-dorsal margin, and medially all the thoracic sterna ( Fig. 3 View FIGURE 2, 3 ).

Pygophore as in figures 4a, b and 5. Parameres as in figures 6a, b, with many erect setae on shank extended basally on curved blade. Aedeagus as in figure 7.

Female. ( Figs 2, 3 View FIGURE 2, 3 ) Total length 3.90. Head length 0.70. Head width 0.83. Scape 0.17, pedicel 0.35, basiflagellomere 0.37, distiflagellomere 0.58. Pronotal length 0.83, pronotal width 1.33. Rostral length: I 0.45, II 0.37, III 0.42, IV 0.33.

Similar to male but larger and with darker femora. Pregenital abdominal sterna with a median sulcus.

Etimology. The specific epithet refers to the Guarani word porâ , meaning “cute, beautiful.”

Distribution. Argentina.

Discussion. The characters most valuable to distinguish A. pora from A. insignis are the length of the rostrum and the coloration pattern. In A. insignis the rostrum is shorter, never reaching the abdomen, the scutellum is concolorous with the pronotum and the head, and the hemelytra lack a medial transverse dark brown band.
