HERAEUS ILLITUS DISTANT, 1882

( FIGS 8 H, 15D, 16D, 17M–P, 19)

Heraeus illitus Distant, 1882: 205 ; Distant, 1893: 397; Lethierry & Severin, 1894: 191; Scudder, 1967: 268 (lectotype designation); Slater, 1964: 1083; Slater & O’Donnell, 1995: 147; Harrington, 1980: 109; Froeschner, 1999: 244; Slater & Brailovsky, 2000: 332; Baranowski & Slater, 2005: 142.

Diagnosis

Strongly setose. Ocelli located posteriorly. Distiflagellomere with a pale band. Labium extending to abdominal sternum II. Profemur irregularly pigmented; metafemur with a darker subapical band. Posterior margin of pygophore in dorsal view slightly bilobed; aedeagus with conjunctiva and vesica with a few spines laterally, and lobes sclerotized posteriorly, with spines forming an arc.

Heraeus illitus shares with H. chamamecinus sp. nov. and H. similis sp. nov. a strongly setose body and a slightly bilobed posterior margin of pygophore. Heraeus illitus and H. caliginosus are the only species of the genus that have a long labium exceeding the metacoxae.

Redescription ( Fig. 15 D)

Strongly setose.

Head: Convex dorsally, dark brown, clypeus paler, shiny, with short recumbent setae. Eyes protruding, not surpassing the dorsal margin of head in lateral view. Ocelli placed posteriorly to an imaginary line passing the posterior border of eyes. Labium pale brown, extending to base of abdomen, with short erect setae. Antennal tubercles parallel. Antennae pale brown except apex of pedicel, basiflagellomere and distiflagellomere darker, distiflagellomere with a pale band subbasally; all segments with short recumbent and semierect setae, pedicel with abundant erect setae, equal to or longer than diameter of segment.

Thorax: Pronotum brown, pruinose, posterior lobe with irregular pale areas and a pale spot on humeral angles, anterior and posterior lobes with short recumbent and long erect setae. Pronotum punctate, punctures more conspicuous on posterior lobe. Pleurae brown, with semi-erect setae. Evaporative area extended. Scutellum dark brown, pruinose, punctate, with short recumbent, and long erect setae. Hemelytra pruinose, with abundant erect setae. General colour pale brown, costal margin pale on proximal three-quarters. Corium darker distally, with a subapical whitish spot and a rounded pale spot internally. Membrane testaceous, with an apical rounded pale spot, veins paler. Legs pale brown, coxae darker, profemur darker and irregularly pigmented; metafemur with a subapical darker band, only slightly evident on mesofemur. Meso- and metatibiae with a subproximal dark band, apices darker ( Fig. 16 D), with long erect setae, longest on profemur. Profemur with spines restricted to apical threequarters.

Abdomen: Brown, with abundant, short, recumbent, and longer erect setae. Male genitalia: Pygophore subquadrangular ( Fig. 17 M, N), posterior margin slightly bilobed; anterior margin of dorsal aperture rounded, inner projections large and subrectangular. Parameres as shown in Figure 17 (O, P). Aedeagus ( Fig. 8 H): conjunctiva and vesica with spines laterally; lobes sclerotized posteriorly, with spines forming an arc; processus gonopori long.
