i like this one better, too.

add something about that the dhour can choose to respond to telepathy or any type of mental contact. (detect thoughts would only reveal what the dhour wants the caster to hear)
Alien Mind (Ex): Any attempt to establish a telepathic link to a dhour's mind (via detect thoughts, a psionic ability, dominate monster, and so on) automatically fails, unless the dhour chooses to respond.

is there a way to state this so that it is clear that both new dhours also have half HD as well? It takes 6 months apparently to grow back to adulthood.
Split (Ex): As a full-round action, a dhour can split into two identical dhours, each with half of the original's Hit Dice and current hit points (round down). A dhour with 10 hit points or less cannot be further split and dies if reduced to 0 hit points. A new dhour gains 1 HD per month, until it reaches maturity (7 HD).
Note that a split dhour will have a minimum of 1 HD, so it will take at most 6 months. Does this work?

It should probably be stated that a dhour can only have one mark at a time, and that the mark can be removed with psychic chirurgery. Also, I don't think that its target needs to be physically present at all at the time. I think we should also reintroduce some of these concepts as well:
How's this?
Psychic Mark (Ex): A dhour can target, or mark, an individual creature to better hunt that enemy. To do so, the dhour must focus on a foe who is present and visible, or on the depiction or description of one who is not, for 10 minutes. Any interruption ruins the attempt and forces the dhour to start the process again. Once this study is complete, that target is psionically marked.
The psychic mark can be detected with any ability that detects psionics, and can be removed with any effect that negates psionics (such as dispel psionics). However, a successful caster level check equal to the dhour's Hit Dice is necessary for the effect to succeed. A psionic chirurgery effect removes the mark and does not require a caster level check.
A dhour adds (half its Hit Dice?)as an insight bonus on all Gather Information, Listen, Search, Spot, and Survival checks made to determine the whereabouts of a psionically marked creature.
A dhour will not approach or attack a creature that has been marked by another dhour, unless the original dhour who marked the prey is dead.
