Ribautia ducalis Pereira, Minelli & Barbieri, 1995

Ribautia (Ribautia) ducalis Pereira, Minelli & Barbieri 1995 , Amazoniana 13 (3–4): 325, 329–331, figs. 46–87

The species was hitherto known only from the type locality: Brazil: Amazonas: Reserva Florestal A. Ducke. In addition to further material from the same site, we have recently identified material from another locality: Brazil: Amazonas: Manaus: INPA (secondary upland forest, unburned), Kempson soil extraction, (03º 08'S 60º 01' W), 25.9.1985, J. Adis et al. leg.: 2 ΨΨ with mature ova, 45 p. l., b.l. 13 and 14 mm; 2 ɗɗ with tubula seminifera full of mature spermatozoa, 43 p. l., b.l. 12 and 13 mm (MLP); ibid., 24.4.1986: 1 Ψ with mature ova, 45 p. l., b.l. 14 mm; 2 ɗɗ juveniles (with 2+2 coxal organs only), 43 p. l.,b.l.8and 9.5mm; 1juvenile (sex?),with1+1coxal organs only, 45 p. l.,b.l. 7.5mm (INPA).

The recently studied material includes specimens with number of leg pairs other than those recorded thus far, i.e. ɗɗ with 43 pairs of legs and ΨΨ with 45 pairs of legs.
