Diagnosis. This species ( Fig. 17 ) is readily distinguished by the brownish-orange head with only the middle of the frons and vertex darkened, the uniformly black pronotum, the black hemelytron with the embolium and apex of the corium bordering the cuneus contrastingly brownish orange, the translucent white membrane with only the veins brown, and the basally pale and apically brown hind tibia.

Cyrtocapsus costalis keys to the first rung of couplet 21 based on the relatively large size, pale hind femora, the contrasting brownish-orange embolium, the black pronotum, and the distally brown hind tibia. The last two species [ C. fiuzai ( Figs. 25, 26 ) and C. intermedius ( Fig. 34 )] in the key resulting from the choice in the second rung of the couplet are separated by the smaller size, the pale hind tibia, and the dark brown rather than black pronotum, often with a paler posterior margin.

Description. Holotype male ( Fig. 17 ): Length to apex of membrane 4.32 mm, length to base of cuneus 3.08 mm, widest width across hemelytra 1.68 mm. Head: Width 0.85 mm, interocular width 0.43 mm. Labium: Imbedded in glue. Antenna: Segment I length 0.61 mm; II, 0.74 mm; III and IV missing. Pronotum: Median length 1.09 mm, basal width 1.41 mm.

Coloration: Head yellowish to brownish orange, middle of vertex fuscous; eyes dark reddish brown. Labium not observed; imbedded in glue. Antennal segments I and II pale yellow to pale yellowish white; segments III and IV missing. Pronotum and scutellum black. Hemelytron dull fuscous to black, with embolium and a distinct spot at apex of corium yellowish to brownish orange; cuneus fuscous to black, with narrow outer margin brownish orange; membrane translucent white, veins brown, area inside areole clear. Ventral surface largely obscured by glue; visible parts black. Coxae obscured in glue; remainder of legs pale yellow to yellowish white, with only the hind tibia brown on the apical half; tarsi and claws missing or imbedded in glue.

Texture and vestiture: Head weakly shiny, rugose, distinctly transversely striate on frons; with recumbent, silvery, sericeous setae. Pronotum shiny, disc coarsely punctate, punctures smaller on collar and calli; calli prominent, separated by a deep groove; collar and calli with dense, silvery, sericeous setae, disc with more scattered silvery, simple setae. Scutellum finely and evenly punctate. Hemelytron dull, impunctate, with numerous silvery sericeous setae.

Male genitalia: Not examined; unique male glued to card.

Female (n = 1): Length to apex of membrane 4.20 mm, length to base of cuneus 3.12 mm, widest width across hemelytra 1.68 mm. Head: Width 0.80 mm, interocular width 0.45 mm. Labium: Imbedded in glue. Antenna: Segment I length 0.59 mm; II, 0.70 mm; III and IV missing. Pronotum: Median length 1.12 mm, basal width 1.46 mm.

Etymology. The specific epithet “costalis” is used to denote the contrastingly pale brownish-orange embolium of this species.

Host. Unknown.

Distribution. Known only from Peru.

Discussion. Both specimens of this species are heavily glued to cards, making determination of the sex of the paratype difficult. My side-view examination of the ventrally flattened abdomen indicates the paratype probably is a female.

Type material. Holotype ♂: PERU: Callanga [no other locality data or collection date] ( FMNH) . Paratype: 1 ♀, same data as for holotype ( FMNH) .
