Neomichajlovia guanacastensis n. g., n. sp. (Digenea: Brachylaimoidea) in the White-Tipped Dove, Leptotila verreauxi (Aves: Columbidae), and New Host Records for Other Leucochloridiid-Like Brachylaimoids from the Area de Conservación Guanacaste, Costa Rica

Abstract

Abstract A new species of digenean inhabiting the white-tipped dove, Leptotila verreauxi Bonaparte, 1855, in the Area de Conservacion Guanacaste, Costa Rica, resembles Pojmanskia riosae Zamparo, Brooks, and Causey, 2003, but it differs in having a spined cirrus, pars prostatica outside the cirrus sac, ovary separated from the anterior testis by uterine coils to a length of at least two-thirds a testis diameter, and uterine loops in the hindbody not overlapping the ovary or posterior testis. The new species is also similar to species of Michajlovia Pojmanska, 1973, but it differs by having a spined cirrus, and gonads well separated from each other. Consequently, we propose a new genus for the new species. The great crested flycatcher, Myiarchus crinitus Linnaeus, 1758; white-lored gnatcatcher, Polioptila albiloris Sclater & Salvin, 1860; streak-headed woodcreeper, Lepidocolaptes souleyetii Des Murs, 1849; and the elegant trogon Trogon elegans Gould (1834) are new hosts for Pojmanskia riosae; and the spotte...
