Myrsidea anoxanthi Price and Dalgleish   , new species

( Figs. 40–44 View FIGURES 37 – 44. 37 – 38 )

Type host. Loxipasser anoxanthus (Gosse)   , Yellow-shouldered Grassquit.

Female (7). Gula with 4–5 setae on each side. Close to M. serini   ( Fig. 39 View FIGURES 37 – 44. 37 – 38 ). Metanotum not enlarged, with 8–11 marginal setae; metasternal plate with 5–6 setae ( Fig. 41 View FIGURES 37 – 44. 37 – 38 ). Abdomen with tergites essentially unmodified. Tergal setae, with median gap only on posterior segments: I, 10–12; II, 14–16; III, 11–15; IV, 13–14; V, 11–13; VI, 11–12; VII, 8–10; VIII, 8–9. Postspiracular setae long on V –VI (0.12–0.17), extremely long on VII (0.30–0.37). Sternal setae: II, 3–4 in each aster, 11–13 marginal between asters, 8–12 anterior ( Fig. 41 View FIGURES 37 – 44. 37 – 38 ); III, 18–22; IV –V, 27–37; VI, 20–31; VII, 16–18; VIII –IX, 14–17. Dimensions: TW, 0.34–0.37; HL, 0.25–0.27; PW, 0.23–0.26; MW, 0.36–0.41; AWIV, 0.51–0.54; ANW, 0.17–0.19; TL, 1.26–1.34.

Male (4). Gula with 4–5 sete on each side. Metanotum and dorsal abdomen as in Fig. 42 View FIGURES 37 – 44. 37 – 38 . Metanotum with 10 marginal setae; metasternal plate with 5–6 setae. Tergal setae, with median gap only on posterior segments: I, 11–13; II, 15–17; III –V, 14–18; VI, 12–14; VII, 12–13, VIII, 9–11. Sternal setae: II, 3–4 in each aster, 11–13 marginal between asters, 9–10 anterior ( Fig. 43 View FIGURES 37 – 44. 37 – 38 ); III, 19–22; IV –V, 24–31; VI, 22–26; VII, 17–18; VIII, 6–9. Dimensions: TW, 0.33–0.34; HL, 0.23–0.25; PW, 0.22–0.23; MW, 0.31–0.33; AWIV, 0.39–0.43; GL, 0.35– 0.37; TL, 1.05–1.10.

Type material. Holotype female ( USNM), ex L. anoxanthus   , JAMAICA: Marshall's Pen, Mandeville, Feb 1982, R.C. Dalgleish. Paratypes ( USNM): 2 females, 3 males, same data as holotype.

Other material. 4 females, 1 male, ex Sporophila minuta   (L.), Ruddy-breasted Seedeater, VENEZU- ELA (1 collection).

Remarks. Both sexes of M. anoxanthi   are consistently smaller than those of M. serini   , generally being at or below the lowest values of the ranges given by Klockenhoff (1984). Also, the females of this new species tend to have fewer abdominal setae, especially on the anterior tergites and sternites. Males are not as clearly separated by these quantitative data, but the metanotal margin of M. anoxanthi   has only 10 setae versus 11–15 for M. serini   . These two species are clearly closely related, but the new species quantitatively is sufficiently distinct to justify its recognition.
