This species was described in 2014, it is known from two populations inhabiting Ojo de Federico and Ojo de San Juan, two closely proximal springs in the lower Río Casas Grandes basin with water temperatures around 23 °C to 27°C.
The two localities dried out sometimes in the 1980s, which means that both populations of this species are lost leading to its extinction.

The Julimes Tryonia was discovered in 1991 and subsequently described in 2011.
The species was endemic to its type locality, a warm spring complex along the east side of the Río Conchos, where it formerly was very abundantly found in water with a temperature of about 44°C on hard substrate and in detritus which it apparently also fed upon.
The shells eached sizes of about 0,2 cm.
The only known habitat of the Julimes Tryonia was found excavated and draglined in 2001, no individual could be detected and the species is presumed extinct.

The Rio Grande Monkeyface is known, on the one hand, from subfossil remains from the Pecos River drainage in New Mexico, USA, but on the other hand also from live specimens from the Rio Grande in Texas, USA as well as from the Río Conchos in Chihuahua and from the Río Salado in Tamaulipas (both in Mexico).
The last living specimes of this species have been collected in the year 1898 near Bracketville in the Kinney County in Texas.
The Rio Grande Monkeyface is very possibly extinct, there exists, however, a vaguely possibility, that a population may still survive at least somewhere in Mexico.
The shells reached sizes of about 0,25 to 0,32 cm in heigth.
Hertlein’s Tryonia was restricted to a single locality near the terminus of the Río Casas Grandes drainage in Chihuahua, Mexico, close to the border to New Mexico, USA, which today is completely dry.
The species is now considered extinct.
