It looks like a Gonodactylaceus falcatus to me, but I am confused by the meral spot coloration. What do you think?

It's not G. falcatus, because G. f. has yellow-green meral spots.

I think it's a Gonodactylaceus glabrous male.
Take a look at Roy's list here
There you can find more infos about this and other species.
 
That makes sense, Timmy. It appears that there is no median carinule (as far as I can tell ) on the 6th abdominal segment.

I have a few, smaller Gonodactyloid species. This one, however, seems very aggressive. It attacks everything that comes near it!
 
I can't see the sixth abdominal segment well enough to tell if it is G. graphurus or G. glabrous. It is definitely one of the two. It is not G. falcatus (yellowish green meral spot) or G. ternatensis (red intersegmental lines). The blue antennal scales are diagnostic for male G. t, but not necessarily for G. glabrous and G. graphurus which are more color polymorphic.

If I had to guess, I would bet on G. glabrous from Indonesia.

This is a tough, coastal species that can handle relatively poor water quality with temperature and salinity swings (although it is of course best if you can avoid this). The inherent instability of small tanks argue against keeping sensitive species such as Odontodactylus havanensis in them, but species such as G. graphurus, G. glabrous, G. viridis, and G. chiragra can do reasonably well in these conditions. The biggest rist is not to over feed and make sure you remove excess food after a few hours.

G. glabrous is a fairly robust species with a powerful strike for its size. That suggests that a glass tank might be at some risk if you have a large individual (> 65-70 mm). I've never had one break a small glass tank, but I have had them break out of plastic holding cages and containers. Usually there are problems only if the animal tries to dig and hits a corner or bottome edge. If you are worried about this (I'm not because my lab has floor drains), you might lay down thin plexiglass strips to protect the bottom edges of the tank.

Mt G. glabrous (Typhon,R.I.P. after a bad molt) was an amazingly active and interactive Mantis. She was really closing in on mt tern for fave mantis (My platysoma still ranks up there, as do my peacocks).
Lucky find, in my opinion, and Dr. Roy isn't kidding when he says that they are powerful hitters for their size. Mine would take out crabs bigger than she was.
