Abstract. Pyraloidea, one of the largest superfamilies of Lepidoptera, comprise more than 15 684 described species worldwide, including important pests, biological control agents and experimental models. Understanding of pyraloid phylogeny, the basis for a predictive classification, is currently provisional. We present the most detailed molecular estimate of relationships to date across the subfamilies of Pyraloidea, and assess its concordance with previous morphology-based hypotheses. We sequenced up to five nuclear genes, totalling 6633 bp, in each of 42 pyraloids spanning both families and 18 of the 21 subfamilies, plus up to 14 additional genes, for a total of 14 826 bp, in 21 of those pyraloids plus all 24 outgroups. Maximum likelihood analyses yield trees that, within Pyraloidea, differ little among datasets and character treatments and are strongly supported at all levels of divergence (83% of nodes with bootstrap ≥80%). Subfamily relationships within Pyralidae, all very strongly supported (>90% bootstrap), differ only slightly from a previous morphological analysis, and can be summarized as Galleriinae + Chrysauginae (Phycitinae (Pyralinae + Epipaschiinae)). The main remaining uncertainty involves Chrysauginae, of which the poorly studied Australian genera may constitute the basal elements of Galleriinae + Chrysauginae or even of Pyralidae. In Crambidae the molecular phylogeny is also strongly supported, but conflicts with most previous hypotheses. Among the newly proposed groupings are a 'wet-habitat clade' comprising Acentropinae + Schoenobiinae + Midilinae, and a provisional 'mustard oil clade' containing Glaphyriinae, Evergestinae and Noordinae, in which the majority of described larvae feed on Brassicales. Within this clade a previous synonymy of Dichogaminae with the Glaphyriinae is supported. Evergestinae syn. n. and Noordinae syn. n. are here newly synonymized with Glaphyriinae, which appear to be paraphyletic with respect to both. Pyraustinae and Spilomelinae as Re-use sampled here are each monophyletic but form a sister group pair. Wurthiinae n. syn., comprising the single genus Niphopyralis Hampson, which lives in ant nests, are closely related to, apparently subordinate within, and here newly synonymized with, Spilomelinae syn. n. IntroductionThe Pyraloidea, comprising the families Pyralidae and Crambidae, are one of the mega-diverse superfamilies of Lepidoptera, trailing only Gelechioidea and Papilionoidea outside the Macroheterocera sensu van Nieukerken et al. (2011). The 15 500 + described species (van Nieukerken et al., 2011) are distributed worldwide; many more species are undescribed, especially in the tropics. Pyraloidea include numerous major pests of crops, stored foodstuffs, forests and ornamental plants, as well as biological control agents used successfully against invasive plants (e.g. Zhang, 1994;Center et al., 2002). They are among the most ecologically diverse lepidopteran superfamilies: in addition to feeding on most major groups of plants, pyraloid larvae collectively expl...

Pollination of several angiosperms is based on deceit. In such systems, the flowers advertise a reward that ultimately is not provided. We report on a previously unknown pollination/mimicry system discovered in deceptive Aristolochia rotunda (Aristolochiaceae).Pollinators were collected in the natural habitat and identified. Flower scent and the volatiles of insects (models) potentially mimicked were analyzed by chemical analytical techniques. Electrophysiological and behavioral tests on the pollinators identified the components that mediate the plant–pollinator interaction and revealed the model of the mimicry system.The main pollinators of A. rotunda were female Chloropidae. They are food thieves that feed on secretions of true bugs (Miridae) while these are eaten by arthropod predators. Freshly killed mirids and Aristolochia flowers released the same scent components that chloropids use to find their food sources. Aristolochia exploits these components to deceive their chloropid pollinators.Aristolochia and other trap flowers were believed to lure saprophilous flies and mimic brood sites of pollinators. We demonstrate for A. rotunda, and hypothesize for other deceptive angiosperms, the evolution of a different, kleptomyiophilous pollination strategy. It involves scent mimicry and the exploitation of kleptoparasitic flies as pollinators. Our findings suggest a reconsideration of plants assumed to show sapromyiophilous pollination.

