Abstract

A novel illustration technique based on scanning electron microscopy is used for the frst time to enhance taxonomic descriptions. Te 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: O. chambiensis, O. crassinigripes, O. kef, O. khroumiriensis, O. xerophilus, O. xenos, and O. zag-houani spp. n. Size diferences between syntopic adult males of O. chambiensis and O. xerophilus spp. n. from Châambi Mountain are illustrated using scatter diagrams. A similar diagram is used to illustrate size diferences in O. crassinigripes, O. khroumiriensis spp. n. and O. punicus (Brölemann, 1894). In addition to morphological diferences, the latter three species display allopatric distribution and diferent habitat preferences. A dichotomous interactive key with a high visual impact and an intuitive user interface is presented to serve identifcation of the 12 Ommatoiulus species so far known from Tunisia. Updates on the North African Ommatoiulus fauna in general are presented.
