description: HERAEUS ANTENNALIS SP. NOV.
(FIGS 15 B, 16B, 17E–H, 18)
Diagnosis
Strongly setose. Labium extending to mesocoxae. Basiflagellomere clavate. Anterior pronotal lobe dark brown, posterior lobe paler with humeral angles concolorous. Profemur pale brown, mottled with brown. Hemelytra uniformly pale brown, with a white subapical corial spot. Aedeagus spinose, with spines forming an arc on sclerotized vesical lobes.
Heraeus antennalis sp. nov. and H. splendens sp. nov. are the only two species in the genus with the basiflagellomere clavate. Heraeus antennalis sp. nov. is strongly setose, with mottled profemora, and the posterior pronotal lobe uniformly pale brown, whereas H. splendens sp. nov. is less setose, with a pale invert- ed V-shaped mark on the posterior pronotal lobe, the profemora are dark but paler dorsally, and the outer margin of clavus is pale.
Description (Fig. 15 B)
Total length 6.36. Strongly setose.
Head: Reddish brown, with an elongate neck and short recumbent and long erect setae. Head length 1.46, width 0.99. Postocular length 0.62. 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 0.53, interocellar width 0.27. Labium brown, with erect setae, extending to mesocoxae. Labial segment lengths: I 0.66, II 0.80, III 0.62, and IV 0.32. Antenna brown, pedicel and base of basiflagellomere paler, with short recumbent and sparse short erect setae, distiflagellomere with a narrow sub-basal whitish band. Basiflagellomere clavate. Antennal lengths: scape 0.43, pedicel 1.23, basiflagellomere 0.96, and distiflagellomere 1.06. Length of pale band on distiflagellomere 0.32.
Thorax: Anterior pronotal lobe dark brown, posteri- or lobe paler, humeral angles concolorous; collar impunctate, delimited posteriorly by a sulcus; anteri- or and posterior lobes with long erect setae, posterior lobe with short recumbent setae. Pronotum pruinose, posterior lobe punctate. Collar length 0.10, anterior lobe length 0.55, posterior lobe length 0.55; anterior lobe width 0.94, posterior lobe width 1.47. Pleurae dark brown, acetabular areas paler, punctate, with short recumbent setae. Evaporative area extended. Scutellum brown darker at base and along a longitudinal line to the apex, with long erect setae. Hemelytra pale brown, pattern as in Figure 15 (B); inner corial spot diffuse, subapical corial spot present. Membrane brown, with veins paler and with a pale apical spot. Legs: Pale brown except mottled profemur, metafemur with a subapical dark band; and meso- and metatibia with a subproximal dark band, apex of tibiae darker (Fig. 16 B). Profemur with long erect setae.
Abdomen: Dark brown to reddish brown, with abundant short recumbent setae. Male genitalia: Pygophore (Fig. 17 E, F) rounded, anterior margin of dorsal aperture rounded. Parameres: Figure 17 (G, H). Aedeagus spinose, with spines forming an arc on sclerotized vesical lobes; processus gonopori long and slender.
Distribution
Ecuador (Fig. 18).
Etymology
The specific ephitet is a noun and refers to the clavate basiflagellomere of the antenna.
Type material
Holotype: ♂, ECUADOR: Yanayacu, 400 m a.s.l., IX/ X-1977, L.E. Peña G. (USNM).
