Fig. 3 in Taxonomic reassessment of the Herpetoreas xenura (Wall, 1907) (Squamata: Serpentes: Natricidae) from Myanmar with description of a new species
Fig. 3. Species delimitation by ASAP using Cytb gene sequence of the genera Amphiesma Duméril, Bibron & Duméril, 1854, Amphiesmoides Malnate, 1961, Hebius Thompson, 1913, Herpetoreas Günther, 1860, and Sahyadriophis Patel, Thackeray, Campbell & Mirza, 2023. The columns represent the different species group partitions, and the colours depict species hypothesis in each partition. The values above the column represent the number of inferred species in the partition (upper value) and the ASAP-score (lower value). The ASAP-score of the best partition selected is indicated in red. The Neighbour-joining cladogram (right) supports the species delimitation on the bar charts (left). The colour dots correspond to the probability of the nodes, darker colour depicts lower probability, and uncalculated probability is shown in grey dot.
