What's the correct name for this common fish (pics)

I've always seen them referred to as Peppermint Bristlenose. Online I found many people calling ancistrus hoplogenys but now looking at the forum I have seen pictures of a. hoplogenys that look nothing like these guys. So can someone tell me what is the actual name of this species, and does it have a L number? The Cat-eLog doesn't have "peppermint bristlenose" at all, and the "peppermint pleco" (L030) photos have no white tip to their tail and fin.
These photos are of a very young fish, the airstone in the picture is 55mm long.

I'm curious, I've seen dolichopterus without the white edging many times, and those with were the so called 'white seam' aka hoplogenys. Are they a synonym, or a variation in collection local?

My guess would be that the white seam on the caudal fin will disappear with age, just as with most bristlenose species.

A long perpetuated case of misidentificiation. The fish is A. dolichopterus as Silurus states.

They do more or less fade away on adults (at least to the fin ray tips).

Question still remains: what does the A. Hoplogenys look like... There isn't one in the cat-elog. Fishbase doesn't have a description, and the only picture is a stamp that looks pretty similar to L182. [But we all know how well stamps match the actual specie].

IIRC, A. hoplogenys is a brownish one. There was a DATZ article on this a while back, someone like Erwin would be well placed to elaborate...

Hi!
if I remember correctly Sonia Fish-Muller told me that Ancistrus hoplogenys has some orange spot on the body.
I shall ask here again to confirm this as this discussion was held a while back already...

Cheers
