Treatment

HERAEUS DOMINICANUS View in CoL SP. NOV.

( FIGS 3 View Figure 3 K, 5G, 9I–L, 10)

Diagnosis

Posterior pronotal lobe uniformly brown; meso- and metafemora reddish, pale basally; labium long, extending to metacoxae.

The uniformly brown posterior pronotal lobe easily distinguishes H. dominicanus sp. nov. from H. caliginosus . Also, H. dominicanus sp. nov. has a shorter rostrum that extends only to the metacoxae.

Description

Total length 6.64 ( Fig. 3 View Figure 3 K).

Head: Strongly convex dorsally, brown, smooth, and shiny, with short recumbent and long erect setae dorsally. Head length 1.55, width 0.99. Postocular length 0.59. Eyes slightly protruding, not surpassing the dorsal margin of head in lateral view. Ocelli placed at level of an imaginary line passing posterior border of eyes. Interocular width 0.50, interocellar width 0.26. Labium light brown with erect setae, extending to meso- or metacoxae (pinned through posterior pronotal lobe). Labial segment lengths: I 0.94, II 1.04, III 0.80, and IV 0.24. Antenna light brown, scapus darker, basiflagellomere reddish distally; with abundant short recumbent and sparse, short, erect setae. Antennal lengths: scape 0.67, pedicel 1.44, basiflagellomere 1.28, and distiflagellomere missing.

Thorax: Pronotum dull, pruinose, uniformly brown, punctate, punctures more conspicuous on posterior lobe; setae short and recumbent, anterior pronotal lobe with long erect setae. Collar length 0.11, anterior lobe length 0.78, posterior lobe length 0.56; anterior lobe width 0.99, posterior lobe width 1.55. Pleurae brown. Evaporative area short. Scutellum brown, punctate, pruinose, with long erect setae. Hemelytra pruinose, with short recumbent setae; general colour brown, darkened on posterior half, with a large whitish subapical corial spot. Membrane brown, with an elongate pale apical spot, veins concolorous. Legs: Femora reddish brown, meso- and metafemur paler basally, tibiae pale reddish brown, tarsi pale brown ( Fig. 5 View Figure 5 G). Legs with semi-erect and erect setae; protibia with small spines on inner surface.

Abdomen: Brown, shiny, with abundant short recumbent setae. Male genitalia: Pygophore ( Fig. 9 View Figure 9 I, J) rounded. Anterior margin of dorsal aperture slightly rounded. Parameres: Figure 9 View Figure 9 (K, L). Aedeagus with minute spines, vesical lobes sclerotized; processus gonopori long and slender.

Variability observed in a female paratype Distiflagellomeres uniformly light brown, without a pale band. Spines of profemur small and restricted to apical half.

Distribution

Dominican Republic ( Fig. 10 View Figure 10 ).
