Polyzonium malagassum de Saussure & Zehntner, 1902 Polyzonium malagassum de Saussure & Zehntner, 1902: 285 (first description) ' Polyzonium ' malagassum.��� Enghoff 2003: (list). Material examined. Type material: 1 M lectotype (designated herewith), 5 F paratypes (two missing the head), MNHN B019. Label data: Madagascar, Grandidier. No precise locality given. Label data fits the data mentioned in the first description 100 %. Additional material: 3 F, MHNG, ' Madagascar', Polyzonium malagassum, H. de Saussure det. 1903, newer label inside stating "after Hoffman Rhinotus ? africanus (Cook)" [another synonym of R. purpureus]. Redescription. The specimens are in very good condition, ca. 7 mm long with the male lectotype slightly smaller. The width is 0.78 mm in the largest female. The specimens have 38 (lectotype, 2 F paratypes) body rings plus telson. The colour is a faded dark brown with lighter antennae (Fig. 1 A). On each side of head with single, large black ocellus (Fig. 1 B). Collum overlapping head up to lower half of ocellus. Gonopods: Anterior gonopod sternite with two rounded lobes, each carrying a long seta (Fig. 2 A). Coxae fused and massive, with sutures still visible. Each coxa with a long trichostele, carrying a long seta. First podomere small but wide, second podomere massive, third podomere carrying mesally a protruding channel for the tarsus of the posterior gonopod (Fig. 2 A), as well as a partly covered process further laterally. Podomere 3 laterally with ca. 4 short setae. Posterior gonopod sternite elongated into two widely separated, rectangular lobes, each carrying 4 or 5 strong setae (Fig. 2 B). Above the syncoxite with three basal, partly fused and difficult to distinguish podomeres, apically with a very long, slender tarsus. Tarsus apically with a short claw (Fig. 2 B). P. malagassum, a new synonym of R. purpureus. As noted by Shelley (1998), R. purpureus is a widespread tramp species introduced to various pacific islands, West Africa, SE Asia, Middle America, the southern USA, several Seychelles islands as well as Madagascar. Individuals of R. purpureus were often described as new species, leading to more than a dozen species synonyms (Hoffman 1980), and generic synonyms such as Boninozonium Takakuwa, 1942; Orsilochus Attems, 1900; Paraburenia Verhoeff, 1939; and Paraconus Chamberlin, 1945. In fact, the Malagasy R. purpureus was already described as Orsilochus acuticonus more than a century ago (Attems 1910), and recently synonymized (Golovatch & Korsos 1992). Our illustrations of the gonopods of the lectotype of Polyzonium malagassum are virtually identical with those illustrated by previous authors (Mauri��s 1980, Golovatch & Korsos 1992) and clearly show that P. malagassum represents another synonym of R. purpureus.
