Fans enable water strider adaptation Genomes of closely related organisms are similar but contain variations that different phenotypes and lifestyles. The origin evolutionary innovations, such as insect wings bird feathers, poses a challenge to biology because the de novo emergence complex traits cannot easily be explained by natural selection. Water-walking Rhagovelia insects evolved propelling fan on middle leg is associated with life fast-flowing streams. Santos et al. discovered geisha...
The fauna of semiaquatic bugs (Insecta: Hemiptera: Heteroptera: Gerromorpha) from Panama has been explored mainly between the end 19th century and first half 20th century, with few reports since then, whereas that Colombia intensively studied in last decade. Here, we describe Rhagovelia joceliae Rodrigues & Moreira, sp. nov. (Veliidae: Rhagoveliinae), Panama. Additionally, new records these countries are presented for Mesovelia mulsanti White, 1879, Mes. zeteki Harris Drake, 1941...
A hallmark of eusociality in ants is the reproductive division labor between queens and workers. Yet, nothing known about molecular mechanisms underlying reproduction this group. We therefore compared developmental genetic capacity workers to reproduce several eusocially advanced species from two largest subfamilies ants, Myrmicinae Formicinae. In flies, asymmetric localization maternally encoded determinants (mRNAs proteins) during oogenesis establishes oocyte polarity subsequently ensures...
Sexual conflict is thought to be a potent force driving the evolution of sexually dimorphic traits. In water strider Rheumatobates rileyi, we show that elaborated traits on male antennae function grasp resistant females during premating struggles. Using RNA interference, uncovered novel roles gene distal-less (dll) in generating these male-specific Furthermore, graded reduction grasping resulted mating success males, thus demonstrating both selection for elaboration and role dll their...
The reproductive division of labour is a key feature eusociality in ants, where queen and worker castes show dramatic differences the development their organs. To understand developmental genetic basis underlying this labour, we performed molecular analysis ovary function germ cell queens workers. We that processes ovarian have been highly conserved relative to fruitfly Drosophila melanogaster. also identify specific steps during oogenesis embryogenesis which evolutionarily modified These...
The establishment of the germline is a critical, yet surprisingly evolutionarily labile, event in development sexually reproducing animals. In fly Drosophila, germ cells acquire their fate early during through inheritance plasm, specialized maternal cytoplasm localized at posterior pole oocyte. gene oskar (osk) both necessary and sufficient for assembling this substance. Both plasm are evolutionary novelties within insects, as specified by zygotic induction basally branching osk has until...
Having conquered water surfaces worldwide, the semi-aquatic bugs occupy ponds, streams, lakes, mangroves, and even open oceans. The diversity of this group has inspired a range scientific studies from ecology evolution to developmental genetics hydrodynamics fluid locomotion. However, lack representative strider genome hinders our ability more thoroughly investigate molecular mechanisms underlying processes adaptation diversification within group. Here we report sequencing manual annotation...

Water striders, a group of semi-aquatic bugs adapted to life on the water surface, have evolved mid-legs (L2) that are long relative their hind-legs (L3). This novel appendage ground plan is derived feature among insects, where L2 function as oars and L3 rudders. The Hox gene Ultrabithorax (Ubx) known increase size in variety insects. Using expression RNAi analysis, we discovered Ubx expressed both L3, but functions elongate shorten strider Gerris buenoi. Therefore, within hemimetabolous has...
Growth control scales morphological attributes and, therefore, provides a critical contribution to the evolution of adaptive traits. Yet, genetic mechanisms underlying growth in context specific ecological adaptations are poorly understood. In water striders, adaptation locomotion on surface is associated with allometric and functional changes thoracic appendages, such that T2-legs, used as propelling oars, longer than T3-legs, steering rudders. The Hox gene Ubx establishes this derived...
Abstract Key innovations enable access to new adaptive zones and are often linked increased species diversification. As such, have attracted much attention, yet their concrete consequences on the subsequent evolutionary trajectory diversification of bearing lineages remain unclear. Water striders relatives (Hemiptera: Heteroptera: Gerromorpha) represent a monophyletic lineage insects that transitioned live water–air interface diversified occupy ponds, puddles, streams, mangroves even oceans....
Abstract How novel genetic interactions evolve, under what selective pressures, and how they shape adaptive traits is often unknown. Here we uncover behavioural developmental mechanisms that enable water striders to survive attacks by bottom-striking predators. Long midlegs, critical for antipredator strategy, are shaped through a lineage-specific interaction between the Hox protein Ultrabithorax (Ubx) new target gene called gilt . The differences in leg morphologies established modulation...
Naturalists have been fascinated for centuries by animal colors and color patterns. While widely studied at the adult stage, we know little about patterns in embryo. Here, study a trait consisting of coloration that is specific to embryo absent from postembryonic stages water striders (Gerromorpha). By combining developmental genetics with chemical phylogenetic analyses across broad sample species, uncovered mechanisms underlying emergence diversification embryonic this group insects. We...
