(Figs. 1–27)

Female (fig. 2): habitus as in fig. 2. Head slightly wider than long (cephalic index 1.09-1.10). Tergocentral setae: metathorax 6, tergites II–VIII 6, IX-X with 6–7 small and 14–17 very long setae, II–VIII flanked with 1–3 (usually 2) minute setae on each side. Abdominal sternal setae: II 4–6, III–VI 7–9, VIII 14–20 (a set of 4–7 minute setae located in the middle, flanked by 3–7 long setae each side), subgenital plate with 8–10 anterior and 5–8 posterior setae, brush of II with 1–5 short, brush of III with 7–9 short and spiniform setae. Anal fringe with 41–50 dorsal and 34–37 ventral setae (fig. 20). Measurements (n = 9): HL 0.289–0.294 (0.292 ± 0.03), HW 0.313–0.328 (0.319 ± 0.006), PW 0.250–0.275 (0.263 ± 0.009), MTW 0.470–0.588 (0.508 ± 0.041), AL 0.946–1.093 (1.005 ± 0.005), AW 0.676–0.053 (0.729 ± 0.063), TL 1.703–2.004 (1.785 ± 0.114). Cephalic index (n=9) 1.081–1.117 (1.093 ± 0.014).
Male: (fig. 4): Head slightly wider than long (CI = 1.06). Tergocentral setae: meso-and metathorax 6, tergites II–VIII 6, IX–X with 5–6 short setae each side (fig. 4), being II–VII flanked by 0–1 small seta on each side. Abdominal sternal setae: II 4, III–IV 8, V–VI 6, VII–VIII 4. Genitalia: basal plate not widened towards the basis of paramere. Parameres not widened at their base, tapering gradually from middle to apex, and endophallus with larger spiculae concentrated near the ostium (fig. 6). Body measurements (n = 1): HL 0.245, HW 0.260, PW 0.220, MTW 0.350, AL 0.670, AW 0.530, GL 0.275, GW 0.085, TL 1.150.
Third nymphal instar (figs. 7, 8, 13 and 14). Female: head almost as long as wide (CI = 1.01); gular plate with 3+3 unequal setae (fig. 27); thorax and abdomen as in figs. 7–8. Abdominal tergal setae: II–VIII much as for adult female except for their length, IX with 17–18 setae (fig. 13), II–VIII flanked with one small seta on each side. Abdominal sternal setae: II–VI with 4 medium long setae, VII with 4 long and 1 small inner seta on each side, VIII with 5 medium to long setae on each side, brush of II with 0–1 and III with 5 small setae, anal fringe with 18 dorsal and 16–17 ventral setae (fig. 14). Body measurements: HL 0.278–0.289 (0.279 ± 0.009), HW 0.267–0.289 (0.282 ± 0.013), AL 0.582–0.600 (0.590 ± 0.009), TL 1.182–1.311 (l.260 ± 0.069). Male third instar unavailable.
Second nymphal instar (figs. 9–12 and 15–18): Gular chaetotaxy 2+2 (or 2+1) (fig. 26). Head almost as long as wide (cephalic index = 0.98). Female individual: pro-, meso- and metathoracic chaetotaxy as for female N III. Tergocentral setae essentially as for female N III, except for IX–X bearing six long setae each side (fig. 15), and lacking of small seta flanking tergites II–VIII. Abdominal sternal setae: II–VII with 4 (rarely 3) sternocentral setae, II–VI flanked by 0–3 small setae each side, VIII with 3–4 medium to long setae each side, anal fringe with 8 dorsal and 10 ventral setae (fig. 16). HL 0.267, HW 0.260, AL 0.489, TL l.067. Probable male individual: thoracic and abdominal setae much as for female N II (figs. 17–18), except for tergite IX with 8 short setae (fig.17) and anal fringe with 5 dorsal and 6 small setae (figs. 17–18). Body measurements: HL 0.249, HW 0.244, AL 0.478, TL 1.015.
Type host. Zenaida auriculata virgata Bertoni, 1901.
Specimens examined. From Z. a. virgata: female HOLOTYPE and 9 female paratypes, 3 female nymphs III, 1 female nymph II, 1 male nymph II from Baradero, Partido de Baradero, Buenos Aires Province, I-1983, A.C. Cicchino; 1 female, 1 male paratypes from La Plata, Buenos Aires Province, ARGENTINA, 16-I-1983, A.C. Cicchino.
Additional specimens. From. Z. a. auriculata (Des Murs, 1847): 8 females, Chillán, Ñuble Province, CHILE, XII-2004, D. González-Acuña (in absence of males, these specimens are not designated as paratypes).
Remarks. Females are readily separable from all other species by cephalic index and body measurements, except B. beieri, from which it differs by having consistently larger head measurements (see Table I). If the male genitaliae of B. columbae and B. concii are very similar one another as atated by Złotorzycka (1976: 23) prove to be similar, then the genitalia of B. zenaidae n. sp. differs greatly from both, in shape of the basal plate and the parameres, as well as being also smaller (see figs. 5–6). Female specimens from Z. a. auriculata are morphologically undistinguishable from those of Z. a. virgate, so both “populations” probably be conspecific. However, the true identity of other Bonomiella species recorded from other Zenaida species deserve more careful studies, because they may involve some misidentifications (e. g. Emerson (1972), Conti & Forrester (1981), Galloway & Palma (2008), non identification (Di Mare 2003) or even cases of straggling or contaminations.
