description: HERAEUS PALLIDINERVIS SP. NOV.  (FIGS 35, 36F, 39C, 40I–L)  
 Diagnosis   
Labium extending to metacoxae. Distiflagellomere with a narrow pale band sub-basally. Membrane brown, with veins paler and without an apical corial spot. Meso- and metafemur with a wide subapical brown band.  
 In addition to Heraeus pallidinervis sp. nov., H. penai sp. nov. and H. loja sp. nov. have a narrow pale band on the distiflagellomere, occupying about onequarter of the segment length, and a long labium extending to the metacoxae; but H. pallidinervis sp. nov. has a broader pale band on the metafemur than the other two species. The male genitalic characters also differentiate these species.   
 Description (Fig. 36F)   
Total length 4.80.  
 Head: Convex dorsally, dark brown, shiny, coriaceous, with short recumbent and long erect setae. Head length 1.15, width 0.77, postocular length 0.40. Eyes with setae between ommatidea; not surpassing dorsal margin of head in lateral view. Ocelli small, at level of an imaginary line passing the posterior border of eyes. Interocular width 0.45, interocellar width 0.24. Labium pale brown, with erect setae; extending to metacoxae. Labial segment lengths: I 0.77, II 0.80, III 0.72, and IV 0.34. Antennae pale brown, scapus, apical region of pedicel and basiflagellomere darker, distiflagellomere brown with a narrow pale band sub-basally; all segments with abundant short recumbent and sparse semierect setae. Antennal lengths: scape 0.43, pedicel 0.88, basiflagellomere 0.75, and distiflagellomere 0.99. Length of pale band on distiflagellomere 0.27.   
 Thorax: Pronotum pruinose; dark brown, except collar and four longitudinal stripes on posterior lobe paler, humeral angles with a pale spot; punctate, more conspicuous on posterior lobe; anterior lobe with short recumbent and long erect setae. Collar length 0.08, anterior lobe length 0.48, posterior lobe length 0.32; anterior lobe width 0.80, posterior lobe width 1.18. Pleurae dark brown, punctate, with short recumbent setae. Evaporative area extended. Scutellum dark brown, pruinose, punctate, with short recumbent and long erect setae. Hemelytra pruinose, with short recumbent setae, costal margin pale on proximal three-quarters, with a subapical corial spot, colouration pattern as Figure 36 (F). Membrane brown with pale spots between veins, veins pale. Legs: Coxae and protrochanter brown; profemur brown, except apical region paler; meso- and metafemur yellowish with a wide subapical brown band; tibiae and tarsi pale brown, tibiae darker at apex (Fig. 39C); setae short and semi-erect. Profemur with two rows of spines on apical two-thirds.   
 Abdomen: Dark brown, with abundant short recumbent setae. Pygophore (Fig. 40I, J) rounded, slightly quadrangular, anterior margin of dorsal aperture rounded, inner projections elongate, more produced posteriorly; strongly declivent posteriorly in lateral view. Parameres: Figure 40 (K, L). Aedeagus: spinose, spines relatively larger than in most species; conjunctiva with spines laterally beneath the ejaculatory reservoir; vesica with spines laterally and two pairs of lobes, the posterior pair sclerotized and without spines, and the anterior pair with spines; processus gonopori long and slender.   
 Distribution   
Bolivia and Brazil (Fig. 35).  
 Etymology   
 The specific epithet ‘ pallidinervis ’ is an adjective referring to the contrasting pale colouration of the veins on a darker brown membrane.
