Genotypes at five intron loci showed four reproductively isolated clusters of individuals. The CO! sequences showed four major mitochondrial lineages, each diagnostic of a cluster as defined by nuclear markers. No mitochondrial introgression was detected. The average Kimura-2 parameter nucleotide distance separating clades was 0.061-0.120 (net: 0.055-0.114), while the distance separating individuals within a clade was 0.002-0.008. Additional, partial cytochrome-b gene sequences were used to link these samples with previously published sequences of reference specimens of the three nominal species. One of the clusters was identified as H. undulata and another one, as H. uarnak, while two cryptic species were uncovered within the recently-described H. leoparda, challenging the current morphology-based taxonomy of species within the H. uarnak species complex. specialized Intron-size polymorphism Cytochrome oxidase I Cytochrome b Himantura leoparda Cryptic species Taxonomy ZANZIBAR TAIWAN INDONESIE 034 66 1 429-435 2013 1055-7903 https://www.documentation.ird.fr/hor/fdi:010058219 10.1016/j.ympev.2012.09.023 1055-7903 [F B010058219] https://www.documentation.ird.fr/hor/fdi:010058219 https://www.documentation.ird.fr/intranet/publi/2013/01/010058219.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-02-06 2017-08-23 fdi:010058219 fre
