Type host. Hypsipetes borbonicus (J. R. Forster) .

Male (3). Close to M. ochracei, differing as follows. Sternal setae: III, 12–14. Genitalia as in Fig. 4, but with genital sac sclerite as in Fig. 13. Dimensions: TW, 0.44–0.46; HL, 0.31–0.32; LSVII, 0.10–0.13; TL, 1.33–1.37; GL, 0.39–0.42; GSW, 0.036.

Female (5). Close to M. ochracei, differing as follows. Tergal setae: III, 19–23; IV, 20–26; V, 19–21; VI, 17–20; VII, 13–17; VIII, 15–18. Sternal setae: III, 22–27; VIII, 24– 32. Dimensions: TW, 0.49–0.53; HL, 0.33–0.35; PW, 0.31–0.33; MW, 0.46–0.50; AWIV, 0.64–0.70; TL, 1.65–1.77.

Type material. Ex H. borbonicus, the Olivaceous Bulbul, holotype male, Tokomoko, REUNION, 15 Mar. 1981, N. Barré. Paratypes, all ex H. borbonicus in REUNION: 2 males, 2 females, same as holotype; 3 females, same except 15 Aug. 1981.

Remarks. While both sexes of M. borbonici are morphologically close to those of M. ochracei, they may be separated by the unique male genital sac sclerite and the female with larger dimensions and more tergal and sternal setae.
