Diagnosis.
Antennal segment I yellow (Fig. 3D View Figure 3 ), segment III with basal half pale yellow, distal half darker; femora yellow; level of vertex attaining dorsal margin of eyes (Fig. 2D View Figure 2 ); labium extending at least to metacoxae and segment I deeply concave ventrally and narrowing distally; calli small, not attaining lateral pronotal margins; embolium longer than abdomen; internal margin of cell convex; without sexual dimorphism on internal margin and length of cuneus (Fig. 1D View Figure 1 ); dorsal wall of genital capsule well developed, with two tiny medial and sclerotized teeth (Figs 5F View Figure 5 , 7E, F View Figure 7 ); left process of subgenital plate C-shaped in dorsal view, divided into two broad branches; right process ending in many asymmetrical teeth (Fig. 7E, F View Figure 7 ); left paramere smaller than the right paramere; right paramere curved, with apex expanded dorsoventrally (Fig. 9E View Figure 9 ); and aedeagus less than or as long as the genital capsule.
Description.
Macropterous male. Coloration. Head yellow. Labium yellow. Eyes black with silver spots. Antennal segment I yellow; II, dark brown; III, basal half whitish, more than distal half brown. Thorax: collar, pronotum, scutellum and pleural area yellow. Hemelytron, legs and abdomen yellow, tarsi whitish.
Surface. Antennal segment I-II with recumbent setae, and a few semierect setae, more abundant on segment II. Antennal segments III with semierect setae and a few erect setae. Pleural area and abdomen with longer and more disperse setae than dorsum. Coxae, trochanters, femora, and tarsi with semierect setae. Tibiae with abundant recumbent setae.
Structure. Head: level of vertex attaining dorsal margin of eyes (Fig. 2D View Figure 2 ). Maxillary plates long and thin. Labium just beyond metacoxae; segment I, deeply concave ventrally and narrowing distally; II, thin and long; III-IV, wider and short. Antennal segment II more than 2 times as long as antennal segment I. Thorax: posterior pronotal margin 2 times as wide as pronotum length. Calli small, not attaining lateral pronotal margins. Pronotal width across calli more than half of posterior margin width. Hemelytron: embolium straight, bent upwards from its anterior end to more than anterior third; longer than abdomen. Claval commissure longer than scutellum and half pronotum length combined. Internal margin of cuneus concave (Fig. 1D View Figure 1 ). Male genitalia: genital capsule more than one third abdomen length. Dorsal wall with two tiny, medial, sclerotized teeth directed upwards; the left tooth larger than the right (Figs 5E, F View Figure 5 , 7E, F View Figure 7 ). Subgenital plate with two large processes at the level of paramere insertions. Left process, shorter than right process, flat, broad basally and forked. Right process longer, thinner, extremely broad basally with small external tooth, C-shaped, apex with several asymmetrical teeth (Fig. 7E, F View Figure 7 ). Left paramere (Fig. 8E, F View Figure 8 ) smaller and broader than right paramere, with a blunt dorsal projection, apical process with an internal, triangular, tooth, apex flat, thin and sclerotized. Right paramere (Fig. 9E, F View Figure 9 ) curved; body wide basally, narrowed distally; apical process expanded dorsoventrally, dorsal expansion blunt, with ventral expansion pointed. Aedeagus (Fig. 10C View Figure 10 ) phallotheca sclerotized on left side, with a dorsal stripe and a ventral oblique stripe sclerotized; endosoma sclerotized.
Measurements: Body length to apex of membrane 4.46; body length to apex of cuneus 3.95; body width 1.94. Head: width 1.08; interocular distance 0.56, 1.22 times as wide as head length and 1.47 times as wide as antennal segment I length. Labium: segment I length 0.52; II, 0.62; III, 0.17; IV, 0.18. Antenna: segment I length 0.38; II, 0.91; III, not measured; IV, absent. Pronotum: length 0.71; anterior width 0.80; posterior width 1.46. Scutellum: length 0.50; width 0.74. Cuneus: length 0.98; anterior width 0.76. Cell 2.78 times as long as wide.
Macropterous female. Similar to males in size, coloration, surface, and structure. Antennal segment II basally yellow, distally dark brown; IV, brown.
Structure. Antennal segment II more than 2.5 times as long as antennal segment I. Thorax: posterior pronotal margin more than twice as wide as pronotum length. Pronotal width across calli less than half of posterior margin width. Hemelytron: embolium bent upwards from its anterior end to a half or more than a half its length. Medial fracture attaining half corium length. Claval commissure equal to or longer than scutellum and half pronotal length combined. Cuneus not bent downwards.
Measurements (n: 4): Body length to apex of membrane 4.28-4.79; body length to apex of cuneus 3.7-4.23; body width 1.97-2.09. Head: width 1.07-1.10; interocular distance 0.54-0.59, 1.20-1.34 times as wide as head length and 1.50-1.64 times as wide as antennal segment I length. Labium: segment I length 0.48-0.54; II, 0.49-0.65; III, 0.18-0.19; IV, 0.18. Antenna: segment I length 0.36-0.37; II, 0.92-1.0; III, 0.44-0.46; IV, 0.58-0.62. Pronotum: length 0.74-0.80; anterior width 0.77-0.82; posterior width 1.54-1.58. Scutellum: length 0.49-0.55; width 0.72-0.77. Cuneus: length 0.98-1.09; anterior width 0.74-0.78. Cell 2.34-2.8 times as long as wide.
