Fig. 1 in Understanding the color variability and resolving taxonomic confusion in the sea cucumber Isostichopus badionotus (Echinodermata, Holothuroidea): a revision of the genus Isostichopus

Fig. 1 (continued on next page). Color patterns of species and subspecies of Isostichopus Deichmann, 1958. A–J. Isostichopus badionotus (Selenka, 1867). A. Pink background and dark brown spots (Chips pattern – CH) (BT99, Panamá). B. Close-up of A, note large dark brown spots and small dots. C. Light brown background and darker ocellar spots (CH pattern) (INV TEJ1125-Ma10, Colombia). D. Close-up of C, note large ocellar spots and small black dots. E. Uniform black background (Uniform pattern – U) (BT59, Panamá). F. Beige background color with a reticulum of darker brown and yellow papillae (Reticulated pattern – R) (USNM 1659460-BT20, Panamá). G. Close-up of F, reticulated pattern in detail. H. Reticulated pattern with brown papillae (R pattern) (INV TEJ1167-SM4R, Colombia). I. Close-up of H, reticulated pattern in detail. J. Black background and yellow papillae (Black and yellow pattern-BY) (INV TEJ1176-SM13, Colombia). K–Y. Isostichopus maculatus phoenius (Clark, (BI), Maximum Likelihood (ML), and Neighbour-Joining (NJ). BI and ML were performed, using the GTR evolutionary model and NJ using K2P distances. BI was performed with MrBayes ver. 3.2.6 (Ronquist & Huelsenbeck 2003); the data set was run twice, using four Markov chains for ten million generations; trees were sampled every 500th generation, the first 2.5 million generations were discarded, and a 50% majority tree was obtained. ML analysis was performed in MEGA X (Kumar et al. 2018); support was assessed with 1000 bootstrap reiterations.
