Dicrania martinezi Frey 1972: 71   ; Evans 2003: 265 (catalog); Evans & Smith 2005: 223 (catalog), 2007: 225 (catalog), 2009: 228 (catalog).

Diagnosis. Body fusiform in lateral view, with green reflections; clypeus with denticle-like setae; elytral striae distinctly punctate.

Description. Body ( Figs. 1–3 View FIGURES 1 – 9. 1, 2, 4 ) fusiform in dorsal and lateral view, length 7.2 –8.0 mm, width 3.8 –4.0 mm at the middle of elytra. Color dark-brown on head and thorax, yellow on legs and abdomen; frons, pronotum, elytra with green reflections. Head ( Figs. 4 View FIGURES 1 – 9. 1, 2, 4 , 12 View FIGURES 10 – 16. 10 ) width 1.4–1.5 mm. Width of eye in dorsal view about 6.8 times narrower than interocular area. Epistomal suture straight. Frons and clypeus with denticle-like setae. Galea ( Fig. 25, 26 View FIGURES 17 – 27. 17 – 26 ) with 8 teeth. Pronotum ( Figs. 28–30 View FIGURES 28 – 39. 28 – 35, 37 ) length 2.4–2.6 mm, width 2.9–3.1 mm. Protarsal claws with anterior tooth narrower and longer than internal tooth. Scutellum as large as anterior elytral margin or near so. Elytral striae thickly punctate, female with smaller punctation. Posterior wing ( Figs. 52–60 View FIGURES 52 – 62. 52 – 60 ) with AP 3 + 4 conspicuous. Female metafemur slightly enlarged, without modified setae; male metafemur ( Fig. 35 View FIGURES 28 – 39. 28 – 35, 37 ) greatly enlarged, internodistal area with some teeth (1–3 teeth present and irregularly distributed on both legs), some of them with denticle-like setae; male tibiae ( Figs. 35, 37 View FIGURES 28 – 39. 28 – 35, 37 ) with ventroproximal indentation and a tooth. Parameres ( Figs. 64–66 View FIGURES 63 – 75. 63 – 69 ) with ventral side straight. Endophallus ( Figs. 67–69 View FIGURES 63 – 75. 63 – 69 ) with two darker lateroventral processes, temones thin and without V shaped piece. Female terminalia ( Figs. 72, 73 View FIGURES 63 – 75. 63 – 69 ). Proctiger indistinct; paraprocts thin; membranous lobe small; gonocoxite proximal pieces large and sparsely punctate and setose, distal pieces medially punctate and with setae in internodistal margin; gonostylus small, free, and densely setose.

Discussion. Compsodactylus martinezi   and C. scabrosus   have the anterior area of pronotum with denticle-like setae, pale elytra, and elytral striae distinctly punctate. The former can be easily distinguished by the larger size and body with green reflections.

Distribution ( Fig. 76 View FIGURE 76 ). Type series of C. martinezi   was collected in Abancay, Apurímac Department, Abancay Province, Peru. Abancay is located at an elevation of about 2400 m in southern Peruvian Andes. The other specimens examined were collected in Limatambo, Cuzco Province, northern limitary municipality to Abancay, Peru.

Natural history. Specimens of C. martinezi   were collected in Viguiera   ( Asteraceae   ), a Neotropical plant genus that occurs primarily in seasonally dry, arid, elevated areas ( Panero & Schilling 1988). The species of Compsodactylus   have setose mouthparts, slender mandibles, poorly developed incisor, small molar, welldeveloped prosteca; similar mouthparts were also found in Dicrania   and Macrodactylus Dejean, 1821   , two known genera that feed on flowers ( Borgmeier 1939; Ritcher 1966). This type of mouthparts has been associated with the consumption of soft part of plants, like flowers or soft fruits ( Krenn et al. 2005).

Type series. Frey (1972) described Dicrania martinezi   based in 5 3 and 3 ♀ collected by F. S. Pereira, 29.iii. 1968, in Abancay, Province of Apurímac, Peru. The holotype is housed at MACN, 2 paratypes (3, ♀) housed in NHMB (currently depository of the Frey’s collection). The current depository of the female allotype, and 4 paratypes (3 3, 1 ♀) is unknown. The original description also noted three paratypes in MZSP, but this material was not found.

Material examined. PERU: APURÍMAC, Abancay , 2,378 m, 29 March 1968, P. Pereira (collector), 1 3, 1 ♀ (paratypes) ( NHMB);   Mara , March 1968, Dehoa (collector), 23, 2 ♀ ( CMNC)   ; CUZCO, Limatambo, in Viguiera   , 4 March 1964, 2 3, 1 ♀ ( MZSP)   .
