Description

Description. MALE HOLOTYPE. Body length (from apex of head to apex of hemelytra): 14.48; greatest vertex width: 1.45; synthlipsis: 0.95; eye width: 1.90; head length: 1.35; greatest head width: 4.60; pronotum length: 1.50; greatest pronotum width: 5.45; scutellum length: 4.05; scutellum width: 4.60. Color. Setae yellow (Fig. 25). Head yellow. Vertex with two brown triangles. Labrum, triangle at the base of second rostral segment, line along third rostral segment length, and fourth segment, brown. Pronotum yellow. Scutellum brown centrally (Fig. 24). Legs yellow; patch of pubescence of foretibiae and - tarsi brown. Anterior half of hemelytra yellow, posterior half brown. Hind wings hyaline mixed with brown (Fig. 27). Abdominal terga almost entirely brown, with borders yellowish; abdominal sterna brown (Fig. 25). External morphology. Head with greatest width 3.4 times its median length, and 3.2 times vertex width. Vertex 1.5 times synthlipsis. Eye width 2.0 times synthlipsis. Pronotum with greatest width 3.6 times its median length and 1.2 times head greatest width, median length 1.1 times median length of head; posterior margin of pronotum concave medially (Fig. 24). Scutellum with greatest width 1.1 times its median length; median length almost 4 times pronotum median length; punctations in longitudinal strip, with punctures rounded to elongated, shallow (Fig. 26). Apical half of ventral surface of middle femur densely setose, setae long and thin (Figs. 28, 30); lateral margin with 17 dark pegs (Fig. 30); anteapical pointed protuberance well developed, triangular, with lateral margins straight (Fig. 29). Hemelytra with nodal furrow straight, curved anterad, shorter than the distance between its tip and membranal suture. Margins of metaxyphus convex, tapering to apex; apex rounded; its surface with two strips of setae (Fig. 31). Genitalia. Posterior part of male genital capsule ending in acute angle without process. Right paramere with dorsal margin sinuous; anteriorly emarginate, dorsal and ventrally, making it somewhat projected; rounded posteriorly; setae distributed throughout median region (Fig. 32). Left paramere angled anteriorly, with a slight projection on dorsal margin; rounded posteriorly; setae distributed on dorsal region (Fig. 33). FEMALE PARATYPES (n = 3). Body length (from apex of head to apex of hemelytra): 13.0 – 14.1; greatest vertex width: 1.3 – 1.5; synthlipsis: 0.8 – 0.96; eye width: 1.6 – 1.8; head length: 1.3 – 1.5; greatest head width: 4.3 - 4.5; pronotum length: 1.6; greatest pronotum width: 4.6 – 5.1; scutellum length: 3.5 – 4.1; scutellum width: 4.0 – 4.5. Color. Similar to holotype, except frons yellowish laterally; median region of frons and tylus brownish. Ventral surface of foretibia and tarsus brown (Fig. 35). Hemelytra brownish, with costal region yellowish; opaque zone of membranal lobe brown, except basal lobe and apical lobe hyaline stained with brown (Fig. 34). External morphology. Differs from holotype by head greatest width 2.9 – 3.5 times its median length, 2.9 – 3.3 times vertex width. Vertex 1.5 – 1.6 times synthlipsis. Pronotum with greatest width 2.8 – 3.2 times its median length and slightly larger than greatest width of head; median length 1.1 – 1.2 times median length of head (Fig. 34). Ventral surface of female middle femur with short and scarce pubescence (Fig. 35). Abdominal sternum VII broad, with apex square, truncate (Fig. 36).
