Treatment

HERAEUS PENAI View in CoL SP. NOV.

( FIGS 29 View Figure 29 , 30H View Figure 30 , 36G View Figure 36 , 39D View Figure 39 , 40M–P View Figure 40 )

Diagnosis

Labium almost extending to metacoxae. Distiflagellomere with a narrow pale band sub-basally. Membrane brown, with veins paler. Metafemur with a narrow subapical brown band.

In addition to Heraeus penai sp. nov., only H. pallidinervis sp. nov. and H. loja sp. nov. have a narrow pale band on distiflagellomere, occupying about one-quarter of segment length, and a long labium extending to metacoxae. The male genitalic characters, however, will differentiate these species.

Description ( Fig. 36G View Figure 36 )

Total length 5.61.

Head: Brown, shiny, coriaceous, with abundant short recumbent and sparse long erect setae. Head length 1.22, width 0.84. Postocular length 0.43. Eyes not surpassing the dorsal margin of head in lateral view. Ocelli at level of an imaginary line passing the posterior border of eyes. Interocular width 0.43, interocellar width 0.26. Labium pale brown with erect setae, almost extending to metacoxae. Labial segment lengths: I 0.83, II 0.96, III 0.80, and IV 0.32. Antennae pale brown, except apex of scapus, pedicel, and basiflagellomere; distiflagellomere darker, with a narrow pale band subbasally; all segments with abundant short semi-erect and sparse longer erect setae. Antennal lengths: scape 0.46, pedicel 0.96, basiflagellomere 0.86, and distiflagellomere 0.98. Length of pale band on distiflagellomere 0.24.

Thorax: Anterior pronotal lobe brown, collar and posterior lobe paler, with irregular paler areas, humeral angles with a whitish spot; collar delimited posteriorly by a punctuate sulcus; punctate, punctures larger on posterior lobe; anterior and posterior lobes with short recumbent and erect setae, longer erect setae on anterior lobe. Collar length 0.07, anterior lobe length 0.53, posterior lobe length 0.50; anterior lobe width 0.90, posterior lobe width 1.39. Pleurae brown, acetabular areas paler, punctate, with short recumbent setae. Evaporative area extended. Scutellum brown, with a darker longitudinal median stripe, pruinose, punctate, with short recumbent and long erect setae, as for anterior pronotal lobe. Hemelytra brown, costal margin pale on proximal three-quarters, apical half of corium darker, with a subapical whitish spot and a small pale rounded spot internally ( Fig. 36G View Figure 36 ); setae short and semierect; membrane brown with pale areas, veins paler. Legs: Coxae, protrochanter, profemur, except distally, and a subapical narrow band on metafemur brown, re- mainder of legs pale brown; mesofemur with a narrow band subapically and apex of tibiae darker ( Fig. 39D View Figure 39 ); setae abundant and semi-erect, longest on profemur. Profemur with spines restricted to apical two-thirds.

Abdomen: Brown, with abundant short recumbent setae. Male genitalia: Pygophore ( Fig. 40M, N View Figure 40 ) rounded, anterior margin of dorsal aperture slightly rounded, inner projections subquadrangular; declivent posteriorly in lateral view. Outer projection of parameres not developed ( Fig. 40O, P View Figure 40 ). Aedeagus ( Fig. 30H View Figure 30 ): conjunctiva with spines laterally beneath the ejaculatory reservoir; vesica with two pairs of lobes, the anterior lobe short, unsclerotized, and with many spines, and the posterior lobe larger and sclerotized, with a few spines distally; processus gonopori long and slender.

Distribution

Argentina, Bolivia, and Paraguay ( Fig. 29 View Figure 29 ).

Etymology

This species is named after the late Luiz E. Peña, who collected the holotype and some of the paratypes.
