as
Eurytoma collina
Zerova
]
Aximopsis collina
was originally described in
Eurytoma
(
Zerova 1984
)
. It has been recorded as a parasitoid in galls of
Diplolepis
(Cynipidae)
on
Rosa
:
D. mayri
(Schlechtendal)
in Central Asia (
Zerova 2010
) and
Spain
(new record),
D. fructuum
(Rübsaamen)
in
Iran
(
Lotfalizadeh
et al.
2006
), and
D. rosae
(Linnaeus)
in
France
and
Iran
(
Askew
et al.
2006
). Specimens reared in this study from asphodel fruits have been compared with non-type material of
A. collina
, kindly lent to us by Marina Zerova, and found to be conspecific.
Diagnosis
. As for
A. balajasi
except that gaster is only 1.55–1.7× as long as high.
Biology
.
Aximopsis collina
has been found associated with
A. albus albus
,
an apparently ovipositing female being observed on an exposed seed in a fruit on
14.vi.
2011
in Dordogne,
France
, and it has been reared from fruits of an unidentified species of
Asphodelus
in
Turkey
, but its host relations on
Asphodelus
remain obscure. In both Mallorca, and on the Causse de Larzac (
France
),
A. collina
was reared in some numbers from, respectively,
A. ramosus
and
A. cerasiferus
, but no
Eurytoma asphodeli
were obtained from these samples. All emergences (
9 ♀
3 ♂
) have been in the first year of the fruits.
