Tinamotaecola wardi ; Marietto-Gonçalves et al. 2012: 208.

Type host. Cariama cristata (Linnaeus, 1758) , the red-legged seriema

Other host. Chunga burmeisteri (Hartlaub, 1860) , the black-legged seriema (see Remarks below).

Male: No specimen of this sex was available from Argentina or Chile for this study. However, we examined two males from Chunga burmeisteri from Paraguay and two males from Cariama cristata from Brazil, which agree well with measurements given by Hellenthal et al. (2002: 140). Body measurements: HL 0.618–0.636, POW 0.474–0.492, OW 0.559–0.561, PL 0.158–0.214, PW 0.364–0.370, PTL 0.246–0.258, PTW 0.536–0.545, AL 1.311–1.349, AW 0.765–0.794, GL 0.493–0.547, GW 0.141–0.151, TL 2.281–2.390.

Female: General habitus as in Fig. 13 View FIGURES 12 – 13 . Head as in Fig. 3 View FIGURES 1 – 3 . Metanotum with 10 posterior setae. Tergocentral setae: segment II 6, VII– V 10, VI 7, VII 8, VIII 4. Sternal setae: II 4, III 10, IV–VI 8, VII 4. Vulva with 15–17 long and 9–10 spiniform setae on each side (total 48–54) ( Fig. 18 View FIGURES 14 – 18 ). Body measurements: HL 0.654–0.696, POW 0.495–0.526, OW 0.538–0.609, PL 0.183–0.229, PW 0.337–0.401, PTL 0.221–0.268, PTW 0.462–0.621, AL 1.413–1.581, AW 0.808–0.929, TL 2.471–2.695

Specimens examined. Ex Chunga burmeisteri : 1♀, Rosario de la Frontera, Provincia Salta, Argentina, 20 Nov. 1904 (MLP); 2♂, Benjamín Aceval, Departamento Presidente Hayes, Paraguay, no date, F. Schade coll. (ACC).

Ex Cariama cristata : 2♂, 2♀ (topotypes from the type series, not originally designated), Franco da Rocha (23°20'S, 46°43'W), 723m, State of São Paulo, Brazil, Jul. 1949, M. Peña coll. (MZUSP # 1629–30); 1♂, 2♀, Botucatu, State of São Paulo, Brazil, 17 Aug. 2005, G.A. Marietto-Gonçalves coll. (MZUSP # 2407–08); 3♂, 2♀, Blumenau, State of Santa Catarina, Brazil, 2001, J.C. Souza Jr. coll. (MZUSP # 2888–89).

Remarks. Tinamotaecola wardi was originally described from specimens collected on Cariama cristata in Brazil. However, other louse samples from C. cristata collected in Argentina and Paraguay are T. zyskowskii . Based on the material available of Tinamotaecola wardi from Chunga burmeisteri , we believe that this bird is probably its regular host in northern Argentina and Paraguay. This scenario is similar to that of Bothriometopus macrocnemis (Burmeister, 1838) ( Ischnocera , Philopteridae sensu lato), a louse species that regularly parasitizes Anhima cornuta (Linnaeus, 1766) ( Anseriformes , Anhimidae ), but which has also been recorded on Chauna torquata (Oken, 1816) in some Brazilian localities. However, Chauna torquata is the regular host for B. simillimus (Giebel, 1874) (see Cicchino & Mey 2007: 53). We speculate that dispersal or recent host-switching of T. wardi from Chunga burmeisteri to Cariama cristata , or vice-versa, may have occurred, primarily in regions where both species of Cariamidae are or were sympatric, with a later spread of these hosts over other areas bearing the newly acquired louse species (see Johnson et al. 2003; Paterson et al. 1999; Brooks & Ferrao 2005; Hoberg & Brooks 2008). All known records of T. wardi from its two host species are shown in Fig. 20 View FIGURE 20 .
