“…They are incapable of swift running and their flight is slow and reluctant. As an alternative to effective escape mechanisms they achieve protection through poisonous and repellent substances (Moore & Brown 1981), and they are aposematically coloured (Cantharidae and Lycidae; Linsley et al 1961) or use luminescence as an aposematic signal (Lampyridae and Phengodidae;De Cock & Matthysen 2003). Most neotenic females and their larvae live cryptically and are also cryptically coloured.…”

Neoteny, the maintenance of larval features in sexually mature adults, is a radical way of generating evolutionary novelty through shifts in relative timing of developmental programmes. While controlled by the environment in facultative neotenics, retention of larval features is obligatory in many species of Lycidae (net-winged beetles). They are studied here as an example of how developmental shifts and ecology interact to produce macroevolutionary impacts. We conducted a phylogenetic analysis of Lycidae based on DNA sequences from nuclear (18S and 28S rRNA) and mitochondrial (rrnL, cox1, cob and nad5) genes from a representative set of lineages (73 species), including 17 neotenic taxa. Major changes of basal relationships compared with those implied in the current classification generally supported three independent origins of neotenics in Lycidae. The southeast Asian Lyropaeinae and Ateliinae were in basal positions indicating evolutionary antiquity, also confirmed by molecular clock estimates, unlike the neotropical leptolycines nested within Calopterini and presumably much younger. neotenics exhibit typical K-selected traits including slow development, large body size, high investment in offspring and low dispersal. This correlated with low species richness and restricted ranges of neotenic lineages compared with their sisters. Yet, these factors did not impede the evolutionary persistence of affected lineages, even without reversals to fully metamorphosed forms, contradicting earlier suggestions of recent evolution from dispersive non-neotenics.

“…Charge transfer complexes between polyacetylenes and unidentified partners have been suggested as a sequestration mechanism [501]. Coupled with strong methoxyalkylpyrazine odorants and bitter 3-phenylpropanamide and 1-methyl-2-quinoline, 1,8-cineole and polyacetylenes are thought to provide a 3 rd line of antifeedant defense for the beetle Metriorrhynchus rhipidius [502]. The interaction of plants with insects, whether by herbivores, pollinators, or co-inhabitants, should be considered reciprocally in terms of evolution.…”

Polyacetylenic natural products are a substantial class of often unstable compounds containing a unique carbon-carbon triple bond functionality, that are intriguing for their wide variety of biochemical and ecological functions, economic potential, and surprising mode of biosynthesis. Isotopic tracer experiments between 1960 and 1990 demonstrated that the majority of these compounds are derived from fatty acid and polyketide precursors. During the past decade, research into the metabolism of polyacetylenes has swiftly advanced, driven by the cloning of the first genes responsible for polyacetylene biosynthesis in plants, moss, fungi, and actinomycetes, and the initial characterization of the gene products.The current state of knowledge of the biochemistry and molecular genetics of polyacetylenic secondary metabolic pathways will be presented together with an up-to-date survey of new terrestrial and marine natural products, their known biological activities, and a discussion of their likely metabolic origins.

“…Metriorrhynchinae are often involved in Mullerian mimicry complexes, Lawrence & Britton (1991) mentioned those from Australia. Moore & Brown (1981) studied the antifeedants in the body of Porrostoma rhippidium (W. M. Leay, 1827).…”

Abstract. The subfamily Metriorrhynchinae is the most species-rich clade of Lycidae (Coleoptera). A recent proposal suggests that the Erotinae is a sister group of the Metriorrhynchinae. Within the Metriorrhynchinae, evidence is presented for the monophyly of the Conderini and Metriorrhynchini and their sister group position. The Trichalina, Hemiconderina and Metriorrhynchina form the tribe Metriorrhynchini. The relationships between the basal lineages of this group are poorly understood. Several clades are distin guished within the Metriorrhynchina, but there is only weak evidence supporting a relationships between them. The distribution of individual clades is discussed.
