Ununguitarsonemus tremulae
sp. n.
(
Figs 1–17
)
Diagnosis: Females, of the new species are distinguishable from those of all other species by subsurface dorsal nodules moved forward under prodorsal shield (PrS) rather than tergite C. They also differ from the most similar
U. peacocki
by
c
2
reaching almost to the posterior margin of its tergite, and setae
f
twice shorter than
e
. Apodemes IV reaching the edge of metapodosomal plate between trochanters III and IV ventrally, and setae
ag
in a distance of over twice their length. The new species differs also from
U. beameri
by
c
1
,
d
and
e
slender, attenuate rather than stiff and robust; and from
U. rarus
by the capitate sensilli and rounded lobe-like shape of tegula. Males differing from those known of two other species (
U. beameri
and
U. peacocki
) by dorsal setae
c
1
an
d
both attenuate, sharply pointed and located closely neighbouring each other; setae
e
less than twice shorter than
f
; tegula narrow, inscized terminally, femorogenu IV with very small subcircular adaxial protrusion and seta Fe
v’
separated from Ge
v’
by a distance of almost its two lengths. Larvae uniquely having their setae
sc
1
stiff, blunt, apparently shorter than
