More Bolivian Rhinos - Need ID help

Here are two species of Rhinos I've found here in Bolivia. The first (first 2 photos)is rather common here and is usually around 4cm.

The second (last 2 photos) a monster of a beetle (8cm), have been showing up dead around my house lately. I've yet to find a live one .

Any help with IDs would be great.

¡Hola!

The first one is may be a Strategus sp. (maybe !)

The second one is a Megasoma actaeon male (80%)

Greetings,

Mashku.

I think the first one is either Strategus Validus or Strategus Longichomperus. the second one is Megasoma Actaeon
