摘要

根据正在进行的 Amblyopinina 亚族系统发育研究，描述了两个新属 Chimalfus gen.由此产生的新组合是 Chimalfus brevis (Sáiz, 1971) comb.此外，还描述了一个新种 Chimalfus brunneus sp.此外，还描述了新种 Chimalfus brunneus sp.几何形态分析确定了所有修订种和新种的重要形态特征。主成分分析（PCA）和褶皱方差分析（procrustes ANOVA）提供了对所有特征的有效概述，突出了物种划分的关键形态特征。分析结果表明，头部和前胸的序列对物种划分具有重要意义。这些知识以及本研究采用的工作流程可应用于今后物种更丰富的 Amblyopinina 属的分类工作中。

Chimalfus and Liracoxa (Coleoptera: Staphylinidae: Staphylininae), two new genera from southern south America with a geometric morphometric evaluation of head and pronotal chaetotaxy

Based on the ongoing phylogenetic study of the subtribe Amblyopinina, two new genera are described, Chimalfus gen. nov. and Liracoxa gen. nov. to accommodate three species earlier misplaced in the genus Sphingoquedius. The resulting new combinations are Chimalfus brevis (Sáiz, 1971) comb. nov., Chimalfus discoideus (Fairmaire and Germain, 1862) comb. nov., and Liracoxa nana (Sáiz, 1971) comb. nov. Furthermore, a new species, Chimalfus brunneus sp. nov., is described. For each species, taxonomic descriptions, illustrations, distributions, and bionomics are provided. Geometric morphometric analysis identified morphologically significant traits for the delimitation of all revised and new species. Principal Component Analysis (PCA) and procrustes ANOVA offered an effective overview of all traits, highlighting key morphological characters for species delimitation. The analyses revealed that the chaetotaxy of the head and pronotum was significant for species delimitation. This knowledge, as well as the methodical workflow employed in this study, may be applied in future taxonomic work in the more species-rich genera of Amblyopinina.

期刊介绍： Zoologischer Anzeiger - A Journal of Comparative Zoology is devoted to comparative zoology with a special emphasis on morphology, systematics, biogeography, and evolutionary biology targeting all metazoans, both modern and extinct. We also consider taxonomic submissions addressing a broader systematic and/or evolutionary context. The overall aim of the journal is to contribute to our understanding of the organismic world from an evolutionary perspective. The journal Zoologischer Anzeiger invites suggestions for special issues. Interested parties may contact one of the editors.
