| Summary: | Strigea macropharynx sp. n. (Trematoda : Strigeata, Strigeidae), an intestinal parasite of Falco rusticolus L., is described. Falconiformes harbor two species of Strigea (S. falconis Szidat, 1928, and S. macroconophora,/i> Dubois and Rausch, 1950) with vitellaria terminating near the copulatory bursa. Both differ from the new species in having a pharynx that is smaller than or subequal to the buccal sucker, as well as in other details. In S. elegans Chandler and Rausch, 1947, a parasite of Strigiformes, the eggs are larger, the testes of different form, and the vitellaria extend significantly farther into the region of the copulatory bursa. The very intimate contact existing between the tribocytic organ of S. macropharynx and the intestinal mucosa of the host suggests that extracorporeal digestion of host tissue takes place. |
