Figure 3 from: Yessoufou K, Van Der Bank H, Herbert D, Greenfield R (2013) Revisiting species delimitation within the genus Oxystele using DNA barcoding approach. ZooKeys 365: 337-354. https://doi.org/10.3897/zookeys.365.5356
Figure 3 - Summary of both Bayesian and parsimonious trees. Values above branches indicate bootstrap supports; values under branches indicate posterior probability. All distinguished species are indicated at the tip of the tree. Branches without values indicate non-supported nodes; the small circle indicates a specimen of Oxystele impervia (HVDBM028-10) that was misidentified based on morphology; large circle indicates four specimens morphologically indistinguishable from Oxystele variegata (HVDBM070-10; DQ061092; HVDBM058-10; HVDBM059-10), but that are, based on both barcoding analysis of species delimitation (see Table 1) and phylogenetic tree analysis identified as Oxystele impervia (see also Appendices 1 and 2).
Figure 2 from: Yessoufou K, Van Der Bank H, Herbert D, Greenfield R (2013) Revisiting species delimitation within the genus Oxystele using DNA barcoding approach. ZooKeys 365: 337-354. https://doi.org/10.3897/zookeys.365.5356
Figure 2 - Determination of the threshold genetic distance for species identification. The density plot indicates transition between intra- and interspecific distances; the genetic distance corresponding to this transition (dip in the density graph, here approximately 0.05) indicates the suitable threshold to the dataset. This method does not require prior knowledge of species identity to get an indication of potential threshold values.

Figure 1 - Evaluation of barcode gap in the dataset. A Boxplot of the interspecific (inter) and intraspecific genetic (intra) distances, indicating the existence of a barcode gap i.e. intraspecific distance is longer than intraspecific distance. The bottom and top of the boxes show the first and third quartiles respectively, the median is indicated by the horizontal line, the range of the data by the vertical dashed line and outliers (points outside 1.5 times the interquartile range) by Bold vertical lines B Lineplot of the barcode gap for the 56 Oxsystele specimens. For each specimen in the dataset, the grey lines indicate where the smallest interspecific distance (top of line value) is longer than the longest intraspecific distance (bottom of line value), therefore indicating existence of barcode gap; the red lines show where this pattern is reversed, and the closest non-conspecific is closer to the query than its nearest conspecific, i.e., the situation where there is no barcoding gap.

Figure 1 - Maximum likelihood tree resulting from the analysis of the combined dataset. Support of major nodes is provided by BV (only BV ≥ 50% are figured). For the group of interest we used coloured frames to highlight the seven sampled morphospecies (Uloma caledonica, Uloma clamensae, Uloma condaminei, Uloma isoceroides, Uloma jourdani, Uloma kergoati and Uloma opacipennis). On the right, corresponding male habitus are also included for illustrative purpose. Results of the PTP analysis are provided using coloured branches. Putative molecular species are indicated using transitions between blue-coloured branches to red-coloured branches. For the two cases (for Uloma isoceroides and Uloma jourdani) in which two distinct putative species clusters are inferred we added numbers into brackets to indicate the assignation of specimens to a specific species cluster.
