sp. nov.

Myrsidea contopi Price, Hellenthal and Dalgleish , new species ( Figs. 13–14 View FIGURES 9 – 17. 9 – 10 )

Type host. Contopus cinereus (Spix) , Tropical Pewee.

Female. Dorsal thorax and abdomen as in Fig. 14 View FIGURES 9 – 17. 9 – 10 . Metanotum with 10–11 marginal setae. Tergites I–II or I–III with slight medioposterior convexity. Tergal setae: I, 8–10; II, 13–14; III, 15–17; IV, 14–15; V–VI, 11–13; VII–VIII, 8. Postspiracular setae on III and V–VI shorter than very long postspiracular setae on adjacent segments. Sternal setae: II, each aster with 4, less often 3, setae, 24 other setae; III, 19–21; IV, 30–32; V, 34–35; VI, 30; VII, 12–14; VIII–IX of subgenital plate, 22–25. Anus with 35–36 setae in dorsal fringe, 32–37 in ventral. Dimensions: TW, 0.43–0.44; HL, 0.31–0.32; PW, 0.27–0.28; PSL, 0.09–0.10; MW, 0.42–0.43; MSL, 0.14; AWIV, 0.56–0.58; ANW, 0.20–0.21; TL, 1.32–1.37.

Male. Metanotum with 9–10 marginal setae. Tergal setae: I, 7–8; II–III, 11–15; IV, 10–14; V, 10–12; VI, 10; VII, 8–10; VIII, 8. Sternal setae: II, each aster with 4, less often 3, setae, 18–22 other setae; III, 17–20; IV, 23–29; V, 28–30; VI, 22–27; VII, 13–16; VIII, 6–7. Genital sac sclerite 0.08 long, as in Fig. 13 View FIGURES 9 – 17. 9 – 10 , with pronounced distal asymmetry. Dimensions: TW, 0.40–0.41; HL, 0.27–0.30; PW, 0.24–0.27; PSL, 0.09–0.10; MW, 0.36– 0.37; MSL, 0.12–0.13; AWIV, 0.45–0.46; GL, 0.42–0.43; TL, 1.18–1.23.

Type material. Holotype male ( NMNH), ex C. cinereus , TRINIDAD: Sangre Grande, Melajo Forest, 21 Feb 1956, W. G. Downs, TRVL 109. Paratypes ( NMNH): 2 females, 5 males, same data as holotype.

Remarks. The male is readily recognized from all others of this group by its unique genital sac sclerite ( Fig. 13 View FIGURES 9 – 17. 9 – 10 ). The female only is tenuously separable from other species in the group by chaetotaxy and dimensions.
