Myrsidea sinaloae Price and Dalgleish , new species

( Figs. 16–17 )

Type host. Melozone kieneri (Bonaparte) , Rusty-crowned Ground Sparrow.

Female (1). Gula with 5 setae on each side. Metanotum and dorsal abdomen as in Fig. 16 . Metanotum not enlarged, with 14 marginal setae; metasternal plate with 6 setae. Abdomen with tergite II medially enlarged and compressing III–IV. Tergal setae, with median gap in rows: I, 17; II–III, 13–14; IV–VI, 17; VII, 11; VIII, 8. Postspiracular setae long on V–VI (0.11–0.17), very long on VII (0.30). Sternal setae: II, 3–4 in each aster, 16 marginal between asters, 14 anterior; III, 25; IV–V, 33–34; VI, 27; VII, 16; VIII–IX, 22. Dimensions: TW, 0.46; HL, 0.32; PW, 0.30; MW, 0.47; AWIV, 0.67; ANW, 0.23; TL, 1.51.

Male (1). Gula with 5 setae on each side. Metanotum with 10 marginal setae; metasternal plate with 6 setae. Tergal setae, with median gap in rows: I–VI, 14–16; VII, 10; VIII, 8. Sternal setae: II, 4 in each aster, 11 marginal between asters, 10 anterior; III, 23; IV–V, 27–29; VI, 23; VII, 12; VIII, 5. Genital sac sclerite as in Fig. 17 , slightly distorted, but with prominent subapical projection on each side. Dimensions: TW, 0.42; HL and PW, 0.29; MW, 0.40; AWIV, 0.50; GL, 0.43; TL, 1.28.

Type material. Holotype female ( OSU), ex M. kieneri , MEXICO: Sinaloa, Santa Lucia, 30 July 1963, CLW-47. Paratype ( OSU): 1 male, same data as holotype.

Remarks. The female of M. sinaloae is unique in having the metanotum and tergite I normal and tergite II with a pronounced medioposterior convexity ( Fig. 16 ). The male is recognized by having 10 marginal metanotal setae in conjunction with the number of setae on tergites I and VII–VIII and sternites III and VII. Although described from only a female/male pair, the female tergal development clearly defines the species. The male is tenuously separated on the basis of quantitative abdominal chaetotaxy.

Etymology. This species is named for the Mexican state in which the type host was collected.
