Rhinotus purpureus (Pocock, 1894)

( Figs. 2C , 4F , 5 E-F)

Descriptive notes: See Mauriès (1980: 1101, fig. 62) and Wesener (2014: 588, figs. 1-2, for the synonym P.malagassum ).

Identification: Native species of Polyzoniida in Brazil belong to the genera Siphonotus Brandt, 1837 and Burinia Attems, 1926 ( Hoffman, 1977, 1980; Enghoff et al., 2015). Males of R. purpureus are recognized by having sternite of anterior gonopod with two lobes carrying long setae; coxae with trichostele carrying long setae; third podomere laterally with short setae and carrying mesally a protruding channel ( Mauriès, 1980: fig. 62; Wesener, 2014:fig. 2a; Fig. 5E ).Posterior gonopod sternite elongat- ed into two lobes; each one with apical setae; remaining podemeres partly fused and difficult to distinguish; tarsus elongated and apically with short claw ( Wesener, 2014: fig. 2b; Fig. 5F ).

Distribution: The range extension of R. purpureus is not known and its native area is still uncertain ( Hoffman, 1999). The species has been recorded in the Neotropical region ( Shelley, 1998c),West Africa, Mauritius, East Indies ( Hoffman, 1999), Madagascar ( Wesener, 2014), and Asia ( Hoffman, 1977; Korsós, 2004). In Brazil, the species has been recorded in urban areas from Manaus and from uncertain localities in the state of Amazonas (see Hoffman et al., 1996, 2002).
