Type host. Thraupis cyanocephala (d’Orbigny and Lafresnaye) , Blue­capped Tanager.

Female (9). Metanotum and dorsal abdomen as in Fig. 5 . Metanotum much enlarged, with 8–10 marginal setae spread evenly along margin. Abdominal tergite I compressed by enlarged metanotum. Tergal setae: I, 28–34, all placed at posterior margin; II, 35–44; III, 38–44; IV, 36–43; V–VI, 33–42; VII, 27–31; VIII, 15–20. Postspiracular setae very long on IV, shortest on III and V–VII.

Dimensions: TW, 0.45–0.47; HL, 0.31–0.33; PW, 0.29– 0.31; MW, 0.45–0.48; AWIV, 0.59–0.66; ANW, 0.20–0.22; TL, 1.40–1.55.

Male (7). Metanotum and dorsal abdomen as in Fig. 6 . Metanotum with 8–10 marginal setae. Tergal setae: I, 25–30; II, 30–34; III–V, 31–38; VI, 29–34; VII, 26–29; VIII, 17–21. Sternal setae: II, 22–27; III, 23–26; IV, 25–33; V, 27–38; VI, 26–32; VII, 17–21; VIII, 8–11. Genital sac sclerite 0.080–0.090 long, as in Fig. 3 . Dimensions: TW, 0.41– 0.43; HL, 0.29–0.31; PW, 0.27–0.29; MW, 0.37–0.38; AWIV, 0.45–0.47; TL, 1.21–1.27.

Type material. Holotype female, ex T. cyanocephala , VENEZUELA: Bocono , Trujillo, 1 Mar 1986, R. C. Dalgleish . Paratypes: 6 females, 5 males, same data as holotype ; 1 female, 2 males, same except 2 Feb 1986; 1 female, same except 5 Mar 1986.

Remarks. The consistently larger number of tergal and sternal setae for both sexes of M. cyanocephalae easily distinguishes them from M. laciniaesternata , the only other known species from thraupids with the female having a much enlarged metanotum.
