美拉尼西亚的盲蛇属Gerrrhopilus已经很少收集或研究。我检查了分配在博物馆的标本，以Gerrhopilus inornatus，并发现相当大的形态多样性，其中表明存在多个物种。我重新描述G。inornatus（Boulenger）的正模标本和一个额外的标本，我描述了六个新种的标本目前归入该名称下，巴布亚新几内亚：Gerrhopilus flavinotatus sp. nov.，罗莱盖盲蝽Gerrhopilus lorealis sp. nov.巴布亚盖盲蝽Gerrhopilus papuanorum sp. nov. n.多腺盖盲蝽，斯氏长柄叶蝉Gerrhopilus slapcinskyi sp. nov.，每种目前仅从1-3个标本中已知，除两个标本外，所有标本仅在单一地点已知。除了鳞片数量、习性和颜色模式等传统信息外，我还发现头盾中表皮腺体的数量和分布对区分物种特别有用。近年来，已确认的美拉尼西亚Gerrhopilus的数量大幅增加，但该地区对这些蛇的采样很少，预计在调查可以更有效地针对这些神秘的蛇时，将确定更多的物种。
Melanesian blindsnakes of the genus Gerrhopilus have been little collected or researched. I examined specimens assigned in museums to Gerrhopilus inornatus and found considerable morphological diversity among them that indicates the presence of multiple species. I redescribe G. inornatus (Boulenger) based on the holotype and one additional specimen, and I describe six new species among specimens currently subsumed under that name from Papua New Guinea: Gerrhopilus flavinotatus sp. nov., Gerrhopilus lorealis sp. nov., Gerrhopilus papuanorum sp. nov., Gerrhopilus polyadenus sp. nov., Gerrhopilus slapcinskyi sp. nov., and Gerrhopilus wallachi sp. nov. Each species is currently known from only 1–3 specimens, and all but two are known only from single localities. In addition to traditional information on scale counts, habitus, and color patterns, I found the numbers and distributions of epidermal glands among the head shields to be especially useful for discriminating among species. The number of recognized Melanesian Gerrhopilus has increased tremendously in recent years, but the region has been poorly sampled for these snakes, and it is to be expected that additional species will be identified at such time as surveys can more effectively target these cryptic snakes.
