Hypoxys saltensis sp. n.

(Figures: 3, 10E –F, 12)

Etymology. The specific epithet refers to Province of Salta ( Argentina) where the specimens collected.

Holotype. ARGENTINA. Province of Salta: 1 ♂ Quebrada of San Lorenzo , [Quebrada of Catayete, Province of Salta?], 10.II.1953, R. Foerster Coll. ( MMB).

Measurements. Total length 13.6; total width 6.6; head length 1.4; head width 3.0; interocular distance: 1.6; length of antennomeres I: 0.9; II: 0.7; III: 1.4; IV: 2.5; V: lost; pronotum length 2.6; pronotum width 7.7; scutellum length 5.7; scutellum width 4.4.

Diagnosis. Second antennomer smaller than the others (II<I<III<IV).Anterolateral margin of pronotum punctured ( Fig. 10E ). Scutellum with punctures of the same size ( Fig. 10E ). Hemelytrom membrane transparent ( Fig. 10E ). Metasternal process with arms of anterior bifurcation receiving 2/3 of third rostral segment ( Fig. 10F ). Pseudosutures of abdomen without adjacent dark green spot ( Fig. 10F ). Male genitalia. Dorsal surface with spot extending about ½ of the length of the pygophore ( Fig. 3A ). Dorsal rim with lateral expansions level with posterolateral angles and rounded ( Figs. 3A, 3C ). Superior process of the genital cup elliptic, face rough in posterior view ( Fig. 3B ). Paramere spearhead-shaped, lobes slightly developed, apex truncated ( Figs. 3B, 3D ). Proctiger strongly excavated laterally, excavation covered by long and dense setae; dorsal face tapering posteriorly; posterior face subpentagonal, basal third constricted ( Figs. 3B, 3D ). Inner wall with swollen area large and close to posterolateral angles ( Fig. 3D , black arrow). Ventral rim strongly excavated, U-shaped; expansions ending laterally in a rounded projection ( Fig. 4C ). Female genitalia. Unknown.

Distribution ( Fig. 12 ). ARGENTINA: Salta.

Comments. The species H. subrastratus , H. myrtacivorus sp. n. and H. saltensis sp. n. share the proctiger strongly laterally excavated and tapered posteriorly. The species H. saltensis sp. n. differs from the other species of the group H. triangularis by anterior and posterior lobes of the paramere barely developed, giving a spearhead shape.
