Materials and Methods
The pselaphine specimens were collected by
the following four collecting methods: light trap
(LT), flight intercept trap (FIT), quantitative sampling
using Tullgren funnels (TL) and hand sorting
(HS) of leaf litter and decayed wood.
Two sets of portable light traps (4W) made by
Mr. Yuta Nakase (Fig. 121C) were used for collecting
pselaphines.
Many pselaphine species were collected by a
new type of FIT named NG-5 (Fig. 121D). Thenew type is the same in size and shape of the barrier
as those shown in Nomura and Idris (2004)
(NG-3), though it has a roof along the upper margin.
The quantitative sampling was made as follows:
1) a quadrat sized 1 m1 m was set on the
ground; 2) leaf litter inside the quadrat was gathered
by hand; 3) the litter was sifted using a sifter
(Fig. 121E); 4) the sifted litter was set into Tullgren
extractors with 40% ethanol hydrate;
5) soil beetles were extracted within 48 hours
lighting; 6) the extracted soil beetles including
pselaphines were sorted, identified and counted;
7) the materials were preserved in 75% ethanol
hydrate.
Some specimens were collected by hand sorting
(Fig. 121F), namely sifting leaf litter and
checking under bark and decayed wood.
Collected specimens are shared by the insect
collection of the Department of National Parks
(DNP), Bangkok, Thailand and that of the National
Museum of Nature and Science, Tokyo,
Japan.
