description: HERAEUS BAHIENSIS SP. NOV.  (FIGS 25C, 26C, 27I–L, 29, 30A)  
 Diagnosis   
Distiflagellomere with a sub-basal whitish band. Labium extending to mesocoxae. Membrane brown with an apical pale spot. Meso- and metafemur with a subapical brown band. Pygophore with the apex pointed dorsally in lateral view.  
 The diagnostic characters relate this new species to H. nicaraguensis sp. nov., but they can be distinguished by the paler general colouration of H. bahiensis sp. nov., with the head dark reddish brown and the posterior pronotal lobe brown with diffuse longitudinal stripes, whereas in H. nicaraguensis sp. nov. the head is blackish and the posterior pronotal lobe is dark brown with four longitudinal pale stripes.   
 Description (Fig. 25C)   
Total length 5.61.  
 Head: Brown, shiny, with short recumbent and long erect setae dorsally. Head length 1.12, width 0.88. Postocular length 0.37. 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 0.42, interocellar width 0.24. Labium pale brown, with erect setae; extending to mesocoxae. Labial segment lengths: I 0.80, II 0.85, III 0.66, and IV 0.35. Antennae pale brown, scape externally, basiflagellomere distally, and distiflagellomere darker, distiflagellomere with a sub-basal whitish band occupying about one-third of segment length; all segments with abundant short recumbent and sparse short erect setae. Antennal lengths: scape 0.43, pedicel 1.04, basiflagellomere 0.91, and distiflagellomere 0.96. Length of pale band on distiflagellomere 0.37.   
 Thorax: Anterior pronotal lobe brown, posterior lobe paler with mottled pale areas, humeral angles yellowish; collar punctate, delimited posteriorly by a punctate sulcus; anterior and posterior lobes with short recumbent setae, with longer erect setae on anterior lobe. Pronotum pruinose, punctate, punctures larger on posterior lobe. Collar length 0.08, anterior lobe length 0.48, posterior lobe length 0.48; anterior lobe width 0.90, posterior lobe width 1.44. Pleurae brown, acetabular areas paler, punctate, with short recumbent setae. Evaporative area extended. Scutellum brown, with a longitudinal median dark stripe, apex paler, pruinose, punctate, with short recumbent and long erect setae, as on anterior pronotal lobe. Hemelytra pale brown, irregularly pigmented, with short recumbent setae. Costal margin pale on proximal three-quarters, apex of corium darker with a subapical whitish spot and an inner small pale spot; membrane brown, veins paler with an apical pale spot (Fig. 25C). Legs: Coxae, protrochanter, profemur, except distally, and a subapical band on meso- and metafemur brown; remainder of legs pale brown, apex of tibiae, tarsi, and pretarsi darker (Fig. 26C); with semi-erect setae longer on profemur. Profemur with spines restricted to apical two-thirds.   
 Abdomen: Brown, with abundant short recumbent setae. Male genitalia: Pygophore (Fig. 27I, J) rounded, anterior margin of dorsal aperture slightly rounded, apex with a small protuberance; declivent posteriorly in lateral view. Inner projections elongate, more pronounced posteriorly. Parameres: Figure 27 (K, L). Aedeagus (Fig. 30A): vesica with a row of spines laterally and with two sclerotizated spined lobes; processus gonopori long and slender.   
 Distribution   
Brazil (Fig. 29).  
 Etymology
