Mosquito mech is a perfect name, really. But if you want to change the name, simply take a random number with no more than three digits and put the letter "M" in front of said number. (Add an "X" next to the first letter if it's experimental.)
I think the model should be called the Thunderblood Assault Mech (TAM). The jagged purple/black etchings & the bright yellow main color remind me of lightning, & I can definitely see this mech ripping through enemies before you can blink. It could also be a stealth model with a different color scheme.
