Abstract

The phylogenetic placement of the enigmatic subtribe Stenolamina is investigated based on the analysis of four molecular loci (CAD, wg, 28S, 12S). Historically, the position of Stenolamina remained unfixed, and was listed as incertae sedis within the darkling beetle subfamily Blaptinae. Molecular data render Stenolamina as a separate lineage within the tribe Opatrini. The morphology and distribution of Stenolamina are reexamined. Scanning electron microscopy revealed that Stenolamina shares the synapomorphic Opatrini protrochanter structure seen in all other members of the tribe. Furthermore, unique antennal sensoria (placoid / stenolamoid) are reported for Stenolamina – this feature is distinct from all other Blaptinae. This paper presents the first morphological definition of Stenolamina. Finally, Stenolamus borowieci sp. nov. is described from the surroundings of Port Nolloth (South Africa). The material examined for this species displayed a striking type of sexual dimorphism, which is omnipresent within Stenolamina (females with acute basal angles of the pronotum).

欢迎回家:一个神秘亚部落Stenolamina Koch的系统发育定位和分类，1956(拟甲科:黑甲科:粉甲)

通过对四个分子位点(CAD, wg, 28S, 12S)的分析，研究了神秘的Stenolamina亚族的系统发育定位。在历史上，Stenolamina的位置一直不固定，被列为黑甲虫亚科中的incertae sedis。分子数据显示，Stenolamina是奥帕特里尼部落中的一个独立谱系。重新研究了窄管线虫的形态和分布。扫描电子显微镜显示，Stenolamina共享在部落所有其他成员中看到的突触性Opatrini原转子结构。此外，据报道，窄足虫独特的触角感觉器官(placoid / stenolamoid) -这一特征与所有其他Blaptinae不同。本文给出了窄藻的第一个形态学定义。最后，在南非诺洛斯港附近发现了一种小龙虾(Stenolamus borowieci sp. 11 .)。对这一物种的研究材料显示了一种显著的两性二态性，这种二态性在Stenolamina(雌性具有尖锐的前角)中无处不在。
