Myrsidea dorotheae Eichler ( Fig. 16 )

Myrsidea dorotheae Eichler 1953: 301 . Type host: Pteroglossus azara mariae Gould.

Female. Much as in Fig. 17 . Metanotal margin with 8–10 setae. Tergites III–V with slight medioposterior convexity intruding into the following tergite. Tergal setae: I, 13– 15; II, 15–20; III, 19–21; IV–VI, 18–22; VII, 16–17; VIII, 8–10. Postspiracular setae on III and V much shorter than others. Medium inner posterior marginal setae on IX. Sternal setae: II, 29–33; III, 34–38; IV, 40–45; V, 43–49; VI, 35–39; VII, 15–17; subgenital plate, 38–47. Anus with 38–45 ventral fringe setae, 43–47 dorsal. Dimensions: TW, 0.62–0.64; HL, 0.38–0.39; PW, 0.37–0.42; MW, 0.61–0.64; AWIV, 0.90–0.96; ANW, 0.35–0.37; TL, 2.07–2.21.

Male. Metanotal margin with 6–8 setae. Tergal setae: I, 10–14; II, 16–19; III–VI, 18– 25; VII, 15–18; VIII, 8–11. Medium inner posterior marginal setae on IX, much as in Fig. 1 . Postspiracular setae on III and V shorter than others. Sternal setae: II, 27–36; III, 29– 34; IV, 36–42; V, 36–43; VI, 35–39; VII, 19–24; VIII, 10–15. Genital sac sclerites as in Fig. 16 , with bifurcation on each side. Dimensions: TW, 0.56–0.58; HL, 0.35–0.37; PW, 0.35–0.38; MW, 0.50–0.52; AWIV, 0.63–0.67; GL, 0.54–0.58; TL, 1.73–1.86.

Material. Ex P. a. m a r i a e, 4 males, PERU: Dept. Madre de Dios, Hda. Amazonia, near Atalaya Ridge 330 m. above Hda. (DHC­85­058; 1985); 2 females, PERU: Loreto, 86 km SE Juanjui on E bank upper Rio Pauya, 07°38'40" S, 75°54'58" W (MSS­3666; 2000). Ex P. inscriptus humboldti Wagler , 2 female, 2 males, PERU: Loreto, 36 km SE Juanjui on E bank upper Rio Pauya, 07°35'10" S, 75°56'01" W (JLK­219; 2001); 1 male, PERU: Dpto. Loreto (JWA­80; 2000); 1 male, BRAZIL: Amazonas, N bank Rio Solimões, ca 4.5 km NE São Paulo de Olivença, 03°25' S, 68°57' W (AA­680; 2000).

Remarks. Eichler (1953) gave a brief essentially useless description of this species based on a single female and accompanied by a meaningless illustration of the prosternal plate. Both sexes of M. dorotheae differ from M. abbreviata by their shorter postspiracular setae on III and fewer sternal setae on IV–VI. Males also are distinguished by their unique genital sac sclerites ( Fig. 16 ).
