“…The HiSSE (Beaulieu & O'Meara, 2016) and MuHiSSE (Nakov et al, 2019) allow a sophisticated test that acknowledges that additional unknown factors might be contributing to species diversification. We propose body pigmentation, dimorphism, territoriality, genital differentiation as other possible factors worth testing in future species diversification studies (Cordero-Rivera & Rivas-Torres, 2019;Grether, 2019;Outomuro et al, 2013;Santos & Machado, 2016).…”

1. In dragonflies, species richness shows a marked variation between lineages. Species diversification in this lineage has been linked with habitat variation, but the role of other factors, such as wing pigmentation, arguably one of the most conspicuous traits in dragonflies, have not yet been explored.2. In this study, using novel methodology that takes into account state-dependent speciation, extinction models, and ancestral reconstruction, we investigate the role of wing pigmentation (present/absent) in conjunction with habitat variation (lentic/ lotic), to unveil the drivers of species diversification in dragonflies.3. We found that wing pigmentation is associated with a marginal increase in diversification compared to unpigmented lineages. Inhabiting a lentic habitat is associated with higher diversification rates. When considering both factors in a single model, lentic environments are associated with higher diversification compared to lotic habitats regardless of pigmentation status. In contrast with results across the whole tree, in lotic environments, wing pigmentation is associated with marginally higher diversification rates compared to non-pigmented species. Ancestral state reconstruction revealed that the last common ancestor of dragonflies was most likely non-pigmented and lived in lotic habitats. 4. Our study provides evidence that wing pigmentation in conjunction with habitat has an important influence on dragonflies species diversification, with habitat being a better differentiator than wing pigmentation.

“…The big question that remains is why would females prefer to endure physical stress rather than submit to convenience polyandry (Cordero and Andrés 2002). The accumulation of evidence of behavior to avoid sex in odonates (Cordero‐Rivera and Rivas‐Torres 2019) highlights the costs of multiple matings for females, which could involve both apparent and cryptic costs that merit further investigation (copulatory wounding, sexually transmissible disease, or seminal toxins) (Johnstone and Keller 2000, Reinhardt et al. 2015).…”

“…Sexual conflict occurs widely in various animal species [21][22][23][24] and is considered a significant driver of male-female coevolution in insects, with profound implications for the evolution of reproductive isolation and speciation [22,23,25]. Gerromorphans constitute a classical model for the study of sexual selection and sexual conflict [26][27][28][29][30].…”

Fossilized mating insects are irreplaceable material for comprehending the evolution of the mating behaviours and life-history traits in the deep-time record of insects as well as the potential sexual conflict. However, cases of mating pairs are particularly rare in fossil insects, especially aquatic or semi-aquatic species. Here, we report the first fossil record of a group of water striders in copulation (including three pairs and a single adult male) based on fossils from the mid-Cretaceous of northern Myanmar. The new taxon, Burmogerris gen. nov., likely represents one of the oldest cases of insects related to the marine environment, such as billabongs formed by the tides. It exhibits conspicuous dimorphism associated with sexual conflict: the male is equipped with a specialized protibial comb as a grasping apparatus, likely representing an adaptation to overcome female resistance during struggles. The paired Burmogerris show smaller males riding on the backs of the females, seemingly recording a scene of copulatory struggles between the sexes. Our discovery reveals a mating system dominated by males and sheds light on the potential sexual conflicts of Burmogerris in the Cretaceous. It indicates the mating behaviour remained stable over long-term geological time in these water-walking insects.
