Description of Discophrya ordesae Fernández-Leborans & Valladolid, sp. n. Derivatio nominis: from Ordesa valley (Pyrenees, Comunity of Aragón, Spain). Ciliate suctorians located mainly in ventral areas of abdomen and thorax (in this case between legs), in number of 1–2, rarely 3 individuals per basibiont (Figure 5). Fanlike body (222–238 µm long, and 255–277 µm wide) with distal end uniformly rounded and proximal end strait and connected to the stalk (Figures 6–7). Body very flattened. Distal edge of the lorica double with capitate tentacles inserted (135–148), of variable length (Figures 8–9) as they are retracted or not (5.3–15.5 µm retracted; 27.2–102.2 extended). Stalk short (86.3–97.2 µm) and thick. Distal end of stalk joining to the basibiont by a slightly expanded region. Proximal part of the stalk continued by a lorica (stylotheca) with thick edge and strong surrounding the cellular body. Macronucleus located in the middle of body (Figure 10–11), oval or rounded (100.4–125 µm long, 109.3– 127 µm wide). In several specimens, larval kineties may be observed in the centre of the body (Figure 12), with the cilia protruding laterally, probably constituting the development of the swarmer on brood pouch (Table 4). Evaginative budding. Registration numbers: MNCN 39.04/5-39.04/7. Distribution. It was found attached to ventral area, mainly in abdomen, of Hydraena delia and H. truncata (Coleoptera: Hydraenidae). From Yaga river (Table 2).

Description of Tokophrya cf. stenostyla Hamilton & Jahn The suctorians analyzed (Figures 2–3) had an oval elongated body (51–53 µm long, 20–42 µm wide). In several individuals there was a cap-shaped region protruding from the front end of the body. The posterior end of the body was truncated just above the junction of the stalk. Tentacles spread at the distal end, not grouped in actinophores. There were 20–25 tentacles, directly attached to the surface of the ciliate. The stalk was long (105–121 µm), and its posterior end was widen slightly in attachment with substrate. The anterior end showed a widening near the body, composed by an unequal double ring. The macronucleus was spherical or oval (19–29 µm long, 17–27 µm wide), located in the middle or slightly towards the anterior half of the body (Table 3). Registration numbers: MNCN 39.04/2-39.04/4 Distribution. They were found attached principally to the dorsal area (Figure 4) of elytra of several species of Hydraena: H. delia, H. subimpressa and H. truncata (Coleoptera: Hydraenidae). Found in rivers Bellós and Yaga.
