  abstract = {{G}enetic variability of {T}richomycterus from the region of {T}orotoro ({B}olivia, {U}pper {A}mazon), distributed in the same watershed where the habitat is structured by waterfalls, canyons and a cave, was studied by allozyme (twelve putative loci) and {RFLP}-mt{DNA} ({DL}oop and cytochrome b) analyses. {A}lloenzymatic variation studied by {C}orrespondence {A}nalysis and {M}aximum {L}ikelihood {A}nalysis revealed a four-group structure, which was largely congruent with the distribution of the 14 mt{DNA} haplotypes. {T}wo of these four clusters ({I} and {II}) were differentiated by two diagnostic loci ({IDH} and {G}3{PDH}), two semi-diagnostic loci ({PGM} and 6{PGDH}) and consequently a very high {F}-st value (estimator theta = 0.77). {T}herefore, clusters {I} and {II} are reproductively isolated. {T}he distribution limit of these two (sibling) species does not correspond to those of the morphological species of {T}richomycterus identified in this region: the epigean {T}. cf. barbouri and the hypogean {T}. chaberti. {H}owever, hypogean fish exhibited two mt{DNA} haplotypes, a private one and another shared with the epigean {T}richomycterus from upstream reaches.},
