Diagnosis. Cyrtocapsus intermedius ( Fig. 34 ) is recognized by the overall dark brown color, with the corium all or in part paler brown; the yellowish- to reddish-brown embolium; the pale yellowish-white antenna, with the apex of segment II red to reddish brown; the mostly fuscous cuneus; and the pale yellow to yellowish-white legs.

It is most similar to C. fiuzai ( Figs. 25, 26 ) in overall color, but the latter differs in having slightly more brownish orange along the posterior margin of the pronotum, a larger pale area at the apex of the corium, a more extensively brownish-orange cuneus with only the inner third dark, the uniformly yellowish-white antennal segment II lacking a red apex, and the broadly rounded right paramere ( Fig. 81 ).

Description. Male ( Fig. 34 ) (n = 3): Length to apex of membrane 3.42–3.68 mm, length to base of cuneus 2.40–2.46 mm, widest width across hemelytra 1.40–1.46 mm. Head: Width 0.74–0.83 mm, interocular width 0.34– 0.40 mm. Labium: Length 0.82–0.88 mm. Antenna: Segment I length 0.45–0.46 mm; II, 0.72–0.75 mm; III and IV missing. Pronotum: Median length 0.90–0.96 mm, basal width 1.17–1.28 mm.

Coloration: Head dorsally fuscous on vertex, dark brown on clypeus, and yellowish orange laterally, ventrally, and along inner margins of eyes; eyes reddish brown. Labium yellow to yellowish brown, apex of segment IV darker brown. Antenna uniformly pale yellow, with apex of segment II red or reddish brown. Pronotum fuscous to dark brown, discal area becoming slightly paler brown. Scutellum fuscous to black. Hemelytron with clavus dark brown, corium dark brown with apical area paler brown to almost entirely pale brown in lectotype, and embolium pale brown to reddish brown; membrane clear to translucent, veins brown, inside of areole smoky brown. Legs, including coxae, pale yellow; tarsomere III and claws brown.

Texture and vestiture: Head rugose, weakly transversely striate, with silvery, sericeous setae, especially along midline and inner margins of eyes. Pronotum shiny, disc and collar coarsely punctate; calli prominent, finely punctate, separated by a deep pit; collar and calli with dense silvery, sericeous setae, disc with finer, more sparse, silvery sericeous setae. Scutellum evenly and finely punctate, with dense silvery sericeous setae. Hemelytron dull, impunctate, with scattered silvery sericeous setae.

Male genitalia: Left paramere ( Fig. 80 ) with basal stem slender, main body broadened, then narrowing to a sharp hook apically. Right paramere ( Fig. 81 ) with a slender stem, elongate main body, and bluntly rounded apex.

Female (n = 3, plus lectotype measurements in parentheses): Length to apex of membrane (n = 2) 3.36–3.52 mm (3.23 mm), length to base of cuneus 2.34–2.40 mm (2.27 mm), widest width across hemelytra 1.44–1.54 mm (1.44 mm). Head: Width 0.74–0.77 mm (0.77 mm), interocular width 0.37–0.38 mm (0.37 mm). Labium: Length 0.80–0.83 mm (0.80 mm). Antenna: Segment I length (n = 1) 0.45 mm (0.43 mm); II, (n = 1) 0.50 mm (0.51 mm); III missing (shriveled); IV missing (missing). Pronotum: Median length 0.90–0.91 mm (0.88 mm), basal width 1.20–1.25 mm (1.20 mm).

Host. Unknown.

Distribution. Cyrtocapsus intermedius was described from Trinidad ( Reuter 1909) and later reported from Suriname ( Carvalho & Rosas 1965) and Venezuela ( Carvalho & Afonso 1977, Cazorla-Perfetti 2021). With the synonymy of C. xinguanus , the distribution of C. intermedius is extended to Mato Grosso, Brazil. Bahia is a new Brazilian state record.

Discussion. Study of the lectotype of C. intermedius , designated below, and the holotype images and original description of C. xinguanus shows that these two taxa are conspecific.

Type designation. Because Reuter (1909) did not indicate how many specimens he had when describing C. intermedius , for nomenclatural stability, I am designating the following female in the USNM collection as the lectotype: Label 1, “ Trinidad, WI, 6–26–02, Chipman”; 2, “ O. Heidemann collector”; 3, “(hand written) “21”; 4, “Spec. type”; 5, “ Cyrtocapsus intermedius n. sp. O. M. Reuter det.”; 6 (red), “Type No. 61881 USNM”; 7 (red, here added), “ LECTOTYPE: ♀ Cyrtocapsus intermedius Reuter , desig. by T.J. Henry. ”

Other type material examined. Holotype ♂ (images of Cyrtocapsus xinguanus ): BRAZIL: “[Brasil], Confluencia, Xingu Kuluene, Matto [sic] Grosso, 6–47, J. C. M. Carvalho ” (destroyed in 2018 MNRJ fire).

Other specimens examined. BRAZIL: Bahia : 1 ♂, 1 ♀, Bahia, Bon Fim , Nov. 1907 [no collector] ( USNM) . SURINAME: 1 ♂, Paramaribo, 15–20 May 1970, N. Niesser ( USNM) . TRINIDAD: 1 ♂ (head missing) , 1 ♀, Dept. Agr. grounds, Port-of-Spain, Trinidad , 24–31 Oct. 1918, H. Morrison ( USNM) ; 1 ♀, Port-of-Spain, Trinidad, W.I. (no date), H.J. Crew ( USNM) ; 1 ♀, Caroni River , 12 Oct. 1918, H. Morrison ( USNM) ; 1 ♀, Cocoa Estate, about 6 mi. from La Brea, Trinidad , 18 Oct. 1918, H. Morrison ( USNM) .
