New Records and Updated Checklist of the Pentatomoidea (Hemiptera: Heteroptera) of Greece.

Eight species of the superfamily Pentatomoidea are recorded from Greece for the first time: Küster 1852, (Fabricius 1775), (Scopoli 1763), (Herrich-Schaeffer 1830), (Gallen 1789), (Linnaeus 1758), (Fabricius 1775) and (Jakovlev 1871). A complete updated species checklist with distributional data notes for all the new species for Greece are provided.

New distributional and bioacoustic data about Cicadivetta goumenissa from Peloponnese, Greece (Hemiptera, Cicadidae).

Cicadivetta goumenissa, a small singing cicada described recently by Gogala et al. (2012), has been previously found only around the village of Goumenissa in northern Peloponnese. We visited this area again in June 2012 and tried to determine the distribution range of this species.

Mediterranean species of the spittlebug genus Philaenus: modes of chromosome evolution.

The evolution of karyotypes and sex determination system of Philaenus Stål (Auchenorrhyncha: Aphrophoridae) species is studied here in detail. The most plausible scenario of chromosomal rearrangements accompanying phylogenetic differentiation in Philaenus is advanced. It is postulated that the ancestral karyotype of Philaenus was 2n = 24 + X0.
