Type species: Phycochus sulcipennis Lea, 1904, by monotypy.
|
| |
...... |
|
Diagnosis: Body globose. Clypeus granulate. Eyes greatly reduced. Flight wings
lacking. Elytral intervals margined at base. Metatibia with strong, complete median transverse carina. |
| |
|
|
Remarks: The most recent review of Tesarius was by Rakovic (1984). Except for T. sulcipennis, which
occurs in Australia (Tasmania) and New Zealand (Chathams) (Stebnicka 2001), all other described species are
native to western North America. This distribution seems unusual, and it is felt the genus needs further work
after more specimens have been collected in Australia. Being flightless and probably blind, they are not
attracted to light and must be sifted out of the sand dunes they inhabit. They can be locally abundant. |
