“…This trait is conspicuously divergent in repleta group, which are otherwise rather conservative in their external morphology (Vilela, 1983). Other sexual dimorphic traits are also variable among even closely related species (Andersson, 1994); however, they are often more conservative than male external genitalia (Kopp & True, 2002; Padró et al., 2019), in part because these traits are frequently subject to selection pressures not only related to sexual selection processes. Therefore, male genitalia constitutes an excellent model to understand key aspects of morphological divergence and speciational processes.…”

“…Previous evidence showed that the type of cactus used as host (prickly pears or columnar cacti) affects the aedeagal morphology in the D. buzzatii complex (Soto et al, 2007).

The Drosophila repleta group comprises more than one hundred species that inhabit several environments in the Neotropics and use different hosts as rearing and feeding resources. Rather homogeneous in their external morphology, they are generally distinguished by the male genitalia, seemingly their fastest evolving morphological trait, constituting an excellent model to study patterns of genital evolution in the context of a continental adaptive radiation. Although much is known about the evolution of animal genitalia at population level, surveys on macroevolutionary scale of this phenomenon are scarce. This study used a suite of phylogenetic comparative methods to elucidate the macroevolutionary patterns of genital evolution through deep time and large continental scales. Our results indicate that male genital size and some aspects of shape have been evolving by speciational evolution, probably due to the microevolutionary processes involved in species mate recognition. In contrast, several features of the aedeagus shape seemed to have evolved in a gradual fashion, with heterogeneous evolutionary phenotypic rates among clades. In general, the tempo of the evolution of aedeagus morphology was constant from the origin of the group until the Pliocene, when it accelerated in some clades that diversified mainly in this period. The incidence of novel ecological conditions in the tempo of aedeagus evolution and the relationship between species mate recognition and speciation in the Drosophila repleta group are discussed.

Sexually selected traits may also be subject to non‐sexual selection. If optimal trait values depend on environmental conditions, then “narrow sense” (i.e., non‐sexual) natural selection can lead to local adaptation, with fitness in a certain environment being highest among individuals selected under that environment. Such adaptation can, in turn, drive ecological speciation via sexual selection. To date, most research on the effect of narrow‐sense natural selection on sexually selected traits has focused on precopulatory measures like mating success. However, postcopulatory traits, such as sperm function, can also be under non‐sexual selection, and have the potential to contribute to population divergence between different environments. Here, we investigate the effects of narrow‐sense natural selection on male postcopulatory success in Drosophila melanogaster. We chose two extreme environments, low oxygen (10%, hypoxic) or high CO2 (5%, hypercapnic) to detect small effects. We measured the sperm defensive (P1) and offensive (P2) capabilities of selected and control males in the corresponding selection environment and under control conditions. Overall, selection under hypoxia decreased both P1 and P2, while selection under hypercapnia had no effect. Surprisingly, P1 for both selected and control males was higher under both ambient hypoxia and ambient hypercapnia, compared to control conditions, while P2 was lower under hypoxia. We found limited evidence for local adaptation: the positive environmental effect of hypoxia on P1 was greater in hypoxia‐selected males than in controls. We discuss the implications of our findings for the evolution of postcopulatory traits in response to non‐sexual and sexual selection.

“…The ‘lock‐and‐key’ hypothesis predicts relatively low intra‐specific phenotypic variation since it implies a strict fit between female and male genitalia (Mutanen, Kaitala & Mönkkönen, 2006; Sloan and Simmons, 2019), whereas high intra‐specific phenotypic variation tends to indicate sexual selection (Eberhard et al ., 1998; Eberhard et al ., 2009). The allometry, referring to different traits of the body showing different growth and development rates compared to the entire body (Pélabon et al ., 2014; Hallgrímsson et al ., 2019), can effectively reflect variation within the species (Rodríguez et al ., 2015b; Voje, 2016; Padró et al ., 2019). A positive allometry (slope > 1) means the trait is disproportionally large in larger individuals, whereas a negative allometry (slope < 1) indicates the trait is relatively constant compared with body size and large individuals have relatively small structures (Rodríguez & Eberhard, 2019).…”

Intra‐specific variation of non‐genitalic and genitalic traits in two euophryine jumping spider species

Intra‐specific variation pattern is informative to understanding the evolution of morphological traits, but has been rarely studied in jumping spiders. Here we investigate the intra‐specific variation of non‐genitalic and genitalic traits in two euophryine jumping spider species that show considerable difference in sexual dimorphism: Chapoda recondita (Peckham & Peckham, 1896) and Antillattus cambridgei (Bryant, 1943). The results show the pre‐copulatory sexually selected traits (e.g. male chelicerae) tend to have positive intra‐specific allometry, and thus may have evolved under strong directional selection. The genitalic traits and some non‐genitalic traits tend to show negative allometries. Unlike non‐genitalic traits, the genitalic traits usually have high size‐corrected intra‐specific variation (CV’). Factors that may account for the negative allometry and high size‐corrected intra‐specific variation in genitalic traits are discussed. Pre‐ and post‐copulatory sexual selection may coexist in species and whether there is a trade‐off between these two selection mechanisms remains to be investigated.
