Myrsidea brunneinuchi Price and Dalgleish   , new species

( Figs. 26–30 View FIGURES 26 – 36. 26 – 30 )

Type host. Buarremon brunneinuchus (Lafresnaye)   , Chestnut-capped Brush Finch.

Female (4). Gula with 5–6 setae on each side. Metanotum and dorsal abdomen as in Fig. 30 View FIGURES 26 – 36. 26 – 30 . Metanotum not enlarged, with 14–16 marginal setae; metasternal plate with 11–13 setae. Abdominal tergites I –II enlarged, remainder smaller. Tergal setae, without median gap in rows: I, 16–19; II, 17–20; III, 24–29; IV, 29–33; V, 34– 40; VI, 33–36; VII, 35–39; VIII, 25–27. Postspiracular setae long on V –VI (0.12–0.22), very long on VII (0.27–0.28). Sternal setae: II, 4–5 in each aster, 19–22 marginal between asters, 27–31 anterior ( Fig. 28 View FIGURES 26 – 36. 26 – 30 ); III – IV, 31–38; V, 37–43; VI, 35–48; VII, 32–38; VIII –IX, 36–48. Dimensions: TW, 0.47–0.49; HL, 0.29–0.33; PW, 0.30–0.31; MW, 0.46–0.49; AWIV, 0.61–0.63; ANW, 0.22–0.24; TL, 1.48–1.53.

Male (5). Gula with 5–6 setae on each side. Metanotum with 15–20 marginal setae; metasternal plate with 10–12 setae ( Fig. 27 View FIGURES 26 – 36. 26 – 30 ). Tergal setae, without median gap in rows: I, 22–25; II, 26–27; III –VII, 28–34; VIII, 19– 24. Sternal setae: II, 4–5 in each aster, 18–21 marginal between asters, 24–30 anterior ( Fig. 27 View FIGURES 26 – 36. 26 – 30 ); III, 37–47; IV, 42–53; V, 44–59; VI, 49–51; VII, 42–46; VIII, 29–35 ( Fig. 26 View FIGURES 26 – 36. 26 – 30 ). Genital sac sclerite as in Fig. 29 View FIGURES 26 – 36. 26 – 30 , with slight apical indentation and no evident lateral subapical projections. Dimensions: TW, 0.44–0.45; HL, 0.29–0.32; PW, 0.27–0.29; MW, 0.37–0.39; AWIV, 0.46–0.51; GL, 0.41–0.42; TL, 1.28–1.34.

Type material. Holotype female ( USNM), ex B. brunneinuchus   , COSTA RICA: San José Prov., Los Chiquites, Tres Rios Reservoir, 3 May 1995, Fisher & J.S. # 2151. Paratypes ( USNM), all from type host: 1 male, same data as holotype; 3 females, same except 17 May 1995, Fisher & J.S. # 2205; 5 males, VENEZU- ELA: Trujillo, Bocono, 1 Mar 1986, R.C. Dalgleish.

Remarks. Both sexes of M. brunneinuchi   have no median gap in the tergal setal rows and are separated from others of the group by a much more abundant abdominal chaetotaxy. This is best shown by such a large number of setae on female tergites VII –VIII and male sternites II –III and VIII.
