Disphaerobius Attems, 1926, the sole constituent genus of the subfamily Pterygoterginae, is synonymized with Pterygotergum Verhoeff, 1934 syn. nov., and is shown to comprise only two species: D. svenhedini (Verhoeff, 1934) comb. nov. ex Pterygotergum, and D. loricatus (Sseliwanoff, 1881) (= Lithobius magnificus Trotzina, 1895), both syn. nov. and comb. nov. ex Lithobius Leach, 1814. Disphaerobius is rediagnosed, both of its basically Central Asian species are redescribed from fresh material of both sexes, and their distributions are mapped. Disphaerobius svenhedini is newly recorded from S Kazakhstan and W Mongolia. New material of D. loricatus is also recorded. Sexual dimorphic characters in Lithobiomorpha are briefly discussed, these being considered especially strongly pronounced and unique in Disphaerobius.
1926年的Disphaerobius Attems是翼尾蛩亚科唯一的组成属，现被认定为与1934年的翼尾蛩属（Pterygotergum Verhoeff）同义（新同义名），且仅包含两个物种：斯文赫丁氏Disphaerobius（Disphaerobius svenhedini）（Verhoeff，1934），新组合，由翼尾蛩属转移而来；以及具甲Disphaerobius（Disphaerobius loricatus）（Sseliwanoff，1881）（=华丽石蜈蚣Lithobius magnificus Trotzina，1895），均为新同义名及新组合，由1814年的石蜈蚣属（Lithobius Leach）转移而来。对Disphaerobius进行了重新诊断，基于两性新鲜标本对其两个基本分布于中亚的物种进行了重新描述，并绘制了它们的分布图。斯文赫丁氏Disphaerobius在哈萨克斯坦南部和蒙古西部为首次记录。还记录了具甲Disphaerobius的新材料。简要讨论了石蜈蚣目的两性异形特征，这些特征在Disphaerobius中被认为尤为显著和独特。
