( Figs. 7 –10 View FIGURES 1 – 9. 1, 2, 4 View FIGURES 10 – 16. 10 , 27 View FIGURES 17 – 27. 17 – 26 , 39 View FIGURES 28 – 39. 28 – 35, 37 , 61 View FIGURES 52 – 62. 52 – 60 , 70, 71, 75 View FIGURES 63 – 75. 63 – 69 , 76 View FIGURE 76 )

Diagnosis. Body fusiform in lateral view, without green reflections; clypeus with denticle-like setae; elytral striae distinctly punctate.

Description. Body ( Figs. 7–9 View FIGURES 1 – 9. 1, 2, 4 ) fusiform in dorsal and lateral view, length 6.3–6.5 mm, width 3.1–3.2 mm at the middle of elytra. Color of elytra dark brown, metatibia and metatarsus yellowish brown, pronotum sometimes with lateral yellowish brown coloration; or body yellowish brown with head and anterior area of pronotum dark brown. Head ( Fig. 10 View FIGURES 10 – 16. 10 ) width 1.3–1.4 mm. Width of eye in dorsal view about 7.2 times narrower than interocular area. Epistomal suture slightly sinuous. Frons and clypeus with denticle-like setae. Galea with 7 teeth ( Fig. 27 View FIGURES 17 – 27. 17 – 26 ). Pronotum length 1.8–1.9 mm, width 2.1–2.2 mm. Protarsal claws with anterior tooth narrower and longer than internal tooth. Scutellum as large as anterior elytral margin or near so. Elytral striae distinctly punctate. Posterior wing ( Fig. 61 View FIGURES 52 – 62. 52 – 60 ) with AP 3 + 4 inconspicuous. Male and female metafemur slightly enlarged; male with some long, erect, setae. Parameres ( Figs. 70–71 View FIGURES 63 – 75. 63 – 69 ) with ventral side rounded. Female terminalia ( Fig. 75 View FIGURES 63 – 75. 63 – 69 ). Proctiger indistinct, paraprocts membranous, membranous lobe wide. Gonocoxite pieces connate; proximal piece large, smooth, glabrous; distal piece shorter; internal and apical margin setose.

Discussion. Compsodactylus scabrosus   is similar to C. martinezi   , but smaller and without metallic green reflections. Compsodactylus scabrosus   and C. parvulus   have similar size, gonocoxite pieces connate, gosnostyle absent; however, the gonocoxite distal piece in C. scabrosus   is larger than in C. parvulus   .

Distribution ( Fig. 76 View FIGURE 76 ). The holotype and three paratypes of C. scabrosus   were collected in Payogasta, Salta Province, Argentina; a municipality located in the northwestern Argentine Andes, with elevation higher than 2500 m. One female paratype was collected in Province of Tucuman, Argentina, in “ciudad” locality, which probably refers to San Miguel de Tucuman, about 430 m, on the slopes of Aconquija mountains, a southwest extension of Andes.

Etymology. Scabrosus   (Latin), rough, scabrous; in reference to the head and pronotum denticle-like ornamentation.

Type series. Holotype labels: [ ARGENTINA, SALTA | Payogasta iii. 1992] [HOLOTYPE 3 | Compsodactylus   | scabrosus   | det. J. Fuhrmann, 2012] “red label”. Holotype without external damage and not dissected.   Allotype and   2 male paratypes with identical labels.   One female paratype with labels: [♀] [ Argentina | Tucuman | Ciudad xii. 1948 | A. Martinez leg.] [Pereira]   .

Material examined. ARGENTINA: SALTA, Payogasta , March 1992, 3 (holotype),   ♀ (allotype),   2 3 (paratypes) ( UFMT);   TUCUMÁN, “Ciudad” , December 1948, A. Martínez (collector), 1 ♀ (paratype) ( MZSP)   .
