Udamopyga diversa Lopes, 1940: 948. Type locality: Brazil, Rio de Janeiro. References. Dodge (1965; key); Lopes (1969a; catalog); Lopes (1973; biological notes); Lopes (1988; key); Pape (1996; catalog); Mello-Patiu et al. (2009; checklist).
Type-material examined. HOLOTYPE ♂: “ Rio de Janeiro / H. S. Lopes [printed on white paper, black frame]” // [EX] “Ins. Osw. Cruz [Instituto Oswaldo Cruz] / Cult. [culture] N° 28 [printed on white paper]” // [EX] “Ins. Osw. Cruz [Instituto Oswaldo Cruz] / N° 10358 [number in microscope slide collection] [printed on white paper]” // “ Holotype [printed on red paper, black frame]” // “ Udamopyga / diversa / Lopes / Lopes Det. [printed on white paper, black frame]” // “ MNRJ / 2293 [printed vertically on white paper]” (MNRJ) [holotype in good condition; terminalia not dissected; puparium pinned with specimen; obtained in culture from a female from Meier, Rio de Janeiro, RJ, 18.ii.1932].
PARATYPES. 1 ♂, 2 ♀♀ (one allotype): same data as holotype (MNRJ); 1 ♂: BRAZIL, RJ, Rio de Janeiro, Jardim Botânico, vi.1934, culture 152, H. S. Lopes leg. (MNRJ) [paratypes in good condition; ♂ from culture 28 is double-mounted with left wing, left anterior and mid legs missing; the abdomen was previously on microscope slide N° 10367, but Canada balsam was removed and the terminalia are now preserved in glycerin in a plastic microvial; allotype ♀ double-mounted, with left wing and left leg detached and glued to label; terminalia not dissected; other ♀ with mid leg detached and glued on label, with abdomen on microscope slide N° 13613; tergites missing].
Additional material examined. Brazil: 1 ♂, Espírito Santo, Linhares, vi.1972, P.C. Elias leg. (MNRJ); 1 ♀, Espírito Santo, Guarapari, 23.i.1973, culture 1099, H.S. Lopes leg. (MNRJ); 1 ♂, 1 ♀, Espírito Santo, Guarapari, 9.ii.1973 H.S. Lopes leg. (MNRJ); 1 ♂, Rio de Janeiro, Rio de Janeiro, Grajaú, i.1957, H.S. Lopes leg. (MNRJ).
Diagnosis. Male cercus with a tuft of long and hair-like setae in cercal base (Figs 19–20, 46); vesica with conspicuous lateroventral spinose ornamentation and inner ventral margin as two spinose projections (Figs 21–22); juxta formed of two well-individualized sub-rectangular lobes (Figs 21–22). Female T6 convex along midline, without a longitudinal crease (Fig. 52); ST5 wider than long; ST7 about 2x as long as ST6, with a concave area near middle, ST8 membranous and indistinct; epiproct membranous, with two pairs of setae.
Redescription. Differs from U. squamata sp. nov. as follows:
Male (n = 8). Length: 9–14 mm; frons about 0.28x head width at level of ocellar triangle; dorsocentral setae 3+3; T5 with a row of 12 marginal setae; ST5 with a short median window and arm with a conspicuously broad and rounded apex (Fig. 18); cercal base with a tuft of long, hair-like setae; cercal prong narrow in distal third (posterior view), with apex beveled and slightly curved anteriorly in lateral view (Figs 19–20, 46); surstylus with numerous setae along anterior margin (Fig. 19); pregonite approximately the same length as postgonite, with spatulate apex and a slight concavity along dorsal margin (Fig. 21); postgonite with a poorly-developed median dilatation on anterior margin, where the long seta is inserted (Fig. 21); hypandrium and phallapodeme sub-equal in size (Fig. 21); vesica with a conspicuous lateroventral spinose ornamentation and inner ventral margin as two spinose projections (Figs 21–22); juxta formed of two sub-rectangular lobes (lateral view) and joined ventrally just at base (Figs 21–22); lateral and median styli with distinct apical spines; base of median stylus broader (Fig. 22).
Female (n = 5). Length: 10–14 mm; frons about 0.36x head width at level of ocellar triangle; ST4 with two pairs of long setae; ST5 wider than long; T6 convex along midline, without a longitudinal crease (Fig. 52); ST7 about 2x length of ST6, with concave area near middle; ST8 membranous and indistinct; epiproct with one pair of setae (Lopes 1940: figs 33–34).
Distribution. Brazil (Espírito Santo *, Rio de Janeiro).
Remarks. Udamopyga diversa is morphologically similar to Udamopyga squamata sp. nov. (see remarks under that species). However, males of U. diversa have cercal base with a conspicuous tuft of hair-like setae and vesica formed of two rounded lobes with some spinose ornamentation, similarly to U. malacophila and U. neivai (Figs 19–26, 28–30, 46–48). Udamopyga diversa can be differentiated from these species by the following features: dorsocentral setae 3+3, apex of male cercal prongs clearly separated and slightly divergent in posterior view (Fig. 20), female T6 convex along midline, and female epiproct with one pair of setae (Fig. 52). Udamopyga malacophila has 3+4 dorsocentral setae, apex of male cercal prongs separated but parallel and close to each other (Figs 23, 47), juxta with a concave depression along apical margin (ventral view) (Fig. 26), female with T6 with a longitudinal crease along midline (Fig. 53) and epiproct without setae. Udamopyga neivai has 3+4 dorsocentral setae, apices of male cercal prongs fused along their entire length (Figs 28, 48), juxta with a slightly convex dilatation in the apical margin (ventral view) (Fig. 31), female with T6 with a strong longitudinal crease along midline (Fig. 54) and epiproct with two pairs of setae.
