Dimensions: TW, 0.47–0.49; HL and PW, 0.30–0.32; MW, 0.48– 0.51; AWIV, 0.64–0.66; ANW, 0.22–0.24; TL, 1.48–1.55.

Male (6). Gula with 4–6 setae on each side. Metanotum with 10–13 marginal setae; metasternal plate with 7–10 setae. Tergal setae, without median gap in rows: I, 20–25; II, 25–32; III, 29–34; IV, 26–35; V, 31–38; VI, 27–33; VII, 24–28; VIII, 17–21.

Genital sac sclerite as in Fig. 24 , rounded apically without subapical projections. Dimensions: TW, 0.43; HL, 0.28–0.30; PW, 0.27–0.29; MW, 0.36–0.39; AWIV, 0.48–0.51; GL, 0.40–0.43; TL, 1.22–1.26.

Type material. Holotype female ( USNM), ex A. aurantiirostris , COSTA RICA: Puntarenas, Monte Anivo Lodge, 13 km N Portero Grande, 20 Mar 1995, Fisher #2122. Paratypes, all ex type host: 4 females, 5 males ( USNM), same data as holotype; 1 female, 1 male ( OSU), Limon Prov., Pandora, 28 Apr 1964, O-2639.

Remarks. The uninterrupted rows of tergal setae along with the number of setae on the metanotum, the metasternal plate, and tergites I and VII–VIII will differentiate females of M. aurantiirostris from others of the group. Males are recognized by their number of setae on the abdominal tergites and sternites.
