Could this be Xanthempis digramma?
What is the difference with X. punctata?

Hi,
This is E. digramma.
E. punctata has ordinary thoracic setation and thorax viewed from above almost entirely blackish-grey, with a duller black median stripe and two shorter and somewhat broader stripes at sides, in anterior view the lateral stripes invisible.
