“…Since the anterior wing margin experiences the greatest air resistance in flight, it can be concluded that there is a clear trend to 'costalization' of anterior veins, that may confer the improvement aerobatic ability of Bombylius flies. Similar trends were discovered in dolichopodid (Chursina and Negrobov 2018) and simuliids fly (Pepinelli 2013).…”

“…Sexual size and shape dimorphism is a widespread phenomenon in dipteral insects, and has therefore generated interest in evolutionary biology (Richard 1927;McLachlan 1986;Sivinski and Dorson 1992;Gidaszewski et al 2009). Sexual size and shape dimorphism is often the result of the different life strategies, roles in reproduction of males and females or adaptation of sexes to different ecological niches (Shine 1990) and in some cases carried a clear phylogenetic signal (Houle et al 2003;Chursina and Negrobov 2018).…”

Chursina MA, Ruchin AB. 2018. A checklist of Bombyliidae (Diptera) from Mordovia, Russia and variation of wing shape in Bombylius species. Biodiversitas 19: 2147-2156. A checklist of Bombyliidae (Diptera) of Republic of Mordovia (Russia) is provided, based on material collected from 2008 to 2017. One hundred ninety specimens from 75 localities were collected. Fourteen of the twenty species are listed as belonging to the fauna for the first time. Intraspecific variation and sexual dimorphism in the wing shape of three species of the genus Bombylius Linnaeus, 1758 were investigated using geometric morphometric techniques. The analysis revealed that wing shape is a good discriminator of the species. In addition, significant sexual dimorphism were found: females of two of the three species had larger wings than males. The sex shape differences consisted mainly of сhanges in the placement of the CuA and A1, while interspecific wing shape variation distributed in more dimensions. There was no evidence for allometric relationships relating to sexual dimorphism and interspecific variation. Potential adaptive significance of interspecific and intersex variation in wing size and shape is discussed.

“…Thus, whereas in some species allometric variation is responsible of an important proportion of SShD (Gidaszewski et al 2009; de Camargo et al 2015); in other species, it exerts a marginal effect (Virginio et al 2015). Disparate roles have been detected even between species of the same genus (Chursina & Negrobov 2018;Gushki et al 2018). Previous studies detected allometric shape variation in Culicoides wings (Muñoz-Muñoz et al 2011, 2014.…”

“…Although shape is a highly dimensional multivariate trait, simpler shape variables are usually used to predict aerodynamic efficiency of wings due to conceptual and mathematical simplicity. One of the main measures of functional variation in wing shape is the length of the wing relative to the width, known as aspect ratio (AR; Hassall 2015;Chursina & Negrobov 2018). AR affects the aerodynamic force components by influencing the flow over the insect wing (Bhat et al 2019), and therefore its calculation yields fundamental data to underpin aerodynamic theory, helping to understand the effect of wing form on flight performance (Ray et al 2016).…”

Narrow versus broad: sexual dimorphism in the wing form of western European species of the subgenus Avaritia (Culicoides, Ceratopogonidae)

While wing form is known to differ between males and females of the genus Culicoides, detailed studies of sexual dimorphism are lacking. In this study, we analyze sex‐specific differences in the wing form of 5 species of the subgenus Avaritia, using geometric morphometrics and comparative phylogenetic methods. Our results confirm the existence of marked sexual dimorphism in the wing form of the studied species and reveal for the first time that while there is a shared general pattern of sexual shape dimorphism within the subgenus, sexual size dimorphism, and particular features of sexual shape dimorphism differ among species. Sexual shape dimorphism was found to be poorly associated to size and the evolutionary history of the species. The tight association of sexual shape dimorphism with aspect ratio suggests that the shape of the wing is optimized for the type of flight of each sex, that is, dispersal flight in females versus aerobatic flight in males. Moreover, the fact that interspecific shape differences are greater and more strongly associated to aspect ratio in males than in females might be indicating that in males the selective pressures affecting flight performance characteristics are more heterogeneous and/or stronger than in females among the studied species.

“…The Pearson correlation coefficient was applied to reveal a set of interdependent characters. For this objective, the dataset of Procrustes Coordinates, describing the wing shape of Dolichopodidae species and obtained using geometric morphometrics methods (more detailed described in [22]) was used.

A comparative analysis of 30 species of the Dolichopodidae family in a phylogenetic context was conducted to examine interspecific variation in the legs morphometry. Five relative traits of legs from 12 and seven absolute traits from nine showed significant phylogenetic signal. A set of traits, such as relatively short hind tibia and relatively long fore and middle tibia and the first segments of the hind legs allowed to allocate Dolichopus species from the other ones. The projection of the phylogenetic tree of Dolichopus species into the morphospace allowed us to divide it into four individual areas: not closely related species, but species having similar modifications of males legs tended to cluster. This suggests that the legs morphometric traits should be mainly under pressure of sexual selection. It has also been revealed that the elongation of the first segment of hind tarsi in Dolichopus species is associated with the distal displacement of the insertion point of dm-m with M4 and the decrease of the length of R4+5 . The functional significance of these characters set is discussed.
