Description

MEASUREMENTS (mm). Total length. Males: 10.6–13.4 (n = 9), females: 10.8–13.5 (n = 10).

HEAD ( Fig. 1A View Fig ). In dorsal view, moderately produced anteriorly, anterior margin rounded, median length of crown approximately ⅓ of interocular width and ⅓ of transocular width. Frons ( Fig. 1C View Fig ), in frontal view, texture slightly granular, muscular impressions indistinct, epistomal suture complete. Clypeus ( Fig. 1C View Fig ), in frontal view, slightly pubescent apically. Pronotum ( Fig. 1A View Fig ), in dorsal view, with lateral margins slightly convergent anteriorly, posterior two-thirds of disk slightly transversely striated medially. Mesonotum ( Fig. 1A View Fig ) texture slightly granulated. Forewings ( Fig. 1A–B View Fig ) veins and membrane distinct, including inner apical cell and posterior third of remaining apical cells; bases of anteapical cells approximately aligned with claval apex. Remaining characteristics of external morphology as described for the genus by Young (1977: 747).

COLORATION. Crown ( Fig. 1A–B View Fig ) yellow. Frons ( Fig. 1C View Fig ) yellow, with a brown horseshoe-shaped macula. Clypeus ( Fig. 1C View Fig ) yellow, with a longitudinal brown stripe medially, enlarging in apex. Lorum and gena ( Fig. 1C View Fig ) yellow. Pronotum ( Fig. 1A View Fig ) yellow, with a browned stripe medially and posterior margin brown. Mesonotum, meso and metasternum ( Fig. 1B–C View Fig ) yellow. Forewing ( Fig. 1A–B View Fig ) red, with longitudinal yellow or whitish longitudinal stripes, membrane darkened. Legs ( Fig. 1B–C View Fig ) yellow with distal portions darkened. Abdomen ( Fig. 2A–B View Fig ) yellow, with lateral margins blackened.

MALE GENITALIA. Pygofer ( Fig. 1D View Fig ), in lateral view, strongly produced posteriorly, dorsal, and ventral margins narrowed after basal third, posterior margin broadly rounded, macrosetae distributed along the posterior thirds of disc; in dorsal view, apex directed inwards. Valve ( Fig. 1E View Fig ), in ventral view, narrow, lateral margins acute apically, ventral margin slightly rounded. Subgenital plate ( Fig. 1D–E View Fig ), in ventral view, triangular, broadened at base, narrowing gradually towards apex, inner margin rectilinear, outer margin with a uniseriate row of macrosetae; in lateral view, slightly surpassing pygofer apex, dorsal margin with multiseriate row of long microsetae. Style ( Fig. 1F View Fig ), in dorsal view, very elongate, extending posteriorly much beyond apex of connective, apical portion curved outwards, outer margin bearing microsetae, apex rounded. Connective ( Fig. 1F View Fig ), in dorsal view, V-shaped, arms, and stalk short, with a median keel. Aedeagus ( Fig. 1G–H View Fig ), in lateral view, shaft broadened apically, dorsal margin slightly curved, apex truncated; in dorsal view, apex opened medially as the gonopore exit. Aedeagal atrium well developed, forming a sheath-like structure with apical portion curved anteriorly, reaching shaft’s apex, with two pairs of acute processes, one elongate basidorsal, with an acute and curved ventrally apex, trespassing much far as shaft’s apex; second short and acute, located preapically; in ventral view, preapical short processes subparallel, and basidorsal processes apical portions convergent.

FEMALE GENITALIA. Pygofer ( Fig. 2B View Fig ), in lateral view moderately produced posteriorly, posterior margin triangular, macrosetae along ventral and posterior margins. Abdominal sternite VII ( Fig. 2A–C View Fig ) wider than long, posterior margin slightly emarginated medially; posterolateral corners slightly directed outwards. Valvifer I ( Fig. 2D View Fig ), in lateral view, rounded. Valvula I ( Fig. 2D–E View Fig ), in lateral view, blade narrowed apically, apex acute; dorsal sculptured area strigate, extending from basal portion to apex, ventral sculpted area strigate, restricted to apical portions. Valvula II ( Fig. 2F–H View Fig ), in lateral view, slightly expanded beyond basal curvature, narrowing gradually towards apex; without preapical prominence; apex rounded; dorsal margin with 40 continuous teeth, irregular shaped after basal curvature, robust and subtriangular at basal and median portions and small and trapezoid in apical portion, all bearing denticles. Gonoplac ( Fig. 2I–J View Fig ), in lateral view, with basal half narrow, bearing denticuli in ventral margin, apical half expanded; apex rounded, with apical surface bearing denticuli and few macrosetae in ventroposterior margin.

Remarks

Ruppeliana coronata and R. nigripes were suggested by Young (1977) to be possible synonyms. However, they can be distinguished by several morphological characteristics. The forewing coloration is reddish at R. coronata and brown in R. nigripes . In dorsal view, the pygofer apices are directed inwards in R. coronata ( Fig. 15A View Fig ), whereas they are subparallel in R. nigripes ( Fig. 15B View Fig ). Additionally, the subgenital plate reaches or surpasses pygofer apex in R. coronata , while in R. nigripes , it does not extend beyond pygofer apical portion.
