Taxonomic note.
J. Villeneuve described
Phaonia canariensis
from
2 females
from Gran Canaria (leg. R. Frey). My examination of
18 specimens
of both sexes (leg. R. Frey, R. Storå) from Gran Canaria and Tenerife recorded as
Phaonia sordidisquama
in
Frey (1936)
revealed that
15 specimens
represent misidentified
P. canariensis
. Hennig (1963a, 1978) pointed out the close relationship of
P. canariensis
with
P. signata
. However, it is morphologically even closer to
P. tuguriorum
as presently understood and apparently inseparable from that species on other than substantial differences in colour.
Material examined.

Description.
Only striking differences in colour apparently separate the Canarian
Phaonia tuguriorum canariensis
from the nominal subspecies,
P. tuguriorum tuguriorum
: Antenna and palp black, often more brownish on basal antennal segments; frons, face and parafacials dark brown pruinose; thorax very dark greyish pruinose with distinct pattern of brownish black mesonotal stripes; scutellum wholly dark or translucent brown at extreme apical part; posterior spiracle with dark brown fringe contrasting with pale brown fringe of anterior spiracle; calypteres brownish black infuscated, concolorous with wing base; shadowing of cross-vein r-m and d-m less distinct, especially among the males; femora and tibiae wholly brownish black, or posterior tibiae ochre brown; abdomen black, covered in bluish grey pruinosity delimiting a median black stripe becoming narrow or obsolete on tergite VI.
Distribution.
An endemic western Canarian subspecies known so far only from Gran Canaria and Tenerife.
