We (Dmitry Gavriushin and me) thought so. But seems it is not Blephariceridae.
New idea:
Thaumaleidae comprise a homogeneous family of
small (wing length 1.5-7.5 mm) (Fig. 1) stoutly built flies
with shiny yellow to black bodies. Their eyes are
holoptic in both sexes, their antennae short and slender.
The wings have a characteristic venation and tend to
fold downwards across a transverse line of weakness
near the apex of the subcosta. The adults are diurnal
and usually frequent wet rocks or vegetation near
streams in wet forest. The larvae are aquatic and
amphipneustic. The family (about 100 described species)
is possibly mainly holarctic in distribution with less than
a dozen species having been described previously from
the southern hemisphere.
