Caulotops barberi Knight 1926: 101(original description); Carvalho 1957: 94(catalog); Knight 1968: 79(distribution, host); Henry and Wheeler 1988: 265(catalog); Schuh 1995: 540(catalog), 2002–2013(online catalog).
DIAGNOSIS. A. barberi( Figs. 14, 15) is distinguished by the pale red to reddish-orange head and the fuscous clypeus, the dark brown to black antennae, the pale yellowish-brown pronotum often with reddish-orange calli, the reddishorange scutellum, the dark brown, weakly shining hemelytra with weak bluish sheen, the pale legs with a few small dark spots on the femora, and the slender apically pointed tubercle ( Fig. 120) on the genital capsule. This species is most similar to A. scutellatusin overall color and antennal proportions. It can be separated from A. scutellatusby larger average size ( 4.15–4.90 mmin ♂♂, 4.70–5.05 in ♀♀; versus 4.10–4.30 mmin ♂♂, 4.10– 4.60 mmin ♀♀), the more open C-shaped left paramere ( Fig. 73), and the slender, apically acute genital tubercle (vs. stout and apically rounded).
REDESCRIPTION. Male(n = 4; holotypemeasurements in parentheses; note: the holotypeis smashed and slightly flattened, probably accounting for the greater length and broader head and pronotum): Length from apex of head to cuneal fracture 2.85–3.35 mm( 3.60 mm); length from apex of head to apex of membrane 4.15–4.45 mm( 4.90 mm); widest width 1.86–1.92 mm( 1.92 mm). Head: Width across eyes 1.23–1.26 mm( 1.30 mm), interocular width 0.74–0.75 mm( 0.75 mm). Antenna: Segment I length 0.45–0.48 mm( 0.48 mm); II, 0.88–0.96 mm( 0.96 mm); III, 0.69–0.72 mm(missing), IV, 0.67–0.75 mm(missing). Labium: Length 1.63–1.80 mm( 1.75 mm), extending to abdominal segment III or IV. Pronotum: Posterior width 1.34–1.39 mm( 1.46 mm); median length 0.67–0.74 mm( 0.72 mm). Macropterous, medium-sized, elongate oval. COLORATION. Head: Pale yellowish orange to pale reddish orange, vertex with two weak transverse brown lines, frons with two parallel rows of brown lines on either side of middle; clypeus dark brown. Labium: Pale yellowish brown. Antenna: Segment I yellowish brown, with a dark ring at base; segments II–IV yellow brown to brown. Pronotum: Pale yellowish brown, calli reddish orange to fuscous. Mesoscutum and scutellum: Reddish orange. Hemelytron: Dark brown, semishiny, with a weak bluish sheen; translucent smoky brown, veins dark brown. Ventral surface: Pale yellowish brown to brown; abdomen reddish brown; pointed genital tubercle brown. Legs: Coxae pale yellowish brown; femora pale yellowish brown, with a few small dark spots on either side, hind femur infuscated on apical half; tibiae and tarsi yellowish brown; claws dark brown. STRUCTURE, SURFACE, and VESTITURE. As in generic description. Male genitalia: Endosoma and phallotheca as in generic description. Left paramere ( Fig. 73). Right paramere ( Fig. 74). Genital tubercle ( Fig. 120) elongate, apically pointed. Female: (n = 5): Length from apex of head to cuneal fracture 3.40–3.75 mm; length from apex of head to apex of membrane 4.70–5.05 mm; widest point across hemelytra 2.05–2.20 mm. Head: Width across eyes 1.34–1.41 mm; interocular width 0.80–0.83 mm. Labium: Length 1.88–2.00 mm. Antenna: Segment I length 0.50–0.56 mm; II, 0.94– 1.04 mm; III, 0.60–0.72 mm; IV, missing. Pronotum: Median length 0.80–0.85 mm; posterior width 1.52–1.62 mm. Similar to male in size, shape, and coloration.

DISCUSSION.This species was described from a unique male holotype. We now have six females collected near the type locality in Santa Cruz Co., and numerous other specimens, including males, from Coconino, Gila, and Yavapai counties, Arizona, and six from Chihuahua statein Mexicothat allow us to confirm the identity of this species. Knight (1968)separated it from A. agavisbased on the supposed longer total body length (when measured over longer series, there is considerable overlap), and a shorter 2nd antennal segment not equal to the width of the vertex and the dorsal width of an eye. We also note that A. barberihas a long, slender, apically narrowed genital tubercle ( Fig. 120), whereas in A. agavisand all other species included in Agaveocoris(e.g., Figs.119, 121, 122), the tubercles are shorter, much stouter, and apically blunt or rounded.
