Figure 3 in Do mismatched genitalia promote mechanical isolation in syntopic species of Phalloceros fishes (Poeciliidae)?

Figure 3. Among-individual variation in the presence/absence of dark lateral spots and the morphology of adult female papillae in Phalloceros anisophallos and Phalloceros leptokeras from the Parati-Mirim River in relationship to molecular barcode information. The barcode sequences for each specimen are listed at the bottom and correspond to mitochondrial (COI) and nuclear (MG1) DNA haplotypes. Based on the orientation of genital papillae, these specimens were initially identified as follows: P. anisophallos = MNTI 14559, 14553 and 10679; and P. leptokeras = MNTI 10684 and 10680. Note that morphologically and molecularly based species identifications for individual MNTI 14559 conflicted with each other, probably owing to an apparently aberrant papilla (see main text for more discussion). The size of the specimens corresponds to the standard length (SL), measured with digital callipers from the tip of the snout to the posterior margin of the hypural plate.
