“…The taxonomic diversity of Yponomeutoidea has been little explored in the Neotropics in recent years (Cepeda 2016;Vargas 2018;Moreira et al 2019). Hsu & Powell (2004) suggested that a great part of the diversity of the Heliodinidae remains unknown in Central and South America.…”

The adult stage of Helioandesia tarregai gen. et sp. nov. (Lepidoptera: Yponomeutoidea: Heliodinidae) is described and illustrated from the arid western slopes of the Andes of northern Chile. The larvae of H. tarregai gen. et sp. nov. feed as leaf skeletonizers on Mirabilis acuta (Reiche) Heimerl (Nyctaginaceae). The mostly gray forewing of H. tarregai gen. et sp. nov., ornamented with strongly bulging metallic spots, resembles that of the representatives of the mainly Nearctic Lithariapteryx Chambers, 1876. However, the latter lacks CuP in the forewing, has a single bristle in the female frenulum, and lacks a well-developed cornutus. Helioandesia gen. nov. clustered as sister to Neoheliodines Hsu, 2004 in a cladistic analysis, although no synapomorphies were found for this cluster, while Lithariapteryx was sister to Helioandesia gen. nov. + Neoheliodines based on two synapomorphies. The genetic distance between a DNA barcode sequence of H. tarregai gen. et sp. nov. and representatives of other genera of Heliodinidae Heinemann, 1877 was 9.0–12.5% (K2P), and a maximum likelihood analysis based on this molecular marker confirmed the placement of H. tarregai gen. et sp. nov. as a member of this micromoth family. This contribution represents the first confirmed record of Heliodinidae for Chile.

“…Recent contributions suggest that the taxonomic diversity and natural history of Yponomeutoidea remain underexplored in the Neotropics (e.g. Becker 2009 , Becker 2013 , Moreira et al 2019 ). In the present study, a single field trip was enough to discover a previously-unknown species and to unveil a novel host plant association for the Neotropical fauna of Ypsolopha .…”

The largest number of species of the widespread and highly diverse micromoth genus Ypsolopha Latreille, 1796 (Lepidoptera, Yponomeutoidea, Ypsolophidae) is known from the Northern Hemisphere. Only seven species have been described from the Neotropical Region, two of which occur in Chile. The adult stage of Ypsolopha chicoi sp. n. from the arid highlands of the western slopes of the Andes of northern Chile is described and illustrated. Its larvae feed on the native shrub Muehlenbeckia fruticulosa (Walp.) Standl. (Polygonaceae). The morphology of the genitalia of Y. chicoi sp. n. resembles that of the only congeneric known to occur in the same geographic area, Y. moltenii Vargas, 2018, whose larvae feed on Adesmia verrucosa Meyen (Fabaceae). Besides using different host plants, the two species can be accurately separated, based on morphological differences in female and male genitalia.

“…Although this basket web is unique across spider webs, some insects also build free-standing silken structures. For instance, the moths of the family Urodidae build cage-like, protective cocoons 34 – 36 , which seem to possess a similar dimensional stability compared with the webs of S. formivorus . Free-standing, single silk threads were further observed with lacewings, forming egg stalks made of proteins with a cross- β structure 37 .…”

Our understanding of the extraordinary mechanical and physico-chemical properties of spider silk is largely confined to the fibers produced by orb-weaving spiders, despite the diversity of foraging webs that occur across numerous spider families. Crab spiders (Thomisidae) are described as ambush predators that do not build webs, but nevertheless use silk for draglines, egg cases and assembling leaf-nests. A little-known exception is the Australian thomisid Saccodomus formivorus, which constructs a basket-like silk web of extraordinary dimensional stability and structural integrity that facilitates the capture of its ant prey. We examined the physical and chemical properties of this unusual web and revealed that the web threads comprise microfibers that are embedded within a biopolymeric matrix containing additionally longitudinally-oriented submicron fibers. We showed that the micro- and submicron fibers differ in their chemical composition and that the web threads show a remarkable lateral resilience compared with that of the major ampullate silk of a well-investigated orb weaver. Our novel analyses of these unusual web and silk characteristics highlight how investigations of non-model species can broaden our understanding of silks and the evolution of foraging webs.
