Diagnosis. Male cercus with a conspicuous tuft of long and hair-like setae on cercal base (Figs 28–29, 48); vesica formed of two rounded lobes (lateral view) and with inner ventral margin as spinose projections (Figs 30– 31, 48); juxta formed of two long lobes, each with a slightly convex dilatation on distal margin (ventral view) (Figs 30–31, 48). Female T6 with longitudinal crease along midline (Fig. 54); ST5 longer than wide; ST6–8 fused; ST7 about 2x as long as ST6, with a discal concavity near apex (Fig. 54); ST8 membranous and indistinct, epiproct membranous, with two pairs of setae.

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

Male (n = 6). Length: 10–15 mm; parafacial, fronto-orbital plate and posterior ocular orbits with golden pruinosity; frons about 0.24x head width at level of ocellar triangle; frontal vitta entirely dark brownentire; 7–10 well-developed frontal setae reaching level of apex of pedicel; gena and genal groove dark brown with golden pruinosity; postgena black with golden pruinosity and whitish setae; antenna dark brown; 9–12 meral setae; T4 with two or three pairs of lateral marginal setae; T5 with 12 marginal setae; ST5 with sharp-pointed arms and window as long as wide (Fig. 27); cerci fused along their whole length (posterior view); cercal prong distally narrowed with apex slightly rounded in lateral view and straight in posterior view (Figs 28–29, 48); surstylus robust with narrowed base and enlarged apex with setae anteriorly, covered with microtrichia in proximal half (Figs 28, 48); pregonite sub-equal in size to postgonite, with narrow and curved apex (Figs 30, 48); postgonite with long seta near apex (Fig. 30); hypandrium of approximately the same length as phallapodeme; distiphallus longer and wider than basiphallus (Fig. 30); inner ventral margin of vesica with two long, sclerotized, spinose projections (Figs 30–31); juxta formed of two long and well-individualized lobes, narrow in lateral view and broad in ventral view, each with a slightly convex dilatation on distal margin (ventral view) (Figs 30–31, 48); median stylus short and almost straight, with margin serrated in apical half (Fig. 31); lateral stylus arched, slightly longer than median stylus and with a distinct row of spines (Fig. 31).

Female (n = 9). Length: 11–14 mm; frons about 0.23x head width at level of ocellar triangle; ST2 with three pairs of long setae; ST3–5 each with one pair of long setae; ST5 longer than wide; ST7 about 2x as long as ST6, with a discal concavity near apex (Fig. 54); ST8 membranous and not very distinct; epiproct membranous, with two pairs of setae (Lopes 1940: figs 29–30).

Distribution. Brazil (Ceará, Rio de Janeiro).

Remarks. Udamopyga neivai is morphologically similar to U. diversa and U. malacophila; see remarks under U. diversa . Lopes (1975a) pointed out differences between populations from the Brazilian states of Ceará and Rio de Janeiro (type-locality), especially related to some color variation; however, our comparative study did not show significant differences in the terminalia of both sexes.
