Diagnosis. Male cercus with a tuft of long setae on cercal base (Figs 42–43, 51); vesica formed of two concave lobes with striated ornamentation and inner ventral margin as two spinose projections (Figs 4–6, 44–45, 51); juxta with two lobes, each with lateral margin turned backward near base in lateral view (Figs 4–6, 44–45). Female T6 undivided and convex along midline, without a longitudinal crease (Fig. 57); ST5 wider than long; ST7 about 3x as long as ST6, with a discal concavity near middle (Fig. 57); ST8 membranous and not very distinct; epiproct membranous, with two or three pairs of setae.

Redescription. Differs from U. squamata sp. nov. as follows:

Male (n = 10). Length: 9–15 mm; parafacial, fronto-orbital plate and postocular orbits with golden pruinosity; frons about 0.24x head width at level of ocellar triangle; 7–9 well-developed frontal setae reaching level of apex of pedicel; gena and genal groove with pale golden pruinosity; 10–12 meral setae; T5 with 12 marginal setae; ST5 with rounded arms and a short window with numerous setulae (Figs 41, 51); terminalia reddish-brown; cercal prong narrow in distal third (posterior view), blackish apically and projected anteriorly (lateral view) (Figs 42–43, 51); surstylus long, of similar length as cercus, with a very narrow base and numerous setae along anterior margin (Figs 42, 51); pregonite with a long, weakly sclerotized median projection (Fig. 44); postgonite straight with rounded apex and a long seta near apex (Fig. 44); basiphallus longer than distiphallus (Fig. 44); vesica formed of two concave lobes with striated ornamentation and inner ventral margin as two spinose projections (Figs 4–6, 44– 45, 51); juxta with two lobes, each medially projected in distal margin (ventral and dorsal views) and with lateral margin turned backward near base (lateral view) (Figs 4–6, 44–45, 51); lateral stylus narrow with a laterally elongated base and small spines in distal half; median stylus with a spinose apex (Figs 5, 45).

Female (n = 7). Length: 9–13 mm. Differs from male as follows: frons about 0.35x head width at level of ocellar triangle; T6 convex along midline dorsally, without a longitudinal crease (Fig. 57); ST2–3 with one pair of long setae; ST5 wider than long; terminalia yellowish brown; ST7 about 3x as long as ST6, with a discal concavity near middle (Fig. 57); ST8 membranous and not very distinct; vaginal plate weakly sclerotized; epiproct membranous, with two or three pairs of setae (Lopes 1940: figs 27–28; as U. oglobini).

Distribution. Argentina (Corrientes, Misiones, Salta *); Brazil (Espírito Santo *, Góias, Mato Grosso *, Mato Grosso do Sul, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, São Paulo); Paraguay (Central*, Itapúa).

Remarks. Udamopyga setigena is morphologically similar to U. percita and U. provecta . See remarks under U. percita .
