Emended diagnosis

Uroctea grossa is closest to U. thaleri Rheims, Santos & van Harten, 2007 and U. gambronica sp. nov., but differs from them and from other species of Uroctea by its larger size, its broad, V-shaped MAb2 making a sharp angle (also present in U. gambronica sp. nov.) and having a wide, fan-shaped terminal section (also present in U. thaleri, cf. Fig. 7 A–G), by its gently curved MAb1, its relatively long, stout, curved TL (Fig. 7C, also present in U. thaleri), its short and stout Bd and a Cd that is coiled over 360° and directed outwards anteriorly (vs uncoiled in U. limbata (C.L. Koch, 1843) and inwardly bent in U. thaleri; cf. Fig. 9B, Rheims et al. 2007: fig. 8 and Baum 1972: fig. 9).
