However, a reanalysis of this material following the publication of Ríos & Duffy (2007) revealed that neither of the two specimens of <i>S.</i> cf. <i>pandionis</i> represents <i>S. pandionis s. str</i>. One of them has all the diagnostic characters of <i>S. ul</i>, originally described from Belize and Panama (Ríos & Duffy 2007). The scaphocerite of the Bahian specimen of <i>S. ul</i> has a distinct blade (Fig. 7 G) similar to that of <i>S. pandionis</i>. However, it differs from <i>S. pandionis</i> in having unequal spiniform setae on the posterior margin of the telson, with the lateral pair being shorter than the mesial pair (Fig. 6 D); these setae are subequal in length in <i>S. pandionis</i>. In <i>S. ul</i>, the distolateral tooth of the uropodal exopod is adjacent to the preceding spiniform seta (Figs. 6 E, F) (vs. more separated and with a small lobe between them in <i>S. pandionis</i>); and the mesial protuberance (erroneously referred as lateral side in Ríos & Duffy 2007) on the base of the major chela pollex, characteristic of <i>S. pandionis</i>, is absent (Fig. 7 F). <i>Synalpheus ul</i> also resembles <i>S. hoetjesi</i> Hultgren, Macdonald & Duffy, 2010, but differs from it by the presence of a scaphocerite blade (20–75% the length of scaphocerite vs. absent or vestigial in <i>S. hoetjesi</i>) (Fig. 7 G), the shape of the distal superior margin on the major chela (gently sloping in <i>S. ul</i> vs. bulging over the accessory tooth in <i>S. hoetjesi</i>) (Figs. 7 A, B), and the thickness of the spiniform setae on the posterior margin of the telson (mesial subequal to lateral in <i>S. ul</i> vs. mesial larger than lateral in <i>S. hoetjesi</i>).
