Acanthinozodium tibesti Jocque 1991

Acanthinozodium tibesti Jocqué, 1991 Figs 17–18, 105 Acanthinozodium tibesti Jocqué, 1991: 130, figs 315–319. Acanthinozodium crateriferum Jocqué & Henrard, 2015: 4, figs 1a–e, 2a–c, 3a–c. Syn. nov. Acanthinozodium tibesti – Jocqué & Henrard 2015: 21, fig. 12a. Diagnosis For male diagnosis, refer to Jocqué & Henrard (2015). Females can be distinguished from other congeners by a pair of triangular atria separated by a thin median septum (Fig. 18A–B). Material examined EGYPT • 1 ♀; Cairo, Mariout, Aswan; MNHN-AR2847. Description For a detailed description of female, refer to Jocqué (1991). Remarks During our examination of the Simon collection, we identified a tube labelled Zodarium longipes rubidus MNHN-AR2847, which contained one female specimen of A. tibesti beside additional specimens belonging to Z. nitidum. Acanthinozodium tibesti was originally described from a single female collected in Chad (Jocqué 1991: figs 315–319). Then, Jocqué & Henrard (2015: fig. 12a) provided a photograph of the epigyne to elucidate morphological features. In the same study, they described A. crateriferum from Ethiopia – a species morphologically very similar to A. tibesti – and provided a comparative diagnosis that emphasized distinctions between A. crateriferum and A. zavattarii Caporiacco, 1941. Upon detailed morphological comparison of the specimen from the Simon collection with the descriptions and illustrations of both A. tibesti and A. crateriferum, we found no substantial diagnostic differences to justify their separation. Accordingly, we propose that A. crateriferum should be synonymized with A. tibesti, with the former being recognized as a junior synonym. Distribution Acanthinozodium tibesti was formerly recorded from Chad and Ethiopia; this is the first report of this species from Egypt.
