Reconstitution of some tribes and genera of Lagriinae (Coleoptera, Tenebrionidae).

The tribes Goniaderini Lacordaire, 1859 and Lupropini Lesne, 1926 within the tenebrionid subfamily Lagriinae Latreille, 1825 have previously been shown to be non-monophyletic by molecular phylogenetic analyses. The tribes and constituent genera are here reviewed and redefined morphologically. As part of tribal redefinitions, we establish PrateiniNew Tribe with type genus Prateus LeConte, 1862. We reestablish the subtribe Phobeliina Ardoin, 1961 Revised Status, which is transferred from Goniaderini and placed as a subtribe of Lagriini Latreille, 1825 where it is comprised of Phobelius Blanchard, 1842, and Rhosaces Champion, 1889 (previously in Lagriini: Statirina Blanchard, 1845). The fossil tribe Archaeolupropini Nabozhenko, Perkovsky, & Nazarenko, 2023 is transferred from Lagriinae to Tetratomidae: Tetratominae Billberg, 1820. Keys to extant tribes and subtribes of Lagriinae and genera of Goniaderini, Lupropini, and Prateini are provided. Generic and species-level changes from this work are as follows: Prateini is comprised of the following 15 genera: Antennoluprops Schawaller, 2007, Ardoiniellus Schawaller, 2013, Bolitrium Gebien, 1914, Enicmosoma Gebien, 1922, Indenicmosoma Ardoin, 1964, Iscanus Fauvel, 1904, Kuschelus Kaszab, 1982, Lorelopsis Champion, 1896, Mesotretis Bates, 1872, Microcalcar Pic, 1925, Micropedinus Lewis, 1894, Paratenetus Spinola, 1845, Prateus, Terametus Motschulsky, 1869, and Tithassa Pascoe, 1860.

Lorelopsispilosa Champion, 1896 becomes a Restored Combination. In Goniaderini, Aemymone Bates, 1868 Revised Status and Opatresthes Gebien, 1928 Revised Status, which were recently considered as subgenera of Goniadera Perty, 1832, are restored as valid genera based on new character analysis resulting in the following New Combinations: Aemymonehansfranzi (Ferrer & Delatour, 2007), A.simplex (Fairmaire, 1889), A.striatipennis (Pic, 1934) and Restored Combinations: Aemymonecariosa (Bates, 1868), A.crenata Champion, 1893, and A.semirufa Pic, 1917. Gamaxus Bates, 1868 is Returned to Synonymy with Phymatestes Pascoe, 1866, and the type species Gamaxushauxwelli Bates, 1868 is placed as a New Synonym of Phymatestesbrevicornis (Lacordaire, 1859).

Dominican amber net-winged beetles suggest stable paleoenvironment as a driver for conserved morphology in a paedomorphic lineage.

Paedomorphosis is a heterochronic syndrome in which adult individuals display features of their immature forms. In beetles, this phenomenon occurs widely in the superfamily Elateroidea, including the net-winged beetles (Lycidae), and, due to the usual flightlessness of paedomorphic females, it is hypothesized to cause speciation rates higher than in non-paedomorphic lineages. However, some fossils of paedomorphic lycids do not support this with palaeobiological data. Discovery of new Lycidae fossils attributed to the West Indian extant paedomorphic genus Cessator Kazantsev in the Dominican amber also suggests morphological stasis within this genus in the Greater Antilles. We describe Cessator anachronicus Ferreira and Ivie, sp. nov. based on adult males, as well as the first ever recorded fossil net-winged beetle larva of the same genus. We propose that the relatively young age of the studied fossils combined with the stable conditions in the forest floor of the Greater Antilles through the last tens of million years could explain the exceptionally conserved morphology in the net-winged beetles affected by the paedomorphic syndrome.

Unlocking the mystery of the mid-Cretaceous Mysteriomorphidae (Coleoptera: Elateroidea) and modalities in transiting from gymnosperms to angiosperms.

The monospecific family Mysteriomorphidae was recently described based on two fossil specimens from the Late Cretaceous Kachin amber of northern Myanmar. The family was placed in Elateriformia incertae sedis without a clear list of characters that define it either in Elateroidea or in Byrrhoidea. We report here four additional adult specimens of the same lineage, one of which was described using a successful reconstruction from a CT-scan analysis to better observe some characters. The new specimens enabled us to considerably improve the diagnosis of Mysteriomorphidae. The family is definitively placed in Elateroidea, and we hypothesize its close relationship with Elateridae. Similarly, there are other fossil families of beetles that are exclusively described from Cretaceous ambers. These lineages may have been evolutionarily replaced by the ecological revolution launched by angiosperms that introduced new co-associations with taxa. These data indicate a macroevolutionary pattern of replacement that could be extended to other insect groups.

