Lowland (bara) is the darker one

Poecilotheria Subfusca C&P

These spiders have been subject to some controversy in recent years. Colouration and patterning in P. Subfusca can vary from specimen to specimen quite dramatically. Some dealers have been advertising and selling "highland" and "lowland" forms of P. Subfusca, with the "lowland" form usually demanding more money. However several reputable breeders have gone on record to say that they have observed both forms coming from the same sac. It has been theorised that the temperature the egg is incubated at determines the colouration. I hope to test this theory out myself over the coming year. As such, if you do buy a P. Subfusca, try not to pay over the odds for "lowland" specimens seeing as it is possibly just a P. Subfusca that has been incubated at a higher temperature. Ventral markings on both highland and lowland P. Subfusca are identical, and as such should be considered the same spider, even though dorsal markings can differ. Colouration seems to be based on regional distribution.



My LL in premolt (her abdomen actually got lighter while in premolt) black as night now

Poecilotheria subfusca"Highland" = Very dark Carapace with pointed star around the fovea. Whole folio on the abdomen, and are 15-16 cm in legspan.
As juveniles, they are very easy to see gender differences. Women have large white markings between the patella
and femur, males have only two small bright lines on the patella.

Poecilotheria subfusca "Lowland" = Light gray / brown Carapace with unclear star around the fovea. Distributed folio on the abdomen and is
18-20 cm in legspan. You cannot see the gender differences between P. sp. "Lowland", just by looking at the patella and femur.
The differences are best seen in mature individuals, many images on the Internet shows subadult individuals that do not show the
correct and clear differences between P. subfusca "Highland" and P. subfusca "Lowland".

Highland.
+1. The high elevation form is the dark one, and lives at 6,000+ near Nuwara Elyia. Adaptations to that elevation include a smaller size and more black on it, to absorb sunlight to warm up.

The 'lowland' form is actually mid-elevation near Kandy, and lives where temps are close to Florida, so they're much more heat tolerant. They have much more gold on the carapace and legs, and the folium isn't as dark.

Both occur in the high-rainfall mountains in the center of Sri Lanka, and appreciate more humid conditions than other Poec species (while still needing ample ventilation).

There's a lot of confusion as to their identity (in continential Europe, the name 'bara' is still commonly used). Both forms are commonly mislabeled in the trade, maybe more often than they're correctly labeled. No doubt the two forms are regularly mated together and mixed offspring distributed throughout the hobby.

So as a European, my best bet is to actually pick a rufilata or ornata instead, because who knows what I'd get as "bara" or "subfusca" ?

Actually, the spiders in Europe are probably labeled more accurately, as many of them have kept the 'bara' distinction. I think when the two were lumped together as a single species, the the problems in the US increased. It's confused many people here, and some of them assume that 'if they're both the same species, it doesn't matter if you pair up highland and lowland.' If they were still considered two separate species, Americans would have been more careful about knowing what they had and what they paired up.

I can tell you right away that a certain breeder (MS) sells the correct spiders. I got my "lowland" (I'm not going to use "bara" as it's a junior synonym not anymore in use) from him, raised him to MM, then gave him to a friend of mine in exchange for slings :)

Personally, I favorize the "lowland" - argueably more beautiful than P. metallica in my personal opinion :)

I favor the darker carapace form, aka highland (unless I get that messed up), guess it must be due to advan's black and gold monster :D

Yes, a lot of gold on the carapace, more prominent gold banding on the legs, and a light-colored folium.
