New Guinea is the heart of Melanesia and truly megadiverse in terms of flora and fauna. This diversity has often been attributed to complex geological processes that have shaped the composite New Guinea landmass, especially over the past c. 25 million years. Previously, we have empirically shown that the massive central orogeny during the past few million years was one important motor for lineage diversification. We have revealed complex patterns of habitat shifts from highlands to lowlands and back, and a comparably recent, massive, and ongoing diversification of aquatic beetles across New Guinea. Here, we focus on an open question, i.e. the timing of diversification events in the presumably older west Papuan central highlands and the possible existence of ancient lineages in the Ophiolite belt attached to these mountains. This area has never been visited by biologists before, and we see a unique opportunity to virtually fill a white spot on the map and provide data to better understand the role of different geological terranes in the evolution of a diverse biota.

新几内亚是美拉尼西亚的心脏，在植物群和动物群方面真正具有巨大的多样性。这种多样性通常归因于复杂的地质过程，这些过程塑造了新几内亚的复合大陆，特别是在过去的c。两千五百万年。在此之前，我们已经经验表明，在过去的几百万年中，巨大的中央orthodox是血统多样化的一个重要马达。我们已经揭示了复杂的模式，从高地到低地和背部的栖息地转移，和一个最近的，大规模的，并持续多样化的水生甲虫在新几内亚。在这里，我们专注于一个悬而未决的问题，即多元化事件的时间在大概老西巴布亚中央高地和可能存在的古老的血统在蛇绿岩带连接到这些山脉。这一地区以前从未被生物学家访问过，我们看到了一个独特的机会，可以在地图上几乎填满一个白色斑点，并提供数据，以更好地了解不同地质生物在多样化生物群进化中的作用。
