Zootaxa 2007 1467 1 18 Price and Dalgleish Price and Dalgleish [151,650,1487,1513] Insecta Menoponidae Myrsidea Animalia Phthiraptera 9 10 Arthropoda species conirostris sp. nov.    Typehost.  Arremonops conirostris(Bonaparte), Black-striped Sparrow.   Female (2).Gula with 4–6 setae on each side. Metanotum and dorsal abdomen as in Fig. 34. Metanotum not enlarged, with 12 marginal setae; metasternal plate with 6 setae. Abdominal tergites I–II largest, with I–IV or I–V having slight medioposterior convexity. Tergal setae, with median gap at least in rows on I–V: I, 16– 20; II, 19–22; III, 16–20; IV, 18–25; V–VI, 18–27; VII, 19–23; VIII, 14–19. Postspiracular setae long on V– VI (0.13–0.15), very long on VII (0.22–0.23). Sternal setae: II, 4 ineach aster, 20–24 marginal between asters, 13 anterior; III, 27–36; IV, 33–42; V, 37–50; VI, 32–39; VII, 13–17; VIII–IX, 21–32. Dimensions: TW, 0.48– 0.52; HL, 0.33–0.35; PW, 0.32–0.34; MW, 0.48–0.52; AWIV, 0.68; ANW, 0.23–0.26; TL, 1.66–1.68.  Male (2).Gula with 4–5 setae on each side. Metanotum with 8–10 marginal setae; metasternal plate with 6 setae. Tergal setae, with small median gap on I–III to I–VII: I, 15; II, 16–17; III–V, 18–22; VI, 19–25; VII, 18–22; VIII, 16–17. Postspiracular setae on VI very long (0.18–0.25), much longer than on V and near length of setae on VII. Sternal setae: II, 3–4 ineach aster, 18–20 marginal between asters, 11–13 anterior; III, 23–25; IV, 29–31; V–VI, 30–34; VII, 17–22; VIII, 10 ( Fig. 36). Genital sac sclerite as in Fig. 35, with slight indentation at apex and with small lateral subapical projection on each side. Dimensions: TW, 0.42–0.43; HL, 0.30– 0.31; PW, 0.28–0.30; MW, 0.38; AWIV, 0.48–0.50; GL, 0.43; TL, 1.28–1.29.    Typematerial. Holotypefemale ( OSU), ex  A. conirostris,  PANAMA: PanamaProv., Pacora, 5 June 1966, G.M. Lab. Paratypes, all from typehost: 1 male( OSU), same data as holotype; 1 female, 1 male( USNM),  COSTA RICA:Hacienda Baru, Dominical Puntarenus, 1 Ju1y 1993, Fisher & J.S. #735.   Remarks.The female of  M. conirostris, with tergites I–II similar in size and shape, resembles  M. zonotriciae, a member of the  campestrisspecies group. The number of setae on tergites I–II clearly separates these. The male of  M. conirostrisis unusual in having longer postspiracular setae on tergite VI, much longer than on V and nearly as long as on VII. This separation is further supported by the numbers of tergal and sternal setae.
