Head: light brown except laterally neck brown; anteocular and postocular region, gena, antenniferous tubercles, labium, clypeus and jugum brown or dark brown in some specimens, each ocelli tubercle brown; eyes surpassing inferior margins of head in males; antenna I light brown basally in males, darker apically, light brown basally in females, in middle brown, close to apex light brown and brown apically; II basally to middle light brown, and brown toward apex; III brown, thickened at base and reduced gradually toward apex in males; rostrum I and II light brown or brown in some specimens; III brown or dark brown in some specimens. Pronotum: anterior lobe light brown medially and brown or dark brown laterally; anterolateral angles brown or dark brown; collar light brown; males with two narrow lines of hairs placed next to longitudinal sulcus, beginning in anterior margin and reaching posterior lobe; submedian carina reaching less than half of posterior lobe; posterior lobe light brown with a very narrow brown middle longitudinal line beginning in anterior margin and ending in posterior margin; two brown inverted “V” coloration patterns, each one reaching humeral and discal spines (Fig. 1 B) (female specimen light brown medially, humeral angles and part of disc dark brown). Scutellum: principal body light brown or yellowish in some specimens; posterior process pale, brown or yellowish in some specimens, acuminate, short and rounded. Pleura: light brown or brown in some specimens with a brown or dark brown irregular broad lateral line covering pro-, meso-, and metapleuron near inferior margin; prosterna brown or dark brown except stridulatory sulcus, this light brown; mesosterna and metasterna brown, light brown or yellowish in some specimens. Legs: coxae light brown with a brown dorsal spot basally; trochanters light brown; femora light brown, apex darker, with four brown lines: two dorsally and two ventrally covering from base to apex; fore tibiae light brown with four brown bands: basally, close to base, medially and apically; tarsus brown. Abdomen: connexival segments: light brown; unarmed; urosternites light brown with an irregular brown broad lateral band pattern near connexivum in segments II–VII. Macropterous form: brown. Hemelytra: corium and clavus light brown; hemelytron in males 1.60 mm longer than abdomen, in female as long as abdomen; membrane hyaline-brownish. Male genitalia: pygophore subquadrangular, slightly longer than wide, median process (mp) developed, short, acute, lateral median process (lmp) rounded, much longer than median process with abundant long hairs (Fig. 8 A), parameres very long surpassing apex of abdomen (Fig. 5 B), thick, curved, pigmented with brown externally, abundant long hairs all around parameres beginning in middle and directed distally (Fig. 9 A). Phallus: articulatory apparatus (aap) long, oval and narrow, basal plate bridge (bpb) short and thin, pedicel (ped) very wide (Fig. 10 A). Female genitalia: posterior view: as in (Fig. 11 B). Gonocoxite VIII (gcx8): sparse thin hairs with a brown semicircular spot near external margin (Fig. 12 B), anterior fibula slightly (af) subquadrangular, widened at base (Fig. 12 B). Gonapophysis VIII (gnp8): without hairs (Fig. 12 B). Gonocoxite IX: ventrally with abundant thin hairs, not wide basally (Fig. 13 B).
