HERAEUS COSTALIS View in CoL SP. NOV.

( FIGS 3C View Figure 3 , 5C View Figure 5 , 6I–L View Figure 6 , 7 View Figure 7 , 8B View Figure 8 )

Diagnosis

Head shiny, contrasting with dull pronotum and hemelytra. Distiflagellomeres mostly white, with apex darker. Scutellum without erect setae. Profemur mostly dark brown.

Heraeus costalis sp. nov. and H. cinnamomeus are the only species of the coquilletti group that have a shiny head, contrasting with a dull pronotum and hemelytra, and the scutellum lacking erect setae. The general colouration of H. costalis sp. nov. is dark brown, with the distiflagellomere mostly white with the apex darker, whereas the general colouration of H. cinnamomeus is cinnamon brown, with distiflagellomere and hemelytra uniformly coloured.

Description

Total length 6.27 ( Fig. 3C View Figure 3 ).

Head: Convex dorsally, dark reddish brown, shiny, smooth, with short recumbent and long, erect setae. Head length 1.34, width 0.91. Postocular length 0.48. Eyes with setae between ommatidea; not surpassing the dorsal margin of head in lateral view. Ocelli posterior to an imaginary line passing the posterior border of eyes. Interocular width 0.46, interocellar width 0.27. Labium pale brown with erect setae, extending to mesocoxae. Labial segment lengths: I 0.93, II 0.96, III 0.88, and IV 0.37. Antennae brown, except scapus darker and distiflagellomere paler with a broad diffuse subbasal yellowish band, and abundant short recumbent and sparse erect setae. Antennal lengths: scape 0.62, pedicel 1.26, basiflagellomere 0.94, and distiflagellomere 1.30. Length of pale band on distiflagellomere 0.72.

Thorax: Pronotum pruinose, with sparse, short, recumbent, and erect setae. Pronotum dark brown; anterior lobe darker; humeral angles with a small pale spot. Pronotum more conspicuously punctate on posterior lobe. Collar length 0.07, anterior lobe length 0.86, posteri- or lobe length 0.48; anterior lobe width 0.98, posteri- or lobe width 1.50. Pleurae dark brown, acetabular areas reddish brown; punctate, with short recumbent setae. Evaporative area short. Scutellum dark brown, pruinose, punctate, with short recumbent setae. Hemelytra pruinose, with short recumbent setae. Hemelytron brown, claval commisure and about apical half of inner margin of clavus, base of corium, anterior threequarters of lateral margins, and a small subapical spot yellowish; apex of corium and adjacent area of membrane pale, membrane pale brown with a diffuse pale apical spot, veins concolorous. Legs: Coxae and protrochanters reddish brown; profemur reddish brown, except base and apex paler; meso- and metafemur bicoloured, base yellowish and apex brown; tibiae and tarsi pale brown, apex of tibiae darker ( Fig. 5C View Figure 5 ). With sparse, short, semi-erect setae. Profemur conspicuously incrassate, spines on profemur small except for one spine contrastingly larger. Protibia with small tubercles bearing spiniform setae on inner surface.

Abdomen: Reddish brown; with abundant, short, recumbent setae. Male genitalia: Pygophore ( Fig. 6I, J View Figure 6 ) rounded, anterior margin of dorsal aperture slightly rounded, inner projections subquadrangular; declivent posteriorly in lateral view. Parameres: Figure 6 View Figure 6 (K, L). Aedeagus ( Fig. 8B View Figure 8 ): conjunctiva with spines laterally beneath the ejaculatory reservoir; vesica with a few minute spines laterally and two sclerotized lobes with a few minute spines distally; processus gonopori long and slender.

Distribution

Costa Rica, Guatemala, Honduras, and Nicaragua ( Fig. 7 View Figure 7 ).

Etymology

This species is named ‘ costalis ’ to denote the pale costal margin of the hemelytra.
