Type locality
LIBYA: Cyrenaica.
Remarks
Solari (1925)
provided the following (type) localities (included in
Fig. 12
): Derna, Zavia (= Az Zawiyah), Mechili, Tecnis (= Taknis) and Tolmetta. The first records of
P. festae
outside of Libya were already reported by
Germann
et al.
(2015)
as specimens of an unknown
Conocetus
sp. from Samos Island. It is remarkable that this brachypterous and thus supposedly little-mobile species occurs across the Mediterranean Sea. This can be explained by the recent introduction of this species in Greece (Samos Island and Crete), although the first specimens known from Crete (without collecting date, see above) were collected by Gustav Paganetti-Hummler (1871–1949), hence a very recent introduction can be excluded.
Polydrusus festae
is therefore recorded here for the first time from Greece.
Variability and similar species
The species was compared with both
P. baudii
and
P. marcidus
by
Solari (1925)
, based on the key by
Schilsky (1910)
. The squamulate scutellum, the head shape, pronotum and the oval elytra (
Fig. 1C–D
) as well as its brachyptery are very characteristic and not shared with other species of the subgenus.
Ecology
Collected from February (
Solari 1925
) to June, from the sea shore to colline altitudes. Found on flowering
Quercus ilex
bushes (G & U. Müller and C. Germann; photograph of the habitat in
Germann
et al.
2015
).