A revision of Lycinella Gorham, 1884 with the description of six new species (Coleoptera, Lycidae, Calopterini).

The Neotropical genus Lycinella Gorham, 1884 is revised. Lycinellaopaca Gorham, 1884 and Lycinellaparvula Gorham, 1884 are redescribed and illustrated. Six new species are described for the genus: Lycinellaadamantis sp. n., L.hansoni sp. n., L.milleri sp. n., L.cidaoi sp. n., L.marshalli sp. n. and L.pugliesae sp. n.. Lycinellahumeralis Pic, 1933 is moved to Ceratoprionhumerale (Pic, 1933), comb. n. A key to the species of Lycinella, illustrations and a distribution map is provided.

Review of the West Indian genus Monotalla Bechyné (Coleoptera, Chrysomelidae, Galerucinae, Alticini) with description of five new species.

The West Indian genus Monotalla Bechyné is reviewed, redescribed and illustrated. Five new species are added: Monotalladominica sp. n. (Dominica); Monotallalecticofolia sp. n. (St. Lucia); Monotallamaierae sp. n. (St. Lucia); Monotallaobrienorum sp. n. (Grenada); and Monotallaviridis sp. n. (St. Lucia). A key to Monotalla species is provided.

DNA barcoding to improve the species-level management of wireworms (Coleoptera: Elateridae).

Economically important species of wireworms (Coleoptera: Elateridae) were successfully associated with adults using cytochrome oxidase I (COI) barcoding, proving the usefulness of this technique to associate life stages in taxonomically difficult pest groups. Previously unrecognized and morphologically difficult, even indistinguishable, pest larvae were shown to be identifiable using this technique. This is a critical step toward discovering effective species-based integrated pest management strategies for this resurgent pest group following the loss of Lindane seed treatments. Three new adult-larval associations were discovered for Hadromorphus callidus (Brown), Hemicrepidius carbonatus (LeConte) and Metanomus insidiosus (LeConte). Hypnoidus bicolor (Eschscholtz) was shown to comprise multiple divergent lineages at a level usually considered different species, indicating that the population structure of some pest species requires more investigation. The status of the prairie grain wireworm, Selatosomus destructor (Brown), as a full species or as a subspecies of Selatosomus aeripennis (Kirby) is called into question.

Effects of volcanic ash on the forest canopy insects of Montserrat, West Indies.

The impact of ash deposition levels on canopy arthropods was studied on the West Indian island of Montserrat, the site of an ongoing volcanic eruption since 1995. Many of the island's natural habitats have been buried by volcanic debris, and remaining forests regularly receive volcanic ash deposition. To test the effect of ash on canopy arthropods, four study sites were sampled over a 15-mo period. Arthropod samples were obtained using canopy fogging, and ash samples were taken from leaf surfaces. Volcanic ash has had a significant negative impact on canopy arthropod populations, but the decline is not shared equally by all taxa present, and total population variation is within the variance attributed to other aboitic and biotic factors. The affected populations do not differ greatly from those of the neighboring island of St. Kitts, which has not been subject to recent volcanic activity. This indicates that observed effects on Montserrat's arthropod fauna have a short-term acute response to recent ash deposition rather than a chronic depression caused by repeated exposure to ash over the last decade.

Field-based evaluation of biopesticide impacts on native biodiversity: malagasy coleoptera and anti-locust entomopathogenic fungi.

A community of 225 species of Coleoptera was used as a surrogate to evaluate nontarget effects of entomopathogenic fungi under development as biopesticides for use against the Malagasy migratory locust Locusta migratoria capito Saussure (Orthoptera: Acrididae). Evaluation of a standard chemical treatment of fenitrothion + esfenvalerate, two indigenous isolates of Metarhiziumflavoviride Gams & Roszsypol (SP3 and SP9), and an indigenous isolate of Beauveria bassiana (Balsamo) Vuillemin (SP16) against an untreated control in a replicated field trial in southern Madagascar showed that one of the isolates of M. flavoviride (SP3) and fenitrothion + esfenvalerate had distinct effects on nontarget beetle communities that were similar to each other. The other two isolates had no detectable effects compared with the untreated control. Based on an evaluation of the species affected, the similar effects of SP3 and the chemical pesticide are hypothesized to be the result of a perturbation of predator-prey relationships, with a distinct tendency to be manifested via predators. The data indicate that use of SP9 and SP16 would have minimal detrimental effects on the biodiversity of nontarget beetles, but that SP3 needs further testing.
