ground color brownish yellow, patterned with darker brown,
colors not conspicuously contrasting as is usual in the subgenus;
costal and cubital darkenings and a transverse band on cord
present; basal third of cells C and Sc more yellowish; basal third
of cells R and M extensively darkened, more or less confluent
with a broad seam at origin of Rs; a darkened cloud at outer end
of cell 1st M2; veins brown, Sc yellow. Venation: Cord subtransverse to weakly oblique; Rs angulated to spurred at origin;
m-cu close to or beyond fork of M. In one paratype cell M2 of
both wings open by atrophy of m.
Abdominal tergites gray, with two dusky longitudinal sublateral lines, broken by broad ochreous posterior borders of
segments, lateral borders more narrowly pale; sternites yellowish gray; hypopygium dark gray. Male hypopygium (Plate 2,
fig. 34) with basistyle, b, unarmed with spines but with numerous elongate setre. Dististyle, d, with outer angle produced
into a strong spine, apex acutely pointed and blackened; inner
lobes much as in baikalica. In the latter species the apical
margin of the basistyle bears a group of several stout black
spines; outer margin of dististyle scoop-shaped, obtuse at apex,
not blackened or produced into a spine.
Habitat.-Northern Korea.
Holotype, male, Chonsani, Paiktusan, altitude 4,650 feet, July
17, 1937 (Yankovsky). Paratopotypes, 4 males, altitude 3,800
to 4,650 feet, July 17 to 19, 1937 (Yankovsky).
In the nature of the wing pattern, Pedicia (Pedicia) simulata
is surprisingly like the Siberian P. (P.) baikalica (Alexander),
but differs conspicuously in the details of structure of the male
hypopygium, especially the dististyle, which is acutely spined,
as is commonly the case in the subgenus Pedicia. The series
of small-sized members of the subgenus Pedicia in eastern Asia,
including baikalica, cubitalis Alexander, gaudens Alexander,
grandior Alexander, and subtransversa Alexander, show a perfect transition in characters between those formerly accepted
as distinguishing Pedicia from Tricyphona. These characters
in Pedicia include major physical size, the nature of the wing
pattern, obliquity of the cord, and presence of a primary spine
on the outer angle of the dististyle of the male hypopygium.
All of these characters break down in the series of small-sized
species listed above, and it is very evident that it will be almost
impossible to differentiate Tricyphona from Pedicia except as a
matter of convenience in handling the complex of included forms.
