Fixsenia pruni (Linnaeus, 1758)
Note: The genus Satyrium has previously been divided into a number of
genera of doubtful monophyly (e.g. Strymonidia, Nordmannia). Based on
the morphology of the genitalia (mainly the presence or absence of a
ventral keel of the aedeagus) Clench (1978)
synonymized most of these genera with Satyrium. Only the genus Fixsenia
was retained for the present species and a few other hairstreak
species. The hairstreaks are a group of Lycaenid butterflies of
insufficiently studied relationships and no comprehensive phylogeny is
available. They thus have a history of frustratingly unstable taxonomy
illustrated by the multiple genus assignments of most species and a
lacking consensus among authors on the correct genus placement of most
species.
I think it is of paramount importance to bring about nomenclatural
stability for this group of animals. In the unfortunate absence of a
modern study of hairstreak phylogeny that uses all available methods and
data, I will recognize only
genera that have a high likelihood of being a monophyletic grouping, and
therefore, in all likelihood, will not have to be changed after future
phylogenetic studies. Fixsenia might be a monophyletic taxon, but there
is no comprehensive test so far. In addition, the species Satyrium spini
is in many external characters intermediate between typical "Satyrium"
and typical "Fixsenia" (e.g. the black band on the hindwing underside is
partially resolved into black spots and the anal angle has a large
field of blue scales) and I suspect that these similarities that mediate
between the "genera" are indications of a paraphyletic nature of
Fixsenia. Therefore, I regard both genus names as synonyms and place all
species in a hopefully monophyletic genus Satyrium.
Additional German name: Pflaumen-Zipfelfalter.
