Diagnosis. Cyrtocapsus glabratus ( Figs. 27, 28 ) is recognized by the relatively small size; uniformly dark dorsum; yellowish-white antenna, with segment I infuscated at the base; dorsally dark head, with the undersurface yellowish white; shiny, impunctate, glabrous calli; dark brown middle and hind coxae; entirely dark brown hind femur; and dark brown hind tibia, with only the apex pale.

This species keys to couplet 6 with the similar but the much larger C. schaffneri ( Figs. 52–54 ), based on the fuscous femora, at least on the apical thirds, and the dark brown middle and hind coxae. These species also share a dorsally dark and ventrally white head, long labium extending at least to the middle coxae, the shiny, impunctate, glabrous calli, and having all the femora at least partially dark brown. Cyrtocapsus glabratus is separated by the smaller size (2.85–2.94 mm versus 3.72–4.08 mm), the entirely dark brown hind femur (versus dark on apical two thirds with dorsal and ventral surfaces frequently pale), and the parameres ( Figs. 73, 74 ), especially the right paramere ( Fig. 74 ).

Description. Male ( Figs. 27, 28 ) (n = 2, plus holotype measurements in parentheses): Length to apex of membrane 2.91–2.94 mm (2.85 mm), length to base of cuneus 1.95–1.98 mm (1.89 mm), widest width across hemelytra 1.04–1.06 mm (1.01 mm). Head: Width 0.69–0.70 mm (0.67 mm), interocular width 0.30–0.34 mm (0.32 mm). Labium: Length 0.74–0.75 mm (0.74 mm, bent). Antenna: Segment I length 0.26–0.29 mm (0.27 mm); II, 0.45–0.46 mm (0.45 mm); III, 0.34–0.35 mm (missing); IV (missing). Pronotum: Median length 0.69 mm (0.67 mm), basal width 0.98 mm (0.96 mm).

Coloration: Head yellowish brown, vertex with a transverse fuscous line, frons with narrow transverse lines on either side of middle that connect posteriorly; clypeus dark brown on sides, pale brown dorsally; sides dark brown, undersurface uniformly pale yellowish white; eyes dark brown to dark reddish brown. Labium yellowish white; labrum dark brown. Antennal segment I yellowish white, with base narrowly grayish brown; segment II–IV yellowish white. Pronotum, scutellum, and hemelytron uniformly black; membrane translucent, veins and inside of areole fuscous. Ventral surface of thorax black; abdomen dark brown to fuscous. Middle and hind coxae dark brown, with bases paler, front coxa pale yellowish white; hind femur uniformly dark brown, including base; middle femur dark brown on apical two thirds, pale on basal third; front femur dark brown dorsally on apical third, pale on sides and most of ventral surface; middle and hind tibiae dark brown with apices pale, front tibia uniformly dark brown.

Texture and Vestiture: Head shiny, impunctate, weakly rugose, with dense, short, silvery sericeous setae along base, inner margins of eyes, and median line. Pronotum shiny, disc evenly and finely punctate; calli weakly raised, impunctate, glabrous; anterior margin and quadrate borders around calli with dense, silvery, sericeous setae; disc with less dense, scattered, silvery sericeous setae. Scutellum with silvery, sericeous setae. Hemelytron dull, impunctate, with evenly scattered, short, silvery sericeous setae.

Female: Unknown.

Etymology. The specific epithet “ glabratus ” is used to denote the shiny, impunctate, and glabrous calli of this species.

Host. The type series was taken on Piper sp. [ Piperaceae ].

Distribution. Known only from Heredia Province, Costa Rica.
