Salmonema Moravec, Santos & Brasil-Sato, 2008
Generic diagnosis (after Moravec et al. 2008). Cystidicolidae . Medium sized nematodes. Pseudolabia broad, flat; surface of each pseudolabium with small protuberance (pseudolabial protrusion). Mouth opening broad, somewhat dorso-ventrally elongated, demarcated by four narrow, unlobed sclerotized plates (sublabia). Four submedian cephalic papillae present. Vestibule elongated, dilated anteriorly (dorso-ventrally) to form funnel-shaped prostom. Deirids simple, small. Male with an area rugosa. Caudal alae in male well developed, supported by pedunculate papillae; four pairs of pre-cloacal papillae present. Spicules unequal and dissimilar. Female tail short. Uterus amphidelphic. Vulva in posterior half of body. Eggs elliptical, nonfilamented [sic], containing fully formed larva. Parasites of fresh-water fishes. Type species S. ephemeridarum (von Linstow, 1872) .
Comments: design of a key to distinguish Salmonema ephemeridarum from S. prevosti (synonym Metabronema prevosti ) would be fraught. Apart from the fact that S. prevosti males were inadequately described, and that neither males nor females were well illustrated (see below), there is the structure of the eggs. The foregoing generic diagnosis of Salmonema states that eggs are “nonfilamented” whilst Choquette’s (1951) original description refers to eggs bearing “coarse filaments at either poles which are provided with knobs”.
