Abstract

Beetles occupy a vast amount of different ecological roles in both terrestrial and freshwater ecosystems. The often very specialised morphology of the adults can frequently be associated with their specific roles. Yet, the ecologically independent larvae of the same species are often unknown; this applies even more so to fossils. Here we report a new fossil beetle larva preserved in Mexican amber. The beetle larva was documented via digital microscopy and X-ray micro-computed tomography (X-ray µCT). The observed features, especially of the trunk, but also the maxillo-labial complex as well as the moulting suture of the head capsule are reminiscent to those of larvae of variegated mud-loving beetles, Heteroceridae. The trunk end is tube-like and protrudes ventro-terminally from abdomen segment 9. While present in other beetle lineages, this morphology is in these lineages, for example, not combined with a simple moulting suture. Some features potentially further supporting an interpretation as a larva of Heteroceridae are not accessible. The interpretation yet remains the most compatible one. Assuming a similar life style to modern larvae of Heteroceridae indicates an original lifestyle associated with running waters, but not within these. Heteroceridae is an ingroup of Byrrhoidea; the fossil record of byrrhoidean larvae is still very scarce. The new fossil hence adds a rare ecological function to the Miocene amber fauna, representing the first fossil record of a larva of Heteroceridae and expanding the fossil record of byrrhoidean larvae.

保存在2300万年前的墨西哥琥珀中的一只小甲虫幼虫:可能是一种未成熟的杂色喜泥甲虫的首次化石记录
甲虫在陆地和淡水生态系统中扮演着大量不同的生态角色。成年人通常非常专业的形态往往与他们的特定角色有关。然而,同一物种的生态独立幼虫往往不为人知;化石更是如此。在这里,我们报道了一个保存在墨西哥琥珀中的新甲虫幼虫化石。通过数字显微镜和X射线显微计算机断层扫描(X射线µCT)记录了甲虫幼虫。观察到的特征,特别是躯干的特征,还有上嘴唇复合体以及头囊的蜕皮缝合线,让人想起了异足虫科的杂色喜泥甲虫幼虫的特征。主干端部是管状的,并且从腹部段9向腹端突出。虽然存在于其他甲虫谱系中,但这种形态存在于这些谱系中,例如,没有与简单的蜕皮缝合线结合。一些可能进一步支持异足目幼虫解释的特征是不可获得的。迄今为止,这种解释仍然是最兼容的。假设其生活方式与异足目现代幼虫相似,则表明其原始生活方式与流水有关,但与流水无关。异齿龙科是龙齿龙科的一个类群;痔疮科幼虫的化石记录仍然非常稀少。因此,新化石为中新世琥珀动物群增加了一种罕见的生态功能,代表了异齿目幼虫的第一个化石记录,并扩大了Byrrhoidea幼虫的化石记录。

期刊介绍: The Boletín de la Sociedad Geológica Mexicana is a completely free-access electronic journal published semi-annually that publishes papers and technical notes with its main objective to contribute to an understanding of the geology of Mexico, of its neighbor areas, and of geologically similar areas anywhere on Earth’s crust. Geology has no boundaries so we may publish papers on any area of knowledge that is interesting to our readers. We also favor the publication of papers on relatively unfamiliar subjects and objectives in mainstream journals, e.g., papers devoted to new methodologies or their improvement, and areas of knowledge that in the past had relatively little attention paid them in Mexican journals, such as urban geology, water management, environmental geology, and ore deposits, among others. Mexico is a land of volcanos, earthquakes, vast resources in minerals and petroleum, and a shortage of water. Consequently, these topics should certainly be of major interest to our readers, our Society, and society in general. Furthermore, the Boletín has been published since 1904; that makes it one of the oldest scientific journals currently active in Mexico and, most notably, its entire contents, from the first issue on, are available online.
