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.

FIGURE 10. Habitat of Stegonotus nancuro sp. nov. in the Nancuro area, Manatuto Municipality, Timor-Leste. (A) Typical tropical moist forest habitat, showing a humus substrate, dense growth, and decaying logs. (B) Near the beach (the bright area at right in the image), there are few larger trees and a thick, shrubby undergrowth. (C) Access road into the Nancuro area, showing the dense vegetation and undergrowth. (D) The edge of the grassland, showing the height of the grasses against one of the expedition vehicles.

Scales in (D') include rostral (R), numbered supralabials (SL), mental (M), numbered infralabials (IL), anterior genials (AG), posterior genials (PG), gulars (G) with Roman numerals, and ventrals (V).
