Etymology: Apistogramma: Greek, apisto = uncertain + Greek, gramma = graphic signal (Ref. 45335); barlowi: Named for George W. Barlow, for his substantial contribution on cichlid fish biology.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 4.8 - ?. Tropical; 29°C - ?
South America: known only from around the Tierra típica northwest of Pebas, Peru.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.4 cm SL male/unsexed; (Ref. 75695)
(total): 14 - 16;
soft rays: 5 - 8. Distinguished from all congeners by the combination of the following characters: over-proportionally large head and mouth with massive jaws and hypertrophic lips in adult males, 3 infraorbital pores; a lyrate caudal fin in adult males with immaculate lemon-yellow lower lobe and vertical rows of spots in its upper bluish hyaline lobe, truncate and immaculate in females; extended first membranes of the dorsal fin, a distinct breast band in basal part of vertical bar 2 and posterior lateral spot in female; and absence of caudal peduncle spot (Ref. 75695).
Appears to be restricted to forest streams, with a preference for fast-flowing, cooler, and crystal-clear, acid to neutral water (Ref. 75695). A reddish morph of this species was collected in a small clearwater igarapé, about 1 meter wide and approximately 30 cm deep, with fine white sandy bottom, no submerged vegetation, rocks or pebbles, a pH of 4.8 at a temperature close to 29°C (Ref. 75695).
