( Figs. 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 )
Argizala brasiliensis Walke r, 1869: 60. type series: two females (syntype designed by John Huxley in 1972, Fig. 4 View FIGURE 4 ) deposited at British Museum of Natural History (BMNH), localities originally provided: " Brazil " and "Santarem". Epitype here designated (preserved in ethanol 85%): 1 male, labeled " Brazil, Rio Grande do Sul State, Capão do Leão Municipality, Universidade Federal de Pelotas (UFPel), 21.ii.2010, 31°48'01"S, 52°24'48" O (E. Zefa leg.)".
Diagnosis. (i) pronotum wider than longer ( Fig. 1 View FIGURE 1 A,D); (ii) distal margin of pseudepiphallic sclerite strongly concave ( Fig. 2 View FIGURE 2 A,B); (iii) longitudinal thin line not evidently sclerotized between pseudepiphallic sclerite and pseudepiphallic median lobe ( Fig. 2 View FIGURE 2 B,C*); (iv) endophallic central sclerite as wide as long, with short upper edge, not exceeding the median region of the lateral sclerites ( Fig. 2 View FIGURE 2 A); (v) endophallic lateral sclerites without apparent extensions on the external edges ( Fig. 2 View FIGURE 2 A); (vi) ectophallic apodeme extending parallel to the median region of the central endophallic sclerite, when presenting curvature toward ramis ( Fig. 2 View FIGURE 2 A,B).

Legs I and II with similar pattern: trochanter and coxa with light yellow spots ( Fig. 1 View FIGURE 1 C); femur light yellow in ventral portion, light brown in dorsal portion, with long black bristles associated to light yellow glabrous spots; tibia dark brown with some light yellow spots, and bristles similar to the femur; tibia I with two apical spurs ( Fig. 1 View FIGURE 1 F) and tibia II with three apical spurs ( Fig. 1 View FIGURE 1 G); oval tympanum present on outer face of tibia I ( Fig. 1 View FIGURE 1 E); first tarsomere light brown with a central ring light yellow; second tarsomere light brown; third tarsomere with light brown proximal portion, central portion light yellow, and distal portion dark brown. Leg III: femur from light yellow to light brown, presence of some black bristles associated to light yellow glabrous spots on dorsal portion ( Fig. 1 View FIGURE 1 A,B); tibia light yellow in ventral and lateral portions, light brown on dorsal portion; presence of four inner and outer dorsal spurs, being the more
proximal one on inner margin with specialized aspect, base black colored ( Fig. 1 View FIGURE 1 I,J); three inner and outer apical spurs unequal in length: the tree inner unequal in length with dorsal (id) longer than median (im) and ventral (iv) ( Fig. 1 View FIGURE 1 K), the three outer unequal in length with median (om) longer than dorsal (od) and ventral (ov) ( Fig. 1 View FIGURE 1 L); the inner and outer ventro-apical spurs unequal in length, the inner shorter than outer ( Fig. 1 View FIGURE 1 M); tarsomeres as in the legs I and II, except by the basitarsus with two apical spur, being the inner shorter than outer ( Fig. 1 View FIGURE 1 N); tarsal claws of all legs light brown. Abdomen: tergites dark brown ( Fig. 1 View FIGURE 1 B); sternites I–VIII with a transversal dark brown stripe in anterior margin and a dark brown spot associated to the lateral limits of the median third; third median of the sternites varying from light to dark yellow from the anterior to posterior sternites; supra-anal plate dark brown with posterior margin rounded ( Fig. 1 View FIGURE 1 O); subgenital plate light yellow with two longitudinal dark brown stripes in median portion, posterior margin with shallow concavity ( Fig. 1 View FIGURE 1 P); cerci light yellow to light brown.
Observations in non-epitype specimens—male genitalia: glabrous ( Fig. 2 View FIGURE 2 ); pseudepiphallic median lobe with a shallow invagination just below the pseudepiphallic parameres in ventral ( Fig. 2 View FIGURE 2 A) and lateral views ( Fig. 2 View FIGURE 2 C); pseudepiphallic median lobe greater than half length of the genitalia in lateral view ( Fig. 2 View FIGURE 2 C); pseudepiphallic sclerite completely covering dorsal portion of the genitalia ( Fig. 2 View FIGURE 2 B,C); apical lobe absent ( Fig. 2 View FIGURE 2 A,B,C); apex of ectophallic fold surpassing the apex of pseudepiphallic parameres ( Fig. 2 View FIGURE 2 A); ectophallic apodeme extending parallel to the median region of the central endophallic sclerite, when presenting curvature toward rami ( Fig. 2 View FIGURE 2 A,B — drawings); shell-shaped endophallus divided in three sclerites, one central and two laterals ( Fig. 2 View FIGURE 2 A); endophallic central sclerite as wide as long, with short upper edge, not exceeding the median region of the lateral sclerites ( Fig. 2 View FIGURE 2 A); endophallic lateral sclerites without apparent extensions on the external edges ( Fig. 2 View FIGURE 2 A).
