Description. Body length 7.79–9.87 (mean = 8.56). Head length 1.17–1.53 (mean = 1.35), width 0.73–0.83 (mean = 0.77). Head tuberculated, light brown with sparse light brown setae ( Fig. 2A View FIGURE 2. A – L ). Antennal length 5.70 (last segment lost). Antennal tubercle with scattered setiferous tubercle at base. Antenna light brown, segment I with tubercle at base, setose. Width of eyes 0.17–0.20 (mean = 0.19), interocular space 0.37–0.43 (mean = 0.40). Gula dark brown. Genae protruded, light brown tinged with yellow. Rostrum length 1.20 1.42 (mean = 1.30), ratio of segments' lengths ca. 1: 1.44: 1.16. Rostrum light brown, darker distally and at intersegmental regions, with setae longest ventrally on segment I and shortest dorsally on segments II and III. Neck with setose tubercles. Pronotum length 2.03–2.50 (mean = 2.22), width 1.03–1.37 (mean = 1.20). Anterior lobe light brown with long setose tubercles, brown median sulcus evident. Posterior lobe granulated, light brown. Posterior edge invaginated. Two spines on humeral angles. Sterna setose. Scutellum with two long spines ( Fig. 2B View FIGURE 2. A – L ).

Fore legs light brown, femur with setose tubercles, and tarsi brown ( Fig. 2C View FIGURE 2. A – L ). Median and hind legs light brown with sparse thin setae. No differences between width of femora and tibia, tibia with more abundant thin setae, tarsi brown. Stridulatory sulcus light brown, with setose tubercles laterally ( Fig. 2D View FIGURE 2. A – L ). Hemelytra length 4.56–5.76 (mean = 5.03), color light brown. Abdomen length 2.72–5.70 (mean = 4.57), width 1.20–2.43 (mean = 1.60). Abdomen not visible dorsally, with two posterolateral projections and protruded spiracles ( Fig. 2E View FIGURE 2. A – L ). Connexivum light brown. Urotergites light brown, with sparse short setae.

Male: pygophore with granulations and setae, distally with two rounded setose projections ( Fig. 2F View FIGURE 2. A – L ). Parameres elongate with long external setae ( Fig. 2G View FIGURE 2. A – L ). Base of pygophore median process thick, apical hook rounded ( Fig. 2H View FIGURE 2. A – L ). Phallus ( Fig. 2I View FIGURE 2. A – L ), articulatory apparatus ( Fig. 2J View FIGURE 2. A – L ).

Female: gonocoxite VIII sub rectangular, with abundant setae ( Fig. 2K View FIGURE 2. A – L ), laterally expanded, relation between maximal width of gonocoxite and maximal width of gonapophysis 2.5: 1. Gonocoxite IX sub quadrangular with abundant long setae distally ( Fig. 2 L View FIGURE 2. A – L ).

Geographic distribution ( Fig. 4 View FIGURE 4 A): COLOMBIA, GUATEMALA, MEXICO, PAN AMA, PUERTO RICO, and VENEZUELA.

Observations: First records for Colombia, Panama, and Venezuela, new locality records for Guatemala and Mexico. This species differs from the others by the conspicuous spinose tegument and the abdomen with two posterolateral projections and protruded spiracles.
