Only if the few remaining members of a species were located directly in the path of the lava flow.

Explanation:

Generally, you can have "mass deaths" due to the large swath of habitat that can be covered in huge lava flow. But unless the extent of eruption was essentially continental, the extinction of any particular species is not likely.
