Myrsidea campestris Price and Dalgleish , new species

( Figs. 1–6 )

Type host. Euneornis campestris (L.), Orangequit.

Female (10). Gula with 4 setae on each side, rarely one side with 5. Metanotum and dorsoventral abdomen as in Fig. 6 . Metanotum much enlarged, posterior margin evenly rounded, with 18–22 setae; metasternal plate with 6–7 setae. Anterior abdominal tergites II–V medially compressed by enlarged metanotum and tergite I. Tergal setae, with median gap in each row: I, 11–15; II, 18–21; III–IV, 20–24; V, 16–21; VI, 15–18; VII, 12–15; VIII, 11–13. Postspiracular setae subequally long on V–VI (0.12–0.18), and much shorter on VII (0.06–0.09). Sternal setae: II, 4 in each aster, 15–18 marginal between asters, 5–6 anterior; III, 18–21; IV–V, 26–37; VI, 23–30; VII, 12–15; VIII–IX, 17–23. Dimensions: TW, 0.40–0.43; HL, 0.29–0.31; PW, 0.26–0.28; MW, 0.41–0.45; AWIV, 0.51–0.59; ANW, 0.19–0.20; TL, 1.31–1.45.

Male (9). As in Fig. 1 . Gula with 4 setae on each side. Metanotum with 11–14 marginal setae; metasternal plate with 5–6 setae. Tergal setae, with median gap in each row: I, 8–11; II–IV, 12–17; V, 11–14; VI, 10–12; VII, 8–10; VIII, 8–9. Postspiracular setae long on V–VI (0.10–0.12), longer on VII (0.15–0.22). Sternal setae: II, 4 in each aster, 12–17 marginal between asters, 5–7 anterior ( Fig. 2 ); III, 13–19; IV, 20–25; V, 24–29; VI, 21–26; VII, 10–14; VIII, 4–6. Genital sac sclerite as in Fig. 3 , with very small subapical projection on each side. Dimensions: TW, 0.37–0.38; HL, 0.27–0.28; PW, 0.23–0.24; MW, 0.32–0.35; AWIV, 0.40–0.43; GL, 0.37–0.39; TL, 1.11–1.20.

Type material. Holotype female ( USNM), ex E. campestris , JAMAICA: Marshall's Pen, Mandeville, Feb 1982, R.C. Dalgleish. Paratypes ( USNM): 9 females, 9 males, same data as holotype.

Remarks. This species is easily distinguished from others of the group by the female with the large posteriorly rounded metanotum bearing at least 18 marginal setae and the unusually short postspiracular setae on tergite VII. Both sexes have only five to seven anterior setae on sternite II, including one to three longer medioanterior setae. The male is further recognized by the numbers of abdominal tergal and sternal setae and its small dimensions.
