Rove beetles (Staphylinidae) are a diverse insect group, especially in the Neotropical region. At the same time, this fauna remains significantly understudied. During our visits to museum collections, we encountered numerous specimens of undescribed species representing the Neotropical genus Neolindus Scheerpeltz, 1933 which was earlier thought to be rare. To address the knowledge gap in the genus, we studied the museum material that resulted in descriptions of 21 new species. Our work involves the redescription of the genus, descriptions of the new species, and an updated identification key to 39 previously described and new species. The newly described species are Neolindus bicornis Guzman, Tokareva & Żyła sp. nov., N. elegans Guzman, Tokareva & Żyła sp. nov., N. longithorax Guzman, Tokareva & Żyła sp. nov., N. luxipenis Guzman, Tokareva & Żyła sp. nov., N. maya Guzman, Tokareva & Żyła sp. nov., N. minutus Guzman, Tokareva & Żyła sp. nov., N. napo Guzman, Tokareva & Żyła sp. nov., N. niger Guzman, Tokareva & Żyła sp. nov., N. ornatus Guzman, Tokareva & Żyła sp. nov., N. parahermani Guzman, Tokareva & Żyła sp. nov., N. paraplectrus Guzman, Tokareva & Żyła sp. nov., N. parasinuatus Guzman, Tokareva & Żyła sp. nov., N. parautriensis Guzman, Tokareva & Żyła sp. nov., N. pseudosensillaris Guzman, Tokareva & Żyła sp. nov., N. sauron Guzman, Tokareva & Żyła sp. nov., N. sibyllae Guzman, Tokareva & Żyła sp. nov., N. triangularis Guzman, Tokareva & Żyła sp. nov., N. tropicalis Guzman, Tokareva & Żyła sp. nov., N. utriensis Guzman, Tokareva & Żyła sp. nov., N. volkeri Guzman, Tokareva & Żyła sp. nov., and N. yotokae Guzman, Tokareva & Żyła sp. nov. This research emphasises the importance of museum collections in advancing taxonomy and enriching biodiversity knowledge. With these contributions, the known number of species of Neolindus reaches 60, thereby enhancing data on the Neotropical rove beetles diversity. Additionally, we provide several new country records for the genus (Guyana, Mexico, Nicaragua, and Suriname), which widen its distribution, and new occurrence records for the described species of Neolindus, N. agilis Herman, 1991; N. apiculus Herman, 1991; N. basisinuatus Herman, 1991; N. campbelli Herman, 1991; N. cuneatus Herman, 1991; N. hermani Asenjo, 2011; N. irmleri Asenjo, 2011; N. lodhii Herman, 1991; N. procarinatus Herman, 1991; N. punctogularis Herman, 1991; and N. retusus Herman, 1991.
Four new species of the Australian genus of Eurybrachidae (Hemiptera, Fulgoromorpha) Olonia Stål, 1862 are described from northern Queensland: O. albomarginata sp. nov., O. aschei sp. nov., O. jackiei sp. nov. and O. lindae sp. nov. Host plants and natural history data are documented and additional new records provided for O. guillaumei Constant, 2018, O. hochae Constant, 2018, O. picea Kirkaldy, 1906, O. rubicunda (Walker, 1851) and O. soulierae Constant, 2018. Trophobiosis is recorded for the first time in the genus, between a female of O. hochae and ants of the genus Camponotus Mayr, 1861 (Hymenoptera, Formicidae), representing the second record of trophobiosis in Australian Eurybrachidae. The male terminalia of the new species are illustrated and photographs of collection and live specimens, distribution maps, biological data and an identification key are provided. The genus Olonia currently contains sixteen species.
In the present study, a revision of the phylogeny and taxonomy of the family Dorididae is carried out focusing on the genus Doris Linnaeus, 1758. The type species D. verrucosa Linnaeus, 1758 and a blueish and yellow morphotype of D. ocelligera collected in different localities in the Mediterranean Sea and the North-East Atlantic were sequenced, as well as D. bertheloti and the elusive D. marmorata for the first time. The genetic markers include the cytochrome c oxidase subunit I, 16S rRNA, and histone 3. The phylogenetic results suggest that the genus Doris is paraphyletic, and D. ocelligera morphotypes separate into two species, as confirmed with species delimitation tests. To complement the phylogenetic evidence with morphoanatomical data, the dissection of two specimens of each morphotype is conducted. Significant differences in morphological traits such as body shape, colouration patterns, and mantle tubercles come to light, together with anatomical differences in the relative shape and size of the radular teeth and reproductive structures. Considering the modern and old descriptions of D. ocelligera, it is finally concluded that the blueish morphotype belongs to D. ocelligera. In contrast, the yellow morphotype responds to the actual synonym Aldisa berghi (Vayssière, 1901), which is resurrected here as Doris berghi comb. rest. Considering the broad phylogeny of the family, some systematic notes at the genus level are here provided.
New World lampyrid taxonomy faces severe taxonomic impediments. Most species remain known from original taxonomic descriptions only, often insufficient for accurate identification. Therefore, the study of type specimens is critical to ensure proper identification. The Russian entomologist Viktor Ivanovich Motschulsky was one of the most important authors of firefly (Coleoptera: Lampyridae) taxonomy during the XIXth century, and his work is still relevant today. Part of his material, including the type specimens of several species, is deposited at the Zoological Institute of the Russian Academy of Sciences. Unlike their European, Asian, and Oceanian counterparts, the taxonomy of Neotropical fireflies is still in its infancy, partly due to largely outdated literature and difficulties in accessing type specimens. Here, we review the type specimens of 38 firefly species deposited at ZIN, 15 of which are holotypes and 7 are lectotypes. For each specimen, the name-bearing status, condition of preservation, as well as the associated label data are provided. Lectotypes are designated for the following species described by Motschulsky: Bicellonycha lividipennis, Ellychnia californica, Lychnuris klugii, Macrolampis longipennis, Pseudolychnuris suturalis, Telephoroides lineaticollis, Telephoroide occidentalis.
Over the last few decades, considerable attention has focused on small-scale studies of invasive plants and invaded systems. Unfortunately, small scale studies rarely provide comprehensive insight into the complexities of biological invasions at macroscales. Systematic and repeated monitoring of biological invasions at broad scales are rare. In this report, we highlight a unique invasive plant database from the national Forest Inventory and Analysis (FIA) program of the United States Forest Service. We demonstrate the importance and capability of this subcontinental-wide database by showcasing several critical macroscale invasion patterns that have emerged from its initial analysis: (1) large portion of the forests systems (39%) in the United States are impacted by invasive plants, (2) forests in the eastern United States harbor more invasive species than the western regions, (3) human land-use legacies at regional to national scalesb may drive large-scale invasion patterns. This accumulated dataset, which continues to grow in temporal richness with repeated measurements, will allow the understanding of invasion patterns and processes at multi-spatial and temporal scales. Such insights are not possible from smaller-scale studies, illustrating the benefit that can be gained by investing in the development of regional to continental-wide invasion monitoring programs elsewhere.
