Labium pale brown, dorsal margin of segment II and apex of segment IV dark brown, extending to mesocoxae. Length of labial segments: I 2.30, II 2.16, III 1.88, IV 1.78.
Thorax
Pronotum (Fig. 16A): dark brown with short decumbent yellowish setae, and longer and darker erect setae all over the surface; anterior lobe and calli smooth, unarmed; posterior lobe punctate with short, rounded, smooth and shiny tubercles partially anastomosed on posterior region; anterolateral margins straight and with sparse small tubercles; humeral angles tuberculated, slightly expanded and not elevated, ending in a subacute protuberance directed backwards; humeral distance slightly larger than width of abdomen; posterolateral margins tuberculated, triangular processes short. Width of humeral angles 9.50. Scutellum: wider than long, with conspicuous transversal rugosities, and sparse yellowish decumbent and erect setae; base elevated with two barely apparent small median tubercles; apex pale brown, incrassate. Length of scutellum 3.43, width 3.52. Thoracic pleurae: pale brown, with sparse decumbent yellowish setae; metathoracic gland auricle and evaporatory area yellowish with rugosities, anterior lobe of auricle with a central brown macula, rounded, posterior lobe elongated (Fig. 16B); supracoxal area of metapleura not incrassate. Thoracic sterna: brown, with abundant erect yellowish setae; mesosternal anterior projection paler.
Hemelytra. Clavus and corium pale brown, with punctures along and next to veins and in the center of the cells, with sparse short decumbent yellowish setae on punctures, veins concolor; costal margin unarmed; membrane glabrous, veins paler. Length of hemelytra 20.12.
