Genus Ionemobius Otte, Alexander & Cade, 1987 Ionemobius Otte, Alexander & Cade, 1987: 411. Ionomobius – Otte, Alexander & Cade 1987: 411 (mispelling). TYPE SPECIES. — Ionemobius alliciens Otte, 1987, by subsequent designation (see infra). ILLUSTRATIONS. — Habitus pp: Otte et al. 1987: figs 13C, 14F. Male genitalia: Otte et al. 1987: fig. 17A. DIAGNOSIS. — After Otte et al. 1987. Similar to Thetella, except for the number of TII apical spurs (3, instead of 2 in Thetella). Otte et al. (1987) consider that Thetella and Ionemobius are so similar that they could belong to the same genus; no specimen could however be studied to check this hypothesis. DISTRIBUTION. — Endemic to New Caledonia. Known from the type locality of the type species only (coastal forest near Thio). HABITAT. — Otte et al. (1987: 412) mention that I. alliciens has been “collected along a small stream and along the stony shoreline among wet stones and debris”. This habitat fits that of Thetella, which would support an hypothesis of synonymy between the two genera. REMARK In Otte et al. (1987), the type species indicated for Ionemobius is Amonemobius vexans Otte, 1987, which is clearly an error. In his Catalogue, Otte (1994a) mentions I. alliciens Otte, 1987 as the type species of Ionemobius, but not formally designates it as such.
