Pilophoropsis quercicola Henry sp. n. Figs 82, 83, 272-275

Diagnosis.

This species (Figs 82, 83) is recognized by the general dark color, the wide band of silvery scale-like setae transversing the corium level with the apex of the clavus, and the male genitalia, particularly the left paramere (Fig. 272) with three middle processes, the stout, bifurcate lateral arm of the right paramere (Figs 274, 275), and the unique recurved apical process of the phallotheca (Fig. 273).

Description.

Male (n = 2; holotype measurements in parentheses): Length 3.16 mm (3.30 mm), width 0.96 mm (1.04 mm). Head: Width 0.74 mm (0.75 mm); interocular width 0.33 mm (0.34 mm). Labium: Length 1.14 mm (1.18 mm). Antenna: Segment I, length 0.20 mm (0.20 mm); II, 0.55 mm (0.57 mm); III, 0.34 mm (0.35 mm); IV, 0. 38 mm (missing). Pronotum: Length 0.69 mm (0.70 mm); basal width 0.91 mm (0.94 mm).

Coloration: Head: Dark brown to fuscous, paler brown along inner margin of eyes and around antennal bases. Antenna: Segment I brown, with a narrow fuscous stripe and a red spot on inner surface, segments II–IV uniformly dark brown or fuscous. Pronotum: Dark brown. Scutellum: Dark brown to fuscous. Hemelytron: Clavus and corium dull yellowish brown, becoming darker posteriorly; embolium and cuneus shiny reddish brown. Ventral surface: Reddish brown to fuscous; glaucous abdominal stridulatory patch pale. Ostiolar evaporative area: Uniformly white. Legs: Fore coxa white with base narrowly infuscated and apex red tinged, middle coxa white with base infuscated, hind coxa uniformly white; fore femora dark brown, middle and hind femora dark brown with basal thirds whitish; tibiae dark brown, becoming paler on apical thirds; tarsi and claws brown.

Structure, texture, and vestiture: Labium: Extending to bases of middle coxae. Pronotum: Anterior third, granulate, narrowed, sloping toward head, calli indistinct, flattened; posterior two thirds strongly convex, polished, impunctate, basal angles flared. Scutellum: With a band of silvery scale-like setae across base. Hemelytra: Dull area with two distinct bands of silvery, scale-like setae, a narrow one across base of clavus and through scutellum and a broad one across corium at level with apex of clavus, also with 6 patches of silvery scale-like setae, two at emboliar margin on basal half of corium and four on clavus; intermixed with scattered, stout, erect, black, bristle-like setae on dull areas of clavus and corium. Ventral surface: Shiny, with scattered erect and semierect simple setae on abdomen.

Male genitalia: Left paramere (Fig. 272) with three apically acute and one slender basal processes; right paramere (Figs 274, 275) with a bifurcate lateral arm having two small processes arising at base; phallotheca (Fig. 273) stout, with a thick, decurved, beak-like apical process.

Macroperous female : (n = 1): Length 3.00 mm, width 1.11 mm. Head: Width 0.78 mm, interocular width 0.39 mm. Labium: Length 1.24 mm, extending to middle coxae. Antenna: Segment I, 0.21 mm; II, 0.61 mm; III, 0.38 mm; IV, 0.36 mm. Pronotum: Length 0.62 mm, basal width 0.88 mm.

Brachypterous female (n = 3): Length to apex of abdomen 2.65-2.75 mm, length to base of cuneus 2.14-2.24 mm, width 1.00-1.05 mm. Head: Width 0.78-0.79 mm, interocular width 0.40 mm. Labium: 1.18-1.20 mm, extending nearly to bases of hind coxae. Antenna: Segment I, length 0.20 mm; II, 0.86-0.87 mm; III, 0.31-0.35 mm; IV, 0.33-0.36 mm. Pronotum: Length 0.53-0.59 mm, basal width 0.70-0.74 mm.
