Don't take this the wrong way...
I don't mean to bust your bubble...
But I honestly don't think you're ready for Lepanthopsis astrophora 'Stalky'.
Why?
You're asking for a book as a quick fix to gather up as much information about the plants you ordered before 8 weeks are up. Which implies you've never grown any of the plants you've listed before, ever. Your response to Bolero's post is a give away too.
It honestly took me several tries to grow Lepanthes properly. And I believe that if you can properly grow Lepanthes, you can grow Lepanthopsis, which is a wee bit easier to grow than Lepanthes.
The other species you listed you can wing. The Lepanthopsis astrophora will not be so forgiving (as in they can start rapidly dropping leaves and die within a week or two if conditions are not correct). Especially if you're trying to use pot culture for it.
They like it evenly moist without being soggy. And they like moderate to high humidity (70% and up). If your humidity is low, you will not be able to grow this plant.
Nothing below 60% humidity is tolerated in the least bit. 60% is pretty much the breaking point for Lepanthes and Lepanthopsis.
It grows in shade in cool to intermediate temperatures (55 F - 85 F/13 C - 29 C).
They've got thin roots that can break very easily during repotting (if you're using pot culture).
I recommend mounted culture, (pm me for more specific info, if you're interested).
This plant pretty much is grown the same way as their close cousins, the Lepanthes.
I'm not trying to scare you, but this is the honest truth.
If you choose to go ahead and try your hand with Lepanthopsis astrophora 'Stalky', by all means, you're free to try.
Oh...and as far as I know, there aren't any specialist books that go into detailed growing instructions on how to cultivate Lepanthes and Lepanthopsis. I could be wrong...
