872187FA0B70FF8CFF76B0FBFA5B280B.taxon	diagnosis	Diagnosis. Small to medium-sized. Dull colouration, usually brown. Body cylindrical, slender and elongate. Head oblong or oval. Thorax rough, usually wrinkled and granulated, partially tuberculate and / or spinose. Mesonotum multi spinose and obscurely or distinctly elevated with a tuberculate or spinose hump medially. Abdomen cylindrical, wrinkled and granulated. Seventh sternum with praeopercular organ in female. Female subgenital plate scoop-shaped. Male poculum cup-shaped. Supra-anal plate indistinct. Cerci short and flattened. Legs robust, slender and long, femora thicker than corresponding tibiae, with indistinct armature. Anteroventral and posteroventral carinae of femora with or lacking small spines or serrations near apices. Apterous. Egg capsule oval with oval micropylar plate. Distribution. China, India, Japan, Malaysia and Vietnam. China and Vietnam is the distribution centre. Although there is no record of Neohirasea in Cambodia, Laos, Myanmar and Thailand, further collecting of specimens in various localities in these countries may discover certain populations in the region. Remarks. Currently, twenty-two species and thirteen subspecies are recognised in Neohirasea. A key to the species and subspecies of the genus from Vietnam is provided. The males of N. cochinchinensis (Redtenbacher, 1908) and N. stephanus (Redtenbacher, 1908) are unknown and not included in the key.	en	Ho, Wai-Chun George (2018): The genus Neohirasea Rehn (Phasmatodea: Diapheromeridae: Necrosciinae) from Vietnam.
