Robineau-Desvoidy, 1830 is the most diverse genus in the family Fanniidae (Diptera), with 288 species, many of which are include many of sanitary, economic and legal interest. The morphological homogeneity within the genus often makes species determination difficult. The best option for correct identification is to combine molecular and morphological analyses. The variation in the shape of a selection of body characters can be assessed by Geometric Morphometrics using the head as an innovative structure. Sex must be accounted for as a key covariate in this kind of study, since , as many other Diptera, has a sexually dimorphic head structure, with holoptic males and dicoptic females. Firstly, we analysed a set of sp. specimens sampled across the Iberian Peninsula (2012-2015), of which (Wiedemann, 1830) was found to be the most abundant species. Our analyses provide significant morphological information. exhibits clear intraspecific morphometric variation along an Iberian-wide East-West axis. A similar pattern emerged when comparing a laboratory-bred colony and wild samples.
罗比诺-德沃伊迪属（Robineau-Desvoidy，1830年）是厕蝇科（双翅目）中物种最为多样的属，有288个物种，其中许多具有卫生、经济和法律方面的研究价值。该属内形态上的同质性常常使物种鉴定变得困难。正确鉴定的最佳选择是将分子分析和形态分析相结合。可以通过几何形态测量学，以头部作为一种创新结构，来评估一系列身体特征形状的变化。在这类研究中，必须将性别作为一个关键协变量来考虑，因为与许多其他双翅目昆虫一样，该属具有两性异形的头部结构，雄性为合眼式，雌性为离眼式。首先，我们分析了一组于2012年至2015年在伊比利亚半岛采集的 属标本，其中（维德曼，1830年）被发现是最为常见的物种。我们的分析提供了重要的形态学信息。 在伊比利亚半岛东西向轴线上呈现出明显的种内形态测量变异。在比较实验室培育群体和野生样本时也出现了类似的模式。
