03E99B66C751FFAEFF72C700FE14FC97.taxon	discussion	Notes: The small beetle was sieved near the upper part of the waterfall from material deposited near the banks, mainly wet leaves. The material obtained through a coarser beetle sieve (8 mm mesh size) was again sieved with a conventional kitchen sieve (2 mm mesh size) after several hours of drying.	en	Yin, Zi-Wei, Kleeberg, Andreas (2020): Description of Cerochusa gesinae sp. nov. from Thailand (Coleoptera: Staphylinidae: Pselaphinae).
