Chilobrachys bicolor

[RED-LEG]

I bought this girl as Chilobrachys bicolor but cannot find any info on that species. Is this the correct name?

 

[Scourge]

Unlikely I'm afraid:

Don't loose faith just yet, if you have a juvie it might still grow some color. I had an female C. Brevipes that looked like that, all sandcolored. But when she turned adult she got just the right colors.

 

[RED-LEG]

Thanks for the replies. So do you think its huahini or andersoni? Any pics of them? She has been much more orange coloured untill her last moult when she took on this more sandy colouration.

Is it common for other Chilobrachys to be sold as bicolor? Is bicolor a sought-after species?

One more question....
Are Chilobrachys normally rather small? She has grown quite fast but appears to have stopped growing now.

Thanks again.

Lee.

Bicolor, dyscolus and brevipes are all unusual T's in the hobby. Often mixed up too. But they are not rare. They get medium sized, leggy so to speak. My brevipes was at least 16-17cm when I sold her. Bicolor is said to be around 13 cm legspann, so they are a bit smaller.

Well - in the hobby there are basically three species offered regularly (but under a wide array of names ...):

C. dyscolus (as C. burmensis, C. brevipes, C. sericeus, C. soricinus a.o.)
C. sp. "Guangxi" (as C. andersoni, C. huahini, C. bicolor a.o.)
C. fimbriatus

To my knowledge none of the aliases are available in the hobby, mainly because all are originating from Burma, and Burma is not easy to collect or export from. At least I haven't seen or examined any species labelled as any of above aliases that were identical to the alias species. All have been either C. dyscolus or C. sp. "Guangxi"

To put it to the point:

C. dyscolus females
Uniformly dark brown, ash grey to black:
Leg I longer than leg IV
Front legs with fuzzy setation
Scopula on tarsus IV usually undivided
Males tolerably uniformly grey:

As opposed to the characters found in the large tan Chilobrachys species from Thailand and the far east. For instance C. sp. "Guangxi":

Females
Beige, brown orange, greyish tan to cocoa colored:
Leg IV longer than leg I
Front legs without fuzzy setation
Scopula on tarsus IV usually divided
Males bicoloured, generally beige with darker tarsi and metatarsi:

C. fimbriatus is so characteristic that a description is not needed for hobby use.

In recent years new Chilobrachys species has been introduced to the hobby:

Chilobrachys nitelinus Recognized by small size and the hairless orange chelicerae
Chilobrachys sp. "Penang" Recognized by the curly hairs, large size and stockyness
Chilobrachys cf. fumosus Recognized by the small size and short spinnerets
Chilobrachys sp. "Meghalaya small" Recognized by the small size and being black with red hairs postmolt ;-)

All of which are the result of our collecting teams hard efforts ;-)

I hope this was of some help with the numerous fake Chilobrachys names occuring in the hobby.

And - look forward to our breedings of Chilobrachys stridulans a favorite species of mine that we also hope to introduce soon ;-)

Thanks for the info. Hopefully i can use this to positively ID some of my own Chilo's.

 

[RottweilExpress]

Ok, thanks Sören. That's kind of disheartening to read.

Thankyou very much for your time. I am still none the wiser as to which I have though! I will use your info, and go and give my specimen a good inspection.

 

[B-fish]

here is somethign i found on the internet http://www.spidy.goliathus.com/english/chilobrachys-bicolor-id116.html. From Chilobrachys bicolor body structure looks like a male sorry

 

[phormingochilus]

The spider Ondrej has on his website is Chilobrachys sp. "Guangxi" not C. bicolor. C. bicolor has very distinct coloration: Black femurs dorsally and bright ochre yellow ventrally...

Depending on age and size RED-LEGs spider is C. sp: "Guangxi" in my opinion. But the appearance can cheat on you as both C. dyscolus and C. sp. "Guangxi are identical as young juveniles. C. dyscolus changes color to black, dusky brown over a few instar when the female reach maturity. Also the character of the divided/undivided tarsus IV is only useful in mature (full sized) females.

Thanks for that link. She did look just like the female in that pic untill her last moult when she lost the orange colouration.

She is definately a female as I have positively sexed her from a moulted skin.

 

[RottweilExpress]

Ok, I dug out a pic of my C. Brevipes before I sold her. She was not as large as I thought previously, I found the mail I sent to the buyer about her last molt being measured to exactly 12 cm (around 5").

She was very similar to your spider when she was a juvie, Red leg. At the pic here, she's sitting on my back. My gf took the pic and it's probably the best I got.

So phormingochilus, this is a C. Dyscolus according to you then? It sure does fit the description.

 

[phormingochilus]

Yes this definitely fits the description and I would say that this is a C. dyscolus to the best of my knowledge (as all hobby "C. bicolor" so far) ;-)
