Myrsidea taciturni Price and Dalgleish   , new species

( Figs. 18–22 View FIGURES 16 – 25. 16 – 17 )

Type host. Arremon taciturnus (Hermann)   , Pectoral Sparrow.

Female (7). Gula with 3–5 setae on each side. Metanotum and dorsoventral abdomen as in Fig. 22 View FIGURES 16 – 25. 16 – 17 . Metanotum not enlarged, with 12–15 marginal setae; posteriormost pair of peripheral anterior setae distinctly longer than anterior setae; metasternal plate with 6–8 setae. Abdomen with tergite I largest, with tapered convex posterior margin resulting in median compression of tergites II –VI. Tergal setae, with distinct median gap in rows: I, 12–16; II, 18–22; III –IV, 21–23; V –VI, 18–22; VII, 17–21; VIII, 15–19. Postspiracular setae long on V –VI (0.16–0.23), somewhat longer on VII (0.23–0.29). Sternal setae: II, 3–4 in each aster, 19–21 marginal between asters, 11–13 anterior ( Fig. 20 View FIGURES 16 – 25. 16 – 17 ); III, 26–31; IV, 34–40; V, 40–47; VI, 33–43; VII, 21–25; VIII – IX, 25–32. Dimensions: TW, 0.48–0.50; HL and PW, 0.31–0.33; MW, 0.46–0.49; AWIV, 0.65–0.68; ANW, 0.21–0.23; TL, 1.59–1.67.

Male (7). Gula with 4–5 setae on each side. Metanotum and dorsoventral abdomen as in Fig. 18 View FIGURES 16 – 25. 16 – 17 . Metanotum with 12–15 marginal setae; metasternal plate with 6–8 setae. Tergal setae, without median gap in rows: I, 15–18; II –V, 23–28; VI, 24–26; VII, 22–23; VIII, 17–21. Sternal setae: II, 3–4 in each aster, 17–20 marginal between asters, 12–13 anterior ( Fig. 19 View FIGURES 16 – 25. 16 – 17 ); III, 25–29; IV, 33–37; V, 37–43; VI, 35–39; VII, 25–29; VIII, 12–19. Genital sac sclerite as in Fig. 21 View FIGURES 16 – 25. 16 – 17 , with slight apical indentation and very small subapical projection on each side. Dimensions: TW, 0.43–0.45; HL and PW, 0.28–0.31; MW, 0.39–0.40; AWIV, 0.48–0.51; GL, 0.42–0.47; TL, 1.28–1.33.

Material. Holotype female ( USNM), ex A. taciturnus   , VENEZUELA: Edo. Bolivar, 60 km E Sta. Elena, Jan 1987, R.C. Dalgleish. Paratypes ( USNM): 7 females, 7 males, same data as holotype.

Remarks. The large number of marginal metanotal setae and setae on tergites VII –VIII, coupled with the enlargement and shape of tergite I, facilitate easy separation of females of M. taciturni   from others of the group. The male is identified by its number of metanotal and abdominal setae.
