    Lost in the Amazon: Rediscovery of the Rio Santa Rosa Mushroomtongue Salamander (Caudata: Plethondontidae) from Ayacucho, Peru | Zootaxa

    Abstract

    Bolitoglossa digitigrada Wake, Brame and Thomas, 1982 was described from a few kilometers upstream from the Rio Santa Rosa, Ayacucho Region, Peru, at 1000 m a.s.l. in the Eastern Amazonian Montane Forest. Besides the type specimens, no additional collections or sightings of B. digitigrada had been reported for 43 years, and there is no information about its phylogenetic position inside its group. During a field expedition conducted in October 2022, we found four individuals of B. digitigrada in a corn and banana field near the community of San Jose, approximately 2.7 km from the type locality. Here, we provide information about living specimens, update description of coloration in life, elevation, and evaluate the phylogenetic relationships of B. digitigrada with a molecular phylogeny based on a 16S rRNA sequence.

    Myobatrachus gouldii (Turtle Frog)

    Grumpy, dumpy, and gorgeous! I'm so lucky to have these nearby. They spend most of their lives underground but when it rains in October-November you can hear them call as they start to emerge.

    Western Banjo Frog (Limnodynastes dorsalis)

    They get their name because their call sounds like a banjo! A commonly heard, but not often seen frog native to Southwest Australia. They spend a lot of their lives burrowed underground or under leaf litter.

    (Scottsdale, AZ) Gila Monster or Chuckwalla?

    Currently in an argument- "too thin to be a Gila" vs "too beaded to be a chuckwalla"

    Very sluggish, but it's only like 19c today. Maybe 25-30cm long

    The common milk frog (Trachycephalus typhonius)

    This is a Trachycephalus typhonius, formerly Trachycephalus venulosus, from Yucatan.

    These frogs secrete a sticky and irritant milk-like fliud through its skin when bothered. Several years ago I got some some of that fluid into my eyes by accident - that hurts similar to scratching one's eye after touching a spicy pepper. So, they are not terribly toxic but I certainly do not recommend the experience.

    Funnily enough I just ran a search and found a publication of someone who describes a similar but worse experience: https://www.thebhs.org/publications/the-herpetological-bulletin/issue-number-152-summer-2020-1/3101-09-a-caution-on-handling-i-trachycephalus-venulosus-i-anura-hylidae-toxic-effects-of-skin-secretion-on-human-eyes/file

    You may notice that the finger pads of this frog look green. That's because its bones are green! A characteristic feature of this species. Here is a photo (not mine) of a skeleton of one of these : https://www.pybio.org/wp-content/uploads/2008/06/t-ve

    Alvarado’s Webfooted Salamander, Bolitoglossa alvaradoi: Activity, hunting behavior, and prey selection in Costa Rica

    A new paper on a Bolitoglossid showed up in my alerts today! 🥳

    It is a one-pager and comes with a beautiful photo of a foraging arboreal salamander 😄

    Imantodes cenchoa

    Found this Imantodes cenchoa sleeping on top of a leaf in Punta Laguna, Quintana Roo.

    Here is a photo of where it was sleeping:

    There are a few different snakes of the genus Imantodes in Yucatán. What sets this species apart is that the row of scales on its back consists of enlarged scales. Here is a closeup emphasizing that row of scales. The green arrow points at an enlarged mid-dorsal scale, the blue arrow at a regular scale.

    In comparison, here is a photo from an Imantodes tenuissimus that I took back in 2009 in Mérida, Yucatán (with a less sharp camera), and a closeup of its mid-dorsal scales that does not show this enlargement.

    Yucatan casquehead tree frog

    One of my favorite frogs! Spent some time specifically looking for it. Managed to find two near Cobá, in Quintana Roo (in the Yucatán peninsula). This frog hides in holes in lime stone and tree trunks, and makes use of its flat head to block the entrance. This type of defense is known as phragmosis.

    Some other shots:

    Anole sleeping

    Found this anole in Yucatan. I am not sure of its exact species - probably an Anolis sp..

    Anoles often sleep at the tips of leaves and twigs. My guess is that this is a strategy to prevent nocturnal predators sneaking up on them through the branches without making its bed vibrate. When woken up they can quickly drop down.

    Possibly Eleutherodactylus planirostris

    Found many of these frogs under a wet trash bag in a back yard in Mérida, Yucatán. I made use of a handheld flash with a remote trigger for lighting, and a Sigma 105 mm as my macro lens.

    These frogs do not seem to match with any of the local frogs reported in Julian C. Lee's field guide to the amphibians and reptiles of the maya world.

    From a reverse image search, I mostly found images of the green house frog Eleutherodactylus planirostris. Eleutherodactylus planirostris is native to Cuba and the Bahamas, and is often introduced with plants that come from green houses in those areas. These frogs go from tadpole to frog while still inside of the egg, which explains why the

    Unknown frog in the desert (Payne's Find, Western Australia)

    Several 2cm long frogs were found in this tiny little granite pool in the desert. Any IDs would be welcome, I suspect it could be a Litoria of some sort.

    Golden Flying Snake

    I think that is what it is. Extraordinary climbers. I find them on the second floor of the house every few months. I see them outside a few times a week. Colouration is highly variable locally. Here they are green and black.

    Wikipedia and a few other sources say this

    Also, it is reported to take snakes occasionally, and to avoid frogs, though frogs are also reported being eaten.

    In Cambodia they always take frogs, and will strike poisonous toads, then spit them out.
