Redescription ( Fig. 43 View Figure 43 D)

Paralectotype ♂.

Head: Porrect, brown, shiny, coriaceous, with short recumbent, long semi-erect, and erect setae dorsally; elongate, convex dorsally, preocular length longer than postocular length. Eyes relatively small, not surpassing the dorsal margin of head in lateral view. Ocelli small, posterior to an imaginary line passing the posterior border of eyes. Labium pale brown, with short erect setae; almost extending to mesocoxae. Antennae brown, apex of basiflagellomere reddish brown, distiflagellomere with a wide pale band sub-basally; all segments with abundant short recumbent setae.

Thorax: Pronotum pale brown to brown, pruinose, anterior lobe subshiny, collar well delimited posteriorly by a sulcus and with a row of punctures, anterior and posterior lobes with short recumbent and long erect setae. Posterior pronotal lobe and sulci punctate. Maximum width of anterior pronotal lobe behind middle. Pleurae brown. Scutellum brown, dull, basal half darker, punctate, with short recumbent and long erect setae. Hemelytra: clavus brown with a pale stripe between outer and inner row of punctures on basal half; corium with lateral margins slightly concave, smooth, general colour brown, costal margin pale on proximal three-quarters, with a large subapical pale brown spot ( Fig. 43 View Figure 43 D); with short recumbent and semierect setae. Membrane brown, veins concolourous, with a diffuse apical pale spot. Legs: Brown, meso- and metatrochanter and meso- and metafemur pale brown basally ( Fig. 44 View Figure 44 D); with abundant erect setae, longer on profemur. Mesofemur with long erect setae ventrally only; metafemur with long erect setae ventrally and restricted to apical third dorsally. Profemur with two rows of spines on apical half. Protibia without spines. Tibiae with spiniform setae.

Abdomen: Brown, with abundant short recumbent setae. Male genitalia: Pygophore ( Fig. 45 View Figure 45 M, N) rounded, anterior margin of dorsal aperture almost straight, inner projections subrectangular, more produced posteriorly. Parameres with outer projection bearing long setae and a prominence basally on inner projection ( Fig. 45 View Figure 45 O, P). Aedeagus ( Fig. 46 View Figure 46 B) unspined, vesica with two weakly sclerotized lobes, wings of the ejaculatory reservoir large and bent apically, apex directed backwards; processus gonopori long and slender.

Distribution

Guatemala, Mexico, and USA; Honduras (NEW RECORD) ( Fig. 49 View Figure 49 ).

Variability observed

Distant described this species based on specimens from San Geronimo, Capetillo, and Las Mercedes in Guatemala; Scudder (1967) designated a female from Las Merdeces as the lectotype. Some specimens differ from the paralectotype by the smaller size, the longer labium extending to mesocoxae, the presence of long erect setae on posterior pronotal lobe, the generally darker colouration, and the more contrasting colour pattern of the hemelytra. In some specimens, the darker basal half of the scutellum is not quite evident and males generally have a more strongly globose anterior pronotal lobe than females.
