Crematogaster flaviventris Santschi Figure 15 A–C

Taxonomic history.

Crematogaster flaviventris Santschi, 1910: 370 (w, q, m) Democratic Republic of Congo.

Subspecies of C. inversa: Santschi 1914a: 86; of C. castanea: Santschi 1935: 257.

Status as species: Collingwood and Agosti 1996: 330.

Geographic range.

Crematogaster flaviventris was originally described from the Democratic Republic of Congo and is also found in Angola, Zambia, and southern Sudan ( Guénard et al. 2017; Janicki et al. 2017). On the Arabian Peninsula, it seems to be restricted to Yemen (Collingwood and Agosti 1996; Blaimer 2012a; Borowiec 2014) (Fig. 16).

Remarks.

This species record for Yemen is somewhat dubious. We have not examined the type material but preliminary examination of type images on AntWeb suggest that the material from Yemen is similar in color but there appear to be substantial differences in overall surface sculpture. This needs to be further investigated, ideally by comparing the Yemeni material with the type from Central Africa.
