FIGURE 7 in A new species of jumping pitviper of the genus Atropoides (Serpentes: Viperidae: Crotalinae) from the Sierra de Botaderos and the Sierra La Muralla, Honduras
FIGURE 7. Phylogenetic relationship among Atropoides species, showing the position of Atropoides indomitus (adapted from Castoe et al. [2005] with permission). Branch lengths are scaled to genetic distance among sequences, as indicated by the scale bar. The phylogenetic estimate is based on the preferred tree estimated from 1405 bp of mitochondrial DNA (including cyt-b and ND4 genes) using Bayesian Markov chain Monte-Carlo methods, with models of nucleotide substitution partitioned by codon position and by gene region. Bayesian posterior probability support for nodes> 94% are given, and nodes receiving 100% posterior probability are indicated with gray circles.

FIGURE 9 in A new species of Stegonotus (Serpentes: Colubridae) from the remnant coastal forests of southern Timor-Leste
FIGURE 9. Photographs of four live individuals of Stegonotus nancuro sp. nov. to show color variation. Each snake is shown in full body view (left column) with a close-up of the anterior body (right column). The unusual color scheme, in which there is a gradation of brown to cream in both individual scales as well as along the lateral side of the body, is clearly visible. Shown are the holotype, USNM 580549 (A, B), the two adult paratypes, USNM 579383 (C, D) and MCZ R-192767 (E, F), and the juvenile paratype, USNM 580550 (G, H). It is noteworthy that the juvenile shows differences in both head morphology (by the large eyes relative to overall head size) and coloration (a slightly darker, grayer overall color regimen).
FIGURE 8 in A new species of Stegonotus (Serpentes: Colubridae) from the remnant coastal forests of southern Timor-Leste
FIGURE 8. Lateral head views of the paratypes of Stegonotus nancuro sp. nov., shown as both photographs and line drawings in left and right aspects, in the left and right image columns, respectively. Shown are USNM 579383 (A, A', B, B'), MCZ R- 192767 (C, C', D, D'), and USNM 580550 (E, E', F, F'). The juvenile paratype has a noticeably different head shape from the eyes forward, with a snout that is shorter relative to eye size than in the other specimens. Images not to scale.
FIGURE 2 in A new species of Stegonotus (Serpentes: Colubridae) from the remnant coastal forests of southern Timor-Leste
FIGURE 2. Schematic dorsal head views of USNM 580549, the holotype of Stegonotus nancuro sp. nov., shown to illustrate the pattern of head scales and other important characters. Scale labels in (A) include internasals (IN), internasal suture (InS – distance between Points 1 and 2), prefrontals (PF), prefrontal suture (PfS – distance between Points 3 and 4), frontal (F), frontal length (FL – distance between Points 4 and 5), frontal width (FW), supraoculars (SO), postoculars (PO), parietals (P), external skull length (ESL – distance between Points 3 and 8), and parietal suture (ParS – distance between Points 5 and 8). The numbers 1–8 in (B) represent key reference points for measurements and angles as follows: (1) anteriormost internasal contact point; (2) posteriormost internasal contact point; (3) anteriormost prefrontal contact point; (4) posteriormost prefrontal contact point and anteriormost point on the frontal; (5) point on the frontal, where the posterior edge of the frontal meets the parietal suture; (6) the two points on either side of the head where frontal, parietal, and supraocular meet; (7) the two points on either side of the head where parietal, supraocular, and postocular meet; and (8) posteriormost parietal contact point. The posterior frontal angle (PF∠) is produced by a vertex at Point 5 with rays extending from Point 5 through Point 6 on either side of the head. The anterior parietal angle (AP∠) is produced by a vertex at Point 6 and two rays, one extending from Point 6 through Point 5 and the other from Point 6 through Point 7. The ray including Points 6 and 7 is the lateral ray, and its orientation relative to the midline of the head is of diagnostic value. The yellow line in (B) shows our method of evaluating the lateral ray, which can be oriented laterally (angle of the yellow line with the midline of the head = 90° ± 10°) or posterolaterally (the angle of the red line with the midline of the head <80°). The white anterior eye line (AE) intersects the anteriormost points of the eyes and is assessed by its position in relation to the anterior frontal suture ("behind," "same level," or "in front of").
FIGURE 6 in A new species of Stegonotus (Serpentes: Colubridae) from the remnant coastal forests of southern Timor-Leste
FIGURE 6. Dorsal head views of the paratypes of Stegonotus nancuro sp. nov., shown as both photographs and line drawings. Shown are USNM 579383 (A, A'), MCZ R-192767 (B, B'), and USNM 580550 (C, C'). The juvenile paratype (C, C') shows noticeable differences in head proportions, with eyes larger and more protruding relative to head size than in the other specimens. Scale proportions appear almost identical to those of the adults. Images not to scale.
FIGURE 1 in A new species of Stegonotus (Serpentes: Colubridae) from the remnant coastal forests of southern Timor-Leste
FIGURE 1. Distribution of Stegonotus species in south-central Wallacea. Islands relevant to this study occupy a geographic area that stretches from some of the northern Moluccas in the northeast to Timor and Sumba Islands in the southwest. Species distribution is color-coded and islands with confirmed species records are numbered. These include S. batjanensis (encircled in yellow), found on Morotai (1), Halmahera (2), Ternate (3), Tidore (4), Kasiruta (5), Bacan (6), and Obi (7); S. modestus (green), on Seram (8), Buru (9), and Ambon (10); S. keyensis (blue), endemic to the Kei Islands (11); S. aruensis (purple), endemic to the Aru Islands (12); S. florensis (orange), endemic to Flores Island (13); S. sutteri (brown), endemic to Sumba Island (14); and S. lividus (teal), with its type locality on Semau Island (15). In the map of Timor-Leste (inset), the two localities from where S. nancuro sp. nov. is known include the type locality (red star) and a coastal forest near Betano, Samé Municipality (red circle). The globe shows the position of the depicted region relative to Australia and mainland Asia.
