Treatment

HERAEUS SIMILIS View in CoL SP. NOV.

( FIGS 15 View Figure 15 G, 20I–L, 21A, 22)

Diagnosis

Ocelli located posteriorly. Distiflagellomere with a subbasal pale band. Labium extending to metacoxae. Profemur irregularly pigmented; metafemur with a subapical dark band. Posterior margin of pygophore slightly bilobed.

Heraeus similis sp. nov. shares with H. chamamecinus sp. nov. and H. illitus a highly setose body and the presence of a weakly bilobed posterior margin of pygophore, but it can be distinguished by the length of the labium extending to the metacoxae (whereas it attains abdominal segment II in H. illitus and extends to the mesocoxae in H. chamamecinus sp. nov.).

Description ( Fig. 15 View Figure 15 G)

Total length 6.56. Strongly setose.

Head: Convex dorsally, dark brown, shiny, with short recumbent and long erect setae. Head length 1.44, width 0.96. Postocular length 0.54. Eyes protruding, not surpassing the dorsal margin of head in lateral view. Ocelli placed posterior to an imaginary line passing the posterior border of eyes. Interocular width 0.48, interocellar width 0.29. Labium pale brown with long erect setae, extending to metacoxae. Labial segment lengths: I 1.01, II 1.12, III 1.12, and IV 0.40. Antennal tubercles parallel. Antennae: Scape brown, pedicel and basiflagellomere light brown, darkened apically, distiflagellomere brown with a sub-basal pale brown band; all segments with short semi-erect and erect setae, pedicel with abundant erect setae, equal to or longer than diameter of segment. Antennal lengths: scape 0.53, pedicel 1.36, basiflagellomere 1.15, distiflagellomere 1.28. Length of pale band on distiflagellomere 0.38.

Thorax: Pronotum pruinose, anterior lobe dark brown, posterior lobe brown with pale areas, each humeral angle with a small pale spot. Anterior and posterior lobes with short recumbent and long erect setae, posterior lobe with shorter setae. Pronotum punctate, punctures more conspicuous on posterior lobe. Collar length 0.10, anterior lobe length 0.69, posterior lobe length 0.54; anterior lobe width 1.01, posterior lobe width 1.52. Pleurae dark brown. Evaporative area extended. Scutellum dark brown, pruinose, punctate, with setae similar to pronotal setae. Hemelytra pruinose, with erect setae, costal margin pale on proximal three-quarters, with a subapical corial spot, and an inner corial spot, colour pattern as in Figure 15 View Figure 15 (G). Membrane dark, veins paler, with a pale apical spot. Legs: Coxae and protrochanter reddish brown, remainder of legs pale brown, profemur spotted with brown and with a subapical brown band; meso- and metafemur with a sub-basal brown band, meso- and metatibia with a pale-brown band subbasally, apex of tibiae, distal half of tarsus I, and pretarsus darker ( Fig. 21 View Figure 21 A). Setae long and erect, longer on profemur.

Abdomen: Brown with abundant, short, recumbent setae. Male genitalia: Pygophore ( Fig. 20 View Figure 20 I, J) subquadrangular, with posterior margin weakly bilobed, anterior margin of dorsal aperture rounded. Parameres: Figure 20 View Figure 20 (K, L). Aedeagus: conjunctiva spined; lobes strongly sclerotized and with many spines; processus gonopori long and slender.

Distribution

Argentina, Bolivia, Brazil, French Guiana, and Peru ( Fig. 22 View Figure 22 ).

Etymology

The specific epithet ‘ similis ’, Latin for like, refers to the strongly setose body that is similar to and shared with H. chamamecinus sp. nov. and H. illitus .
