This red-eyed pit viper from the Trimeresurus albolabris complex might be a yet undescribed species from the albolabris-complex. The clearest difference between the other Trimeresurus albolabris species found in Thailand is the deep red eye coloration, and the deeper red coloration on the tail.

These individuals were found around 200m asl elevation in July 2016. The habitat appeared lush in this wet month, but is likely quite dry in the dry season. The forest type consisted of bamboo, and mixed dry evergreen forest. Location in Thailand undisclosed. At higher elevation in the same forest area, we commonly encountered the Trimeresurus popeiorum, Pope’s Pit Viper. ON our one and only trip, we have encountered 3 females of the Red-eyed White-lipped Pit Viper, two of them seen in the pictures in this post, a subadult female, and a large adult female. Sadly we did not find any males. We will return to look for the males of this species.

      Dear Yannick,

      Currently, I have no further data as I have not had the time to return to the location. Because my friend has found this species on a trip before I went there, I feel that it is not my task to spread more info on location before the local herpetologists have looked into this.
      Sadly, they seem to be very busy with the many new discoveries in Thailand.
