Neooxyartes gen. nov. Type species: Neooxyartes zomproi sp. nov., by present designation.

Diagnosis. Medium-sized Necrosciinae. Body slender, unarmed, sparsely granulated. Head oval. Vertex flat. Occiput weakly convex. Antennae filiform and long, surpassing apices of forelegs. Pronotum rectangular. Mesonotum slender and elongate, parallel-sided, longer than combined length of pronotum, metanotum and median segment. Metanotum roughly as long as median segment. Abdomen cylindrical and unarmed. Female with a distinct spine-like praeopercular organ on seventh sternum. Anal segment with an emargination on posterior margin in both sexes. Female subgenital plate scoopshaped, distinctly notched posteriorly, apex surpassing or not surpassing posterior margin of anal segment. Male poculum cup-shaped, tapering posteriorly, apex pointed. Cerci flattened. Legs slender and unarmed. First tarsi with a cluster of bristles basally. Profemora distinctly incurved basally. Tegmina minute and scale-like. Alae small and rudiment-like. Capsule oval with rounded micropylar plate.

Distribution. Vietnam.

Remarks. Neooxyartes gen nov. is currently known only from Vietnam and is related to Oxyartes Stål, 1875 , but can be separated by smaller size, unarmed thorax and a cluster of bristles on the base of the first tarsi in both sexes, unarmed abdomen, posteriorly notched subgenital plate and distinct spine-like praeopercular organ on posteromedial area of seventh abdominal sternum in female, unarmed ventral carinae of femora in male and rounded micropylar plate and lacking capitulum on operculum in egg.

Etymology. The specific epithet of this new genus is derived from the Latin words ‘ Neo ’ (= new) and ‘ oxyartes ’ referring to the relationship with Oxyartes Stål, 1875 .
