Type-material examined. HOLOTYPE ♂: “225 [culture] [handwritten on white paper]” // [EX] “Col. Ins. O. Cruz [Collection Instituto Oswaldo Cruz] / N. 10045 [number of microscope slide] [printed on white paper]” // “ Holotype [printed on red paper, black frame]” // “ Udamopyga / malacophila / Lopes / Lopes Det. [printed on white paper, black frame]” // “MNRJ / 2295 [printed vertically on white paper]” (MNRJ) [holotype with abdomen dissected, terminalia on miscroscope slide; culture 225 was obtained from larvae bred from the gastropod Thaumastus taunaysi (de Férussac) (Bulimulidae) in Brazil, RJ, Rio de Janeiro, Grajaú, 16.x.1937, by H. S. Lopes].
PARATYPES: 1 ♀ (allotype): same data as holotype except microscope slide N o 10046 (MNRJ); 1 ♂: Brazil, RJ, Rio de Janeiro, Grajaú, culture 227, 22.ix.1937, H.S. Lopes leg. (MNRJ); 1 ♀: same data as previous except culture 230 and terminalia on microscope slide N o 13614; 1 ♀: same data as ♂ paratype except culture 260, 22.vi.1939, and terminalia mounted on microscope slide N o 13614 (MNRJ) [paratypes in good condition; ♂ with terminalia glued to culture label; one ♀ with abdomen somewhat crushed].
Additional material examined. Brazil: 2 ♂♂, 2 ♀♀: Espírito Santo, Linhares, vi.1972, P.C. Elias leg. (MNRJ); 1 ♂, Rio de Janeiro, Rio de Janeiro, Grajaú, xi.1937, H.S. Lopes leg. (MNRJ).
Diagnosis. Male cercus with conspicuous long setae on cercal base (Figs 23–24, 47); vesica formed of two rounded lobes with strong spinose ventral ornamentation and inner ventral margin with long spinose projections (Figs 25–26); juxta formed of two long lobes, each with a concave depression on distal margin (Figs 25–26). Female T6 with longitudinal crease along midline and roof-like appearance (Fig. 53); ST5 longer than wide; ST6– 8 fused, ST7 about 2x as long as ST6, with a concave area near apex; ST8 membranous and indistinct; epiproct membranous, without setae.
Redescription. Differs from U. squamata sp. nov. as follows:
Male (n = 5). Length: 10– 5 mm; parafacial, fronto-orbital plate, posterior ocular orbits and gena with golden pruinosity; frons about 0.23x head width at level of ocellar triangle; frontal vitta entirely dark brown; antenna with first flagellomere approximately 4x as long as pedicel; T4 with 3–4 lateral marginal setae; T5 with a row of 16 marginal setae and numerous long setae on the ventral face; ST5 arms with rounded apex [ST5 not dissected, so other features not visible]; cercus with numerous short apical setae besides long basal setae; cercal base slightly inclined posteriorly in lateral view and cercal prongs separated but parallel and close to each other in posterior view (Figs 23–24, 47); surstylus boomerang-like with numerous anterior setae (Fig. 23, 47); pregonite with a broad base, with apical half almost straight and apex slightly rounded, and with some setulae along posterior margin (Figs 25, 47); postgonite with base broader than slightly curved apex, with a long seta in basal half accompanied by several setulae (Figs 25, 47); vesica with proximal spinose ornamentation in ventral region and along inner ventral margin, and with two long, sclerotized, spinose projections (Figs 25–26); juxta formed of two elongated and well individualized lobes, each with concave depression on distal margin (ventral view) (Fig. 26); lateral stylus narrow and elongated, with a row of lateral spines along apical half; median stylus with rounded base and numerous apical spines (Fig. 26).
Female (n = 5). Length: 9–13 mm; 5–7 well-developed frontal setae; T5 with 12 marginal setae; ST2 with one pair of long setae; ST4 with two pairs of long setae; ST5 longer than wide; terminalia yellowish-brown; T6 undivided, dorsally narrow, with a longitudinal crease along midline (Fig. 53); ST5 longer than wide; ST6–8 fused; ST7 about 2x as long as ST6, with a concave area near apex; ST8 membranous and little distinct; epiproct membranous without setae (Lopes 1940: figs 25–26).
Distribution. Brazil (Espírito Santo *, Góias, Rio de Janeiro, Santa Catarina).
Remarks. Udamopyga malacophila is morphologically similar to U. diversa and U. neivai. See remarks under U. diversa.
