description: Compsodactylus scabrosus new species
(Figs. 7–10, 27, 39, 61, 70, 71, 75, 76)
Diagnosis. Body fusiform in lateral view, without green reflections; clypeus with denticle-like setae; elytral striae distinctly punctate.
Description. Body (Figs. 7–9) 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) 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). 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) with AP3+4 inconspicuous. Male and female metafemur slightly enlarged; male with some long, erect, setae. Parameres (Figs. 70–71) with ventral side rounded. Female terminalia (Fig. 75). 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). 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].
