Original description:
Galloisiana kosuensis
Namkung 1974
Male
holotype: Size medium for the genus.
Head: Uniformly
reddish brown, flat and somewhat wider than long (4.0 to 3.7 ㎜).
There are fine yellowish-white hairs on all smooth surfaces. The
cranial line is not clear. There are four setae on the left side,
six on the right, three each at the place where the antennae are
attached, seven in irregular spaces along the hind margin.
Clypeus:
1.3 ㎜ in front, 1.5 ㎜ at back, 0.8 ㎜ in height. The front half
is membranous and the postclypeus is sclerotized.
Labrum:
Semicircular, rounded in front, somewhat wider than long (0.8 to
0.6 ㎜). with seven or eight weak setae on the surface.
Eyes:
Small in size with each containing an ocular seta in the center.
Antenna:
46 segments on the left, 45 segments on the right. The third segment
is approximately three times longer than the second one.
Maxillary
palpi: Labial palpi and Lacinia are similar to Galloisiana
biryongensis in form.
Pronotum:
Gently narrowed from anterior to posterior and longer than wide
(front 4.0 ㎜, back 3.6 ㎜, length 4.3 ㎜). Seven setae on the promargin,
with one pair of large spines on each side. Three setae on the left,
two on the right side, seven or eight weak setae spaced irregularly
in the middle.
Mesonotum: The front narrower than
the hind margin (front 2.7 ㎜, back 3.6 ㎜, length 2.7 ㎜). Width
of the back is same that of the pronotum. There are three setae
on the left side, four on the right, five on the hind margin, and
five positioned irregularly in the center.
Metanotum:
The promargin slightly shorter than the retromargin (front 3.1 ㎜,
back 3.3 ㎜, length 2.2 ㎜). One seta on the left, one seta on the
right side of the retromargin, and seven setae on the front half.
Sternum:
The first cervical sclerite has four spine-like setae on each side,
there are distinctly V-shaped and partially sclerotized below.
Abdominal
tergites: The first tergum is not clearly visible, as it is sandwiched
under the metanotum. The 2-8th have eight large setae, 9th seven
setae on each side of the retromargins, and one pair of seta on
each of the lateral sides. The 4th tergum is the widest and nearly
as wide as the retromargin of the metanotum. The supra-anal plate
forms an asymmetric triangle, the left side is inclined and its
apex is dull pointed, and bent inward. This is a distinguishing
character from the closely related species, Galloisiana
biryongensis, which has a dull point of
fountain pen in shape.
Abdominal sternites: Have
numerous setae on each of the plates spaced rather irregularly.
Cerci:
With nine segments. Which are colored with yellowish-white fine
hairs throughout. Five large setae at the end of 1-5th segments,
four at 6-7th segments, three at 8th segment, two at 9th segment,
and long, white fine sensory hairs at the outsides. The second segment
is the shortest, 6th and 7th segments are the longest.
Legs:
The ratio of length divided by width is as follows: The anterior
femora 2.36; the middle one 1.70; the hind one 1.83; The anterior
tibia 3.75; the middle one 3.91; the hind one 5.09. The tarsi have
white pulvilli as in G. biryongensis.
Leg-formula: 3.1.2 (18.9 ㎜, 15.7 ㎜, 15.4 ㎜).
Male
genital organ: The right coxopodite is acutely triangular in shape,
longer than wide (7:5). Rarely visible a short thumb-like process
sandwiched and bent inward near the base of the dorsal margin. The
left coxopodite is a scoop-shaped structure wider than long (13:8).
The style is five times longer than broad and bears exceptionally
long setae; two on the apex, and two large ones at the inferior
side. The left phallomere is supported by the sclerotized skin and
has a weak white eversible sac, which is nearly entirely membranous
and multi-wrinkled in appearance. The right phallomere is nearly
completely membranous and transparent and practically invisible.
The principal copulatory sclerite differs from G.
biryongensis in that it has the pick shaped
apical lip of copulatory process, a souter hook-like processes on
the dorsolateral side.
Coloration: General coloration
reddish brown, head and pronotum noticeable darken.
Measurements
(length in millimeters): Body about 22; antenna about 15; cercus

Female: General form is similar to
the holotype (♂). Head: length 4.5 ㎜, width 4.8 ㎜. Antennae:
47 segments in the right. Pronotum: Anterior width 4.3 ㎜, Posterior
width 4.0 ㎜, length 4.4 ㎜. Mesonotum: Anterior width 2.9 ㎜, Posterior
width 4.0 ㎜, length 2.8 ㎜. Metanotum: Anterior width 3.3 ㎜, Posterior
width 3.8 ㎜, length 2.0 ㎜. Abdomen: Length 9.7 ㎜, width 4.2 ㎜
(4th sterna). Without setae on the abdominal tergites but 6-11 setae
arranged on each of abdomen plates. Leg-formula: 3.1.2 (18.8 ㎜,
14.8 ㎜, 13.8 ㎜). Cerci: broken five segments. Ovipositor: The
dorsal valve (4.5 ㎜) of the ovipositor reaching to 3/4 of 4th cerci
segment, apex acute; middle valve (2.8 ㎜) attached basally to dorsal
valve at 2/15 the distance from the latter's base.
Type
specimen: Holotype ♂ (4. XI. 1973, collected by J. Namkung). Paratype:
♀ (29. XII. 1973, collected by B.S. Eom), 1 young ♂ (4. XI. 1973,
collected by J. Namkung). The new species type is deposited in the
author's collection.
Type locality: A lime-stone
cave calle "Kosudong-gul" at Kosu-ri in Daegang-myeon,
Danyang-gun, Chungcheongbuk-do, Korea.
