Diospyros embryopteris of the family Ebenaceae, the ebony family
Although this wood is sold by a handful of vendors in the USA, I have not found any information on its working properties. It apparently goes under the names of "pale moon ebony", "black and white ebony", and sometimes just "white ebony" (although there are other woods with that common name).
Some of the pics show a tan background, some show a greenish background. I don't know whether that's an artifact of the photography or because there is actually more than one species that is sold under this name.

planks from one vendor and turning stock from another, both using the name pale moon ebony
planks listed as pale moon ebony ... I doubtful about the bright orange color behind the black stripes ... I think the true color there is likely more like a nice rich tan.
two sets of turning stock, both from the same vendor, using the name black and white ebony ... I think the yellow background color is probably in reality more like a nice rich tan.
