Revolving SEM images visualising 3D taxonomic characters: application to six species of the millipede genus Ommatoiulus Latzel, 1884, with description of seven new species and an interactive key to the Tunisian members of the genus (Diplopoda, Julida, Julidae)

Abstract. A novel illustration technique based on scanning electron microscopy is used for the first time to enhance taxonomic descriptions. The male genitalia (gonopods) of six species of millipedes are used for construction of interactive imaging models. Each model is a compilation of a number of...

description Abstract. A novel illustration technique based on scanning electron microscopy is used for the first time to enhance taxonomic descriptions. The male genitalia (gonopods) of six species of millipedes are used for construction of interactive imaging models. Each model is a compilation of a number of SEM images taken consecutively while rotating the SEM stage 360°, which allows the structure in question to be seen from all angles of view in one plane. Seven new species of the genus Ommatoiulus collected in Tunisia are described: Ommatoiulus chambiensis, Ommatoiulus crassinigripes, Ommatoiulus kefi, Ommatoiulus khroumiriensis, Ommatoiulus xerophilus, Ommatoiulus xenos, and Ommatoiulus zaghouani spp. n. Size differences between syntopic adult males of Ommatoiulus chambiensis and Ommatoiulus xerophilus spp. n. from Châambi Mountain are illustrated using scatter diagrams. A similar diagram is used to illustrate size differences in Ommatoiulus crassinigripes, Ommatoiulus khroumiriensis spp. n. and Ommatoiulus punicus (Brölemann, 1894). In addition to morphological differences, the latter three species display allopatric distribution and different habitat preferences. A dichotomous interactive key with a high visual impact and an intuitive user interface is presented to serve identification of the 12 Ommatoiulus species so far known from Tunisia. Updates on the North African Ommatoiulus fauna in general are presented.
