Tipula salicis Schrank, 1803 (nec Bouché, 1834; nec Fitch, 1845)
Cecidomyia salicis (Schrank, 1803)
Rabdophaga salicis (Schrank, 1803)
The name Tipula salicina was first coined by Schrank in 1781. However,
Schrank did not mention it again in his 1803 work, but lists a "Tipula
salicis". The description of both taxa (especially the small size and
black color of the imago, and the orange/red color of the larva)
suggests that his earlier Tipula salicina and his later Tipula salicis
may be identical. The name salicina has later been used by
Bouché
(1833) (but in the genus Cecidomyja (sic!)) who virtually copied the
original description of Schrank (1781), but (in error?) gave Meigen as
the original author. Other authors, beginning with Winnertz (1853),
have disregarded the earlier name salicina, obviously because it had
been abandoned by Schrank himself, and used the later name salicis; in
the
recent revision by Gagné (2004) the name Tipula salicina
Schrank, 1781 is not even listed. However, Bergenstamm and Löw (1876)
regard the two taxa as separate species, stating that the galls induced
in the Willow trees have different morphologies. To make things even more complicated,
the epitheta salicis and salicina have also been used by several other
authors for other species. However, Tipula salicina is definitely the
most senior name of all of these homonyms.
In my opinion, Bouche´s Cecidomyja salicina can confidently be
synonymized with
Schrank´s Tipula salicis (see also Winnertz (1853) and
Gagné (2004)). And because this Tipula salicis is very similar
to Schrank´s Tipula salicina, I suggest that these names can be
synonymized as
well. However, before this matter is not investigated in detail, also
incorporating data on the biology of the two taxa (e.g. salicina is
said to fly in May, salicis in July, and the galls are said to be
different) I provisionally list the two taxa as separate species.
