Cyclosomus Latreille, 1829


Genus Cyclosomus Latreille, 1829 

Cyclosomus inustus Andrewes, 1924 

Redtenbacher (1867) and later Chaudoir (1876 c) misidentified the Hong Kong specimens of this species as Cyclosomus flexuosus Fabricius, 1775  . Andrewes (1921 a) questioned the identification of the Hong Kong specimens and after comparing 16 Hong Kong specimens from various collections described it as a separate species in 1924. In a letter dated 9 th June 1951, John Bowring wrote "I enclose a pair of a species of Cyclosomus  I met with yesterday morning for the first time. This beetle burrows to some depth in the sand by the sea-shore; it is very active in its movements, and when exposed on the surface disappears beneath the sand with truly wonderful rapidity, diving down head foremost. I captured about twenty specimens by turning up the sand for some distance to the depth of five or six inches." (Anon, 1851). Also listed for Hong Kong by Jedlièka (1963) and Bousquet (2003 i).
