Abstract

A new species of digenean inhabiting the white-tipped dove, Leptotila verreauxi Bonaparte, 1855, in the Area de Conservación 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 spotted antbird, Hylophylax naevioides Lafresnaye (1847); and the white-lored gnatcatcher, Polioptila albiloris, are new hosts for Bakkeius moragai Zamparo, Brooks, and Causey, 2003. A revised key to the leucochloridiid-like brachylaimoid genera is presented that accommodates this new genus.
