Abstract :: and New Guinea (together referred to as ) were linked by land for much of the late Tertiary and share many biotic elements. However, New Guinea is dominated by rainforest, and northern Australia by savannah. Resolving patterns of biotic interchange between these two regions is critical to understanding the expansion and contraction of both habitat types. The green (Litoria caerulea) has a vast range across northern and eastern Australia and New Guinea. An assessment of mitochondrial and morphological diversity in this nominal taxon in New Guinea reveals two taxa. True Litoria caerulea occurs in disjunct savannahs of the , Central Province and across northern Australia, with very low genetic divergence, implying late Pleistocene connectivity. A previously unrecognised taxon is endemic to New Guinea and widespread in lowland swampy rainforest. Date estimates for the divergence of the new species suggest Pliocene connectivity across lowland tropical habitats of northern Australia and New Guinea. In contrast, the new species shows shallow phylogeographic structuring across the central mountains of New Guinea, implying recent dispersal between the northern and southern lowlands. These results emphasise that the extent and connectivity of lowland and across northern Australia and southern New Guinea have undergone profound shifts since the late .



Etymology: The name mira is the feminine form of the Latin adjective , for surprised or , stemming from our surprise in discovering an undescribed member of the predominately Australian L. caerulea group occurring widely across lowland swampy rainforest in New Guinea.

Untangling vines of Vietnam

Top photo: Ahaetulla prasina, common vine snakes in Vietnam, can be found almost everywhere and they can be any color (green, yellow, silver). They prefer forestry areas.

Mid photo: they used to be Ahaetulla nasuta, they are usually green. But new research pointed out that A.nasuta is now a Sri Lanka thing. Every nasuta-look-a-like Ahaetulla (in other places) needs to be examinated more. That makes the vietnamese population nameless (as well as most of other SEA countries).

Bottom photo: Ahaetulla rufusoculara, new species of red eyed green vine snakes. They can be found in the some parts of the Mekong delta.

Las serpientes coralillo, corales o serpientes de coral pertenecientes a los géneros Micrurus y Micruroides se caracterizan por la presencia de anillos de colores variables (la mayoría).

•Presentan un tipo de dentición proteroglifa. Su veneno es neurotóxico, afecta principalmente al sistema nervioso.

•Son ovíparas.

•Se alimentan de pequeños vertebrados, artrópodos y de otras serpientes.

•El patrón de color RANA (Rojo-Amarillo-Negro-Amarillo) NO sirve en México para identificación de coralillos reales y falsas. La identificación debe ser dada por expertos.

•En México se reconocen 13 especies y 1 no descrita hasta el momento del género Micrurus, la mayoría son endémicas (Reyes-Velasco, 2020). La taxonomía puede cambiar según el autor.

•No recomendamos la manipulación de ninguna serpiente.

•Agradecimientos especiales a todos los investigadores y fotógrafos que tuvieron a bien ceder sus fotografías para este esfuerzo divulgativo
