Riley's 13-year Cicada - Magicicada tredecim (female, body length 29 mm)
Location: Durham NC (USA)
I picked up a freshly-emerged pair for detailed photos. Female has no visible sound-producing organs at the base of the abdomen. In cicadas, sound-sensing organs are in the legs, apparently--see:
Alt and Harlan. Sensing of Substrate Vibrations in the Adult Cicada Okanagana rimosa (Hemiptera: Cicadidae). J Insect Sci. 2018 May 1;18(3):16. doi: 10.1093/jisesa/iey029.

I see reports that females of some cicada species do have tymbals, but I would like to see confirmation of that in the scientific literature. Reading popular accounts, it seems there is some confusion about tymbals being used for sensing sounds. I think that is incorrect, and they are the sound producing organs only. There are smaller organs for sensing sounds.
Edit. These cicadas are alive--I chilled them briefly in my refrigerator so I could get detailed images of the underside, which is otherwise difficult. I released them after they warmed up.

Riley's 13-year Cicada - Magicicada tredecim (male, body length 26 mm)
Location: Durham NC (USA)
I picked up a freshly-emerged pair for detailed photos. Male is slightly smaller than female, and the singing organs (tymbals) are visible at the base of the abdomen. Each tymbal is covered by a flap called an operculum.
