Hey Jeremy,
First: T. andersoni is definitely a valid species, and was once a subspecies of T. purpureomaculatus. As to whether or not it is the "Red phase", I haven't a clue. Assigning this particular serpent the common name of Anderson's PitViper doesn't described it too well (LOL).
In addition, I always get confused when it comes to the Genus Trimeresurus, because of all their color phases (Doah ?), so I can't help you with regard to this issue. Maybe someone who reads this can?
Second: Filthy posted quite recently at the (HS), and is supposedly going to be at Columbia. I posted a response, but no reply.
Third: I am calling for motel reservations today, and will be definitely at Columbia the entire weekend. I am taking two days to drive down, probably leave on the 11th of September. I will, (I hope providing I get a reservation), be staying the same place as Chris Harper, adjacent to the restaurant where the SHHS Banquet will be held.
Fourth: I am looking forward to seeing you again (!), (and meeting all those I have electronically communicated with for the past four years); this occasion should be a "BLAST" ! ! !
Fifth: I pray nothing happens to prevent either of us from from making the trip to Columbia, because I will have your loner book, (The Aggy Complex), in my possession at Columbia.
Very Best Regards,
Derek K.
P.S. Please let me know where and when we can meet at Columbia.
