左右不对称是昆虫交配器官中常见的现象。尽管人们提出了生殖器不对称的多种原因，但我们提出了这样的问题：不对称是否可能促进甚至加速物种间生殖器的形态分化。我们在金龟子裂殖属中测试了这一假设，该属包括具有对称和不对称雄性生殖器的物种。对 99 个南非样本（包括 34 个物种和 5 个外类群）的线粒体和核核糖体 DNA 序列数据（cox1、rrnL 和 28S）推断，在其系统发育背景下进行了形态计量分析。使用最大似然和贝叶斯分析重建树木。通过量化参数的形状差异，使用广义普罗克拉斯特分析（GPA）来分析雄性交配器官的不对称程度和变化。我们发现所研究物种之间的不对称程度存在连续转变。祖先状态重建揭示了裂殖龟参数不对称的多重起源和高度进化可塑性。然而，参数形状分化的进化速率与参数不对称程度之间没有发现显着相关性，因此我们得出结论，裂殖龟的生殖器不对称不会增加生殖器形状分化的速率。
Left–right asymmetry is a frequently encountered phenomenon in the copulation organs of insects. While various causes have been proposed for genital asymmetry, we raise the question of whether asymmetry might facilitate, or even accelerate, morphological divergence of genitalia between species. We tested this hypothesis in the scarab chafer genusSchizonycha, which comprises species with symmetric as well as asymmetric male genitalia. Morphometric analyses were conducted in the context of their phylogeny, inferred from mitochondrial and nuclear ribosomal DNA sequence data (cox1,rrnL, and 28S) for a sample of 99 South African specimens,including 34 species and 5 outgroup taxa. Trees were reconstructed with maximum likelihood and Bayesian analysis. The extent of asymmetry and the variation of male copulation organs were analyzed with Generalized Procrustes analysis (GPA), by quantifying shape divergence of the parameres. We found a continuous transition in the degree of asymmetry among the investigated species. Ancestral state reconstruction revealed multiple origins and a high degree of evolutionary plasticity of paramere asymmetry inSchizonycha. However, no significant correlation between evolutionary rates of paramere shape divergence and the degree of paramere asymmetry was found, and so we conclude that asymmetric genitalia inSchizonychado not increase the rate of genital shape divergence.
