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.

Female: General habitus as in Fig. 5 . Mesosternum and metasternum with 2 setae each (less frequently 1). Metanotum with 9–11 posterior setae. Paratergal setae: segments II–III 0, IV 2–3, V 2, VI 3–4, VII–VIII 3. Tergal setae: II 7–9, III 8–13, IV 8– 14, V 8–13, VI 7– 12, VII 7–11, VIII 3–6.

Specimens examined. 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 .
