The genome is 1.2 Mb, and it is, for most characteristics, very similar to the genomes of the other Rickettsiales, with two notable exceptions; the genome of " Midichloria mitochondrii " contains the gene sets for the synthesis of the flagellum and of a cytochrome oxidase of the cbb3 kind.

Fleas are related to the Diptera ( true flies ) and the Mecoptera ( scorpion flies ) as shown in the cladogram, based on a 2008 analysis of four loci ( 18S and 28S ribosomal DNA, cytochrome oxidase II, and elongation factor 1-alpha ) for 128 flea taxa from around the world.

The cells in V2 that are most strongly color tuned are clustered in the " thin stripes " that, like the blobs in V1, stain for the enzyme cytochrome oxidase ( separating the thin stripes are interstripes and thick stripes, which seem to be concerned with other visual information like motion and high-resolution form ).

These genera all show very long, toothed claws with a bulbous base, with one claw much longer than the other . " Dinochelus " has features in common with each of those genera; on the basis of DNA sequencing using cytochrome oxidase I, " Dinochelus " is thought to be the sister taxon to " Thaumostocheles " + " Thaumastochelopsis ".
