Found it on my son's hair after a 10min visit to our veggies garden. My guess is that it might be a tick but we are not in an area of lime disease and although it's an open, rather unkept, field the only mammals I see around are 2-3 stray(?) cats.
The photo was done using a stereoscope+smartphone. The dark lines underneath are .4 to .5 mm.
Any pointers would be welcome.
A tick for sure. Which species I don't know. Whereabouts in the world is this veggie garden?
Also, ticks often climb to trees or tall grasses and let themselves fall when they sense a potential host underneath. I doubt your kid got it straight from the cats, and as for mammals- you see cats, but are you sure you don't have any foxes, raccoons, rats, bats, kangaroos, possums, deer, squirrels, dogs... ?
My veggies garden is in the litoral north of Portugal.
I'll second southsamurai and agree with Rhipicephalus sanguineus, the brown dog tick. Shape of the capitulum checks out, it has visible eyes, similar body and so on.
Visible eyes? Capitulum? Would not know where to look for that. Is there any online resource where I can learn on that?
Also! Might be a bit late now, but I would recommend a thorough search for other ticks on your child. I've found ticks on myself a few times and it's never pleasant, these buggers latch onto your skin and you don't feel them.
You might need a very strong repellant the next time you go into the garden, the DEET ones are effective against ticks. Apply on the neck, waist and shoes as well as on any other exposed skin areas. Stay safe!
Wikipedia is a good starting point, then you have this

And you can also search online for how to ID ticks, you have visual guides and such
Thanks! Had seen that paper once you guys pointed me to R. sanguineus and I had a chance to shower the kid.
I also found this site useful for ticks anatomy, on TicksSafety.com.
