Differential diagnosis
. Among species of complex A the new species is closest to
Harpyrhynchoides metropelia
(
Fain, 1972
)
. In females of both these species, genua I and II have three setae each, femora I and II have two setae each, proximal segments of legs III and IV have a single seta each, distal segment of leg IV has three setae, and the idiosomal venter lacks scales or verrucosities and is almost fully striated. These species differ from each other by the following character states. In females of
H. zenaida
sp. nov
.
, setae
h1
and
h2
are subequal (vs.
h1
about seven times longer than
h
2
in
H. metropelia
), the posterior margin of the dorsal shield is straight (vs. widely convex); in males, setae
g2
are situated equidistant from setae
g1
and
g3
(vs. setae
g2
more three times closer to
g1
than to
g3
), the aedeagus is strongly curved (vs. straight), solenidion
ω
1
I is strongly thickened, at least twice thicker than solenidion
ω
1
II (vs. solenidia
ω
1
I and II subequal), and setae
vi
are about 90 long (vs. 42 long).
