First..... The pic above is a conversion (built by Mr. Pink at Modern Synthesist), and not a GW model. However, rumors have it we are looking at one of these things being tested out. Its crazy big, but so is the new Tau Riptide. Is this for an apocalypse expansion? or for a tyranid codex? To be honest I have no idea, but my guess would that it is still for a codex release.
Please remember that these are early playtest rumors, salt is always required.

Tyranid Dominatrix
It looks like a tyrant, but with more legs.... does not look like the old epic model.

*Once per turn the dominatrix can double the synapse range of one other synapse creature on the battle field, including itself...this affects the Shadow in the Warp range as well.
*All Tyranids within 6" gain Feel No Pain just like Catalyst, it is gained at the start of the turn and lasts until the next Tyranid turn, but as an effect. So those units may move outside the field and retain it.

What is a Tyranid Dominatrix?
I had no clue what one was, and as usual when I see a new model type, its time to do a little quick research to see if the model has a precedence. So here is a good decription of what a Tyranid Dominatrix is.
via Warhammer 40k wiki
A Dominatrix (Tyranicus praepotens) is the Tyranid Norn-Queen's link to the Tyranid swarms on the ground as the Norn-Queen must stay aboard the Hive Fleet's largest Hive Ship to continue birthing more Tyranid bioforms. This colossal creature is a fearsome opponent, for its sheer mass and panoply of bio-weaponry dwarf that of an Imperial super-heavy tank. The Dominatrix is no unthinking beast -- its level of intelligence is akin to that of the Hive Tyrant, and its link to the Hive Mind surpasses even those mighty creatures. Whilst within range of the Dominatrix's psychic aura, lesser Tyranid creatures become little more than an extension of the Dominatrix's will. As a result, a swarm under the Dominatrix's direct supervision functions with uncanny efficiency and a tactical genius that is beyond compare. Fortunately, such beasts are extremely rare in all but the most advanced and mature Tyranid swarms, for where the Dominatrix treads, doom surely follows.
