SUPPLEMENTARY TABLE 1. Table of landmarks used for the geometric morphometric analysis. When the right cephalothoracic side was not preserved, the left side of the cephalothorax was digitised and the data were reflected.
| Landmark number | Description |
| Number 1 | Most anterior section of cephalothorax |
| Number 2 | Most lateral extent of right cephalothoracic edge |
| Number 3 | Most distal point of genal spine |
| Number 4 | Most posterior point of right ophthalmic ridge |
| Number 5 | Most anterior point of right ophthalmic ridge |
| Number 6 | Most anterior point of right interophthalmic ridge |
| Number 7 | Most right lateral extent of cephalothoracic-thoracetronic hinge |
| Number 8 | Most posterior point of right interophthalmic ridge |
| Number 9 | Most posterior point of cephalothoracic midline |
