A New
Aphaenopsoid Thechine Beetle from South Korea
|
A
remarkable aphaenopsoid trechine beetle is described from a limestone
cave of
South Korea under the name of Gulaphaenops
leptodiroides gen. et sp. nov. It belongs to the Trechoblemus
series, and though strikingly modified in general appearance,
is related to the genus Ishidatrechus
of Central Japan.

Two New
Subterranean Lathrobium (Coleoptera, Staphylinidae)
from Japan
|
Two new staphylinid
beetles belonging to the genus Lathrobium
are described from the upper hypogean zone of West Japan. One of them, L. daisenense, was obtained
on Mt. Daisen in Tottori Prefecture, and the other, L.
tosanum, was found in Hongawa-mura of
Kochi Prefecture. |

Nesticid
Spiders (Araneae, Nesticidae) from Kyushu,
Japan |
Nesticid spiders are recorded
from Kyushu in Japan. As the result of
my examination of 430 specimens of Nesticus,
they are classified into ten species, of which eight are long-legged
and two
are short-legged. All the long-legged species belong to the akiyoshiensis
type, i.e. the western
Japanese type. One of them from Nagasaki Prefecture is new to science,
and is
described under the name of Nesticus yaginumai.

A NeW
Spider, Coelotes
acco (Araneae, Agelenidae) from an Abandoned Mine of the Boso
Peninsula,
Central Japan |
A new agelenid
spider is described from an abandoned mine adit on the Boso Peninsula,
Central
Japan, under the name of Coelotes acco.
lt is closely allied to C. interunus,
but can be readily recognized on the peculiarities of sexual organs in
both the
sexes. |

Two New
Species of Epicrius (Acarina, Epicriidae) Collected by
Driven Traps in Japan
|
Two new
mites of the genus Epicrius belonging
to the gamasid family Epicriidae are described from Japan under the
names of E. omogoensis and E.
parvituberculatus. They were collected by traps driven into the
ground. |

A New Neoparasitus
and Hypoaspis queenslandicus
(Acarina, Gamasida) Collected from the Subterranean Domain of Japan
|
A new neoparasitid
mite belonging to the family Rhodacaridae is described under the name
of Neoparasitus punctatus. lt was collected
by means of driven traps. Besides, Hypoaspis
queenslandicus (WOMERSLEY), found in baited traps in a limestone
cave, is
newly recorded from Japan.

ESR
Ages of Paleolithic Site of Douara Cave, Syria |
The ages of
teeth, bones and eggshells which were excavated at a Paleolithic site,
Douara
Cave in Syria were determined using electron spin resonance (ESR). The
teeth
and bones were measured in their prototype without destructive
pretreatment.
The total dose of natural radiation was estimated using the ESR signal
of CO33-
radicals (gÛ=2.0024,
gll=1.9977) for teeth and bones
and the ESR signal of radicals (gÛ=2.0016,
gll
=1.9981) for eggshells. The ESR ages were obtained using the uranium
contents
in the samples determined by secondary ion mass spectrometry and in the
surrounding soils reported earlier. The ESR ages are consistent with
the
fissiontrack age. |

A
Device of Fluorescent Dye Detection |
An
introduction of the method of activated charcoal and standard potassium
hydroxide-isopropyl alcohol mixture by ALEY and FLETCHER (1979) and a
simple
device of the detection are briefiy described from a practical view
point. The
extract solution may be often strongly dyed yellow, probably caused by
some
organic acids. As the result,it may be difficult to notice weak
fluorescence by
naked eyes. If it is so, add some grains of potassium hydroxide and
stir up.
Limpid alcohol solution with fluorescent dye is separated and the
fluorescence
can be easily recognized by naked eyes. |
