Myrsidea marini Price and Dalgleish , new species

( Figs. 37–38 )

Type host. Pezopetes capitalis Cabanis , Large-footed Finch.

Female (1). Gula with 5 setae on each side. Metanotum and dorsoventral abdomen as in Fig. 37 . Metanotum enlarged, with circular posterior margin bearing 6 laterally-positioned setae; metasternal plate with 9 setae. Abdominal tergite I with pronounced medioposterior convexity and other tergites as shown. Tergal setae, with median gap in each row: I–II, 27; III–V, 24–25; VI, 22; VII–VIII, 19–20. Postspiracular setae long on V–VI (0.12–0.14), very long on VII (0.30). Sternal setae: II, 4 in each aster, 20 marginal between asters, 10 anterior; III, 28; IV–VI, 33–35; VII, 22; VIII–IX, 31. Dimensions: TW, 0.45; HL, 0.29; PW, 0.31; MW, 0.49; AWIV, 0.60; ANW, 0.21; TL, 1.56.

Male (1). Gula with 5 setae on each side. Metanotum with 10 marginal setae; metasternal plate with 10 setae. Tergal setae, without median gap in rows: I, 23; II, 25; III–VI, 22–24; VII, 25; VIII, 22. Sternal setae: II, 3 in each aster, 16 marginal between asters, 17 anterior ( Fig. 38 ); III, 31; IV–VI, 36–39; VII, 34; VIII, 25. Genital sac sclerite distorted, but appearing similar to Fig. 29 . Dimensions: TW, 0.42; HL and PW, 0.28; MW, 0.39; AWIV, 0.49; GL, 0.46; TL, 1.39.

Type material. Holotype female ( OSU), ex P. capitalis , COSTA RICA: San Jose, Empalme, Madre Selva, 9 Aug 1985, M.A. Marin. Paratype ( OSU): 1 male, same data as holotype.

Remarks. The broadly rounded metanotum and tergite I with a conspicuous medioposterior convexity set the female of M. marini apart from others of this group. The small number of marginal metanotal setae and the large number of setae on tergite I further support this separation. The very long postspiracular setae on tergite VII and the number of abdominal tergal and sternal setae will identify the male of M. marini .

Etymology. This species is named for M. A. Marin, Western Foundation of Vertebrate Zoology, Los Angeles, California, the collector of the bird yielding the lice described here.
