56 R. Bosmans & P. Oger A new case of male dimorphism: Savignia harmsi Wunderlich, 1980 (Figs 3a-d, 4a-d, 5a-g) Savignia harmsi Wunderlich, 1980: 332, figs 45-51 (de- scr. ) , ( ). Material examined. SPAIN: Granada: Baza, 5 )) 1 ( , pitfalls in dry riverbed, 12.xi.1990, L. Zarcos coll. (CRB). Comments. At first glance, the five studied males appear to belong to different species, because their prosomas have very different shapes (Figs 4a-c, 5a-c). However, their palp confor- mation is identical (cf. Figs 3e and 3d).The first morph (Fig. 4a-b) has a nose-like projection carrying the anterior median eyes, like in Savignia frontata Blackwall, 1833. Apparently, because of this resemblance Wunderlich (1980) placed the species in the genus Savignia . The second morph (Fig. 4c-d) has a completely different cephalic lobe in the form of a large, rounded lobe, heart-shaped in the anterior view (Fig. 4d). For this morph, the name cor (Latin for heart) is herein proposed. If this morph was found first, the species would probably have been described in Diplocephalus . Distribution. S. harmsi was described from both sexes from Spain, in the province of Malaga (Wunderlich 1980). It was recollected from the neighbouring province of Granada. It was not yet recorded since the original description (Morano et al. 2014). Acknowledgements Christine Rollard (MNHN) and the individual collectors mentioned in ‘Material and methods’ are sincerely thanked for allowing us to study the material of Diplocephalus species under their care. Thanks also to Laura Zarcos for providing the specimens of Savignia harmsi . Finally, we wish to thank Antony Russell-Smith and an anonymous referee for their critical comments on the manuscript which helped us to improve it.
