Data from: Retrogressive moulting in khapra beetle, Trogoderma granarium (Coleoptera: Dermestidae)
<p><span class="Dummy">Insect larvae typically moult to grow, but here we investigate insect larvae that moult to shrink; that is, retrogressive moulting or retrogressive development. We demonstrate this phenomenon in the khapra beetle, </span><em><span class="fi">Trogoderma granarium</span></em><span class="Dummy"> Everts (Dermestidae), among the world's most invasive pests of stored grains and cereal products, and a quarantine pest of interest for many countries. Larvae survived a 3‐month period of starvation, moulting up to six times and reducing their body mass by about half, on average. When reprovisioned with food, most larvae resumed the normal trajectory of development and pupated within a month. Thus, retrogressive development is a mechanism that may favour species whose resources exhibit feast‐or‐famine dynamics. By enabling survival during periods of privation, retrogressive development contributes to the invasiveness of the khapra beetle by allowing them to persist for long periods in empty storage facilities or empty containers used for international grain shipments.</span></p>

Molecular phylogeny of Dermestidae (Coleoptera) reveals the polyphyletic nature of Trogoderma Latreille, and the taxonomic placement of the Khapra Beetle Trogoderma granarium Everts
<p>The hide, larder and carpet beetles (Coleoptera: Dermestidae) are a family of mainly scavenger beetles, with numerous species such as the khapra beetle (<em>Trogoderma</em> <em>granarium</em> Everts, 1898), the black carpet beetle (<em>Attagenus</em> <em>unicolor</em> (Brahm, 1791)) and the hide beetle (<em>Dermestes</em> <em>maculatus</em> De Geer, 1774) being widely recognised as serious economic pests of stored products and museum collections (Fig. 1). A stable classification and reliable identification of genera and species of these pests and their 1,700 relatives are of great relevance for trade restrictions, biosecurity, pest management, forensics and biodiversity surveys.</p> <p>In this study, we examined and sequenced mitochondrial genomes of 477 dermestid specimens, representing all subfamilies and 90% of the globally recognised tribes and subtribes. Our study provides the most comprehensive, taxonomically verified and vouchered resource of mitochondrial reference sequences linked to specimen images and occurrence records of pests and their relatives, enabling eDNA surveys, metabarcoding and molecular species identification. It also reconstructs the phylogeny of Dermestidae based on molecular and morphological data for the first time, thereby providing robust phylogenetic hypotheses for a stable classification system from family to genus-level.</p> <p>Accordingly, a revised classification of Dermestidae with formal nomenclatural changes is proposed, recognising six subfamilies: Orphilinae, Trinodinae, Trogoparvinae subfam. nov. (type genus <em>Trogoparvus</em> Háva, 2001), Dermestinae, Attageninae and Megatominae. Trinodinae is recovered towards the base of Dermestidae with three tribes: Trinodini (=Trinoparvini syn. nov.), Thylodriini and Trichelodini. Dermestinae is the only subfamily with adults lacking a median ocellus, and it includes the tribes Thorictini stat. nov. (that is downgraded from Thorictinae), Marioutini and Dermestini. The endemic Australian genus <em>Derbyana</em> Lawrence and Ślipiński, was recovered within Holarctic <em>Dermestes</em> Linnaeus. Attageninae is strongly supported and includes the monogeneric Adelaidiini and polygenic Attagenini. Former subgenera of <em>Attagenus</em> Latreille, i.e., <em>Lanorus</em> Mulsant and Rey (= Paranovelsis Casey syn. nov.), <em>Telopes</em> Redtenbacher, and <em>Aethriostoma</em> Motschulsky, are elevated to generic level. The largest clade, Megatominae, is confirmed as monophyletic and is divided into three tribes: Anthrenini, Ctesiini and Megatomini. Megatomini is divided into three subtribes: Megatomina, Orphinina subtribe nov. (type genus <em>Orphinus</em> Motschulsky) and Trogodermina. Within the economically important lineage Trogodermina, <em>Trogoderma</em> Latreille, is delimited to contain only Holarctic species including the Khapra beetle <em>T</em>. <em>granarium</em> Everts, while a Southern Hemisphere clade is here recognised as <em>Eurhopalus</em> Solier in Gay, 1849 (= <em>Anthrenocerus</em> Arrow, 1915; <em>Myrmeanthrenus</em> Armstrong, 1945; <em>Neoanthrenus</em> Armstrong, 1941; <em>Sodaliatoma</em> Háva, 2013; <em>Reesa</em> Beal, 1967 syn. nov.). A revised classification of the extant genera of Dermestidae is also provided.</p>
