Let me say that I have worked out <Episyrphus> species from India and =
the
Orient very carefully and with a lot of material. Chris Thompson (my
Smithsonian Advisor in 1982-83) knows this. One thing is very certain th=
at
what Chris Raper has from Malaysia (in alcohol--yuck !!) is most certainl=
y NOT
<balteatus>. In India, we have <balteatus> only in the north-west Himala=
ya
(Kashmir and Himachal Pradesh, maybe Uttaranchal and western Nepal also ?=
). =
In other parts we have <nectarinus> which is a eastern Himalayan and
Indochinese species, and <viridaureus> which is the widespread tropical I=
ndian
and Malaysian species. This distribution is the PATTERN which a good
biogeographer like Leon Croizat understood. What are the <Episyrphus> in=
your
bottle from Malaysia Chris Raper ????? Hmmmm ?????

Chris:
There is no question that Episyrphus balteatus is undoubtedly one of the
most widespread (naturally) flower fly. And it is one of the most variabl=
e
species as well as being migratorial. So, while most specialists agree th=
at
balteatus is widespread throughout the Palaearctic region, the status of =
it
in the Oriental remains unsettled. =
Brunetti once wrote "I have generally adopted the principle that anything=
that looks like balteatus, is balteatus." But others (de Meijere, Shiraki=
)
feel at least nectarinus (sterna with black fasciae, scutellum black pilo=
se,
etc.) and viridaureus (sterna with black fasciae, scutellum yellow pilose=
,
etc.) are separate species. =
I tend to go with the splitter and think we will at least in India and
probably Indochina that we have 3 "balteatus"-like species, but much more=
careful, controlled work must be done first to settle this, especially gi=
ven
the work Dusek & Laska did on the pattern variation. =
So, that's isn't the answer you wanted, but ...

Hi
I was wondering if anyone could tell me how widespread (around the
world) the common UK hoverfly Episyrphus balteatus (De Geer, 1776) is?
I have just received some Malaise trapped material from Malaysia - I'm
not particularly interested in the Syrphidae but I just notice one
looked strangely familiar...
Best wishes,
Chris R.

Dear Chris Raper,
<Episyrphus> is a predominantly Old World tropics genus and <balteatus>=
=3D
is
mainly Palaearctic, found also on the high Himalayas in the north-west (e=
=3D
=3D2Eg.,
Kashmir). I have described a few NEW species from the Indian sub-contine=
=3D
nt
and am now working on the other Oriental species. Your Malay specimen(s)=
=3D
that
look "strangely familiar" need to be properly identified. Its sister-gen=
=3D
us,
if one can call it that, is again the Oriental <Meliscaeva> which is also=
=3D
very
diverse in the Indian sub-continent, several NEW species being described =
=3D
by
me.
I would be glad to identify your specimen(s) and send you related datab=
=3D
ases.
Regards,
Dr KUMAR GHORPADE
