Labium extending to mesocoxae. Distiflagellomere with a sub-basal yellowish band. Membrane with a subapical pale spot. Metafemur darker on apical one-quarter. Processus gonopori widening towards apex.

Description (Fig. 25 B)

Total length 5.51.

Head: Dark reddish brown, clypeus paler, shiny; with abundant short recumbent and long erect setae dorsally. Head length 1.22, width 0.82. Postocular length 0.38. Eyes not surpassing the dorsal margin of head in lateral view. Ocelli placed at level of an imaginary line passing the posterior border of eyes. Interocular width 0.38, interocellar width 0.17. Labium pale brown, with erect setae; extending to mesocoxae. Labial segment lengths: I 0.72, II 0.91, III 0.72, and IV 0.24. Antennae: Scapus brown, pedicel and base of basiflagellomere pale brown, basiflagellomere distally reddish brown, distiflagellomere brown with a sub-basal yellowish band; all segments with abundant short recumbent setae and short semi-erect setae; basiflagellomere weakly clavate. Antennal lengths: scape 0.43, pedicel 1.03, basiflagellomere 0.96, and distiflagellomere 1.10. Length of pale band on distiflagellomere 0.34.

Thorax: Pronotum: pruinose, punctate, punctures larger on posterior lobe; anterior pronotal lobe reddish brown; collar paler, delimited posteriorly by a punctate sulcus, posterior lobe brown with irregular paler areas, each humeral angle with a pale spot; anterior and posterior lobes with short recumbent and erect setae, and long erect setae on anterior lobe. Collar length 0.08, anterior lobe length 0.51, posterior lobe length 0.48; anterior lobe width 0.83, posterior lobe width 1.30. Pleurae reddish brown, punctate, with short recumbent setae. Evaporative area extended. Scutellum reddish brown, pruinose, punctate, with short recumbent and long erect setae, as on anterior pronotal lobe. Hemelytra brown, with short recumbent setae, costal margin pale on proximal three-quarters, corium darker distally, with a subapical whitish spot and a pale spot internally (Fig. 25 B); membrane brown, veins paler, with a small subapical pale spot. Legs: Coxae, protrochanter, profemur, and meso- and metafemur distally brown, remainder of legs pale brown, tibiae darker apically (Fig. 26 B); with short recumbent and semi-erect setae, longer on profemur. Profemur with spines restricted to apical two-thirds. Protibia with minute denticles. Protibiae and mesofemur without spines.

Abdomen: Brown, with abundant short recumbent setae. Male genitalia: Pygophore (Fig. 27 E, F) rounded, elongate, with a straight posterior margin; slightly declivent posteriorly in lateral view; anterior margin of dorsal aperture rounded, inner projections subquadrangular. Parameres (Fig. 27 G, H) with outer projection not differentiated. Aedeagus: sclerotized lobes of vesica with a few spines; processus gonopori widening towards apex.

Distribution

Brazil, Ecuador, and Panama (Fig. 29).

Etymology

The specific ephitet ‘ apicalis ’, from the Latin apex, is an adjective, and refers to the distinct apical band on the metafemur.
