Lujan, NK., JW Armbruster & MH Sabaj, 2007. Two new species of Pseudancistrus from southern Venezuela. Ichthyological Exploration of Freshwaters 18: 163–174.

If anyone has a copy of this i'd be appreciative, i can't find it on any electronic journal sight, i think this journal is rarely put in this format. I believe the one is Pseudancistrus sp. 'upper_orinoco', is now Pseudancistrus pectegenitor. Anyway thats about it, if you got the info, post it or email me :D

Update:
The other is Pseudancistrus yekuana

Heres an abstract from the above cited paper:

Two new species of Pseudancistrus are described from the upper Río Orinoco and Río Negro in Southern Venezuela. Pseudancistrus pectegenitor was collected in the main channel of the Río Orinoco near the mouth of the Río Ventuari and in the middle reaches of the Río Casiquiare. It differs from congeners by having 10-11 dorsal-fin rays (vs. seven), adpressed cheek odontodes reaching to three or more plates beyond the opercle in adults (vs. maximally to rear edge of the opercle), plates of ventral row of caudal peduncle with dorsal laminae strongly concave, accentuating the medial keel of the ventral plate row (shared with P. sidereus), and large oral papillae internal to the dentary tooth cup (shared with P. coquenani, P. orinoco, and P. yekuana). Pseudancistrus yekuana is known only from the type locality, immediately upstream of Salto Tencua in the upper Río Ventuari. It differs from congeners by having large oral papillae internal to the dentary tooth cup (shared with P. coquenani, P. orinoco, and P. pectegenitor), lower lip reaching to middle of pectoral girdle (vs. to anterior edge of pectoral girdle), pectoral-fin spine maximally reaching posterior base of the pelvic-fin spine when adpressed ventral to the pelvic fin (vs. at least halfway through pelvic-fin insertion) and by several morphometric differences.
