Original description:
Galloisiana magnus
Namkung 1986
Male (holotype): Body larger than
any other Galloisiana
so far reported in the world. General coloration reddish brown,
head and pronotum slightly darker. Head round and flat, somewhat
chestnut like, smooth brown surface covered with fine yellowish
white hairs. 7-8 setae at the lateral margins, 4-5 near the antennal
socket. Frontal suture clearly seen from antennal base to occiput.
Eyes invisibly degenerated. However, under microscopic study, a
lighter spot with narrow oval shape and a pair of setae on the spot
are observed in the area of eyes. Antenna filiform with 52 segments
(the right one of the holotype broken). The third segment longest,
about 2.5 times longer than the second. Clypeus pentagonal, somewhat
bulged, noticeably subdivided by ots colour with darker posterior
and lighter anterior. Labrum semicircular with round anterior, whole
surface covered with yellowish-brown bristles. Lacinia with two
well spaced preapical teeth and a row of sparsely arranged long
stiff bristle on the inferior part. Pronotum nearly rectangular,
slightly narrowing posteriorly, 12 setae along anterior margin,
5-7 along lateral margins, while only 2 on the middle of posterior
part.
Mesonotum trapezoidal, distinctly narrowing
anteriorly. 5 brown setae on left and 4 on right side, and 8 along
posterior margin. Metanotum similar to mesonotum in shape. 3-4 setae
on the fore parts of lateral margins, 10 along posterior margin,
and 6 irregular ones on the middle. 8 pairs of long spine-like setae
on the first cervical sclerite, regularly arranged along the lateral
margins. Basisternum elongated triangularly, nearly sclerotized,
slightly narrowed posteriorly.
Abdominal tergites
with 8 setae along posterior margins, and one pair on the mid-lateral
sides of each segment. Supra-anal plate bulged, somewhat pig-nose
like in shape, and it is a diagnostic characteristic of this species.
Abdominal sternites with irregularly arranged numerous setae. Cerci
with 10 segments (tip of right one broken). 4-6 setae at posterior
end and long fine hairs at outside of each segment.
Legs
long, length/ width ration of femur and tibia are: 4.07 and 5.33
respectively in fore legs, 4.18 and 6.56 in mid legs, 5.36 and 8.87
in hind legs. Femur and tibia with numerous setae, and a horn-like
apophysis on tibial tips. Tarsi with well developed white pulvilli.
Gonocoxite
asymmetrical, left gonocoxite scoop-shaped with its basal part about
twice as wide as that of right one. Right gonocoxite longish triangular
with a short thumb-like process inwardly bent on median dorsal margin.
Stylus cylindrical, five times longer than wide with 4 long setae
(2 on apex and 2 on inferiorly).
Left phallomere
bulged, somewhat sclerotized, and with a large eversible sac which
is elongated, nearly membranous and wrinkled. Right phallomere nearly
transparent, with a large distal principal copulatory sclerite which
is covered with a sclerotized plate and tip of which is bifurcated
and bent.
Measurements (㎜): Body length (from clypeal
suture to the insertion of cerci) 38.50; Head length 5.10, width
5.86; Antennal length 20.00; Clypeal length 1.63, width 2.14; Labral
length 1.12, width 1.53; Pronotal length 5.87, width 5.20; Mesonotal
length 4.34, width anterior 3.32, posterior 5.10; Metanotal length
3.83, width anterior 3.67, posterior 4.95; Abdominal length 18.00,
width 4.69; Cercus length 19.20; Fore leg length 17.70 (5.60, 4.08,
5.46); Mid leg length 19.80 (5.76, 5.35, 6.43); Hind leg length
24.90 (7.65, 7.24, 7.24).
Remarks: This new species
is similar to G. biryongensis
Namkung, 1974 in general appearances. However, it is distinctly
different from the latter with its pig-nose like bulged supra-anal
plate and its bifurcated principal copulatory sclerite, while G.
biryongensis has a tip of fountain-pen
like supra-anal plate and a simple undivided principal copulatory
sclerite.
Female: Unknown.
Type specimen:
Holotype male, collected by Young-Kyu Kim on May 4, 1986.
Type
locality: Badgudok-gul, a lime stone cave in Badgudok village of
Munung-ri, Nam-myeon, Chongson-gun, Kangwon-do, Korea. The cave
is situated at the mountain side (altitude 900 m), near Badgudok
village which is located at upstream of the Southern Han-River,
about 200 ㎞ east from Seoul, and 20 ㎞ south-east from Biryongdong-gul
cave which is the type locality of G. biryongensis.
The type specimen was found tumbling on the surface of a small puddle
about 40 meters below from the entrance of the cave.
Etymology:
The specific name magnus
(L: large) is based upon "large sized body" of the new
species.
