Type information. Holotype male and allotype female ( FIOC). Type locality: Brazil, Rio de Janeiro, Teresopolis. Not examined.

Diagnosis. Known only from Brazil and Uruguay. Separable from C. nigribasis based on the reddish genal groove (black in C. nigribasis ); on the white rim and fringe of setae on the lower calypter (as in Fig. 3 ) (dark reddish brown in C. nigribasis , as in Fig. 4 ); male frons narrower, averaging 0.066 (0.06–0.07/5) (whereas averaging 0.102 (0.09–0.12/5) in C. nigribasis ); male surstylus and cercus slender ( Figs. 10, 11 ) (whereas shorter and more stout ( Figs 12, 13 ) in C. nigribasis ); ST5 normal ( Fig. 37 ) (exceptionally broad ( Fig. 38 ) in C. nigribasis ); female T5 without incision (T5 with incision in C. nigribasis ).

Description. Lower parafacial and genal groove reddish; upper parafacial and fronto-orbital plate with pale brown microtomentum as seen from above; parafacial darker as seen from below, with two changeable spots, the lower one faint; fronto-orbital plate black with one changeable spot on lower half in female; frontal vitta with upper portion black and lower portion reddish; pedicel brown to black, base of first flagellomere reddish, the color extending toward distal end on posterolateral sides, the remainder brown; genal dilation dark brown to black with silvery microtomentum; occiput with several rows of long dark occipital setae below postocular row, central occiput with silky silvery setae, less extensive than in C. nigribasis ; ocellar triangle small, anterior ocellus about 2x the diameter of the posterior ocelli; row of supravibrissal setae on facial ridge ascending about halfway to antennal base ( Fig. 5 ); only two postsutural intra-alar setae; lower calypter darker brown with pale rim and white fringe. Body length, males 9–10mm, females 10–11mm.

Male. Frons broad, at narrowest, 0.066 (0.06–0.07/5) of head width; 0.91 (0.91–0.92/5) of first flagellomere; parafacial at narrowest 1.6 (1.5–1.9/5) of frons; 1.44 (1.1–1.7/5) of first flagellomere; gena to eye ratio 0.57; frontal setae ascend to just below where fronto-orbital plates nearly meet; lateroclinate and proclinate setae absent; changeable spot on upper parafacial. Surstylus and cercus small and slender, surstylus longer than cercus ( Figs. 10, 11 ). Phallus with acrophallus unusually broad in dorsal view ( Figs. 18, 19 ); hypandrium, pre- and postgonites, ejaculatory sclerite and sternites as in Figs. 27 –29 , 37 .

Female. Frons 0.32 (0.31–0.33/5) of head width at narrowest; 4.1 (3.7–4.4/5) of first flagellomere; parafacial at narrowest 0.42 (0.40–0.45/5) of frons; 1.7 (1.5–1.9/5) of first flagellomere; gena to eye ratio 0.52 (0.50–0.54/5); frontal setae ascend to anterior ocellus, proclinate and lateroclinate setae present. A changeable spot midway on fronto-orbital plate and another on upper parafacial. T5 without incision, sometimes with a v-shaped notch. Ovipositor and spermathecae as in Figs.41 , 45 , posterior margin of ST8 bifurcated.

Specimens examined. 10 males, 11 females. Brazil (9 males, 4 females): Rio Grande do Sul, Pelotas, 1 male, Aug. 4, 1956, C. Biezanko (BMNH); 1 female, June 29, 1963, J. Lucia Mantovani-Biezanko (BMNH); 5 males, 3 females, Rio de Janeiro, Alto Itatiaia, 2000m, March, 1941, R.C. Shannon, B.L. Gomes (USNM); 1 male, Nova Teutonia, 27°11'S 52°23'W, Oct. 1966, Fritz Plaumann (CNC); 1 male, same data, except Sept. 25, 1960; 1 male, Cruzeiro, Dec., 1962, F. Plaumann (CNC). Uruguay (1 male, 7 females): 1 female, Montevideo, J. Tremoler, Nov. 25, 1924 (USNM); 1 male, 6 females, Soriano, Cardona, 33°52'60''S 57°22'60''W, March 20, 2008, T.L. Whitworth (TW).

Distribution. Brazil and Uruguay, Fig. 2 . Specimens from Uruguay were collected near the Argentinian bor- der, and it is therefore likely that C. lopesi also occurs in Argentina. The species possibly occurs in nearby Paraguay, and maybe in other countries in the region. Specimens were found from near sea level to about 2000m.
