Mastigimas peruanus Enderlein, 1921: 121 .

Material examined. Peru: 22 ♂, 13 ♀, Valle del Monzón, Tingo María, 23.ix.1954 (E. I. Schlinger & E. S. Ross) (CAS, NHMB, dry and slide mounted).

Description. Adult. Colouration. Straw-coloured or ochreous. In male dark brown or black patches in the middle of vertex, on toruli, occiput, on pronotum laterally, on mesopraescutum in the middle, on mesoscutum with four longitudinal stripes, a narrow dark band stretches from the edge of pronotum to the forewing base, mesosternum and abdomen. Mesonotum sometimes greenish. Compound eyes brown, ocelli orange. Antenna brown, lighter basally, getting gradually darker towards apex. Forewing transparent with brown veins and light or dark pterostigma; hindwing transparent, costal vein light brown. Fore and mid legs light brown with darker patches on femora. Metacoxa and metafemur brown to dark brown. Female similar but with less expanded brown elements restricted to thorax laterally and ventrally, as well as longitudinal stripes on mesoscutum and tip of terminalia.

Structure. Anterior head margin, in dorsal view, forming 'U'-shaped cleft between large toruli. Antenna 4.06– 5.46 (4.74±0.46) times as long as head width, segment 3 2.2–2.3 times as long as segment 4. Forewing ( Fig. 8 View FIGURES 3 – 11 ) 4.50–5.85 (5.09±0.58) times as long as head width, 2.25–2.42 (2.35±0.05) times as long wide, pterostigma long and narrow, ratio a/b 1.1, cell cu1 moderately high. Male proctiger 0.31–0.43 (0.36±0.05) times as long as head width. Paramere ( Figs 17 View FIGURES 12 – 19 , 25 View FIGURES 20 – 27 ) bifid, with large, angular outer lobe and smaller, apically flattened inner tooth-like tube. Distal portion of aedeagus ( Fig. 33 View FIGURES 28 – 35 ) moderately inflated apically, lacking apical hook. Female terminalia ( Fig. 41 View FIGURES 36 – 43 ) short; proctiger 0.88–1.07 (0.99±0.08) times as long as head width, and 2.50–2.80 (2.63±0.13) times as long as subgenital plate.

Measurements (4 ♂, 4 ♀, in mm). Body length 4.87–6.33 (5.60±0.46), head width 0.87–1.07 (0.93±0.07), antenna length 3.93–4.73 (4.37±0.23), forewing length 4.20–5.27 (4.68±0.39), metatibia length 1.13–1.53 (1.28±0.15), male proctiger length 0.27–0.40 (0.33±0.05), paramere length 0.20–0.27 (0.25±0.03), female proctiger length 0.87–1.00 (0.92±0.06).

Fifth instar immature unknown.

Distribution. Peru (Enderlein 1921; Burckhardt et al. 2011).

Host plant unknown.

Comments. Klimaszewski (1962) reported two specimens from Colombia as M. peruanus which were examined later by Brown & Hodkinson (1988) who suggested that they are M. cedrelae . Brown & Hodkinson (1988) concluded that M. peruanus may be a synonym of M. cedrelae . The material from Tingo María fits Enderlein's description of M. peruanus and there is no doubt that the two are conspecific. This material significantly differs from M. cedrelae (cf. identification key). We conclude that M. peruanus is distinct from M. cedrelae , and that the specimens from Colombia identified by Klimaszewski (1962) as M. peruanus are misidentified and belong to M. cedrelae .
