Relevant Information:

The members of the Dolichancistrus genus are very similar to Chaetostoma but with a completely ossified edge to the snout. They also have stouter bristles behind the gill cover and longer pectoral fins and a growth of fine odontodes around the edges of the mouth. Aquarium Care: Conditions the same as Chaetostoma where they will need a good water flow in the aquarium with a sand substrate and plenty of hiding places. Diet: Great algae eater, but you will have to subsidise this food with algae wafers and vegetable foods such as cucumber, zucchini and lettuce. Will also except tablet and worm foods. Remarks: To differentiate this genus, Dolichancistrus have hypertrophied (elongate) odontodes on the side of  the snout, small eyes and have 8 or more dorsal fin rays against 7 in the  other ancistrins. Also, Dolichancistrus will develop a single hypertrophied odontodes in the evertible cheek mass (rarely 2 or 3) vs. many, and males will develop really long pectoral- fin spines.
