   Abstract The Miltogramminae (Diptera: Sarcophagidae) includes ~600 species across >40 genera, which constitute ~20% of global Sarcophagidae. While molecular phylogenetic hypotheses have been produced for this group, critical problems persist, including the presence of paraphyletic genera, uncertain relationships between genera, a bias of sampling towards Palaearctic taxa, and low support for many branches. The present study remedies these issues through the application of Anchored Hybrid Enrichment (AHE) to a sample including ~60% of the currently recognised genera (16% of known species) representing all biogeographic regions except the Neotropical. An alignment of 1,281 concatenated loci was analysed with maximum likelihood (RAxML, IQ‐TREE), Bayesian inference (ExaBayes) and coalescent‐based approaches (ASTRAL, SVDquartets), which resulted in highly supported and concordant topologies, providing unprecedented insight into the relationships of this subfamily of flesh flies, allowing a major update to miltogrammine classification. The AHE phylogenetic hypothesis supports the monophyly of a large proportion of genera. The monophyly ofMetopiaMeigen is restored by synonymy withAenigmetopiaMalloch,syn.n.To achieve monophyly ofMiltogrammaMeigen, eight species are transferred fromPterellaRobineau‐Desvoidy. The genusPterellais shown to be paraphyletic in its current circumscription, and to restore generic monophylyPterellais restricted to contain onlyPt. grisea(Meigen).ErioproctaEnderlein,stat.rev., is resurrected. The genusSenotainiaMacquart is reconstructed as paraphyletic. The monotypic genusMetopodiaBrauer & Bergenstamm is synonymised withTaxigrammaMacquart,syn.n.In light of our phylogenetic hypotheses, a new Miltogramminae tribal classification is proposed, composed of six tribes.

2. A new firefly genus from South America, with seven new species, a new combination, and notes on the phylogeny of Lampyrinae: Lucidotini (Coleoptera: Lampyridae)

   BackgroundLucidotini is a diverse tribe of lampyrine fireflies present throughout the New World, Europe, and Asia. Most of the over 30 genera have overlapping diagnoses, largely due to a lack of revisionary and phylogenetic studies. Widespread convergence in sensory morphology, traditionally used in genus-level diagnoses, further compounds the taxonomic issues surrounding the Lucidotini. Recent work has cast light on the value of terminalia and genitalic traits for Lucidotini taxonomy and called for a more thorough screening of morphological characters. Of special interest are basal outgrowths of the phallus (i.e., ventrobasal processes)—currently only known inAlychnusKirsch andPhotinusLaporte–that can be quite informative at the species level, but its variation within Lucidotini remains poorly studied. Most Lucidotini species remain only superficially described, while internal characters—including those of terminalia and genitalia—which could inform species identification and phylogenetic relatedness, remain unknown. Upon studying eight Lucidotini species superficially looking likePhotinusandPhotinoidesMcDermott—all of which bearing long ventrobasal processes–we raised the hypothesis that they belonged to a genus yet to be recognized. MethodsHere, we analyzed 97 morphological characters of 32 lampyrid species spanning 17 of 30 Lucidotini genera under Bayesian Inference. ResultsWe found evidence for the recognition and description ofSaguassugen. nov.to include seven new species (Saguassu acutumsp. nov.,Saguassu grossiisp. nov.,Saguassu manauarasp. nov.,Saguassu rebellumsp nov.,Saguassu rourasp. nov.,Saguassu serratumsp. nov.andSaguassu sinuosumsp. nov.), in addition toPhotinus dissidensOlivier ((transferred herein, thus generatingSaguassu dissidenscomb. nov.), for which we also designate a lectotype and two paralectotypes). This previously neglected lineage of Lucidotini spans four South American biomes: Amazon, Atlantic Rainforest, Cerrado, and Pampa. Interestingly,Saguassuspecies span a gradient of morphologies related to signaling: fromLampyris-style ventrally bulging eyes, tiny antennae and no lanterns; intermediate eyes and antennae, with complete lanterns as inPhotinus; to small eyes and long antennae and small lanterns as in manyLucidotaLaporte.Saguassugen. nov.was consistently found closely related to the three other Lucidotini taxa with ventrobasal processes (i.e.,Alychnus,Photinoides, andPhotinus). We provide an occurrence map of and a dichotomous key toSaguassuspecies, thoroughly compare this genus with co-occurring Lucidotini genera, and suggest steps towards a revision of the Lucidotini tribe.

