Site: external surface, too few infected ®sh seen to give more details. A`very small’ species according to scheme of Harris (1985). Body length of moderately ¯attened, moderately contracted specimens, less than 400 m m. Anterior of the pharynx (see Kritsky, 1971) consisted of eight cells arranged in a ring which were fused to each other along their lateral borders. Thirty-seven ¯attened specimens mounted in ammonium picrate-glycerin for sclerite examination had a pharynx mean length of 41 m m (SD 5 m m) and width of 37 m m (SD 4 m m). The anterior and posterior pharyngea l bulbs were of approximatel y equal width, although the width of the posterior part was greater for most specimens. Measurements of attachment hooks and bars are given in table 1; ventral bars and marginal hooks were most distinctive (®gures 1 and 9). The ventral bar had long, slightly curved antero-lateral processes, converging towards each other apically (®gure 1). The dorsal bar had a median notch (®gure 1), though this was not always obvious. Marginal hook blade point was extended nearly level with or beyond the toe. The marginal hook blade had a pronounced bend immediately before the point (®gure 1), just visible using phase contrast, was most readily seen by SEM (®gure 2). The cirrus had one large spine with a bifurcate base at both sides (®gure 3A) and a single row of four to seven small spines (®gures 3A and 4).</p> </div>	http://treatment.plazi.org/id/03AB5A723070FF928561FAA24825F939	Public Domain	No known copyright restrictions apply.

Site: external surface, anterior of ®sh, particularly head and opercula regions. A`very small’ species according to scheme of Harris (1985). Body length of moderately contracted living specimens under 400 m m. Anterior of the pharynx (see Kritsky, 1971) consisted of eight cells arranged in a ring which were fused to each other along their lateral borders. The anterior and posterior pharyngeal bulbs of ¯attened specimens were of approximately equal width. Pharynx measurements were not taken. Measurements of attachment hooks and bars are given in table 1. The most distinctive elements were the connecting bars and the marginal hooks (see ®gures 6 and 7). The ventral bar had relatively long antero-lateral processes and a membrane which tapered slightly posteriorly. The dorsal bar had an obvious notch at the mid point with two swellings on either side (®gure 6). The marginal hook blade was bent at an angle of about 90ss with a straight point not extending as far as the toe. The cirrus had one large spine with the base on each side curved behind and joined (®gure 3B) and a single row of four to seven small spines (®gure 8).</p> <p>Gyrodactylus bullatarudis from P. reticulata infected and reproduced on seven Xiphophorus hybrids. An increasing G. bullatarudis infrapopulation caused the death of one Xiphophorus, but six infrapopulations went extinct between one and ten days af ter infection (®gure 10).</p> </div>	http://treatment.plazi.org/id/03AB5A72307DFF9F8552FAEC4B28F939	Public Domain	No known copyright restrictions apply.
