    The distribution area of Podarcis erhardii includes the southern Balkans and numerous Aegean Islands. Podarcis erhardii is a typical Wall Lizard without any special habitat preferences. About 20 subspecies have been described – in particular for the Aegean Islands – although most of them are likely to be invalid. Anyhow, within this species a big genetic and morphologic variety can be found. At least the mainland populations and those from the Aegean Islands could be two different species. If a deeper systematic structure would be required, the following schedule could be helpful:

    Mainland:
    - Podarcis erhardii riveti: Bulgaria, Macedonia, Serbia, Kosovo, Northern Greece, possibly also Northern Sporades.
    - Podarcis erhardii livadiacus: Attika, Evia and north-eastern Peloponnese

    The status of subsp. ruthveni from the Northern Sporades is unclear so far: Some genetic analysis indicate that it clusters with subsp. riveti. Other analysis indicate that this is a seperate group.


    Aegean Islands:
    - Western lineage – western Cyclades (Sifnos and Serifos – the lizards from these island correspond to the nominate subspecies - and Kithnos)
    - Central lineage – numerous islands of the central Cyclades including Tinos, Mykonos, Naxos
    - Eastern lineage – East-Aegean Islands (Anafi, Astypalea and some uninhabited islets)

    The western and central lineage may constitute one group.

    Currently, one could only speculate about the future taxonomy – here, still a lot of research has to be done.

  • Distribution range of Podarcis erhardii

    Subsp. riveti:

  • Subsp. riveti, male: GR / Ossa, 03.06.2009

    The distribution area of Podarcis erhardii riveti overlaps with Podarcis muralis, Podarcis tauricus and Podarcis ionicus. Both species can look quite similar – but Podarcis muralis frequently shows a dark vertebral line which lacks in Podarcis erhardii riveti. Where both species co-occur, Podarcis muralis occupies more humid micro-habitats.

    Males of Podarcis erhardii riveti frequently have reddish undersides whereas Podarcis tauricus usually has yellowish or whitish undersides. Furthermore, Podarcis tauricus shows bright green colors in spring which lack in Podarcis erhardii riveti. The same applies to differences between Podarcis erhardii riveti and Podarcis ionicus.

  • Subsp. riveti, male: GR / Vikos, 10.06.2009

    Subsp. livadiacus:

  • Subsp. livadiacus, male: GR / Peloponnes, 26.10.2012

    This subspecies seems to have a preference for mountainous habitats (on Evia and Peloponnese it lives in altitudes above 1000 m – but there also have been records for lower elevations).

    It can be distinguished from Podarcis muralis by the lacking of a vertebral line. Furthermore, males of Podarcis erhardii livadiacus show a characteristic bronze-colouration on their backs and shoulders. Where both species co-occur (e.g. Evia, Peloponnese), Podarcis muralis inhabits more humid micro-habitats.

    On Peloponnese, Podarcis erhardii livadiacus and Podarcis peloponnesiacus occur in syntopy. In particular, females of these species can look very similar. But, Podarcis erhardii usually has dark spots on the labial scales which lack in Podarcis peloponnesiacus. Furthermore, Podarcis peloponnesiacus has a dark vertebral line, which lacks in Podarcis erhardii.

    Podarcis erhardii livadiacus can hardly be confused with Podarcis ionicus, which also occurs on Peloponnese. In particular, Podarcis ionicus shows bright green colors in spring, which lack in Podarcis erhardii livadiacus.

    Cyclades - Western Lineage:

  • Subsp. erhardii, female: GR / Serifos, 18.04.2018

    On Serifos, males as well as females have strinking yellow throats. Within its distribution area, Podarcis erhardii erhardii is the only small Lacertid and cannot be confused with other species.

  • Subsp. erhardii, male: GR / Sifnos, 07.06.2011 - In contrast to Serifos, lizards of Sifnos have whitish throats.

    Cyclades - Central Lineage:

  • Subsp. naxensis, male: GR / Naxos, 29.03.2016

    Specimens from the western and central Cyclades look very similar (see also first picture) but there seem to be genetic differences. These lizards are quite variable in pattern and colouration. As they are the only small Lacertids within their distribution area, they cannot be confused with other species.

  • Subsp. naxensis, male: GR / Naxos, 01.04.2016

  • Subsp. naxensis, male: GR / Naxos, 30.03.2016

    Cyclades - Eastern Lineage:

  • Subsp. syrinae, male: GR / Astypalaia, 26.03.2016

    The lizards of the eastern Aegean Islands differ from those on the central Cyclades: Compared to the lizards of the Central Cyclades they have short limbs and longer heads with pointed snouts. This eastern form is so far poorly known – therefore, also their future taxonomic status is unclear.

  • Subsp. syrinae, pair: GR / Astypalaia, 26.03.2016

  • Male: GR / Pergousa, 18.05.2018 - The populations of Pergousa and Pachia so far haven't been referred to any subspecies. However, they belong as well to the eastern lineage. These are the only populations of Podarcis erhardii east of the Mid-Aegean Trench.
