Atopochilus cf. pachychilus ?

[Stan]

I got this little cutie together with some Chiloglanis sp. It must be about 5-6cm long, it does not really like bloodworms, frozen Artemia or Tabs I give to the other african suckers and it keeps the front glass clean. Never seen it attacking Chiloglanis or the other way around.

Isn't this some kind of

Euchilichthys

?

Looks like it to me

I have some problems distinguishing the both genus Atopochilus and Euchilichtys. Are there some clear superficial differences between them? The fish was identified by the seller, so no 100% warranty.

They are quite similar. This is from Friel:

Mandibular teeth spatulate and unicuspid; large posterior pectoral-spine serrae; one or only a few pores at sites along the cephalic sensory canals; fewer than 40 vertebrae: Atopochilus

Mandibular teeth with lengthwise keel creating trowel shape and sometimes bicuspid from wear; small posterior pectoral-spine serrae; several pores at various sites along the cephalic sensory canals; more than 40 vertebra: Euchilichthys

So the easiest way may be the relative size of the spines on the posterior edge of the pectoral fins, and the shape of the teeth. Difficult for me to tell on your photos but I would lean towards Euchilichthys.
