The paper describes the mature larvae (L2) of Lathrobium alzonai, L. freyi and L. paceiendemic, depigmented, apterous and subanophthalmous rove beetles from the Eastern Alps in Italy (Coleoptera: Staphylinidae; Paederine)belonging to the subgenus Glyptomerus. The larva of Lathrobium pacei Piva, 1994 is described for the first time, whereas the larvae of L. alzonai Capra Binaghi, 1938 and L. freyi Koch, 1938 are redescribed. Detailed illustrations of their structural features are provided, and diagnostic larval - morphological characters for Lathrobium are proposed. Based on earlier published and new data, morphological comparisons, both intergeneric (between Lathrobium and Tetartopeus) and interspecific (between L. alzonai, L. freyi and L. pacei) within the subtribe Lathrobiina, are made. The principal differences among the genera and species involve particular structures of the head and their measurements. The generic status of Tetartopeus was confirmed. No clear differences in the external morphological structure between the larvae of Glyptomerus and Lathrobium s.str. were noted. The morphological structure of L. alzonai larvae differed significantly from that of the larvae of the other two species. The differences relate mainly to the much larger body size of L. alzonai, the shape of the head with its relatively narrow neck, the details of the mouthparts structure and the distinct elongation of its antennae, maxillary palps, labial palps, some parts of the legs and urogomphi. Distribution of all known Italian glyptomeroid species of the genus Lathrobium is also given.
本文描述了来自意大利东阿尔卑斯山的特有种 Lathrobium alzonai、L. freyi 和 L. pacei 的成熟幼虫（L2），它们是无色、无翅和亚眼的隐翅虫（鞘翅目：隐翅虫科；拟步行虫科），属于 Glyptomerus 亚属。首次描述了 Lathrobium pacei Piva，1994 的幼虫，而 Lathrobium alzonai Capra Binaghi，1938 和 L. freyi Koch，1938 的幼虫则重新进行了描述。详细说明了它们的结构特征，并提出了用于鉴定 Lathrobium 的幼虫形态特征。基于早期发表的和新的数据，进行了形态比较，包括种间（Lathrobium 和 Tetartopeus 之间）和种内（Lathrobium alzonai、L. freyi 和 L. pacei 之间）的比较，均在 Lathrobiina 亚科内进行。属和种之间的主要差异涉及头部的特定结构及其测量值。Tetartopeus 的属地位得到了确认。在 Glyptomerus 和 Lathrobium s.str.的幼虫的外部形态结构上没有明显的差异。L. alzonai 幼虫的形态结构与其他两种幼虫的形态结构有很大的不同。差异主要与 L. alzonai 较大的体型、相对狭窄的颈部形状、口器结构的细节以及触角、下颚须、下唇须、一些腿部和生殖肢的明显伸长有关。还给出了所有已知意大利 Glyptomeroid 属 Lathrobium 物种的分布情况。
