The scattered information regarding the Australo‐Papuan noctuid genus Pachythrix Turner, 1942 is consolidated to provide an overview of this little‐known group of bright green and black‐coloured moths. Nomenclatural comments are provided to challenge current opinion that the genus is based on a misidentified type species. Current evidence supporting its systematic relationships and subfamilial placement is reviewed, showing that the present concepts of genera like Thalatha Walker, 1862 and Pachythrix itself are polyphyletic. Pachythrix mniochlora (Meyrick, 1889) is shown to be misplaced in the genus. Pachythrix chlorophylla sp. nov. from the Bismarck Archipelago is described. This species is the first member of the genus to have been recorded from the Bismarck Archipelago, the others occurring in New Guinea and Australia. The new species can easily be distinguished from its congeners superficially by more extended green areas on the fore wing and fewer black, subterminal wedges. Diagnostic criteria and illustrations of all species currently assigned to the genus are provided.

审查Pachythrix Turner属的森林栖夜蛾类，1942年（鳞翅目：夜蛾科）：重新评估the斯马群岛的物种类型并描述新物种

有关Australo-Papuan夜蛾属Pachythrix Turner，1942年的零散信息得到了合并，以提供这一鲜为人知的鲜绿色和黑色蛾类的概述。提供术语命名注释来质疑当前的观点，即该属基于错误识别的类型物种。审查了支持其系统关系和亚家族定位的当前证据，表明当前的属概念（如Thalatha Walker，1862年和Pachythrix本身）是多系的。Pachythrix mniochlora（Meyrick，1889）被证明在属中放错了位置。Pachythrix phylphylla sp。十一月来自the斯麦群岛的描述。该物种是the斯麦群岛记录的该属的第一个成员，其他物种则发生在新几内亚和澳大利亚。通过在前翼上扩展的绿色区域和更少的黑色亚末端楔形，可以很容易地从表面上区分新物种与其同类。提供了当前分配给该属的所有物种的诊断标准和插图。