3. Molecular phylogenetics of Distephanus supports the recognition of a new tribe, Distephaneae (Asteraceae)

   https://doi.org/10.1093/botlinnean/boae025  

   Gostel, M R; Loeuille, Benoit; Santana, Mariana Henriques; Kelloff, Carol L; Chan, Raymund; Giraldes_Simões, Ana Rita; Larridon, Isabel; Funk, Vicki A (May 2024, Botanical Journal of the Linnean Society)

   Abstract Distephanus Cass. comprises 43 distinctive species of shrubs and small trees that have been placed historically within the ironweed tribe, Vernonieae (Asteraceae). Using the most expansive sampling of Distephanus to date, this study aims to test the monophyly of this genus and facilitate its classification. Molecular phylogenetic analyses were conducted using four molecular markers from the nuclear and plastid genomes. These data also supported divergence dating analyses that were performed to understand the timing of diversification events within Distephanus and other related genera as well as ancestral area reconstruction analyses to infer the biogegraphic history of species diversity in this group. Results from this study indicate that, as currently circumscribed, Vernonieae is not monophyletic and that Distephanus is, in fact, sister to a clade that comprises Vernonieae and another tribe, Moquinieae, which only includes two species restricted to Brazil. On the basis of these findings, Distephanus is classified in a new tribe that we describe here, Distephaneae. This new tribe comprises 41 species of Distephanus that are easily distinguished from Moquinieae and Vernonieae based on the presence of florets with yellow corollas and trinervate leaves.

4. Phylogenomics of North American cybaeid spiders (Araneae, Cybaeidae), including the description of new taxa from the Klamath Mountains Geomorphic Province

   https://doi.org/10.3897/zookeys.1226.140204

   The systematics of humble-in-appearance brown spiders (“marronoids”), within a larger group of spiders with a modified retrolateral tibial apophysis (the RTA Clade), has long vexed arachnologists. Although not yet fully settled, recent phylogenomics has allowed the delimitation and phylogenetic relationships of families within marronoids to come into focus. Understanding relationships within these families still awaits more comprehensive generic-level sampling, as the majority of described marronoid genera remain unsampled for phylogenomic data. Here we conduct such an analysis in the family Cybaeidae Banks, 1892. We greatly increase generic-level sampling, assembling ultraconserved element (UCE) data for 18 of 22 described cybaeid genera, including all North American genera, and rigorously test family monophyly using a comprehensive outgroup taxon sample. We also conduct analyses of traditional Sanger loci, allowing curation of some previously published data. Our UCE phylogenomic results support the monophyly of recognized cybaeids, with strongly supported internal relationships, and evidence for five primary molecular subclades. We hypothesize potential morphological synapomorphies for most of these subclades, bringing a robust phylogenomic underpinning to cybaeid classification. A new cybaeid genusSiskiyugen. nov.and speciesSiskiyu armillasp. nov.is discovered and described from far northern California and adjacent southern Oregon and a new species in the elusive genusCybaeozyga,C. furtivasp. nov., is described from far northern California.

5. Phylogenomics of the family Lachesillidae (Insecta: Psocodea: Psocomorpha)

   https://doi.org/10.1111/syen.12577  

   Saenz_Manchola, Oscar Fernando; Virrueta_Herrera, Stephany; D'Alessio, Lorenzo Mario; García_Aldrete, Alfonso Neri; Johnson, Kevin P (April 2023, Systematic Entomology)

   Abstract Lachesillidae is one of the largest families of bark lice and includes more than 420 described species, in 26 genera and three subfamilies. This family belongs in the suborder Psocomorpha, infraorder Homilopsocidea. The classification of Lachesillidae is based on male and female genital morphologies, but questions remain regarding the monophyly of the family and some of its genera. Here, we used whole genome and transcriptome data to generate a 2060 orthologous gene data matrix of 2,438,763 aligned bp and used these data to reconstruct the phylogenetic relationships of species of Lachesillidae and relatives. Taxon sampling included 24 species from Lachesillidae and 23 additional species belonging to related families from the infraorders Homilopsocidea and Caeciliusetae. Phylogenetic relationships reconstructed with maximum likelihood and coalescent‐based analyses indicated paraphyly of Lachesillidae, and monophyly of the tribe Graphocaeciliini and the genusLachesillawere also never recovered. Instability was observed in the position ofEolachesilla chilensis, which was recovered either as sister to Elipsocidae or to Mesopsocidae species, so we cannot conclusively determine the position of this genus within the Homilopsocidea. Given our results, a reclassification is necessary, but more taxon sampling of other species in Mesopsocidae and Peripsocidae would be useful to add to a tree in future before proposing a new classification.
