To my knowledge the Lotus does not alert you when they are in the mission. They begin spawning after wave 15 on Venus def, which is terrible. These enemies take extremely reduced dmg in the front which forces you to somehow get to their back. The original bursa units loved to try and charge you and would be easy to hit in the back because after charging you it would take them a bit to turn around. These however will normally plant themselves in the ground and begin firing heat seeking missle barrages, nully stick grenades or energy leech spheres (depending on the bursa). The worst of those being the missle barrage since each one does as much as a Grineer Bombard of the equivilent level.

So, in essence, enjoy the game while you can because once you get these the Corpus become more powerful by an extreme amount. The corpus already had nullifiers which made them the strongest faction, by far, and now they have bursa units which are the strongest enemies in the game atm.
