Diagnosis

Galaxiella toourtkoourt can be diagnosed from other congeners by following characters: caudal fin rays usually 13 (12-15); anal fin rays usually 8 (7-10); pectoral fin rays usually 12 (8-13); usually 36 (34-38) vertebrae; and 7 laterosensory pores in the preopercular-supramaxillary series. Adults very small (usually 2.06-3.06 cm SL in females; 1.67-2.40 cm SL in males); short caudal peduncle usually 19.6-21.9 % SL (17.2-23.8 % SL in females; 17.9-24.4 % SL in males); origin of dorsal fin more or less in line with anal fin (particularly females) with horizontal distance between dorsal fin and anal fin origins usually 0.0-2.7 % SL (2.5-2.8 in females; 2.6-3.9 in males). Adults possess three longitudinal black stripes (easier to discern in adult males) and reduced markings on ventral surface (typically two to three black blotches at isthmus) (Ref. 104902).
