Xuming Pan, 2016, Seven scuticociliates (Protozoa, Ciliophora) from Alabama, USA, with descriptions of two parasitic species isolated from a freshwater mussel Potamilus purpuratus, European Journal of Taxonomy 249, pp. 1-19 : 10

Uronemita filificum Kahl, 1931

Fig. 4A–E ; Table 1

Subsequent to Kahl’s (1931) original description, Pérez-Uz et al. (1996), Song & Wilbert (2002), and Song et al. (2002a) have provided supplemental information on the species. The Alabama population is identical to that of Kahl (1931) and Pérez-Uz et al. (1996) but differs from that of Song & Wilbert (2002) and Song et al. (2002a) in the number of somatic kineties (18 or 19 vs 20–23).

A, F, J. Ventral views of typical individuals. B – C, G – H, K – L. Different individuals, showing variation in body shape, arrow in (B) shows the conspicuous apical plate, arrows in (C, H) mark contractile vacuoles. D, I, M – N. Detailed structures of buccal area, arrow in (M) indicates the ring-like posterior end of M 2 a, arrowheads in (M) mark preoral kineties. E. Ventral view, arrowheads show somatic kineties. Abbreviations: M 1, 2, 3 = membranelle 1, 2 and 3; M 2 a = the anterior part of membranelle 2; M 2 b = the posterior part of membranelle 2; Ma = macronucleus; PM = paroral membrane.
