Ethnologue gives Bbadha as an alternate name of Lendu, but Blench (2000) lists Badha as a distinct language. A draft listing of Nilo-Saharan languages, available from his website and dated 2012, lists Lendu/Badha.
Besides the Balendru themselves, Lendu is spoken as a native language by a portion of the Hema, Alur, and Okebu.
Demolin (1995) posits that Lendu has voiceless implosives, /ɓ̥ ɗ̥ ɠ̊/ (/ƥ ƭ ƙ/). However, Goyvaerts (1988) had described these as creaky-voiced implosives /ɓ̰ ɗ̰ ɠ̰/, as in Hausa, contrasting with a series of modally voiced implosives /ɓ ɗ ɠ/ as in Kalabari, and Ladefoged judges that this seems to be a more accurate description.
