PACIFIC SCIENCE, Vol. VIII, January, 1954 
DIAGNOSIS: Palpal femoral, genual, and lat- 
eral and ventral tibial setae nude; dorsal tibial 
seta feathered. Palpal claw three-pronged. 
Galeal seta feathered. Cheliceral base with a 
few punctae. Scutum with rear corners slightly 
rounded. Sensillary bases in advance of a line 
connecting posterolateral setae. Two crescent- 
shaped lines near the anterior margin of the 
scutum. Dorsal setae formula: 2-8-6-6-6- 
4- 2. Scutal measurements of a specimen from 
southern Korea: AW-65, PW-71, SB-31, ASB- 
22, PSB-13, AP-24, AM-42, AL-40, PL-61, 
5- 64. 
DISTRIBUTION AND HOSTS: Previously re- 
corded only from North America (see com- 
ments below), from various kinds of bats. 
In Korea T. myotis is known from Tobang-san 
from Myotis sp. 
TYPE DATA: Cotypes from Myotis lucifugus, 
Mt. Katahdin, Maine, U. S. A. Deposited in 
the U. S. National Museum. 
COMMENTS: Fuller (1948, Brooklyn Ent. 
Soc., Bui. 43: 106) has pointed out the sim- 
ilarity between T. myotis Ewing, 1929, and 
T. russica (Oudemans, 1902) of the Old World. 
We have not had the opportunity to compare 
our Korean specimens with russica, but they 
are very similar to North American specimens 
of T. myotis and, in our opinion, are not more 
than subspecifically distinct.

Obozr. [Moscow] 30: 157. 
DIAGNOSIS: All palpal setae nude (except 
setae on palpal thumb). Palpal claw three- 
pronged. Galeal seta branched. Coxal setae 
1-1-1. Sternal setae 2-2. Nude setae on tarsi 
I and II and leg III as illustrated; spur on 
tarsus II slightly longer than that on tarsus 
I. Scutum rather rectangular, with the rear 
corners angulate, and the rear margin slightly 
undulate. Sensillary bases in advance of a line 
connecting posterolateral setae. Bases of sen- 
sillae nude; sensillae with scattered branches 
on the distal half. Scutal measurements of a 
specimen from southern Korea: AW-59, PW- 
78, SB-25, ASB-28, PSB-10, AP-28, AM-36, 
AL-28, PL-38, S-47. 
DISTRIBUTION AND HOSTS: Previously re- 
ported only from the original collection. In 
Korea this species has been collected from 
Myotis sp. from Tobang-san. 
TYPE DATA: From Vespertilio superans from 
Mt. Voroschilov, U.S.S.R. 
COMMENTS: T. subakamushi resembles in 
some respects T. insolli Philip and Traub, 
1950, a species described from bats from 
Selangor, Malaya, but the two are clearly 
distinct species: In insolli the galeal seta is 
nude and the scutum is approximately as long 
as wide.

Parasitology 40(1, 2): 51. 
DIAGNOSIS: All palpal setae feathered or 
branched. Galeal seta feathered. Cheliceral 
base and segments of palpi dorsally with 
numerous small punctae. Scutum rounded 
posteriorly; sensillary bases behind a line con- 
necting posterolateral setae. Sensillae nude 
basally, with eight or more branches distally. 
One pair of humeral setae. Three mastitarsalae 
III. Scutal measurements of a specimen from 
southern Korea: AW-60, PW-73, SB-25, 
ASB-27, PSB-35, AP-17, AM-39, AL-42, 
PL-49, S-6L 
DISTRIBUTION AND HOSTS: Previously 
known only from Japan. This species is ex- 
ceedingly common in many localities in 
southern Korea and was taken mostly from 
Rattus rattus and R. norvegicus. 
TYPE DATA: Holotype from Microtus monte - 
belloi, Okiage Village, Yamagata Prefecture; 
September 17, 1920. Deposited in U. S. 
National Museum.
