Remarks Mature males possess a slightly curved bony hooks on the pelvic- and anal-fin rays. Pelvic fin consists of one hook per segment, which are arranged on the distal portion of the first to fifth (rarely on the sixth) branched rays. The distal portions of the last unbranched anal-fin ray and up to the eighth or ninth (sometimes tenth) branched anal-fin rays have one or two pairs of hooks per segment.

Diagnosis

Boehlkea weitzmanican be distinguished from B. fredcochui by the following characters: complete lateral line (vs. incomplete); four rows of scales below lateral line (vs. three); a conspicuous vertically elongated humeral spot present (vs. a humeral spot absent); and 17-21 branched anal-fin rays (vs. 22-25). It can be diagnosed from B. orcesiby having 13-14 maxillary teeth (vs. 5-12), head length 27.9-29.9% (vs. 24.3-27.5% of SL), and color pattern consisting of black chromatophores in the basal half of dorsal fin, distal portion of pelvic fin, lower caudal-fin lobe and anal fin (vs. unpigmented fins) (Ref. 118101).
