Yep I'd agree entirely. I keep many Heterothele villosella and lots of Ceratogyrus spp., Pterinochilus spp, and other African species. The only one of them that I'd consider as instantly defensive is Pterinochilus murinus. The others seem no better nor worse than New Worlds.
It's the same with pokies. They seem to have picked up a reputation as fang wielding maniacs for some reason. Mine just tend to run away and hide when confronted.
If you leave them alone and don't aggravate them, then I find that most supposedly defensive spiders are fine.
Oh, and M. balfouri are very nice spiders in the flesh. Most pictures I've seen (barring Timo's one and a few others) don't do them justice.
I've never dealt with H. villosella or E. pachybus, but all the encounters I've had with P. lugardi and Ceratogyrus species were like less colorful OBT's, but the attitude of "if you get close enough I will bite you" was the same.
With the years I observed something about the Ceratogyrus spp., they are very unpredictable, can seem extremly calm and 1 second later they're extremly nervous and can be defensive ... i've been impressed by many Ceratogyrus spp with this ...
About the defensive behavior, the Pterinochilus murinus can be defenaive yes but my most defensive species is Hysterocrates spp., sold as gigas
Scientific name : Monocentropus balfouri Pocock, 1897
Location : Socotra Island
The adults of the species are kept and bred on dry substrate with a single live plant in the terrarium. The plant is watered a little once a month, and the adult females are provided with water dishes.
The spiderlings display communal behaviour and 10 spiderlings are raised together in 20 x 20 box for more than a year and they live happily with each other without any signs of predation or cannibalism. By doing this, they grow better, and it is interesting to see them communicating with each other when together like this.
We ca also kept some spiderlings with their mother in a terrarium for more that 1.5 years, (3cm legspan) without any problems whatsoever.
This is my experience.
I have article about this species, but only in Czech so i am trying translating this article into English.
That is all right I have no fear because balfil will be in the good hands, enjoy them. I hope we will meet at the autumn show in KWH, at this time I am trying incubate new eggsack which looks bad and nymph are crawl out from now...but we will se...
