It's in the genus Automeris, but I'm not sure which species it is. Perhaps someone here who is more familiar with South American Saturniidae would be able to identify it. This genus is quite large - en.wikipedia.org/wiki/Automeris

Malo said "(also the tip of her thorax seems to be ruptured, and the eggs are still there)" I assume you mean "tip of her abdomen". If the eggs are coming out of a hole in the top, side or bottom of the abdomen they will be infertile. They have to pass through the genital opening to be fertilised. However, many Saturniids may have a clump of eggs stuck to the abdomen near the genital opening. If the moth was sitting somewhere it may have continued to lay eggs which did not drop off the tip of the abdomen. One word of warning, I seem to remember that some Automeris larvae can be highly irritant, so be careful when rearing them. Adam.

Adam. abdomen, right, always confuse the two. and i'm not entirely sure, but i saw a clump of eggs stuck to a green substance coming from the side of it, i could try and take a picture if you want, it looks like damage to me but i'm not entirely sure, she hasn't laid any eggs since. also thanks for the info, i had been researching earlier about their larvae and they are pretty dangerous, i'll be as careful as possible when(and if) they hatch

Indeed, the venomous spines of Automeris caterpillars have a painful sting, the severity of which possibly varies depending on species, and also of course depending on how sensitive an individual is to the venom. The sting of the caterpillars of another genus of saturniid moths, Lonomia, is known to produce even more dangerous systemic effects, especially that of Lonomia obliqua. Statistically, it is considered to be the most dangerous caterpillar in the world. The caterpillars move around gregariously in large groups, increasing the chances of multiple stings, and therefore a greater danger to health.

If you put leaves in the container the eggs will die. If they are fertile after they hatch you can then gently transfer them onto leaves. It is best to use a soft paint brush, but do not push them, it is best to let them crawl onto the brush. Particularly as they grow it is important never to pull the larvae off leaves or branches when you change the food plant in the box. Saturniind larvae have rather fragile legs, and pulling them off whatever they are holding them can easily kill them. If the eggs were on the tip of the abdomen they are likely to be fertile, but if they came from a wound on the side of the abdomen they will be infertile. Probably after about a week infertile eggs will collapse inwards, whereas fertile eggs should retain most of their shape but may appear a little dented (concave) on the sides, not really collapsed. I don't know how long it takes for Automeris larvae to hatch but many Saturniids hatch within 2 weeks, some take a lot longer. Adam.

Adam. thanks a lot for the info, i'll try my best to keep them. as for the species, i'm thinking it might be Automeris Illustris, common in my region as far as my research went and also the most similar looking one i could find

In your photo of your Automeris eggs, the egg micropyle looks greenish. The micropyle will eventually turn black if the eggs are fertile.

the micropyle can take about a week to show black, maybe sooner. Automeris ova can take longer than other Saturniidae to hatch,sometimes 3 weeks or more. The best thing is the micropyle indicator, once it's black, the eggs are fertile, then you just wait.
But like Adam mentioned- the eggs need to pass through the abdomen tip to be fertilized.
