Diagnosis. Male cercus with numerous long setae of the same length on cercal base ( Figs 37–38 , 50 ); vesica formed of two blackish and sclerotized lobes with a cracked-looking integument and inner ventral margin as two long projections covered with microtrichia ( Figs 39–40 , 50 ); juxta formed of two lobes, well-individualized juxtal lobes with latero-anterior membranous projections ( Figs 39–40 , 50 ). Female T6 undivided and convex along midline, without a longitudinal crease, and with conspicuous golden setulae along apical margin ( Fig. 56 ); ST5 wider than long; ST7 about 3x as long as ST6, with a discal concavity near middle ( Fig. 56 ); ST8 membranous and not very distinct; epiproct membranous, with two pairs of setae.

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

Male (n = 8). Length: 8–13 mm; parafacial, fronto-orbital plate and posterior ocular orbits with golden pruinosity; frons about 0.22x head width at level of ocellar triangle; frontal vitta blackish along its whole length; 10–12 well-developed frontal setae reaching level of apex of pedicel; T5 with about 10 marginal setae and a set of long setae concentrated on ventral margin; cerci fused along their whole length and with apex truncate (posterior view), cercal prong blackish distally and with a small, anteriorly curved projection (lateral view) ( Figs 37–38 , 50 ); pregonite of similar length as postgonite, with a narrow apex, median projection and a weakly sclerotized area near apex in anterior margin ( Fig. 39 ); postgonite almost straight, with narrow base and a long seta inserted almost in the middle ( Fig. 39 ); basiphallus longer than distiphallus ( Fig. 39 ); vesica formed of lobes with a dark margin, with a cracked-looking integument; inner ventral margin of vesica as two elongated projections covered with microtrichia ( Figs 39–40 , 50 ); juxtal lobes with latero-anterior membranous projections ( Fig. 39 ); lateral stylus a bit shorter than median stylus ( Fig. 40 ).

Female (n = 2). Length: 10–13 mm; frons about 0.27x head width at level of ocellar triangle; 9 well-developed frontal setae; ST4 with two pairs of long setae; ST5 wider than long; T6 undivided and convex along midline, without a longitudinal crease and with conspicuous golden setulae along posterior margin ( Fig. 56 ); ST7 about 3x as long as ST6, with a discal concavity near middle ( Fig. 56 ); ST8 membranous and not very distinct; epiproct membranous, with two pairs of setae ( Lopes 1940: figs 35–36).

Distribution. Argentina (Misiones, Salta *); Brazil (Mato Grosso *, Rio de Janeiro, Rio Grande do Sul *, Santa Catarina).

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