( Figs. 18, 19 )

Diagnosis. This new species ( Figs. 18, 19 ) is recognized by the apically fuscous antennal segment I and black segment II, the centrally dark brown pronotum with wide paler brown lateral margins, pale legs with a fuscous streak on either side of the apical third of the hind femur, and a broad, mitt-shaped right paramere.

Cyrtocapsus discalis keys to couplet 11 with C. spatulatus ( Fig. 55 ) but the latter is readily distinguished by the uniformly black pronotum, pale yellowish-white hind femur, and broadly rounded right paramere ( Fig. 98 ).

Description. Holotype male ( Figs. 18, 19 ): Length to apex of membrane 3.36 mm, length to base of cuneus 2.43 mm, widest width across hemelytra 1.36 mm. Head: Width 0.80 mm, interocular width 0.46 mm. Labium: Length 0.82 mm. Antenna: Segment I length 0.48 mm; II, 0.61 mm; III, 0.48 mm; IV, 0.59 mm. Pronotum: Median length 0.88 mm, basal width 1.23 mm.

Coloration: Head with vertex, frons, and ventral surface fuscous, clypeus dark brown to fuscous, inner margins bordering eyes and sides yellowish brown to brownish orange; eyes reddish brown. Labium yellowish brown. Antennal segment I pale yellowish brown on basal half, dark brown apically; segment II fuscous, narrowly pale at base; segments III and IV fuscous. Pronotum with collar and calli fuscous to black; middle half of disc dark brown, yellowish brown laterally. Scutellum black. Hemelytron with clavus fuscous, corium fuscous with base, middle of apex, and embolium yellowish brown; membrane translucent, with veins and inside of areole fuscous. Ventral surface of thorax fuscous; abdomen dark brown to fuscous. Legs uniformly yellowish brown, except for a fuscous streak on outer apical fourth of hind femur and the slightly darker brown tarsomere III and claws of each leg.

Texture and vestiture: Head rugose, shiny, with silvery sericeous setae, especially along median line and inner margins of eyes. Pronotum shiny, disc and collar coarsely punctate, calli more finely and sparsely punctate and separated by a deep pit; collar and calli with dense silvery, sericeous setae, setae on disc finer and more scattered. Scutellum finely punctate, with dense silvery sericeous setae. Hemelytron shiny, impunctate, densely covered with silvery, sericeous setae basally, becoming finer posteriorly.

Male genitalia: Unique male not dissected. Right paramere elongate, with a short tubercle at broad base, and gradually tapering to a point distally.

Female: Unknown.

Etymology. The specific epithet “ discalis ,” is used to denote the dark central area of the pronotal disc, with wide yellowish-brown lateral margins.

Host. Unknown.

Distribution. Known only from Goiás state, Brazil.

Discussion. Although I have only one specimen of this new species, the color of the pronotum, antennal segment II, and hind femur unmistakably distinguish it from all other species of the genus.

Type material. Holotype ♂: BRAZIL: Corumbá de G[oiás], Brasil, 4–2–1962, J. & B. Bechyné ( USNM).
