Tectosternum naviculare - male

Tectosternum naviculare - Male
Tippecanoe County, Indiana, USA
Size: ~ 1.5 mm
I found eight of these small hydrophilids in a berlese sample from 'fungus'. Fairly sure of ID, would welcome any confirmation/correction.

Sorry for the poor images, its hard with things this small.

ID confirmed...
via Smetana (1988)...although the details are difficult to discern, the ventral pic shows visible femoral lines on the metasternum, which together with the broad mesosternal process and locality data, secure Tectosternum as the correct ID.
