Amino acid matrices for phylogenetic analyses. (Matrices 1–3 were assembled according to minimum occupancy, matrices 4 and 5 are the reduced version of matrix 3, including only decisive orthogroups. In addition, for matrix 5, the orthogroups (OG) with the 20% fastest and slowest evolutionary rate (ER) were removed. Matrices 6 and 7 include only Malacostraca or Branchiopoda, respectively.)

	minimum occupancy per OG (%)	number of OGs	average occupancy per OG (%)	total aa positions	average missing aa positions (%)
matrix 1	75	81	80	17 690	21
matrix 2	66	232	74	59 929	27
matrix 3	50	864	62	242 530	40
matrix 4 (decisive)	50	455	63	122 993	38
matrix 5 (decisive, 20–80% ER)	50	267	63	75 776	39
matrix 6 (Malacostraca)	64	277	74	68 446	28
matrix 7 (Branchiopoda)	77	606	84	167 449	18
