Measurements male / female.

Head length: 0.895 / 0.88; head width: 1.88 / 1.99; pronotum length: 1.63 / 1.56; pronotum width: 2.96 / 3.0; tegmen length: 8.14 / 8.4; tegmen width: 2.50 / 2.56; total length: 10.00 / 10.04 (in mm)

Diagnosis.

Tegmina yellowish, with longitudinal brownish bands extending until the apical third; dorsal margin of subgenital plate straight or with rounded elevation.

Redescription.

Head brownish to yellowish, vertex subretangular with a slightly marked median carina, ocelli closer to each other than to eyes, separated by about one diameter from each other; tylus quadrangular, median carina indistinct (Fig. 8 A View Figure 8 ); antenna brownish, pedicel sparsely setose, basal body of flagellum subcylindrical with a single and short arista shorter than the pedicel length. Postclypeus yellowish, inflated, with convex profile, longitudinal brownish carina present, lateral grooves slightly marked (Fig. 8 B, C View Figure 8 ); rostrum with second segment yellowish and third segment brownish, reaching the base of mesocoxae. Pronotum brownish, hexagonal, with muscular insertions slightly apparent, median carina indistinct; anterior and anterolateral margins straight; posterolateral with slight sinuosity and posterior margin medially grooved, humeral angles acute; scutellum brownish, with slight central concavity and slightly marked horizontal grooves. Tegmina (Fig. 8 A, B View Figure 8 ) yellowish, narrow, with longitudinal brownish bands united near the base of tegmina and extending until its apical third, veins M and Cu 1 united at base, veins A 1 distinct and A 2 indistinct, apical reticulation undeveloped, slightly visible venation. Hindwings hyaline, with brownish venation, Cu 1 thickened at the base, hamuli with three to five spines. Legs yellowish, metathoracic femur with a small apical black spine; tibia with two lateral spines, basal one smaller than the ones located at apical crown, which has 12–13 spines arranged in two rows; basitarsus with two rows of spines covered by long setae; subungueal process present. — MALE: Genitalia: Pygofer (Fig. 8 D, E View Figure 8 ) with one finger-like process between anal tube and subgenital plate; subgenital plate long with acute, spine-like apex (Fig. 8 D – G View Figure 8 ), apical third slightly inclined towards dorsal margin (lateral view); dorsal margin of subgenital plate straight (Fig. 8 D View Figure 8 ) or with a rounded elevation (Fig. 8 E View Figure 8 ) covered with small tooth-like spines. Paramere (Fig. 8 H, I View Figure 8 ) subrectangular with a subtriangular apex; dorsal margin rounded and slightly developed (Fig. 8 H View Figure 8 ) or mountain-shaped (Fig. 8 I View Figure 8 ), one subapical hook-like spine directed outwards and forward. Aedeagus (Fig. 8 J – M View Figure 8 ) subcylindrical, narrowing towards apex, with a pair of straight dorsal processes, shorter than half length of shaft (Fig. 8 K View Figure 8 ) or with almost the same length of half of the shaft (Fig. 8 J View Figure 8 ), presenting intermediate morphs as showed in Figure 3 View Figure 3 , inserted between median and apical third of aedeagus. — FEMALE: Morphologically similar to male. First valvula of ovipositor long (Fig. 8 N, O View Figure 8 ), with acute apex, basal process rounded and undeveloped, directed backwards; second valvula long (Fig. 8 P View Figure 8 ) with rounded apex and dorsal margin covered by inconspicuous teeth in apical third; third valvula wide, with rounded apex, covered ventrally by long setae.

Remarks.

This species presents a high variation in the male genitalia, as shown in Figure 3 View Figure 3 : the dorsal margin of the subgenital plate can range from straight to rounded; there are differences in the degree of elevation of the dorsal margin of paramere, and variability in the length of the dorsal processes of the aedeagus.
