Many but not all of the TEX and LL specimens from Mexico are available through REMIB, a specimen database run by the Mexican government. The above link and instructions there will take you to that database. These specimens were databased during the early 2000s and these on-line records have not been updated or corrected since. At least 20,000 Mexican specimens at TEX-LL are not included. A new, more complete, more up-to-date database of TEX-LL Mexican specimens will be available through the Lundell Portal in 2016.
