Derivation of species name:
This species is named ‘pseudostriatolateralis’ after its similarlity to
S. striatolateralis
as a second species with the distinctive microstriate lateral pronotal flange.
Natural History:

1150 and
1850

Comments:
This species is very similar to
S. striatolateralis
but the latter has a blunt tooth on the front femora, few if any elytral setae and different male genitalia.
