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.

Redescription

Body shiny, with minute setae on head, pronotum, scutellum and hemelytra (Fig. 3B).

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. 4D); 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. 4E), 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. 5B). 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. 6E, F) rounded, anterior margin of dorsal aperture rounded, inner projections subrectangular. Parameres: Figure 6 (G, H). Aedeagus (Fig. 8A): 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). 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).

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.
