Description
(FIGS 3 A, 4A–C, 5A, 6A–D, 7)
Diagnosis
Diagnosis Head shiny, contrasting with a dull pronotum and hemelytra. Pronotum and scutellum without erect setae. Distiflagellomere and hemelytra uniformly coloured cinnamon brown. Profemora pale yellowish brown. Heraeus cinnamomeus and H. costalis sp. nov. are the only two 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. cinnamomeus is cinnamon brown, with distiflagellomeres and hemelytra uniformly coloured, whereas H. costalis sp. nov. is dark brown with the distiflagellomere mostly white and with the apex darker.
Description
Redescription (Fig. 3 A) Paratype ♂ Head: Strongly convex dorsally (Fig. 4 A). Colour orange brown, shiny and smooth, with short recumbent and erect setae dorsally. Eyes slightly protruding, not surpassing the dorsal margin of head in lateral view. Ocelli posterior to an imaginary line passing the posterior border of eyes. Labium pale brown with erect setae, extending to mesocoxae. Antennae pale brown, distiflagellomere slightly paler; with short recumbent, semi-erect, and erect setae. Thorax: Pronotum dull brown, anterior lobe darker; pruinose, punctate (Fig. 4 B); collar punctate, delimit- ed posteriorly by a sulcus and a row of punctures, anterior pronotal lobe with punctures more conspicuous posteriorly, posterior pronotal lobe coarsely punctate; anterior and posterior lobes with minute setae. Pleurae brown. Evaporative area short. Scutellum brown, pruinose (Fig. 4 C), punctate, with minute recumbent setae. Hemelytra pale brown, pruinose (Fig. 4 C), with minute recumbent setae. Corium with a diffuse subapical pale spot; lateral margins slightly concave. Membrane pale brown, veins concolorous. Legs pale brown, coxae and apical third of metafemur, and apex of tibiae, darker (Fig. 5 A); with sparse, short, recumbent and erect setae. Tibiae with spiniform setae. Profemur conspicuously incrassate in males; spines on profemur small, except for one much larger spine. Protibia with small tubercles bearing spiniform setae in a row along inner surface. Abdomen: Brown, with abundant short recumbent setae. Male genitalia: Pygophore (Fig. 6 A, B) rounded, anterior margin of dorsal aperture slightly rounded, inner projections projecting posteriorly. Parameres: Figure 6 (C, D). Aedeagus: Conjunctiva unspined, vesica with small spines, lobes of vesica strongly sclerotized at base; processus gonopori long and slender.
Distribution
Distribution Mexico (NEW RECORD) and USA (Fig. 7).

Diagnosis
Diagnosis Heraeus coquilletti can be easily distinguished from all other species of the genus by the shiny head, pronotum, and hemelytra with minute setae. In addition, the distiflagellomeres and hemelytra are uniformly brown and the aedeagus has minute spines on conjunctiva and vesica.
Description
Redescription Body shiny, with minute setae on head, pronotum, scutellum and hemelytra (Fig. 3 B). Head: Strongly convex dorsally, orange–brown, smooth, with sparse short recumbent setae. Head transversely rugose ventrally. Eyes slightly protruding, small (larger in specimens from Mexico), not surpassing the dorsal margin of head in lateral view. Ocelli posteri- or to an imaginary line passing through posterior border of eyes. Labium pale brown with short erect setae, extending to mesocoxae. Antennal tubercles divergent. Antennae pale brown, with short recumbent and scattered erect setae, basiflagellomere and distiflagellomere darker, with more abundant setae.
Thorax: Pronotum dark orange–brown, smooth (Fig. 4 D); posterior lobe paler than anterior lobe; punctate, punctures more conspicuous and abundant on posterior lobe; anterior lobe with sparse, minute, erect setae. Pleurae orange–brown. Evaporative area short. Scutellum orange–brown, punctate. Hemelytra shiny, smooth (Fig. 4 E), pale brown, with abundant punctures. Membrane smoky pale brown. Legs: Coxae orange–brown, femora, tibiae, and tarsi pale brown, except apex of each tibia darker, meso- and metafemur slightly darkened apically (Fig. 5 B). Male profemur strongly enlarged with two rows of spines along ventral region, four spines from the apex on posterior row longer and curved anteriorly, with short and sparse setae. Protibia with numerous small tubercles, metatibia with spiniform setae.
Abdomen: Orange–brown with short sparse recumbent setae. Male genitalia: Pygophore (Fig. 6 E, F) rounded, anterior margin of dorsal aperture rounded, inner projections subrectangular. Parameres: Figure 6 (G, H). Aedeagus (Fig. 8 A): conjunctiva with a few minute spines laterally; lobes of vesica slightly sclerotized, with a few minute spines laterally and distally; processus gonopori long and slender.

Distribution Mexico and USA (Fig. 7).
Discussion
Remarks Barber (1914a) based his original description on two males and two females from Standford University, California (Nathan Banks Collection), and a female from Brownsville, Texas, USA, that was referred to as H. cinnamomeus by Barber (1948).
Materials Examined
Type material examined To ensure nomenclatural stability, we select a male syntype in the USNM collection with the following labels as the lectotype of H. coquilletti: Label 1, ‘Stan[ford] U[.], Cal[.], 24 Dec 1909’; 2 (red) ‘Cotype’; 3, ‘H.G. Barber Collection’; 4 (handwritten), ‘ Heraeus coquilletti Barber [,]♂[,] Cotype’; 5 (red, here added), Lectotype: ♂, Heraeus coquilletti Barber, desig. by Dellapé, Melo, & Henry’. A female labelled as co-type, also in the USNM collection, and a male (missing the head) in the AMNH collection with the same locality data are considered paralectotypes.
