Tetralidia viracocha  sp. nov.

( Figs 12 –22View FIGURES 12 – 22, 25– 26View FIGURES 23 – 26)

Diagnosis. Subgenital plates, in ventral view ( Fig. 17View FIGURES 12 – 22), strongly narrowed at apical two-thirds; connective ( Fig. 19View FIGURES 12 – 22) Y-shaped; aedeagus ( Figs 21–22View FIGURES 12 – 22) with two pairs of lamellae on shaft, one lateroventral and one laterodorsal preapical; anal tube ( Fig. 16View FIGURES 12 – 22) with basiventral processes strongly curved posteriorly.

Measurements (mm). Male holotype: total length 7.2; crown median length 0.75; transocular width 1.41; interocular width 0.87; pronotum median length 0.65; width between humeri 1.67; mesonotum median length 1.31; mesonotum maximum width 1.25; forewing length 6.3; forewing maximum width 1.75.

General color. Body ( Figs 25–26View FIGURES 23 – 26) with ground color pale yellow. Crown ( Figs. 12View FIGURES 12 – 22, 25View FIGURES 23 – 26) with two pairs of orange maculae, maculae of anterior pair subtriangular close to anterior margin, and other pair of maculae at basal half, subquadrangular, adjacent to compound eyes. Frons ( Fig. 13View FIGURES 12 – 22) without maculae. Pronotum ( Figs 12, 14View FIGURES 12 – 22, 25–26View FIGURES 23 – 26) yellow, without stripes. Forewings ( Figs 15View FIGURES 12 – 22, 25– 26View FIGURES 23 – 26) yellowish and hyaline, without maculae. Legs yellow ( Fig. 26View FIGURES 23 – 26), with concolorous setae.

External morphology. External morphological characters as in generic description, except: forewing ( Figs 15View FIGURES 12 – 22, 25– 26View FIGURES 23 – 26) about 3.6 times longer than maximum width; venation weakly visible, except apically.

Male terminalia. Pygofer ( Fig. 16View FIGURES 12 – 22), in lateral view, produced; each lobe higher than long; posterior margin straight; apex rounded with few microsetae. Subgenital plates, in ventral view ( Fig. 17View FIGURES 12 – 22), with basal four-fifths fused; enlarged at base and strongly narrowed towards apex; ventral surface with few preapical setae; apices rounded; in lateral view ( Fig. 18View FIGURES 12 – 22), approximately as long as the pygofer; not curved dorsally; dorsal margin with numerous setae on basal third. Connective ( Fig. 19View FIGURES 12 – 22) Y-shaped; approximately two-thirds length of styles; arms as long as shaft. Styles ( Figs 19–20View FIGURES 12 – 22) without preapical lobe; apex sclerotized and strongly truncated, moderately curved ventrally; with setae on ventral preapical portion. Aedeagus ( Figs 21–22View FIGURES 12 – 22) long and narrow; shaft slightly sinuous with two pairs of lamellae, one longer lateroventral and one shorter laterodorsal preapical; apex with dorsal surface concave and curved ventrally; preapical gonopore. Anal tube ( Fig. 16View FIGURES 12 – 22) membranous, with pair of elongated basiventral processes strongly curved posteriorly.

Female unknown.

Etymology. The new species epithet alludes to creator god of Inca mythology.

Material examined. Male holotype: “ PERU: Cusco 3 rd km E\ Quincemil 13 ° 13 ’03”S \ 70 ° 43 ’ 40 ”W, 633m \ 20.viii-01.ix. 2012, Malaise\ R.R. Cavichioli; J.A. Rafael; A.P.M. Santos & D.M. Takiya” ( MUSM).

Notes. Tetralidia viracocha  sp. nov. is similar to T. admirabilis Marques-Costa & Cavichioli 2008  , in having the subgenital plates enlarged at the base and strongly tapering towards the apex and the styles with truncated apices. However, it can be easily distinguished from this and other species of the genus by the aedeagus with two pairs of lamellae on the shaft and the anal tube with basiventral processes strongly curved posteriorly.
