Fidicina torresi (or F. Mannifera)
Not sure if it is a Fidicina torresi or a Fidicina mannifera (EXPLAIN: THESE TWO CICADA SPECIES ARE NEAR IDENTICAL!) adult male who captured nearby my house. Don't get worried, I let it flee right after the photos).
The doubt about the species is justified because i searched both names from two different sources and the related cicadas were roughly equal (but I think it is most likely to be a Fidicina torresi because of the site Faunaparaguay.com, where i found the cicada's song audio file, which is exactly like the captured cicada's song, sounding like a zizizizizi).
The specimen above was about 4 cm long, head greenish with dark green eyes, back and legs and abdomen dark brown and cream colored belly. High level of hairiness in the body.
