This species can easily be distinguished from others in its range by the tubercles on the first femur of its first legs.[2] M. minuta has a body length of about 4 mm.

gollark: This seems really implausible? The only operation I can see a GPU doing for photos is scaling, for which the algorithms are pretty standard. Text rendering is trickier, though. Fingerprinting based on quirks in that with browser canvases exists, but I doubt this works on a low-resolution paper and it'll not tell you the GPU directly.

gollark: It's already too late.
