I found a mob in Riwwi named "Animal Trainer KayzLc." Screenshot added to verify. Strangely, this mob is not part of the Riwwi hunter achievement. Have not seen it spawn after hunting here for a few days until I finally started killing the Yunjo, realizing they may also be PHs. After clearing the southeastern-most of the three buildings near the center of the zone many times, the first time I killed Kayin Wanjala this mob spawned. Kayin was not in the cell when I came back to clear it again, though this named that I hadn't seen before was. Everything else had respawned. It's possible Kayin Wanjala has a longer spawn timer, since he is a quest mob, but it's also possible that Kayzlc won't spawn with Kayin up. [EDIT: this was a coincidence, I have since seen Kayin and Animal Trainer Kayzlc up at the same time.] Lastly, it's possible that there is yet another rare named that I haven't seen in this zone before named "Animal Trainer Kayzic" (with an i), but it seems more like the title of this mob is an error.
Summons. Will also summon two "a vicious hynid" as a pet. After killing one, a few seconds later I saw the following as a new hynid spawned. "Animal Trainer Kayzlc whistles and a vicious hynid comes to their aid." Confirmed level 62.
[EDIT: After checking my achievements window, I had received credit for killing "Animal Handler Yluxx". I searched my logs and have no record of Animal Handler Yluxx. Old game, spaghetti code, etc. etc.]