The larvae of the Old World genera Leucinodes Guenée, 1854 and Sceliodes Guenée, 1854 are internal feeders in the fruits of Solanaceae, causing economic damage to cultivated plants like Solanum melongena and Solanum aethiopicum. In sub-Saharan Africa five nominal species of Leucinodes and one of Sceliodes occur. One of these species, the eggplant fruit and shoot borer Leucinodes orbonalis Guenée, 1854, is regarded as regularly intercepted from Africa and Asia in Europe, North and South America and is therefore a quarantine pest on these continents. We investigate the taxonomy of African Leucinodes and Sceliodes based on morphological characters in wing pattern, genitalia and larvae, as well as mitochondrial DNA, providing these data for identification of all life stages. The results suggest that both genera are congeneric, with Sceliodes syn. n. established as junior subjective synonym of Leucinodes. Leucinodes orbonalis is described from Asia and none of the samples investigated from Africa belong to this species. Instead, sub-Saharan Africa harbours a complex of eight endemic Leucinodes species. Among the former nominal species of Leucinodes (and Sceliodes) from Africa, only Leucinodes laisalis (Walker, 1859), comb. n. (Sceliodes) is confirmed, with Leucinodes translucidalis Gaede, 1917, syn. n. as a junior subjective synonym. The other African Leucinodes species were unknown to science and are described as new: Leucinodes africensis sp. n., Leucinodes ethiopica sp. n., Leucinodes kenyensis sp. n., Leucinodes malawiensis sp. n., Leucinodes pseudorbonalis sp. n., Leucinodes rimavallis sp. n. and Leucinodes ugandensis sp. n. An identification key based on male genitalia is provided for the African Leucinodes species. Most imports of Leucinodes specimens from Africa into Europe refer to Leucinodes africensis, which has been frequently imported with fruits during the last 50 years. In contrast, Leucinodes laisalis has been much less frequently recorded, and Leucinodes pseudorbonalis as well as Leucinodes rimavallis only very recently in fruit imports from Uganda. Accordingly, interceptions of Leucinodes from Africa into other continents will need to be re-investigated for their species identity and will likely require, at least in parts, revisions of the quarantine regulations. The following African taxa are excluded from Leucinodes: Hyperanalyta Strand, 1918, syn. rev. as revised synonym of Analyta Lederer, 1863; Analyta apicalis (Hampson, 1896), comb. n. (Leucinodes); Lygropia aureomarginalis (Gaede, 1916), comb. n. (Leucinodes); Syllepte hemichionalis Mabille, 1900, comb. rev., Syllepte hemichionalis idalis Viette, 1958, comb. rev. and Syllepte vagans (Tutt, 1890), comb. n. (Aphytoceros). Deanolis iriocapna (Meyrick, 1938), comb. n. from Indonesia is originally described and misplaced in Sceliodes, and Leucinodes cordalis (Doubleday, 1843), comb. n. (Margaritia) from New Zealand, Leucinodes raondry (Viette, 1981), comb. n. (Daraba) from Madagascar as well as Leucinodes grisealis (Kenrick, 1912), comb. n. (Scelio...

Crambidae is a group of moths with more than 10,000 species occurring worldwide that evolved diverse morphological and ecological habits. They can be best recognized by morphological characters of the adult tympanal organ and larval chaetotaxy. We present the first molecular phylogeny of Crambidae including all subfamilies and most tribes. We use available molecular data from two previous studies, and published transcriptomes and genomes, compiling ten genes totalling 11,247 bp. Up to eight genes are sequenced for thirty‐nine additional taxa, with Cathariinae, Cybalomiinae and Linostinae sampled for the first time. Maximum‐likelihood and Bayesian analyses recover topologies mostly agreeing with those of previous studies, with several groupings showing better support. Cathariinae syn. n. and Cybalomiinae syn. n. are recovered as ingroup of Glaphyriinae and are consequently synonymized with the latter. Linostinae are either sister to Glaphyriinae or sister to the ‘CAMMSS clade’. Lathrotelinae are recovered monophyletic and as sister to Musotiminae in the Bayesian analysis. Hoploscopinae stat. n. are recovered as sister to ((Crambinae + Erupinae stat. n.) + (Scopariinae + Heliothelinae s. str.)). Evolution of host‐plant preferences is discussed.
