Fig. 5 in Rediscovery of the rare Star Mountains Worm-eating Snake, Toxicocalamus ernstmayri O'Shea et al., 2015 (Serpentes: Elapidae: Hydrophiinae) with the description of its coloration in life

Fig. 5. Distinguishing Toxicocalamus from Micropechis. (A, A')Holotype of T. ernstmayri (MCZ R-145946) from Wangbin, Western Province, PNG. (B, B') Holotype of T. grandis (BMNH 1946.1.18.34) from Setakwa River, Papua Province, Indonesian New Guinea. (C, C') Yellow phase of Micropechis ikaheka (BMNH 1909.4.30.12) from the FakFak Peninsula, West Papua Province, Indonesian New Guinea. Color-coding of head scalation includes six supralabials (orange), a single anterior temporal (yellow), two posterior temporals (blue), and a temporolabial (red). The individual we report here clearly has the same head scute arrangement as T. ernstmayri.

Fig. 2 in Rediscovery of the rare Star Mountains Worm-eating Snake, Toxicocalamus ernstmayri O'Shea et al., 2015 (Serpentes: Elapidae: Hydrophiinae) with the description of its coloration in life

Fig. 2. The first live individual of Toxicocalamus ernstmayri, observed and photographed in broad daylight at the Ok Tedi Mine, North Fly District, Western Province, Papua New Guinea. (A) The individual's serendipitous crossing of a 747 mm wide tire track allowed an approximation of its total length as near 850 mm. (B) The snake moves in a straight line across open ground. (C) Slower movement across a rubble pile allowed a more detailed examination of head and body scales (see Fig. 4). (D) The individual moving under the tracks of a stationary digger.

Fig. 1. Satellite map (derived from Google Earth) of the southern Star Mountains, North Fly District, Western Province, Papua New Guinea, with yellow dots on the larger map indicating two localities (Wangbin and Ok Tedi Mine), approximately 13 km apart, where Toxicocalamus ernstmayri has been recorded. The main town is Tabubil at the confluence of the Ok Tedi and Ok Mani, which flow into the Fly River. Scale = 5 km. The inset map illustrates the location of the larger map in relationship to the rest of New Guinea.

Fig. 4. Confirming the individual's identification as Toxicocalamus ernstmayri. (A) Close-up of the snake shown in Fig. 2C with insets B, C, and D indicated. (B, B') Head and neck in extreme close-up. Color coding of head scalation includes six supralabials (orange), one anterior temporal (yellow), and two posterior temporals (blue), but no temporolabial (see Fig. 5). The head scutes appear to comply with the colubrid-elapid nine dorsal scute arrangement (i.e., two internasals, two prefrontals, one frontal, two supraoculars, and two parietals; therefore lacking any head scute fusion, although this is difficult to discern from the magnified image with accuracy. (C, C') Based on the visible dorsal scales, the dorsal scale count on the anterior body is 15. The count is achieved by locating the vertebral scale row and counting down to the lowest dorsal scale row (eight scales), doubling the count, and subtracting one scale to account for the single vertebral scale row. (D, D') The dorsal scale count at midbody, performed as described for the previous panel, is also 15.

(star) and localities for its putative close relatives: T. loriae (circles), T. mintoni (triangle), T. nigrescens (diamonds), T. pachysomus (square), and T. "loriae" Clade 4 (hexagon) Contours are white <1000 m, pale gray 1000–1500 m, medium gray 1500–2000 m, and dark gray>2000 m.

(2018) with the names of recently described or identified species incorporated in place of the clade numbers of that paper. Clades 2, 3, and 4 represent lineages of T. "loriae" sensu lato that remain to be resolved.
