Hi everybody,
I'm struggling with the taxonomy of the two Dutch
Parallelomma species. When I look in the checklist by Beuk, I can see two species:
*
Parallelomma media Becker, 1894
*
Parallelomma vittata (Meigen, 1826)
When I look in the key from Ball (2007), Key to the British Scathophagidae (Diptera), two species are mentioned:
*
Parallelomma paridis Hering, 1923
*
Parallelomma vittatum (Meigen, 1826)
Of course it might be possible that paridis is another species that occurs in Britain, but not in the Netherlands, so I was also checking www.bladmineerders.nl. This is a website about all mining flies in the Netherlands. They mention two species:
Americina vittata and
Americina media. But when I look for the synonyms of Americina vittata, I find:
Chylizosoma vittatum; Parallelomma paridis (Hering, 1923); P. convallariae (Kaltenbach, 1873); P. beckeri Séguy, 1932; P. paucheti Séguy, 1932; P. hostae Hering, 1955; P. sasakawae Hering, 1955; P. albamentum Séguy, 1963.
So: we have a species called
Americina vittata synonym with
Parallelomma paridis, which is in the key from Ball together with
Parallelomma vittatum. I think this is really strange!!
Can somebody clarify this issue for me?:)
