Tinamotaecola andinae ; Hellenthal et al. 2002: 137, figs 2, 5, 9. Tinamotaecola andinae ; Price et al. 2003: 244.

Type host. Tinamotis pentlandii Vigors, 1837 , the puna tinamou.

Other host. Chunga burmeisteri (Hartlaub, 1860) , the black-legged seriema (fide Hellenthal et al. 2002: 137), but see Remarks below.

Diagnosis. Amember of the andinae species-group, distinguishable from the remaining two species by larger body measurements, and a tendency to have a larger number of sternal setae in both sexes. Also males have more tergal setae and larger genitalia (GL 0.430–0.460 against 0.373–0.422 in T. elegans ) ( Fig. 14 ).

Male: General habitus as in Fig. 1 . Chaetotaxy: metanotum with 10 postero-marginal setae. Paratergal setae: segments II–III 0, IV–V 2, VI–VIII 3. Tergal setae: II 7–11, III 10– 12, IV 9–13, V 8– 12, VI 7, VII 4–6, VIII 2–4. Sternal setae: II 6–7, III 7–10, IV 7–9, V 6–8, VI 4–7, VII 2. Genitalia as in Fig. 14 . Measurements: HL 0.565–0.610; POW 0.430–0.440; OW 0.465–0.543; PL 0.157–0.225; PW 0.301–0.381; PTL 0.211–0.270; PTW 0.362–0.505; AL 0.900–1.257; AW 0.650–0.680; GL 0.430–0.490; GW 0.125–0.146; TL 1.850–2.276. Female: Metanotal and paratergal setae as for male. Tergal setae: II 4, III 8, IV 8 V 9, VI 9. Sternal setae: II 6, III 8, IV–V 10, VI 9, VII 6. Measurements: HL 0.630–0.670; POW 0.475–0.497; OW 0.540–0.563; PL 0.188–0.247; PW 0.338–0.350; PTL 0.227–0.285; PTW 0.457–0.490; AL 1.356–1.460; AW 0.810–0.819; TL 2.347–2.466.

Specimens examined. Ex Tinamotis pentlandii : 2♂, 1♀, Distrito Susques, Provincia Jujuy, Argentina, 8 Oct. 1986, J. Fernández (MLP, ACC). 1♂, Visviri, Provincia Tarapacá, Primera Región, Chile, 23 Sep. 2004, D.G. González-Acuña (UNCC). 1♂, 2♀, Potosí [19°35'S, 65°45'W, 4020m], Bolivia, 23 Jan. 1938, M.A. Carriker Jr (MZUSP #677).

Remarks. Dimensions and chaetotaxy of the specimens examined fall well within the ranges given by Hellenthal et al. (2002: 137). This species has been described from Bolivia by Carriker (1944: 87), and subsequently cited for Perú, Paraguay and Chile by Hellenthal et al. (2002: 137). Its probable presence in Argentina was pointed out by Cicchino & Castro (1998: 121) and is confirmed here. Hellenthal et al. (2002: 137) also examined specimens from Chunga burmeisteri from Brazil and Paraguay, suspecting that the host-louse association was incorrect. Considering that the geographical ranges of Tinamotis pentlandii and C. burmeisteri do not overlap, i.e. these hosts are allopatric ( Fig. 20 ), the probability of a natural host-switch by Tinamotaecola andinae from T. pentlandii onto Chunga is extremely low. Misidentification of the hosts or mislabelling of the samples examined by Hellenthal et al. (2002) are more likely explanations for that unexpected host-louse association (see also remarks under T. wardi below). All known locality records of Tinamotaecola andinae from T. pentlandii are shown in Fig. 20 .
