Diagnosis. Male cercus with a conspicuous tuft of long and hair-like setae on cercal base ( Figs 28–29 View FIGURES 27–31 , 48 View FIGURES 46–51 ); vesica formed of two rounded lobes (lateral view) and with inner ventral margin as spinose projections ( Figs 30– 31 View FIGURES 27–31 , 48 View FIGURES 46–51 ); juxta formed of two long lobes, each with a slightly convex dilatation on distal margin (ventral view) ( Figs 30–31 View FIGURES 27–31 , 48 View FIGURES 46–51 ). Female T6 with longitudinal crease along midline ( Fig. 54 View FIGURES 52–57 ); ST5 longer than wide; ST6–8 fused; ST7 about 2x as long as ST6, with a discal concavity near apex ( Fig. 54 View FIGURES 52–57 ); 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 View FIGURES 27–31 ); 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 View FIGURES 27–31 , 48 View FIGURES 46–51 ); surstylus robust with narrowed base and enlarged apex with setae anteriorly, covered with microtrichia in proximal half ( Figs 28 View FIGURES 27–31 , 48 View FIGURES 46–51 ); pregonite sub-equal in size to postgonite, with narrow and curved apex ( Figs 30 View FIGURES 27–31 , 48 View FIGURES 46–51 ); postgonite with long seta near apex ( Fig. 30 View FIGURES 27–31 ); hypandrium of approximately the same length as phallapodeme; distiphallus longer and wider than basiphallus ( Fig. 30 View FIGURES 27–31 ); inner ventral margin of vesica with two long, sclerotized, spinose projections ( Figs 30–31 View FIGURES 27–31 ); 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 View FIGURES 27–31 , 48 View FIGURES 46–51 ); median stylus short and almost straight, with margin serrated in apical half ( Fig. 31 View FIGURES 27–31 ); lateral stylus arched, slightly longer than median stylus and with a distinct row of spines ( Fig. 31 View FIGURES 27–31 ).

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 View FIGURES 52–57 ); 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.
