title: [Morphology and chaetotaxy of Sanguinicola armata cercaria (Trematoda: Sanguinicolidae)].
abstract: A morphological description of Sanguinicola armata cercaria is given. This larva belongs to the group of brevifurcate and apharingeal cercariae. Mouth opening is on ventral surface of the anterior organ. The body and branches of the furca bear a membrane. The body/tail ratio is much more than in other cercariae of the family Sanguinicolidae. The gland apparatus of the larva is represented by several types of secretory cells. The penetration glands form a group of 5 pairs of cells on the ventral side. Their ducts form a single bunch directed anterior, go through the anterior organ and open terminally on the proboscis, which is able to turn outside. Other gland cells apparently represent specialized cytones of the tegument. Excretory formula: 2[(1 + 1) + (1 + 1)] = 8. The external surface of the larva bears a small number of sensilla. Some similarities of the families Sanguinicolidae and Schistosomatidae in the cheatotaxy of cercaria have been noticed.
