摘要

Five specimens of a new species of Uvitellina Witenberg collected from the air sacs of a black-winged stilt, Himantopus himantopus, collected from the Kherson Region of the Ukraine, were described. Of the 9 species in the genus, Uvitellina himantopin. sp. differs from all other species in the ratio of the width to the length of eggs (1:1.8 [1:1.6-1:1.9] compared to a low of 1:2.2 in Uvitellina adephis and a high of 1:3.6 in Uvitellina teesae). Uvitellina himantopi n. sp. is most similar to Uvitellina iraquensis because, unlike the other 4 species in the genus with a rudimentary oral sucker {Uvitellina indica, Uvitellina kaniharensis, Uvitellina macroisophaga, and U. teesae), these 2 species have an oral sucker that is typically wider than the pharynx (1:1.0-1:1.2 oral sucker width/pharynx width compared to 1:0.8-1:0.9 in the other 4 species) and a similar cirrus sac length (370-^K)0 long [3-4% of body length] compared to 300-490 [3-5%]). Uvitellina himantopi n. sp. has a larger body than U. iraquensis (12,118-15,100 long compared to 7,750-10,459), wider eggs (105 maximum width compared to 88), and unlike in U. iraquensis, the vitelline fields of U. himantopi n. sp. are attenuated posteriorly at their confluence to form a conspicuous, posteriorly directed point.
