Figure 3. Cranial morphology of Tanganikallabes species (and Clarias gariepinus for comparison), showing interspecific differences in orbital and lateral ethmoid morphology, as well as overall reductions of cranial osteology. A, Tanganikallabes mortiauxi (UMMZ 199862), in which infraorbital iv (io-iv) is composed of a single element and the extensions of the lateral ethmoid nearly overlie io-ii. B, C, Tanganikallabes alboperca sp. nov. (UMMZ 199861) and Tanganikallabes stewarti sp. nov. (UMMZ 196154), respectively, in which io-iv consists of two elements and the extensions of the lateral ethmoid do not reach io-ii. D, Clarias gariepinus, UMMZ 166654. E, Drawing of T. alboperca sp. nov. skull (UMMZ 199861), more clearly showing delimitations of cranial elements in Tanganikallabes.Published as part of Wright, Jeremy J. & Bailey, Reeve M., 2012, Systematic revision of the formerly monotypic genus Tanganikallabes (Siluriformes: Clariidae), pp. 121-142 in Zoological Journal of the Linnean Society 165 (1) on page 127, DOI: 10.1111/j.1096-3642.2011.00789.x, http://zenodo.org/record/540719
