Diagnosis

Distiflagellomere with a diffuse pale band, the legs yellowish brown, with the distal third of meso- and metafemur slightly darkened, the posterior pronotal lobe uniformly coloured, and the hemelytra reddish brown, with the apex of corium and most of the membrane darker.

Heraeus triguttatus is most closely related to H. steineri sp. nov., whereas this last species has uniformly whitish legs, the posterior pronotal lobe is mottled with yellow, and the hemelytra are mottled brown with yellow basally.

Redescription ( Fig. 3 H)

Head: Convex dorsally, postocular region elongate; brown, shiny, coriaceous, with short recumbent and erect setae dorsally. Eyes not surpassing the dorsal margin of head in lateral view. Ocelli placed posterior to an imaginary line passing the posterior border of eyes. Labium pale brown, with erect setae, extending to mesocoxae. Antennae pale brown, with abundant recumbent and scattered short erect setae. Distiflagellomere with a pale band, diffuse in some specimens.

Thorax: Pronotum brown, posterior pronotal lobe paler; dull, with scattered short recumbent and long erect setae, shorter on posterior lobe. Males generally with a strongly globose anterior pronotal lobe. Scutellum brown, pruinose, with long erect setae. Pleurae brown. Hemelytra pruinose, dull, with short recumbent setae; posterior half of hemelytra dark with the subapical corial spot and apical spot of membrane conspicuously pale. Membrane fuscous, veins concolorous. Legs: Coxae brown, profemur pale brown, rest of legs yellowish brown, meso- and metafemur slightly darkened distally ( Fig. 11 D). Profemur with sparse short setae. Protibia and male mesofemur spinose.

Abdomen: Pale reddish brown, with abundant short recumbent setae. Male genitalia: Pygophore ( Fig. 12 M, N) rounded, anterior margin of dorsal aperture rounded, inner projections elongate, more pronounced posteriorly. Parameres with a tubercle at base of blade on outer surface ( Fig. 12 O, P). Aedeagus without spines; vesical lobes sclerotized; processus gonopori long and slender.

Distribution

Cuba, Dominican Republic, Jamaica, USA, and the West Indies (Bahamas, South Bimini Island, Grand Cayman Island, and Turks & Caicos Islands; Fig. 14 ).

Type material

According to the original description, the type series consists of three specimens from Cuba. After an unsuccessful search of the Muséum National d’Histoire Naturelle in Paris by Dr Eric Guilbert, we have concluded that the specimens of Lygaeus (Plociomerus) triguttatus are lost. To ensure nomenclatural stability, we are designating the following female neotype (in good condition with only the right antenna missing) deposited in the USNM collection: label 1, ‘Baraguá, Cuba, X-24-26’; label 2, ‘T P R F Ent. No. 188’; label 3, ‘at light’; label 4, ‘C.F. Stahl collector’; label 5 (red, here added), ‘Neotype ♀: Lygaeus triguttatus Guérin- Méneville, desig. by Dellapé, Melo, & Henry’. There is also a male (in good condition, but with both distiflagellomeres missing) in the USNM with the same label data, except for the date X-19-25.
