Tinamotaecola n. sp. ; Cicchino & Castro 1998 : 121 . Type host. Tinamotis ingoufi Oustalet, 1890 , the Patagonian tinamou. Diagnosis. A member of the andinae species-group, distinguishable from the other two species in the group by its much smaller body measurements of the two sexes. Males are also distinguishable from T. elegans by having a greater number of sternal setae. Female chaetotaxy is very similar to that of T. elegans , but the vulvar margin has fewer setae (30 against 39–45). FIGURES 8–9. Tinamotaecola nanus : 8 , male; 9 , female. FIGURES 10–11. Tinamotaecola nanus : 10 , third nymphal instar (N III); 11, second nymphal instar (N II). Male: General habitus as in Fig. 8 . Metanotum with 10 setae. Paratergal setae: segments II–III 0, IV 1 , V 2 , VI–VIII 3. Tergal setae: II 9 , III 12 , IV 10, V 9 , VI 6 , VII 4 , VIII 2. Sternal setae: II 6 , III 8 , IV 8 , V 8 , VI 4. Genitalia similar to those of T. andinae , but consistently much smaller ( Fig. 15 ). Body measurements: HL 0.479, POW 0.379, OW 0.421, PL 0.189, PW 0.284, PTL 0.184, PTW 0.389, AL 0.842, AW 0.611, GL 0.374, GW 0.124, TL 1.642. Female: General habitus as in Fig. 9 . Metanotum with 10 setae. Paratergal setae: segments II–III 0, IV 1 , V–VIII 2. Tergal setae: II 9 , III 11 , IV 12, V 10 , VI 10, VIII 6 , VIII 4. Sternal setae: II 6 , III 8 , IV 10 , V–VI 8. Vulva with 11–12 long and 7 short spiniform setae on each side (total 36–38). Body measurements: HL 0.556, POW 0.433, OW 0.500, PL 0.211, PW 0.322, PTL 0.222, PTW 0.478, AL 1.211, AW 0.778, TL 2.133. Nymph III: General habitus as in Fig. 10 . Metanotum with 10 (5+5) posterior setae. Body measurements: HL 0.467, POW 0.360, OW 0.427, PL 0.173, PW 0.133, PTL 0.173, PTW 0.360, AL 0.653, AW 0.467, TL 1.533. Nymph II: General habitus as in Fig. 11 . Metanotum with 8 (4+4) posterior setae. Body measurements: HL 0.400, POW 0.307, OW 0.347, PL 0.133, PW 0.107, PTL 0.160, PTW 0.380, AL 0.547, AW 0.400, TL 1.160. Etymology. the species epithet “ nanus ” (Latin = dwarf) refers to the small size of this species, being the smallest among all known Tinamotaecola species. Specimens examined. Ex Tinamotis ingoufi : Holotype ♂, 1♀ paratype , 3 N II, 2 N III, Tellier, Departamento Deseado, Provincia Santa Cruz, Argentina , 20 Sep. 1962 (MLP). Remarks. This species was mentioned by Ward (1957: 350) as a possible new species and Cicchino & Castro (1998: 121) noted the presence of this undescribed taxon in Argentina . Yet, Hellenthal et al. (2002) did not mention this undescribed taxon. The type locality, superimposed on the host geographical range is shown in Fig. 20 .
