Nematoda: Trichostrongyloidea parasites of Venezuelan wild mammals. III. The genus Vexillata Travassos, 1937.
Two new species of the genus Vexillata Travassos, 1937 parasitizing Heteromys anomalus of Venezuela are described, V. tejerai n. sp. and V. scorzai n. sp., both close to V. petteri Durette-Desset, 1970 and V. chabaudi Yoyotte-Vado, 1972, by possessing of 4 dorsal ridges and the dorsal rib divided near the tip. Both new species are differentiated from V. chabaudi by having the dorsal rib much shorter than rib 8; they are distinguished from V. petteri by having ribs 2 and 3 nearly the same size. The two new species are separated by the significantly greater size of V. tejerai and by the form of the copulatory bursa. A brief historical review of the genus is given, together with considerations on its origin and its probable relation to the Pudicinae or Brevistriatinae. A key to the 8 known species is also given.
