![]() ![]() We also provide an updated dichotomous key for the genus. Our work is the most comprehensive phylogenetic analysis of the genus and the first study using μCT scanning for comparative morphology of Toxicocalamus. ![]() loriae clade 3 (sensu Strickland et al., 2016), T. The directed forward morphotype was shared by T. Dogs take in the infected copepods through contaminated food or water, the larvae grow and mature into adult worms inside the dogs bodies, and then, ultimately, erupt through the skin to release new larvae into water sources where they can continue to affect humans. Toxicocalamus goodenoughensis was found to have a sickle-shaped and directed forward postfrontal bone. Guinea worm affects dogs, for example, much like humans. Micro-computed tomography (μCT) scanning revealed the presence of distinctive variation in postfrontal bone morphologies, with three morphotypes exhibited within the genus: directed forward, directed lateral/perpendicular to cranium, and absent. Coalescent-based species delimitation found the new species to be uniquely delimited from all other taxa ( n = 13) in all combinations of parameters settings. goodenoughensis is sister to another D'Entrecasteaux endemic, T. uniform light brown), and >175 ventral scales. medium brown), dark brown mottling on yellow ventral scales, darkening toward cloaca (vs. unbanded uniform nape), a dark gray-brown dorsum (vs. divided), pale yellow markings on supralabials (vs. pachysomus Kraus, 2009, but it differs by having undivided nasal scales completely surrounding nares (vs. Toxicocalamus goodenoughensis morphologically most closely resembles T. sp., endemic to Goodenough Island of the D'Entrecasteaux Archipelago. Morphology and DNA sequences are used to describe a new species of New Guinea Worm-Eating Snake (Elapidae: Toxicocalamus Boulenger, 1896) from Papua New Guinea: Toxicocalamus goodenoughensis n. ![]()
