Original description:
Galloisiana sinensis
Wang 1987
Upperside and head dark yellowish
brown; underside, legs and antennae pale amber. Body surface densely
covered with soft hairs, sparsely spinulate on the legs.
Head
large, as broad as pronotum, with an undefined black patch on the
center. Compound eyes smaller than antennal socket, elongate, pigmented.
Clypeus trapezoid, the anterior half pale membranous and translucent.
Labium semicircular, with anterior margin rounded. Maxillary palpi
5-segmented, with the first segment subquadrate, 2nd slightly elongate,
3rd as long as 1st and 2nd together, somewhat equal to 4th in length,
5th slightly longer than 4th, tapering slightly toward apex. Antennae
34-segmented, basal ones short and thick, 3rd segment about twice
as long as 2nd, from 4th to 9th each about as long as broad, 10th
to 19th distinctly longer, following ones each about 2-2.5 times
as long as broad.
Pronotum well-developed, slightly
longer than broad, sides nearly straight, slightly narrowed toward
base, hind angles broadly rounded, hind margin distinctly concave
in the middle; disk fairly convex, with a sinuate transversal sulcus
near the anterior margin. Mesonotum slightly shorter than broad,
much narrowed than pronotum at base, sides conspicuously broadened
posteriorly, hind margin concave. Metanotum transverse, about 1.7
times as long as broad, distinctly shorter than the mesonotum.
Abdomen
10-segmented, somewhat fusiform, broadest at middle, each segment
with one or two spinules near the hind angle. Apex of supra-anal
plate prolonged into a curved cylindrical projection.
Cerci
9-segmented, with basal two closely united, not clearly separated
from each other, 3rd to 5th somewhat equal in length, the rest slender,
especially the terminal one which is much thinner than the others;
each segment, except the basal two, bears 4-5 spinules arranged
in irregular ring near apex.
Anterior femora stout
and short, dorsal surface with two rows of spines (three or four
on each), the outer side smooth, the inner side with a lot of hairs,
beneath armed with 15-18 spiniform hairs on the inner margin; tibia
somewhat shorter than the femora, armed with two rows of spines
(4-5 on each) on the ventral surface, and two apical spurs of which
the inner one is longer than the outer but shorter than the first
tarsal segment; tarsi 5-segmented, 1st to 4th segments triangular
in dorsal view, densely pubescent beneath, each with a pair of membranous
pads at apex, 5th segment elongate, with a single membranous pad;
claws simple. Middle femora more slender than the anterior, sides
bear some spines; tibia as long as the femora and spinulate; first
tarsal segment longer than the anterior. Posterior legs with femora
much more slender than the anterior two; tibia slightly longer than
the corresponding femora, irregularly spinous; tarsi distinctly
elongate, first segment about equal in length to 2nd and 3rd together.
Left
coxite triangular, broader and larger than the right coxite, the
latter distinctly attenuate at apex, styli not very slender.
Body
length 12 ㎜; antenna 3 ㎜; head 3 ㎜; pronotum length 2.6 ㎜, breadth
2.3 ㎜; mesonotum length 1.7 ㎜, apical breadth 2.3 ㎜; metanotum
length 1.3 ㎜, apical breadth 2.3 ㎜; anterior femora 2.6 ㎜, ante-tibia
2.4 ㎜; midfemora 3 ㎜. mid-tibia 3 ㎜; hind femora 4 ㎜, hind tibia
4.3 ㎜; cerci 6 ㎜.
Holotype ♂, Jilin: Changbei
Shan, 2000 m, 28. VIII. 1986, Wang Shu-young.
Closely
allied to Galloisiana nipponensis Caudell et King, distingushied
by the pronotum with the hind margin concave in the middle; the
antennal segments less numerous with the terminal ones longer; the
anterior legs with slender femora, more densely spinous on inner
margin beneath; and the different conformation of supra-anal plate.
Also allied to Galloisiana kurentzovi Pravdin et Storozhenko from
Siberia, but in that species, the hind margin of pronotum is produced
in the middle.
The new species Galloisiana sinensis
described in this paper belongs to the order Grylloblattodea which
is previously unknown in China. It is based on a single specimen
collected from Changbei Shan, Jilin Province, N.E. China, and kept
in the Institute of Zoology, Academia Sinica, Beijing.
