Heraeus annulatus

Pablo M. Dellapé, María C. Melo & Thomas J. Henry, 2016, A phylogenetic revision of the true bug genus Heraeus (Hemiptera: Rhyparochromidae: Myodochini), with the description of two new genera and 30 new species, Zoological Journal of the Linnean Society 177 (177), pp. 29-134 : 60-64

HERAEUS ANNULATUS SP. NOV.

( FIGS 15 A, 16A, 17A–D, 18)

Diagnosis

Labium extending to mesocoxae. Pedicel with abundant erect setae, equal to or longer than diameter of segment; distiflagellomere with a pale band subbasally. Collar delimited by a furrow; with long erect setae only on anterior pronotal lobe; profemur mottled, with the base and a subapical band darker; metatibia yellowish. The combination of these last four characters allows us to separate H. annulatus sp. nov. from the other species of the genus.

Description ( Fig. 15 A)

Total length 5.80. Strongly setose species.

Head: Flattened dorsally, dark brown clypeus paler, shiny, with abundant short recumbent and long erect setae. Head length 1.15, width 0.93. Postocular length 0.41. Eyes not surpassing the dorsal margin of head in lateral view; with long erect setae between ommatidea. Ocelli placed at level of an imaginary line passing the posterior border of eyes. Interocular width 0.45, interocellar width 0.27. Labium pale brown with short erect setae, almost extending to mesocoxae. Labial segment lengths: I 0.53, II 0.72, III 0.61, and IV 0.35. Antennae pale brown except apex of basiflagellomere and distiflagellomere darker, distiflagellomere with a pale band sub-basally; setae short recumbent and semi-erect, pedicel with abundant erect setae, equal to or longer than diameter of segment; basiflagellomere slightly clavate. Antennal lengths: scape 0.48, pedicel 1.04, basiflagellomere 0.86, distiflagellomere 1.04. Length of pale band on distiflagellomere 0.40.

Thorax: Anterior pronotal lobe dark brown, posteri- or lobe reddish brown with irregular pale areas, humeral angles yellowish; pruinose, with short recumbent and long erect setae, longer on anterior lobe. Pronotum punctate, punctures more conspicuous on posterior lobe. Collar delimited by a furrow, length 0.08, anterior lobe length 0.53, posterior lobe length 0.50; anterior lobe width 0.91, posterior lobe width 1.41. Pleurae brown, acetabular areas reddish brown; punctate, with abundant, short, recumbent setae. Evaporative area extended. Scutellum dark brown, pruinose, punctate, with short recumbent and long erect setae, as on the anterior lobe. Hemelytra pruinose, with short semierect 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 fuscous, with an apical pale spot, veins paler ( Fig. 15 A). Legs: Coxae and protrochanter brown, rest of leg whitish, profemur mottled, with base and a subapical band brown; meso- and metafemur with a subapical brown band; tibiae brown apically ( Fig. 16 A); setae long and erect, longer on profemur. Profemur with spines restricted to apical two-thirds.

Abdomen: Brown, with abundant, short, recumbent setae. Male genitalia: Pygophore ( Fig. 17 A, B) rounded, anterior margin of dorsal aperture rounded, inner projections elongate, more produced posteriorly; slightly declivent posteriorly in lateral view. Parameres: Figure 17 (C, D). Aedeagus: conjunctiva with spines laterally, beneath the ejaculatory reservoir; two lobes sclerotized with a few spines distally; processus gonopori long and slender.

Distribution

Belize, Costa Rica, Honduras, Mexico, and Panama ( Fig. 18 ).

Etymology

The specific ephitet ‘ annulatus ’ is a Latin adjective meaning ringed, and refers to the presence of a subapical band on the profemur.
