Megaphyllum margaritatum: Enghoff & Kime 2009 .

Material examined. HNHM: Greece: 233, 2ƤƤ, 2009/79, Larisa county, Ossa Mts., beech forest, 975m, N39°48.087’ E22°45.666’, 0 9.04.2009, leg. LD, JK & DM.

Distribution in the Balkans. Greece: Attika: Keratea, Epirus: Elati (Strasser 1974, 1976).

World distribution. Widespread in Italy (Foddai et al 1995).

Remarks. Although far from Keratea, the gonopods of the newly collected males resemble var. keratea Strasser, 1974 . The flagella of the gonopod promeres of both males have a remarkable furcated apex (fl on Fig. 9).

Synonymy of M. aetnense, M. garganense and M. margaritatum has been discussed for a long time, especially by Strasser. Strasser & Minelli (1984) left the question open, writing that „…synonymy of margaritatum Fanz., aetnense Verh. and garganense Verh. is possible, but not sure…”. As we did not have enough individuals, we cannot add new information to this topic. However, if we accept the synonymy of these forms, the species seems to be very variable. In addition, the form creticum, one of the previous variants of M. margaritatum was elevated to species level several years ago (Ćurčiċ et al 2001). A thorough revision may produce similar results with other forms as well. Until then, M. margaritatum and M. cretica are the only two species in the subgenus Italoiulus .
