Data from: Taxonomic revision of genus Ablattaria Reitter (Coleoptera, Silphidae) employing geometric morphometrics

The genus Ablattaria Reitter, 1884 (Coleoptera: Silphidae: Silphinae) is revised. Four taxa are recognized as valid species: Ablattaria arenaria (Kraatz, 1876), A. cribrata (Ménétries, 1832), A. laevigata (Fabricius, 1775) and A. subtriangula Reitter, 1905. Ablattaria laevigata var. meridionalis Ganglbauer, 1899 is newly treated as a junior subjective synonym of A. laevigata. Lectotypes are designated for Phosphuga arenaria Kraatz, 1876, Ablattaria arenaria var. punctigera Reitter, 1884, Ablattaria arenaria var. alleoni Portevin, 1926, Silpha cribrata Ménétries, 1832, Silpha laevigata Fabricius, 1775, Silpha gibba Brullé, 1832, Ablattaria gibba var. costulata Portevin, 1926, Ablattaria gibba var. distinguenda Portevin, 1926, Ablattaria gibba var. punctata Portevin, 1926 and Ablattaria subtriangula Reitter, 1905. The distribution of all taxa is mapped, based on material examined. Geometric morphometric methods were used to evaluate shape variability in Ablattaria. Results indicated sexual dimorphism in all species. Shape inconsistency was found between the sexes of all taxa when tested independently. The first two relative warp axes indicated 65.17% shape variation in males and 65.72% in females. Canonical variate analysis separated the taxa studied. There was minimal overlap between some groups in both sexes. Differences in body shape between populations of A. laevigata from Central Europe, Italy and Greece + Turkey were also examined. Relative warps implied 58.01% shape variability on both axes in males and 64.78% in females. CVA revealed noticeable overlaps between the groups, although the Italian population demonstrated a higher separation in both sexes.

本次对1884年Reitter建立的阿扁隐翅虫属（Ablattaria Reitter, 1884，鞘翅目Coleoptera:葬甲科Silphidae:葬甲亚科Silphinae）开展了分类修订。研究确认该属下共有4个有效物种：砂生阿扁隐翅虫（Ablattaria arenaria (Kraatz, 1876)）、刻点阿扁隐翅虫（A. cribrata (Ménétries, 1832)）、光滑阿扁隐翅虫（A. laevigata (Fabricius, 1775)）以及三角阿扁隐翅虫（A. subtriangula Reitter, 1905）。原Ablattaria laevigata var. meridionalis Ganglbauer, 1899被新处理为光滑阿扁隐翅虫（A. laevigata）的主观次同物异名。本研究为以下类群指定了选模标本：Phosphuga arenaria Kraatz, 1876、Ablattaria arenaria var. punctigera Reitter, 1884、Ablattaria arenaria var. alleoni Portevin, 1926、Silpha cribrata Ménétries, 1832、Silpha laevigata Fabricius, 1775、Silpha gibba Brullé, 1832、Ablattaria gibba var. costulata Portevin, 1926、Ablattaria gibba var. distinguenda Portevin, 1926、Ablattaria gibba var. punctata Portevin, 1926以及三角阿扁隐翅虫（Ablattaria subtriangula Reitter, 1905）。研究基于检视的标本材料，对所有分类单元的分布范围进行了绘图标注。本研究采用几何形态测量学方法（geometric morphometric methods）评估了阿扁隐翅虫属的形态变异情况，结果显示所有物种均存在性二型现象；单独检验各分类单元的雌雄个体时，均发现二者形态存在显著差异。前两轴相对扭曲主成分轴分别解释了雄性65.17%、雌性65.72%的形态变异。典型变量分析（Canonical variate analysis, CVA）可将本次研究的所有分类单元区分开来，部分类群的雌雄个体间仅存在极小的重叠区域。此外，本研究还检视了中欧、意大利以及希腊+土耳其的光滑阿扁隐翅虫种群间的体型形态差异，相对扭曲分析显示，两性的前两轴共解释了58.01%的形态变异，雌性则为64.78%。典型变量分析结果显示各群体间存在一定的重叠，但意大利种群在雌雄个体中均表现出更高的分离度。
