Diagnosis. Male cercus with a tuft of long setae on cercal base (Figs 33–34, 49); vesica formed of two dark and sclerotized lobes with a convex, membranous and well-delimited central area, and with inner ventral margin as two double projections each consisting of two long, microtrichiose filaments (Figs 1–3, 35–36, 49); juxta formed of two well-individualized lobes with latero-posterior flaps (Figs 1–3, 35–36, 49). Female T6 convex along midline, without a longitudinal crease (Fig. 55); ST5 wider than long; ST7 about 3x as long as ST6 and with concave area near middle; ST8 poorly sclerotized; epiproct membranous, without setae.

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

Male (n = 23). Length: 10–13 mm; slightly golden pruinosity can be present on ocellar triangle; frons about 0.28x head width at level of ocellar triangle; 7–9 well-developed frontal setae reaching apex of pedicel; gena and genal groove with golden pruinosity; ST5 with apically-rounded arms and a short window; base of arms with a swollen area with numerous spiniform setae, apex of arms with long setae (Figs 32, 49); cerci fused along their whole length; cercal prong with truncate apex (posterior view) and with a small, anterior apical projection (lateral view) (Figs 33–34); surstylus boomerang-like with setae along anterior margin (Figs 33, 49); pregonite similar in length to postgonite, with base 3x as broad as median region (Fig. 35); postgonite almost straight with sharp apex and a long seta near apex (Fig. 35); hypandrium slightly longer than phallapodeme (Fig. 35); postgonal apodeme clavate (Fig. 35); vesica with blackish and sclerotized lobes with a central, convex, membranous and welldelimited area; inner ventral margin of vesica as two long, double projections, i.e., each composed of two filaments, both covered with microtrichia (Figs 1–3, 35–36, 49); juxta formed of two lobes with rounded lateroposterior flaps (Figs 1, 3, 35–36, 49); median stylus with spinose ornamentation in apical half (Fig. 36); lateral stylus slightly longer than median stylus, with a lateral row of spines (Fig. 36).

Female (n = 4). Length: 9–12 mm; frons about 0.31x head width at level of ocellar triangle; 5–7 welldeveloped frontal setae; T5 with about 16–18 marginal setae; ST4 with two pairs of long setae; ST5 wider than long; terminalia yellowish-brown; T6 convex along midline, without a longitudinal crease (Fig. 55); ST7 about 3x as long as ST6, with a concave area near middle; ST8 membranous and not very distinct; vaginal plate weakly sclerotized (Lopes 1940: figs 31–32).

Distribution. Argentina (Buenos Aires, Catamarca, Santiago del Estero, Tucumán); Brazil (Bahia *, Espírito Santo, Mato Grosso do Sul *, Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Sul *, São Paulo).

Remarks. Udamopyga percita is morphologically similar to U. provecta and U. setigena . In males of these three species the cercus has a sharp-pointed, anteriorly curved apex (Figs 33, 37, 42, 49–51) and the vesica is formed of conspicuously rounded lobes (Figs 1–6, 35–36, 39–40, 44–45, 49–51); in females T6 is convex along the midline and without a longitudinal crease (Figs 55–57). Males of Udamopyga percita and U. provecta also share juxtal lobes with lateral projections (Figs 1, 35, 39, 49–50) and vesica with a central membranous area (Figs 1–3, 35, 39, 49–50), while in U. setigena the juxtal lobes lack lateral projections (Figs 4, 44) and the vesica has striated ornamentation and no membranous central area (Figs 4, 44, 51). Udamopyga percita can be differentiated from U. provecta by the well-delimited membranous central area of the vesica and the rounded latero-posterior flaps of the juxtal lobes (Figs 1, 3, 35, 49), whereas in U. provecta the vesica has a cracked-looking integument, without a welldelimited central area, and the juxtal lobes have latero-anterior membranous projections (Figs 39, 50).
