Treatment

HERAEUS SETOSUS View in CoL SP. NOV.

( FIGS 3E View Figure 3 , 5E View Figure 5 , 7 View Figure 7 , 8C View Figure 8 , 9A–D View Figure 9 )

Diagnosis

Antennae uniformly coloured; pronotum, scutellum, and hemelytra with erect setae; labium extending to or slightly beyond metacoxae.

Heraeus setosus sp. nov. and H. itzelae sp. nov. have long erect setae on pronotum and scutellum. In H. setosus sp. nov., the hemelytra also have erect setae, the distiflagellomere lacks a pale band, and the labium extends to the metacoxae, whereas in H. itzelae sp. nov., the distiflagellomere has a pale band, the hemelytra have only scattered, short, recumbent setae, and the labium is shorter, extending to mesocoxae.

Description

Total length 6.46 ( Fig. 3E View Figure 3 ). Strongly setose species.

Head: Strongly convex dorsally, brown, coriaceous with abundant recumbent and erect setae. Head length 1.27, width 0.88. Postocular length 0.41. Eyes slightly protruding, not surpassing dorsal margin of head in lateral view. Ocelli posterior to an imaginary line passing the posterior border of eyes. Interocular width 0.45, interocellar width 0.30. Labium light brown with erect setae, extending to metacoxae. Labial segment lengths: I 0.90, II 0.99, III 0.90, and IV 0.37. Antennal colouration yellowish brown. Pedicel with abundant erect setae, equal to or longer than diameter of segment. Antennal lengths: scape 0.62, pedicel 1.60, basiflagellomere, and distiflagellomere missing.

Thorax: Pronotum pruinose; punctate, those of anterior lobe shallow; dark brown, posterior lobe and humeral angles paler; pruinose, with abundant, long, erect setae. Collar length 0.08, anterior lobe length 0.82, posterior lobe length 0.54; anterior lobe width 1.14, posterior lobe width 1.68. Pleurae brown. Evaporative area short. Scutellum brown, pruinose, punctate, with abundant long erect setae. Hemelytra pruinose, brown, with abundant erect setae shorter than those on scutellum; clavus unicolorous; costal margin pale on proximal three-quarters. Inner corial spot well defined. Membrane brown, veins paler. Legs: Coxae and protrochanter brown; profemur brown with apex paler, rest of legs pale brown; meso- and metafemur slightly darkened distally, tibiae darker at apices ( Fig. 5E View Figure 5 ). Strongly setose, with long erect and semi-erect setae. Protibia with small tubercles bearing spiniform setae on inner surface.

Abdomen: Brown with abundant short recumbent setae. Male genitalia: Pygophore rounded, anterior margin of dorsal aperture slightly rounded ( Fig. 9A, B View Figure 9 ). Parameres: Figure (9C, D). Aedeagus with minute spines; vesical lobes sclerotized; processus gonopori long and slender ( Fig. 8C View Figure 8 ).

Variability observed in paratypes

All antennal segments yellowish brown.

Distribution

Honduras and Mexico ( Fig. 7 View Figure 7 ).

50 A REVISION OF HERAEUS ( RHYPAROCHROMIDAE )

Etymology

This species is named ‘ setosus ’, Latin for bristly, to denote the long, erect dorsal setae.
