The Cave Trechines of the Genus Allotrechiama
(Coleoptera, Trechinae)
|
The
trechine beetles belonging to the genus Allotrechiama
are enumerated. In addition to the two species already known, two new
species
are described and illustrated : A.
dentifer from Shiratake-do Cave and A.
mandibularis from Kyusen-do Cave and Kuronita-no-tate-ana Pot. A
new
subgenus, Nothaphaenops is erected
for the latter species, which is one of the Japanese trechines showing
the
highest specialization for the subterranean existence. New localities
are
recorded for A. tenellus. |

A New Genus and Species of Cave-dwelling Cricket
from Luzon,the Philippines |
A new
cave-dwelling species of phalangopsid cricket belonging to a new genus
is described
and illustrated from a cave in Bontoc Prov., northern part of the
Island of
Luzon, the Philippines, under the name of Luzonogryllus
scotophilus. The new genus Luzonogryllus
is probably related to Parendacustes among the known genera, but
differs in the
number of spincs on hind tibia and more reduced elytral venation.

Three New Species of Subterranean Asellids from
Southern Kyushu and the Kii Peninsula, Japan |
Three
new species of the subgenus Asellus (Phreatoasellus)
are described from two
caves and a prospecting adit in western Japan. They are: A.
(P.) uenoi from Kyusen-do Cave, A.
(P.) iriei from Nozoe-no-ana Cave, and A. (P.) minatoi
from a
prospecting adit at Shimodaira. It is noteworthy that the distribution
of the
subgenus is restricted within the underground waters of the western
half of the
main islands of Japan, and that in one of the present three new
species, a pair
of the first pleopods, though sometimes ruditmentary, was observed in
four of
the seven females examined. |

Spiders from Tuff and Wave-cut Caves of Southern
Kyushu,Japan(I) |
The
spiders found in tuff caves and wave-cut caves of southern Kyushu are
dealt
with. They were collected by Dr. S.-1. UENO and Mr. T. IRIE in the
years
1971-1977, and are classified into twenty species, thirteen of which
are
definitely identified and listed in the present paper. Discussions are
made on
the variation shown by Leptoneta iriei
and on the presumable affinity of three undetermined species of Cybaeus. Of the remaining four, a Coelotes
cannot be identified at
present, while the other three are considered to be new species, the
descriptions of which will be given in the second part of this paper.

A New Subgenus and Species of Troglobiontic
Water-mite from New Zealand |
A
female of a troglobiontic water-mite, Uralbia
(Zelandalbia) hopkinsi subgen. et sp.
nov., is described from the cave water in
Upper Selenite Cave, Piopio, South Auckland, New Zealand. |

Environment and Microorganisims
Associated with the Formation of Moonmilk |
.The
environmental conditions under which moonmilk is formed were studied
with the
samples from the two caves, Uchimagi-do (Iwate Pref.) and Awoiwa-do
(Yamanashi
Pref.), Japan. It is forrned at a low temperature (8-lO'C) and in such
places
as are very close to the surface. The precipitate in the moonmilk
consists of
microcrystalline calcite (<lOÉ m),
of which the equilibrium PCO2 was calculated from the data of the
composition
of interstitial water. The PCO2 was about three times as high as that
of the
air. This seems to have been caused by the activities of
microorganisms. The
number of aerobic heterotrophic bacteria in the moonmilk amounted to 106/g
of the wet sample, and a high count of nitrifying bacteria was also
detected.
The microflora of the moonmilk mainly consisted of Gram-negative rods
and
seemed to be similar to those of fresh water. The bacteria isolated
from the
two samples had several physiological properties in common. Though
mechanisms
remain unsolved, the existence of microorganisms appears to be
indispensable
for the formation of the moonmilk. |

Discovery of Guano-minerals in Ambo
Limestone Cave of Peru |
A new
locality of guano-minerals is reported based on a specimen from Ambo
Limestone
Cave, Huanuco County, Peru. X-ray and chemical data are presented. It
is
suggested that the guano-minerals consist of brushite (CaHP04・2H20) and
gypsum
(CaS04・2H20). |
