Arright, got a few problems with this:
1.First off, I don't think you have any Lorcar DNA to compare this to. A DNA sequencer is well and good, er, I guess, but its not like its some kind magic Lorcar making machine...
2.Tying in with the above, I doubt there would be much public information on the Lorcar. Well, there WOULD, but nothing on their DNA or any other classified stuff like that.
3.You'd need to be more specific about psychic power. Lorcar are VERY varied in psychic ability, and hell, some don't have any at all.
4.Lorcar ARE sentient. They attack other empires in part because they think differently from us and in part because they believe all other races are threats to their continued survival. They also figure that they shouldn't waste a potential meal, which is why they devour their foes.
5.If they're Lorcar, of a sort, and look similar to Lorcar. . .They wouldn't look even vaguely reptilian. Lorcar are insects.
