Johnson; 1 female, same except GMS 1770; (USNM) 1 female, 1 male, PANAMA: Lago Bayano, 12 Feb. 2006, GMS 1768. Remarks. This species is separated from the following two species of the group by the combination of dimensions and number of metanotal marginal setae of both sexes, length of male genitalia, and number of setae on male abdominal tergites and dorsal anal fringe of the female. Etymology. This species is named for John Klicka, Marjorie Barrick Museum, University of Nevada, Las Vegas, in recognition of his assistance in collecting the lice used in this study and for his work on avian systematics.Published as part of Price, Roger D., Johnson, Kevin P. & Dalgleish, Robert C., 2008, Five new species of Myrsidea Waterston (Phthiraptera: Menoponidae) from antshrikes and antbirds (Passeriformes: Thamnophilidae), pp. 55-62 in Zootaxa 1819 on pages 56-58, DOI: 10.5281/zenodo.18296
Myrsidea vincesmithi Price, Johnson
No full textMyrsidea vincesmithi Price, Johnson, and Dalgleish, new species Type host. Thryothorus rutilus Vieillot, 1819, the Rufous-breasted Wren. Female. Unknown. Male. As for M. bessae, except as follows. Metanotum with 11 marginal setae; metasternal plate with 6 setae. Tergal setae: I, 13; II, 16; III–IV, 18; V, 16; VI, 15; VII, 14; VIII, 12. Postspiracular setae shortest on III and V–VI (not> 0.21 long), extremely long on VII, as long as on VIII. Sternal setae: II, each aster of 3 or 4 setae, 17 marginal between asters, 10 anterior; III, 20; IV, 26; V, 31; VI, 27; VII, 19; VIII, 8. Dimensions: TW, 0.43; HL, 0.29; PW, 0.28; MW, 0.39; AWIV, 0.47; GL, 0.40; TL, 1.22. Type material. Holotype male (to TNHM), ex T. rutilus, TRINIDAD: Cumuto, 17 May 1960, TRVL 4398, Brit. Mus. 1974 - 636. Remarks. While we generally are reluctant to describe a new species from only a single specimen, the differences are so marked in this case that we feel justified in doing so. This species is closest to M. bessae, but is separable by having more setae on all abdominal tergites and sternites as well as on the metanotal margin, and by having an extremely long postspiracular seta on tergite VII. Etymology. This species is named in honor of Vincent Smith, The Natural History Museum, London, in recognition of his contributions to taxonomic databases for lice and work on louse systematics.Published as part of Price, Roger D., Johnson, Kevin P. & Dalgleish, Robert C., 2008, Myrsidea Waterston (Phthiraptera: Menoponidae) from wrens (Passeriformes: Troglodytidae), with descriptions of three new species, pp. 59-65 in Zootaxa 1740 on page 63, DOI: 10.5281/zenodo.18149

Holotype male (INHS), ex H. naevioides, PANAMA: Rio Mono, 20 Feb. 2006, JKO 6- 112, K. Johnson. Paratypes: (INHS) 2 females, same data as holotype; (USNM) 1 female, 1 male, same data as holotype. Remarks. This species is the smallest of the three species in this group, with both sexes having shorter postspiracular setae on VII and dimensions smaller than those of M. dacostai. This separation is further supported by the male having more tergal setae on III–IV than M. klickai and the female having fewer anal fringe setae and a larger number of anterior setae on sternite II. Etymology. This species is named for Garth Spellman, Black Hills State University, Spearfish, South Dakota, in recognition of his assistance in collecting the lice used in this study and for his work on bird systematics.Published as part of Price, Roger D., Johnson, Kevin P. & Dalgleish, Robert C., 2008, Five new species of Myrsidea Waterston (Phthiraptera: Menoponidae) from antshrikes and antbirds (Passeriformes: Thamnophilidae), pp. 55-62 in Zootaxa 1819 on pages 58-59, DOI: 10.5281/zenodo.18296

Paratypes: 4 females, 1 male (to USNM), 1 female, 1 male (to INHS), same data as holotype. Remarks. Both sexes of this species may readily be recognized by a combination of their large dimensions, their large number of abdominal tergal and sternal setae, their longer and more numerous aster setae on sternite II, and the hypopharynx with weakly developed sclerites.
