New records are given for M. foedata (Brunner von Wattenwyl, 1907) from Pu Mat National Park and Ke Go Nature Reserve, extending the distribution of the species further to the south in Central Vietnam. Keywords: Phasmatodea, Medaurini, Clitumnini, Vietnam, China, Global Taxonomic Initiative Introduction We have recently described the genus Medauromorpha Bresseel & Constant, 2017 in the tribe Medaurini (Phasmatidae: Clitumninae) to include three species from North Vietnam and southern China: M. baviensis Bresseel & Constant, 2017, M. foedata (Brunner von Wattenwyl, 1907) and M. regina (Brunner von Wattenwyl, 1907) (BRESSEEL & CONSTANT, 2017). The identification of specimens of stick insects collected during a recent expedition in the framework of the Global Taxonomic Initiative project “A step further in the entomodiversity of Vietnam”, in July 2017, revealed two new locations for M. foedata that extend the distribution of the species to Central Vietnam. The examination of the female holotype of Ramulus augustus (Carl, 1913) showed that the species is a junior synonym of M. regina. The present paper aims to provide the new records of M. foedata together with an updated distribution map, to illustrate live specimens and eggs of the respective new populations, and to propose R. augustus as a junior synonym of M. regina. Material and methods Due to their nocturnal behaviour, like most Phasmida, the specimens of Medauromorpha were collected at night. A light-weight and water-proof Petzl MYO RXP head torch was used during collecting. The females were kept alive in a mesh pop up cage (Exo Terra explorarium™) for producing eggs. The specimens were euthanized by an injection with ethanol, stored in airtight plastic “zip”-bags in wood chips (used in rodent cages) and 3 CONSTANT J. & BRESSEEL J. Medauromorpha (Phasmatidae, Clitumninae) sprinkled with etylacetate (EtOAc) to prevent rotting, mould and keeping the specimens flexible. The bags were frozen on arrival and the specimens mounted later on. The photographs of the collection specimen were taken with a Canon 700D camera equipped with a Sigma 50 mm Macro lens, these of the wild specimens with a Sony DSC-H300 camera and these of the eggs with a Leica EZ4W stereo-microscope with an integrated camera, and stacked with CombineZ software. They were optimized with Adobe Photoshop CS3. Observations were done with a Leica MZ8 stereo-microscope. The distribution map was produced with SimpleMappr (SHORTHOUSE, 2010).
