Someone I know inquired about an ID on this snake. Found on Isla de Ometepe in Nicaragua.

Without taking a look at any references, it looks like L. annulata to me.

Leptodeira annulatus. Notice how the stripe on the nape connects to the first dorsal blotch.

If it were México, I would call it a Leptodeira septentrionalis polysticta or something related. Not L. annulata... that being said, the two are confusing and I am not sure about C. A.

I apologize for being wrong. Definitely L. annulata.

According to this survey and another I read in Spanish, L. annulata and L. nigrofasciata are the only Leptodiera species to occur on the island.

Here is one of the reports:

Just because L. septentrionalis is not known from the island, we can't rule it out as the snakes identity. What if septentrionalis occur there but are thus far undetected?

That being said, I was thinking about the color pattern. I think Leptodeira septentrionalis tend to have a higher proportion of connected dorsal splotches than L. annulata.

I know not to trust everything 100% just because it's been published, but it's hard to go against a few reports where L. septentrionalis has not been found.

I've always thought L. septentrionalis had less dorsal "striping." My beliefs have been consistent with the several L. septentrionalis and L. annulata I've found. I also keep L. annulata and they have a lot of dorsal striping, which is why my initial guess was for L. septentrionalis.

Maybe the location the snake was found is wrong since it is through a friend of his?

In w. Mexico (can't speak for the whole country, as they look different in the south) the head and nuchal pattern would suggest Leptodeira splendida or Leptodeira "septentrionalis" polysticta... NOT L. annulata. However, last I checked, they decided that polysticta and septentrionalis were different species, and I believe reading that the C.A. septentrionalis were more similar to annulata than other septentrionalis... though I may be wrong on that.

Cheers,

Don Cascabel
