New or poorly known Mediterranean species of genus Psylliodes are considered. Topics are set as follows. 1) A new description of P. cereolus Peyerimhoff, P maculatipes Pic and P. moricandiae Peyerimhoff, three "yellow" species of instabilis group, is given: P. cereolus is compared with P fusiformis (Illiger) whereas P. maculatipes and P moricandiae are related to P. peyerimhoffi Heikertinger: a key (translated into English) to P. maculatipes and P peyerimhoffi is given. Lectotypus of P cereolus is designated. 2) P. caneparii, a new very characteristic yellow species of instabilis group is described from Calabria and Sicily; the new species vaguely reminds P testaceoconcolor Heikertinger and P. marcidus (Illiger) which differ by having spermathecal ductus devoid of coils; moreover Ps. testaceoconcolor has opaque pronotum and elytra (in P. caneparii they are fairly shining) whereas P. marcidus has a characteristic, very enlarged retrotarsal hollow of hind tibia. 3) P. biondii, a new species from Abruzzo and Molise is described: a key with English translation to separate the new species from the very closely related P. springeri Leonardi (from Monti Sibillini) and P. picipes Redtenbacher (from East and Maritime Alps) is given. The hypothesis to consider both P biondii and P. springeri as subspecies of P. picipes has been ruled out in accordance with modern trends of systematics and because the Apennine species are reproductively isolated from the Alpine one. On the ground of the examined characters P. biondii should be morphologically closer to P picipes than to P springeri. Neotypus of P. picipes (MWi) is designated. P. picipes is new to Serbia. 4) A new description of P. ellipticus Allard is given and Lectotypus of this species is designated. 5) Psylliodes metatarsalis, a new maghrebine species of ellipticus group is described, easily distinguishable by the shape of median lobe of aedeagus and of first metatarsal joint. This species is stenographically handwritten on page 798b added to page 798 of Heikertinger's copy of Weise's "Naturgeschichte der Insecten Deutschlands"; this book had been lost but friends of mine could luckily find it again put up for sale. Heikertinger had labelled as monotype a male specimen of his collection, collected by A. Schatzmayr in El Kantara, but there are three more specimens of the new species in my Museum, where Schatzmayr's collection is housed. 6) Distinguishing characters of ellipticus group are stressed and a key (translated into English) to species of ellipticus group (ellipticus Allard, metatarsalis n. sp., cerenae Gok, Doguet & Cilbiroglu, and belarbii Doberl) is given. 7) Geographic variability of P. wachsmanni is investigated; a key with English translation is given to separate the typic form from southern populations. The species is new to Jordan. 8) Geographic variability of P. wachsmanni is investigated; a key with English translation is given to separate the typic form from southern populations. The species is new to Jordan. 9) A new description of P. leonhardi Heikertinger, a very poorly known species of picinus group is given and new distributional data are added, which noticeably widen the areal of this taxon: P. leonhardi, which was known only from Sicily, has been collected also in Calabria, Lucania and North Apennine (Romagna, S. Marino); its aedeagal median lobe is described for the first time. 10) A new description of P. danieli Weise is given; P. rambouseki Heikertinger and its subspecies forojuliensis Heikertinger are considered junior synonyms of P. danieli. 11) P. parodii, a new species of glaber group from Alpi Apuane and Monti Sibillini is described; keys with translation into English to separate the new species from the closely related P. solarii and from P. laevifrons Kutschera are given. The paper is provided with 271 figures. As regards female female, besides spermatheca also spiculum and vaginal palpi are figured; apical bristles of vaginal palpi are not figured.
