HERAEUS BREVIROSTRIS View in CoL SP. NOV.

( FIGS 25F View Figure 25 , 26F View Figure 26 , 28 View Figure 28 , 30C View Figure 30 , 32E–H View Figure 32 )

Diagnosis

Labium extending to mesocoxae. Distiflagellomere with a narrow sub-basal pale band. Membrane with an apical pale spot. Meso- and metafemur with a narrow subapical brown band. Apex of pygophore with a small protuberance pointed dorsally.

Heraeus brevirostris sp. nov., H. 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; H. brevirostris sp. nov., however, can be distinguished by the shorter labium extending only to mesocoxae, whereas the other species have a longer labium, extending to metacoxae.

Description ( Fig. 25F View Figure 25 )

Total length 5.61.

Head: Dark brown, shiny, coriaceous; with short recumbent setae and erect setae dorsally. Head length 1.15, width 0.85. Postocular length 0.42. 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 0.45, interocellar width 0.29. Labium pale brown with short erect setae, extending to mesocoxae. Labial segment lengths: I 0.78, II 0.88, III 0.72, and IV 0.35. Antennae pale brown, apex of basiflagellomere and distiflagellomere darker, distiflagellomere with a narrow sub-basal pale band; all segments with abundant short recumbent and sparse erect setae. Antennal lengths: scape 0.45, pedicel 1.04, basiflagellomere 0.93, and distiflagellomere 1.02. Length of pale band on distiflagellomere 0.19.

Thorax: Pronotum dark brown, collar and posterior lobe paler, with irregular pale spots, humeral angles with a pale spot; pruinose, punctate, punctures larger on posterior lobe; anterior and posterior lobes with short recumbent and erect setae, longer on anterior lobe. Collar punctate, delimited by a punctate sulcus. Collar length 0.08, anterior lobe length 0.51, posterior lobe length 0.51; anterior lobe width 0.91, posterior lobe width 1.41. Pleurae dark reddish brown, punctate, with short recumbent setae. Evaporative area extended. Scutellum dark brown with a longitudinal darker median stripe, pruinose, punctate, with short recumbent and long erect setae, as on anterior pronotal lobe. Hemelytra: costal margin pale on proximal twothirds, with a subapical corial spot, membrane brown with veins paler and a pale apical spot, colouration pattern complex ( Fig. 25F View Figure 25 ); with short recumbent setae. Legs: Coxae, protrochanter, and profemur dark brown, except apex of profemur and remainder of legs yellowish, with a subapical narrow brown band on meso- and metafemur ( Fig. 26F View Figure 26 ); setae short and semierect, longer on profemur. Profemur with spines on apical two-thirds. Protibia slightly curved.

Abdomen: Brown, with abundant short recumbent setae. Male genitalia: Pygophore ( Fig. 32E, F View Figure 32 ) rounded, anterior margin of dorsal aperture rounded, apex with a small protuberance pointed dorsally; declivent posteriorly in lateral view; inner projections elongate, more produced posteriorly. Parameres: Figure 32 View Figure 32 (G, H). Aedeagus ( Fig. 30C View Figure 30 ) with strong spines, conjunctiva with a few spines laterally; vesica with two spined sclerotized lobes and small unsclerotized lobes anteriorly with a patch of spines; processus gonopori long and slender.

Distribution

Argentina and Bolivia ( Fig. 28 View Figure 28 ).

Etymology

The specific epithet ‘ brevirostris ’ is an adjective meaning short-beaked, and refers to the relatively short labium that extends only to the mesocoxae.
