Previous distribution.

Botosaneanu and Iliffe 1999, 2002, 2006; Álvarez and Iliffe 2008.

Type locality is Cenote Pabakal (Papakal), Yucatan. It was also found in cenotes Kankirixche, Kakuel, Chuih-Hol Dos, Xacha, and San Geronimo (all in Yucatan).

Remarks.

Individuals of Y. robustispina were collected in a third of all localities visited, where it occurred in freshwater between 3 and 49 m in depth. In eight cenotes Y. robustispina co-occurred with the isopod C. anops . Agreeing with our observations, previous records referred specimens caught in freshwater between 5-50 m in depth ( Botosaneanu and Iliffe 1999, 2002, 2006). Known localities of this species have been doubled.
