Pilophoropsidea keltoni Henry sp. n. Figs 59, 234-236

Diagnosis.

This species (Fig. 59) is recognized by the large size; overall reddishbrown coloration; slender body form; the shiny, finely granulate pronotum; and male genitalia, particularly the left paramere (Fig. 234) with a long, slender, apically blunt basal process, and the phallotheca (Fig. 235) with an elongate apical process and deeply toothed subapical area.

Description.

Male (n = 5; holotype measurements in parentheses): Length 4.40-4.80 mm (4.80 mm), width 1.52-1.56 mm (1.54 mm). Head: Width 0.80-0.84 mm (0.83 mm), interocular width 0.26-0.28 mm (0.29 mm). Labium: Length 1.40-1.48 mm (1.52 mm). Antenna: Segment I, length 0.28-0.30 mm (0.27 mm); II, 0.96-1.04 mm (1.04 mm), slender, only slightly thickened to apex; III, 0.52-0.60 mm (0.56 mm); IV, 0.44-0.50 mm (0.50 mm). Pronotum: Length 0.84-0.86 mm (0.85 mm), basal width 1.28-1.32 mm (1.33 mm).

Coloration: Head: Brown to dark reddish brown. Antenna: Segment I pale brown, with a narrow, sometime indistinct, reddish line on inner surface; segments II–IV dark brown. Pronotum: Shiny reddish brown to dark brown. Scutellum: Dark brown. Hemelytron: Shiny orange brown on basal half, shiny reddish brown to dark brown apically; membrane dark smoky brown beyond apex of cuneus, pale or white basally across and between areoles. Ventral surface: Shiny reddish brown, becoming fuscous on abdomen; ostiolar area white with anterior knob dull red. Legs: Coxae whitish, apex of procoxa and bases of middle and hind coxae reddish to reddish brown; femora brown to reddish brown; tibiae brown to reddish brown, fore and middle tibiae paler apically.

Structure, texture, and vestiture: Head: Frons and vertex with transverse, finely granulate striations, with long, erect and semierect, pale, simple setae. Labium: Extending to bases of middle coxae. Pronotum: Disc shiny but with fine scattered granulations, calli and narrow anterior collar more densely granulate, simple pubescence sparse, recumbent. Scutellum: Depressed at middle, granulate, with a wide band of silvery scale-like setae across apical third except apex, intermixed with long, erect, pale, simple setae. Hemelytron: With a narrow band of silvery scale-like setae across base of clavus and a wider band through middle of corium and across apical third of clavus, intermixed on clavus with a few erect, pale, simple setae. Ventral surface: Mesosternum and abdomen with relatively long, semierect, simple setae. Legs: Entire length of hind tibial posterior face with two dense rows of short erect setae.

Male genitalia: Aperture. Left paramere (Fig. 234): Apical half stout, elongate, trunk-like with a flared, truncate apex; base stout with two thickened, apically rounded processes. Right paramere (Fig. 236): Mainstem thickened, apically rounded, with a short, thick, upturned lateral process at middle. Phallotheca (Fig. 235): Stout on basal half, narrowing apically into a slender, recurved hook and a deeply toothed, subapical area.

Female: Unknown.

Etymology.

This species is named in honor of the late mirid specialist Dr. Leonard A. Kelton (retired from the Biosystematics Research Institute, Agriculture Canada, Ottawa), friend, colleague, and collector of all known specimens of this species, as well as numerous other specimens used in this study.

Distribution.

Durango, Mexico.

Host.

One of the type specimens was taken from mistletoe growing on pine.
