I tried the following path: 

 melipona <- paste(system.file(package="dismo"), "/ex/Melipona.csv", sep=";")

The file Melipona.csv is not located in the C:/Users/N1na3/Documents/R/win-library/3.4/dismo/ex/ directory. I have listed the contents of this directory on my computer and there are only two .csv files, called acaule.csv and bradypus.csv . 

$ ls /Library/Frameworks/R.framework/Versions/3.4/Resources/library/dismo/ex/

As I do not have access to your computer, I can only speculate on a possible solution to your problem. Do the following:

1) Copy the file Melipona.csv to somewhere known within your computer. For example, a Documents / Dissertation / Melipona / Analyze folder

2) Within RStudio, go to the Session > Set Working Directory > Choose Directory. Navigate to the directory where the Melipona.csv file is stored.

3)Runthecommand

melipona<-read.csv("Melipona.csv", header=TRUE, sep=";")

This should finish reading your file without major problems.
