 Description. Head yellowish brown, frontal triangle brown, interfrontal plates, gena, prementum, and antenna yellow, face brown with vertical yellow band below antenna, pollinose except interfrontal plates extending medially to lateral ocelli, and ventro-medial patch on face. Interfrontal setae in 3 pairs. Ocellar bristle just anterior to median ocellus. Anterior genal bristle about two-thirds length of vibrissa, subvibrissal bristle about 0.3X length of vibrissa.   
Thorax black, covered with microtomentum except anterior patch on ventral half of anepisternum and patch on katepisternum behind fore coxa. Microtomentum on scutum patterned, with apparent spots and stripes of silver or gold depending on viewing angle. Halter whitish, some brown below knob. Acrostichal setae in two rows. Proepisternum with 2 small setae.  
Foreleg with coxa and trochanter yellow, femur and tibia brown, anterior face of femur paler at base, tarsus yellowish brown. Mid leg with coxa dark brown, trochanter yellow, femur light brown, tibia and tarsus brown. Hind leg with coxa, trochanter, and distal 3 tarsomeres yellow, femur dark brown, tibia and basal 2 tarsomeres brown. Mid tibia with row of anterodorsal, 1 anteroventral, 1 posteroventral, 5 subapical bristles. Hind tibia with 1 anteroventral, 2 ventroapical bristles.  
Wing brown, white spots on crossveins r-m and dm-cu, at tips of R 2, R 2+3, R 4+5, and M, 1 on R 4+5 basal to r-m and 2 distal of r-m, 1 on CuA 1.   
Abdomen with tergites heavily sclerotized, black, entirely covered with microtomentum. Tergites not fused, syntergite 1+2 with posterior margin excavated. Sternites heavily sclerotized in both sexes, square, black, covered with microtomentum. Tergite 5 with a small depression medially on posteromedial margin.  
Male postabdomen: Sternite 5 slightly longer than wide, with posterolateral corners truncated, no anterior apodeme (Fig. 194). Surstylus long, slightly scooped. Postgonite with lobes widely separated, posterior lobe narrow, strongly curved, anterior lobe broad, rounded. Basiphallus long, with broad short epiphallus, short transparent preepiphallus. Distiphallus with long thin smooth dorsal tube, flanked by a single pair of spines, with a very long complex of transparent ventral sclerites (Fig. 191).  
Female postabdomen: Tergites 6–7 fully sclerotized, wider than long, with 2 weakly sclerotized posterior strips. Tergite 8 heavily sclerotized, shiny, with 3 posterior strips. Epiproct broad, with short anterior arms, pointed posteriorly, with 4 setae. Cerci with some microtomentum apically. Sternites 6–7 fully sclerotized, square, with 2 weakly sclerotized posterior strips. Sclerites of sternite 8 subrectangular, apical half covered with microtomentum. Hypoproct lozenge shaped, apical half covered with microtomentum and setae. Spermathecae about 1.75X longer than wide, basal half with annuli, without a sclerotized duct.  
 Type material. Holotype ♂: BRAZIL: Santa Catarina: Nova Teutônia, 27°10'S 52°22'W, 300–500 m, May 1963, F. Plaumann, debu01039261 (DEBU). Paratypes: same data as holotype but Nov 1962 (1 ♂, CNCI); as above but Jun 1973 (1 ♂, FMNH); as above but Sep 1972 (1 ♀, FMNH); as above but Nov 1978 (1 ♂, FMNH); Rio Grande do Sul: Pelotas, 3 Nov 1960, C. Biezanko (1 ♂, DEI).   
 Comments. The species name refers to the prominent vertical stripes on the face. This species is best identified by the combination of yellow fore and hind coxae and entirely black or brown femora.
