new species

Myrsidea olivacei Price, Hellenthal and Dalgleish  , new species ( Fig. 20View FIGURES 18 – 21. 18 – 19)

Type host. Mionectes olivaceus Lawrence  , Olive­striped Flycatcher.

Female. Dorsal thorax and dorsoventral abdomen as in Fig. 20View FIGURES 18 – 21. 18 – 19. Metanotum with 12 marginal setae. Tergite II with rounded medioposterior process, III –VI with median constriction, and I and VII –VIII normal. Tergal setae: I, 13; II –VI, 16–17; VII, 14; VIII, 10. Postspiracular setae on III and V –VII shortest, intermediate on I, and long to very long on II, IV, and VIII. Sternal setae: II, each aster with 4 setae, 24 other setae; III, 24; IV –VI, 28–31; VII, 13; VIII –IX of subgenital plate, 18; margin of subgenital plate with conspicuous well defined uniform spiculations ( Fig. 20View FIGURES 18 – 21. 18 – 19). Anus with 36–37 setae in each fringe.

Dimensions: TW, 0.45; HL, 0.31; PW, 0.28; PSL, 0.10; MW, 0.43; MSL, 0.15; AWIV, 0.55; ANW, 0.20; TL, 1.43.

Male. Metanotum with 10 marginal setae. Tergal setae: I, 11; II, 17; III –VI, 13–16; VII, 12; VIII, 10. Sternal setae: II, each aster with 4 setae, 19 other setae; III, 19; IV, 21; V, 26; VI, 21; VII, 12; VIII, 5. Genital sac sclerite as in Fig. 16View FIGURES 9 – 17. 9 – 10. Dimensions: TW, 0.40; HL, 0.28; PW, 0.26; PSL, obscured; MW, 0.35; MSL, 0.13; AWIV, 0.44; GL, 0.38; TL, 1.12.

Type material. Holotype female ( NMNH), ex M. olivaceus  , TRINIDAD: Simla nr Arima, 14 Mar 1980, R. C. Dalgleish 704. Paratype ( NMNH): 1 male, same data as holotype.

Remarks. The female, with the modified anterior tergites, is closest to Myrsidea cayanensis  , from which it is separable by its shorter postspiracular setae on VI –VII, a different spiculation configuration on the subgenital plate margin, 12 marginal metanotal setae, smaller dimensions, and more tergal setae on IV –VII. The male is identifiable by differences in its dimensions, quantitative chaetotaxy, and form of the genital sac sclerite.
