So we have two different Rhinoceros beetle subspecies.
Trypoxylus dichotomus tsunobosonu (TDT) and Trypoxylus dichotomus politus (TDP)
But what's the difference between the two?
Well for starters TDT is native to Taiwan, while TDP is native to Thailand.

I've also noticed these main differences when comparing the two.

Aside from the difference in color, the two of them have a different upper horn thickness. TDT has a skinny horn, and TDP has a thicker horn. More akin to the Japanese subspecies.

I also noticed on the ends of the lower horn. TDT has sharper points and a different dip shape. (See the last two photos)

These were just the difference I noticed most prominently. I'm sure there are more, but I hope you found this educational and fun!

Dorcus Schenklingi
This individual is 70mm+
Not our largest one, but he has very attractive proportions. Very nice long slender mandibles, with nice curves.
