Diagnosis. Anablepsoides falconi is distinguished from all remaining species of the A. limoncochae species group by the color pattern in males, with body sides purplish-yellow, with five longitudinal rows of continuous red spots, the uppermost line formed by large red spots separated, the remaining lines with closely-set dots, forming lines, somewhat less continuous near the caudal peduncle, with only the first, third and fifth red lines extending to the caudal peduncle (vs. lines absent in A. hoetmeri, A. christinae, A. parlettei, A. rubrolineatus, A. limoncochae, and A. taeniatus, 5–6 red dot lines in A. chapare and A. luitalimae, seven orange-red interrupted dot lines in A. lineasoppilatae, seven small red dots forming lines in A. elongatus and A. bibosi, uppermost lines continuous and lowermost lines interrupted and formed by red dots in A. urubuiensis), presence of small filaments in unpaired fins (vs. without filaments), snout short, rounded, and upturned (vs. snout blunt), longitudinal lines with two parallel lines each with 5–6 minute contact organs in the ventral area starting at the pelvic fin base to vertical through the middle of the anal fin (vs. two longitudinal rows of 18–20 contact organs in A. hoetmeri, one longitudinal line with 6 minute contact organs, beginning at the level of the trunk reached by tip of the pectoral fin and ending at the level of the anal fin in A. luitalimae, three longitudinal lines with 10, 8 and 5 minute contact organs, beginning posterior to tip of pectoral fin and ending at level of middle portion of anal fin in A. chapare, 1–3 contact organ on free margin of each scale of antero-ventral portion of flank in A. urubuiensis), in males. Additionally, the new species can be distinguished from congeners by a lower number of pectoral rays (11 vs. 12–15), and a lower number of transverse scales rows (8 vs. 9–12, except A. urubuiensis).

Etymology. The specific names honors the musician, photographer, and environmentalist Francisco Falcon.
