Kris to, Dear 2012 Journal San Francisco Jimbal, Mpio. Jila, Chiapas, Mexico June 14 Jorge, Diana, and I set out at 09:50 and searched in several patches of red bananas in the village. I found 3 Bolitoglossa that look like B. rufescens but could also potentially be B. hartwegi, given that they have white mottling under the tail and the feet look slightly different from B. rufescens; on the other hand, I've never found B. hartwegi in bananas before. We took a trail to the out of the village and quickly got into nice, if somewhat disturbed, primary forest. The area is very rocky (karstic) with tons of holes/small caves, and the broadleaf trees growing here are not huge, perhaps because of this. There is a rather thick understory as well - habitat looks almost exactly like we saw in May 2011 in Retalhuleu, Alta Verapaz, Guatemala. I got what I think is a B. hartwegi (darker coloration, larger size) under a small log immediately after we started searching at 09:50. Shortly after, Diana found a Bolitoglossa in some leaf litter between rocks along the trail along with what might be a salamander egg (collected). I then got 1 Bradypodion + 1 B. hartwegi in area where wood had been cut, up wood chips and between two pieces of bark, respectively; I then focused on leaf litter and found 6 more Bolitoglossa in areas of thicker leaf litter on slopes along the trail. Everything was very wet ifc of yesterday's rain. Those salamanders have some brown speckling on the dorsum that I don't remember from B. siles but otherwise look just like it on cursory examination, although I haven't seen B. siles in a while. Hard to imagine it here unless it is also distributed along the Sierra Norte de Chiapas between here and Guatemala. I guess it could be a different species as well. Heard tons of howler monkeys.
