(in part). Misidentification.
Etymology.
Named after Masaaki Suwa (Sapporo,
Japan
) in recognition of his outstanding taxonomic work on East Palaearctic and Oriental
Anthomyiidae
.
Description.
Very similar to
Egle minuta
but different as follows:
Male.
Terminalia (
Figs. 170–175
): Sternite V with 0–1 setula postero-laterally on basal plade. Epandrium without setulae on lateral parts (as in
E. parva
and
E. lyneborgi
). Surstyli narrow-based alongside margins of cerci (as in
E. parva
and
E. lyneborgi
). Apical extension of cerci broader, not constricted on basal part. Pregonite wider than long. Phallus with smaller and apically less inflated epiphallus.
Female.
Specimens presently identified as
Egle suwai
are almost indiscernible from females of
E. lyneborgi
. Only the oviscapt (
Fig. 199
) reveals a few minor differences: Sternite VII as narrow as in
E. minuta
, but sclerotized even on middle section as in
E. lyneborgi
. Hypoproct more reduced than in
E. minuta
, but less so than in
E. lyneborgi
and with 3–4 setulae.

Biology.
The adults have been taken in
Denmark
on flowering Grey willow (
Salix cinerea
L.).
Distribution.
Presently only known by the
type
material from
Denmark
and south
Sweden
, but
Egle suwai
has obviously been confused with other species of the
E. minuta
species group. A wider distribution in Europe and possibly elsewhere can be expected.
Relationships.
Egle suwai
belongs to the
E. minuta
species group within the
E. minuta
section (see above).
