( Figures 14–30 View FIGURES 14–19 View FIGURES 20–27 View FIGURES 28–30 )

Tettigoniella sertigerula Jacobi, 1905 : p. 180 [original description]. Distribution: Peru and Bolivia.

Juliaca sertigerula ( Jacobi, 1905) : Young 1977: p. 448 [new combination], p. 469, fig. 384a, f, p [illustrations of the anterior dorsum and aedeagus]. Distribution: Ecuador, Peru, and Bolivia.

Length: male 4.8–5.1 mm (n = 3); female 5.1–5.2 mm (n = 2).

Head ( Figs. 14 View FIGURES 14–19 , 20 View FIGURES 20–27 ), in dorsal view, well produced anteriorly, triangular; median length of crown approximately 6/10 of interocular width and 4/10 of transocular width; anterior margin subacute, without carina at transition from crown to face. Ocelli located on imaginary line between anterior eye angles, each approximately equidistant between median line of crown and adjacent anterior eye angle. Crown without transverse concavity before ocelli; antennal ledge, in lateral view, with anterior margin vertical and straight. Face without distinct pubescence; frons slightly flattened medially, muscle impressions distinct; epistomal suture obsolete; clypeus, in lateral view, with profile continuing contour of frons.

Thorax ( Figs. 14 View FIGURES 14–19 , 20 View FIGURES 20–27 ) with pronotal width greater than transocular width of head; lateral margins of pronotum convergent anteriorly, posterior margin slightly concave; dorsolateral carina distinct, extending as far anteriorly as eye margin; disk without transverse rugae. Mesonotum with scutellum not striate. Forewing with membrane indistinct; bases of anteapical cells indistinct; four apical cells, base of fourth indistinct. Hind wing with vein R2+3 incomplete. Hind leg with length of first tarsomere greater than combined length of two more distal tarsomeres.

Male terminalia. Pygofer ( Fig. 15 View FIGURES 14–19 ), in lateral view, slightly produced posteriorly; posterior margin convex; disk with macrosetae on apical half; without processes. Subgenital plate ( Fig. 16 View FIGURES 14–19 ), in ventral view, with apical half strongly narrowed; in lateral view, extending posteriorly slightly beyond pygofer apex; with long uniseriate macrosetae, microsetae also present. Style ( Figs. 17–18 View FIGURES 14–19 ), in dorsal view, without preapical lobe; slightly narrowed preapically; apex truncate. Connective ( Figs. 17–18 View FIGURES 14–19 ), in dorsal view, Y-shaped, arms broad and strongly divergent; stalk short, not extending as far posteriorly as apex of style. Aedeagus ( Fig. 19 View FIGURES 14–19 ) symmetrical, without processes; shaft, in lateral view, with dorsal margin convex and ventral margin concave; apex truncate. Paraphyses ( Fig. 18 View FIGURES 14–19 ) symmetrical; in dorsal view, with stalk broad, articulated with apex of connective; rami very slender, shorter than stalk, with pair of basal projections directed basolaterally.

Female terminalia. Sternite VII ( Figs. 21–22 View FIGURES 20–27 ), in ventral view, well produced posteriorly, gradually narrowed towards apex; distal margin with small, median dentiform projection. Pygofer ( Fig. 21 View FIGURES 20–27 ), in lateral view, moderately produced posteriorly; posterior margin narrowly rounded; macrosetae distributed on posterior half and extending anteriorly along ventral margin. Second valvula ( Figs. 23–27 View FIGURES 20–27 ), in lateral view, straight; dorsal margin bearing about 20 continuous teeth; most teeth ( Figs. 24–26 View FIGURES 20–27 ) elongate, with basal portion projected dorsally and apical portion very low, flattened; apicalmost 3–4 teeth ( Fig. 27 View FIGURES 20–27 ) triangular; denticles distributed on teeth and on apical portion of blade (ventral dentate apical portion distinctly longer than dorsal portion, Fig. 27 View FIGURES 20–27 ); preapical prominence ( Fig. 27 View FIGURES 20–27 ) distinct; apex acute. Gonoplac (partially visible in Fig. 21 View FIGURES 20–27 ), in lateral view, with basal half narrow; apical half expanded, slightly narrowed towards apex; latter obtuse.

Color ( Figs. 14 View FIGURES 14–19 , 20 View FIGURES 20–27 , 28–30 View FIGURES 28–30 ). Dorsum dark brown to black with transverse stripes that may be complete or interrupted. Crown with transverse yellow, greenish-yellow or green stripe extending laterally over antennal ledges, or with pair of lateral spots. Pronotum with posterior transverse yellow, greenish-yellow or green stripe (sometimes covering most of disk, sometimes reduced to a few spots) extending laterally over lateral pronotal lobes. Forewing with two transcommissural yellow, greenish-yellow or green stripes, basal one extending from basal half of clavus (including apex of scutellum) to costal margin, apical one extending from distal portion of clavus to costal margin; distal third with yellow, greenish-yellow, green or bluish-white curved stripe extending from outer margin of first apical cell to costal margin; vitreous area located at costal margin between apical transcommissural stripe and curved distal stripe. Face dark brown to black; antennal ledge, posterior margin of gena, maxillary plate, inferior portions of lorum and clypeus, labrum, and labium yellow to brownish-yellow (these yellow to brownish-yellow areas are sometimes more extensive). Lateral and ventral portions of thorax mostly dark brown to black. Legs yellow to brownish-yellow; posterior coxa dark brown to black. Abdomen, in ventral view, dark brown to black; posterior margin of sternites and lateral and posterior margins of laterotergites yellow; subgenital plate yellowish-brown.

Taxonomic notes. Young (1977) illustrated only the anterior dorsum and aedeagus of J. sertigerula . The external morphology and color features of our specimens agree with the original description of Jacobi (1905). This colorful and variable species, whose (sometimes interrupted) stripes or spots may be yellow, greenish-yellow, green or bluish-white, can be distinguished by the following features ( Figs. 14 View FIGURES 14–19 , 20 View FIGURES 20–27 , 28–30 View FIGURES 28–30 ): (1) crown with transverse stripe extending laterally over antennal ledges, or with pair of lateral spots; (2) pronotum with posterior transverse stripe (sometimes covering most of disk, rarely reduced to a few spots) extending over lateral pronotal lobes; (3) forewing with two transcommissural stripes, a curved preapical stripe, and a vitreous area located at costal margin between distal transcommissural stripe and preapical curved stripe. In addition to the aforementioned color variation, the stripes (crown, pronotum, and forewing) also vary from narrow to broad ( Figs. 14 View FIGURES 14–19 , 20 View FIGURES 20–27 , 28–30 View FIGURES 28–30 ; see also images in Wilson et al. 2009, a site that shows intraspecific color variation in specimens from Chanchamayo, Junín, Peru).

Known distribution. Ecuador, Peru (Junín, Cusco, Madre de Dios), and Bolivia (La Paz) ( Jacobi 1905, Young 1977, McKamey 2007, Wilson et al. 2009).
