Price, Roger D., Hellenthal, Ronald A. & Weckstein, Jason D., 2004, The genus Myrsidea Waterston (Phthiraptera: Menoponidae) from the toucans (Piciformes: Ramphastidae), with descriptions of three new species, Zootaxa 613, pp. 1-18 : 13

Myrsidea lanei Price, Hellenthal and Weckstein , new species ( Figs. 17–18 )

Type host. Pteroglossus aracari (L.).

Female. As in Fig. 17 . Metanotal margin with 6 setae. Tergites III–V with slight medioposterior convexity. Tergal setae: I, 15; II, 20; III–VI, 23–26; VII, 15; VIII, 8. Postspiracular setae very long on I–VIII. Medium inner posterior marginal setae on IX. Sternal setae: II, 31; III, 37; IV–VI, 42–49; VII, 22; subgenital plate, 36. Anus with 44–45 setae in each fringe. Dimensions: TW, 0.69; HL, 0.41; PW, 0.45; MW, 0.69; AWIV, 1.05; ANW, 0.43; TL, 2.38.

Male. As for female, except as follows. Tergites III–V unmodified. Tergal setae: I, 12–13; III, 22; IV, 21–23; V–VI, 22–24; VII, 14–16. Sternal setae: V, 42–48; VI, 35–43; VII, 21–28; VIII, 10–14. Genital sac sclerites as in Fig. 18 . Dimensions: TW, 0.61–0.64; HL, 0.38; PW, 0.43; MW, 0.58–0.60; AWIV, 0.74–0.79; GL, 0.62–0.63; TL, 1.97.

Type material. Female holotype, ex P. aracari , BRAZIL: Pará, 30 km NE Belém, Fazenda Morelândia, 01°12'40" S, 48°14'47" W, 14 Aug. 1999, JDW (MO­004); 2 male paratypes, same data as holotype.

Remarks. The very long postspiracular setae on III and V, the consistently larger dimensions, the male genital sac sclerites without a lateral bifurcation ( Fig. 18 vs. Fig. 16 ), and the female metanotal margin with only 6 setae allow separation of M. lanei from M. dorotheae and M. aleixoi .

Etymology. This species is named for Daniel F. Lane, Louisiana State University, in recognition of his help in collecting many valuable louse specimens used in this and other studies of lice.
