Myrsidea citrinae Price and Dalgleish , new species

( Figs. 7–9 )

Type host. Sicalis citrina Pelzeln , Stripe-tailed Yellow Finch.

Female (6). Gula usually with 4, less often 3, setae on each side. Metanotum and dorsal abdomen as in Fig. 7 . Metanotum not enlarged, with 6 marginal setae; metasternal plate with 5–6 setae. Abdominal tergites of similar size, with only slight medioposterior convexity on II–IV or II–V. Tergal setae, with median gap in each row: I, 8–12; II–V, 10–14; VI–VII, 9–11; VIII, 8. Postspiracular setae very long on V–VI (0.14–0.23), extremely long on VII (>0.34). Sternal setae: II, 3–4 in each aster, 11–13 marginal between asters, 8–9 anterior; III, 20–22; IV–V, 26–31; VI, 24–27; VII, 9–14; VIII–IX, 19–23. Dimensions: TW, 0.42–0.44; HL, 0.29– 0.32; PW, 0.26–0.29; MW, 0.40–0.42; AWIV, 0.53–0.58; ANW, 0.18–0.20; TL, 1.36–1.49.

Male (7). Gula with 4, much less often 3, setae on each side. Metanotum and dorsal abdomen as in Fig. 8 . Metanotum with 6 marginal setae; metasternal plate with 5–6 setae. Tergal setae, with median gap in each row: I, 6–8; II, 8–12; III–V, 10–12; VI–VII, 8–11; VIII, 8–9. Sternal setae: II, 3–4 in each aster, 9–12 marginal between asters, 8–10 anterior ( Fig. 9 ); III, 14–19; IV, 21–25; V, 23–28; VI, 21–25; VII, 10–13; VIII, 4. Genital sac sclerite as for M. campestris . Dimensions: TW, 0.39–0.40; HL, 0.27–0.30; PW, 0.23–0.25; MW, 0.33– 0.35; AWIV, 0.42–0.45; GL, 0.38–0.40; TL, 1.12–1.20.

Type material. Holotype female ( USNM), ex S. citrina , VENEZUELA: Edo. Bolivar, 60 km E Sta. Elena, Jan 1987, R.C. Dalgleish. Paratypes ( USNM): 5 females, 9 males, same data as holotype.

Remarks. The female of M. citrinae is differentiated from others of the group by having only six marginal metanotal setae, a definite median gap in the tergal rows, extremely long postspiracular setae on tergite VII, and an unmodified tergite I. The male is separated by the small number of setae on the metanotal margin and on tergites VII–VIII and sternites VII–VIII. Additionally, both sexes have at least four longer medioanterior setae on sternite II.
