Pilophoropsis cunealis Henry sp. n. Figs 76-78, 266-268

Diagnosis.

This species (Figs 76-78) is distinguished by the posterior band of silvery scale-like setae bordering the cuneal fracture and the male genitalia, particularly the long, slender middle process of the left paramere (Fig. 266), the expanded, T-shaped apex of the lateral arm on the right paramere (Fig. 268), and the long, slender apical process of the phallotheca (Fig. 267).

Description.

Male (n = 2; holotype measurements in parentheses): Length 2.85 mm (2.98 mm), width 0.99 mm (1.01 mm). Head: Width 0.69 mm (0.70 mm), interocular width 0.30 mm (0.31 mm). Labium: Length 1. 04 mm (1.09 mm). Antenna: Segment I, length 0.21 mm (0.21 mm); II, 0.59 mm (0.61 mm); III, 0.30 mm (0.33 mm); IV, missing (0.35 mm). Pronotum: Length 0.72 mm (0.72 mm), basal width 0.86 mm (0.91 mm).

Coloration: Head: Dark brown, clypeus, jugum, lorum, and area around base of antenna paler brown. Antenna: Segment I pale brown with a dark reddishbrown band on anterior and inner surface near base; segments II– IV dark brown; apex of II, apical half of III, and IV swollen. Pronotum: dark brown, anterior area around collar more yellow or yellowish brown. Scutellum: Pale yellowish brown. Hemelytron: Brown, with inner margin of clavus and basal half of corium inside radial vein pale yellowish brown, cuneus reddish; membrane uniformly brown;. Legs: Coxae pale yellow or whitish, with a few red marks apically; femora reddish brown, middle and hind femora pale on basal fourth; tibiae reddish brown on basal third to half, pale yellow beyond; tarsi pale yellow; claws pale brown. Ventral surface: Uniformly reddish brown, abdominal patch paler brown. Ostiolar evaporative area: White, weakly tinged with red dorsally.

Structure, texture, and vestiture: Labium: Extending to apices of middle coxae. Pronotum: Shiny, impunctate; narrowed anterior area around calli granulate, disk smooth. Scutellum: Base partially hidden by base of pronotum; lacking scale-like setae. Hemelytron: Embolium and cuneus polished, remainder of corium dull; corium and base of cuneus with numerous stout, black, bristle-like setae, clavus with six or more short, transverse bands of silvery scale-like setae, outer margin of corium bordering embolium with two short transverse bands, one on basal third and one at middle, apex of corium bordering cuneus with a large transverse band of silvery scale-like setae disjunct at middle (Figs 76, 77).

Male genitalia: Aperture of capsule smooth, lacking spines or processes. Left paramere (Fig. 266) with beak-like process more quadrate; basal process with a long, slender apex. Right paramere (Fig. 268) with lateral arm T-shaped apically. Phallotheca (Fig. 267) with a long, curved, apically acute process.

Macropterous female (n = 4): Length to apex of abdomen 2.46-2.85 mm, length to base of cuneus 1.98-2.18 mm, width 1.04-1.10 mm. Head: Width 0.69-0.75 mm, interocular width 0.35-0.42 mm. Labium: Length 1.06-1.14 mm. Antenna: Segment I, length 0.19-0.22 mm; II, 0.58-0.61 mm; III, 0.32-0.35 mm; IV, 0.30-0.35 mm. Pronotum: Length 0.61-0.72 mm, basal width 0.74-0.85 mm. Color and structure much as in males, including the structure of the pronotum and hemelytra, with the membrane only slightly more abbreviated than fully developed males.

Etymology.

Named “cunealis” to denote the posterior band of silvery scale-like setae along the cuneal fracture, a character unique among species of the genus.

Host.

Acacia cochliacantha Humb. & Bonpl. ex. Willd. [ Fabaceae ].

Distribution.

Known only from Oaxaca, Mexico.

Discussion.

unlike the strongly modified females of other species in the genus, such as Pilophoropsis brachyptera , females of Pilophoropsis cunealis are almost fully macropterous as in males, except for the slightly abbreviated hemelytral membrane and, in one case, a slightly more shortened cuneus.
