Tinamotaecola elegans Hellenthal et al. 2002 : 138 , figs 6, 10. Tinamotaecola elegans ; Price et al. 2003 : 244 . Type host. Eudromia elegans elegans I. Geoffroy Saint-Hilaire, 1832 , the elegant crested-tinamou. Other hosts. Eudromia elegans albida (Wetmore, 1921) ; Eudromia elegans intermedia (Dabbene & Lillo, 1913) ; Eudromia elegans patagonica Conover, 1950 ; Eudromia formosa (Lillo, 1905) . Diagnosis. Amember of the andinae species-group and very close to T. andinae , but both sexes of T. elegans can be distinguished by their smaller dimensions and fewer sternal setae, and by males with a tendency to have fewer tergal setae. Male: General habitus as in Fig. 4 . Mesosternum and metasternum with 2 setae each. Metanotum with 10 posterior setae. Paratergal setae: segments II–III 0, IV 2 , V 1–2 , VI 3 , VII 2–3 , VIII 3. Tergal setae: II 6–8 , III 9–12 , IV–V 8– 11 , VI 6–7, VII 4–6 , VIII 2–5. Sternal setae: II 2 , III 4–6 , IV 5–7 , V 5–6 , VI 4–6 , VII 3–4. Male genitalia much as for T. andinae , but somewhat smaller.

Ex Eudromia elegans elegans : 3♂ , 1♀, Distrito General Alvarado, Otamendi, Provincia Buenos Aires, Argentina , 14 Sep. 2002 , A.C. Cicchino (ACC); 1♂ same data (MZUSP #2082); 1♂ , 1♀, Laguna Chasicó, Partido Villarino, Provincia Buenos Aires, Argentina , Feb. 1967 , A.C. Cicchino (MZUSP # 2084–85 ). Ex E. elegans patagonica : 1♂ , Faro Punta Delgada, Península Valdés, Distrito Viedma, Provincia Chubut, Argentina , 18 Jan. 1972 , A.C. Cicchino (ACC); 4♂ , 8♀, 8 N III, 1 N II, Lago Colhué Huapi, Distrito Sarmiento, Provincia Chubut, Argentina , 10 Nov. 1989 , A.C. Cicchino (ACC); 1♀, same data (MZUSP #2083); 2♂ , 1♀, Península Valdés, Distrito Viedma, Provincia Chubut, Argentina , 15 Feb. 2007 , D.G. González-Acuña (UNCC and ACC). Remarks. Ranges of male chaetotaxy in specimens examined by us fall within the upper limit or slightly exceed the ranges given by Hellenthal et al. (2002) , especially for tergites III–VI. A similar pattern applies to tergites III–VIII on females. Body measurements of both sexes are also around the upper limit of the ranges given by Hellenthal et al. (2002) . However, in the remaining features, our material agrees with those described by Hellenthal et al. (2002) . Tinamotaecola elegans was originally described from Argentinean specimens of three subspecies of E. elegans , and also from Eudromia formosa from both Argentina and Paraguay ( Hellenthal et al. 2002 : 139). Also, Cicchino & Castro (1998: 121) had previously noted the presence of this undescribed species from Argentina . To date, this Tinamotaecola species is confined to the two species of Eudromia . All known records of T. elegans from E. elegans are shown in Fig. 20 .
