Hemidactylus flaviviridis

Hemidactylus flaviviridis is a gecko known as the yellow-belly gecko or northern house gecko. Its range is given as Egypt, Saudi Arabia, the United Arab Emirates, Qatar, Oman, Iraq, Iran, Afghanistan, Bangladesh, Nepal, Pakistan, India, Socotra, northern Somalia, Sudan, Ethiopia and Eritrea, with a type locality at Massawa Island (Wikipedia, general species account).

That range list also names Argentina, which shows it has been introduced widely. The sources opened give nothing on size, colour, diet or breeding, so none of those is stated, and the entry is deliberately thin.
