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.
