   The genus-level classification of the ant subfamily Ponerinae (Hymenoptera: Formicidae) is revised based on a comprehensive phylogenomic analysis of more than 2,300 ultraconserved element (UCE) loci across 1,170 sampled specimens representing 1,020 taxa (600 valid species and 420 morphospecies) and all described ponerine genera known from workers. While most previously defined genus groups are recovered as monophyletic, several genera are shown to be polyphyletic or paraphyletic. To resolve these inconsistencies, four new genera are described:Boltonoponegen. nov.,Makebaponegen. nov.,Subiridoponegen. nov., andSritoponeragen. nov.Xiphopeltastat. rev.is revalidated andEuponerais restricted by expandingFisheroponeto absorb a paraphyletic assemblage.Mesoponerais split into four lineages, resulting in transfers toMakebapone,Subiridopone, andXiphopelta.Iroponerasyn. nov.is synonymized underCryptoponeand additional new synonymies at both the generic and species levels are established. Morphological diagnoses are revised for each affected genus, and updated species lists and new combinations are provided. The updated classification recognizes 54 valid genera within Ponerinae and acknowledges an additional lineage that will be formally described in a subsequent publication. To support identification and comparative studies, revised keys to all extant Ponerinae genera are provided, presented by biogeographic region (African and Malagasy, Palearctic–Indomalaya–Australasia, and New World). This classification is intended to provide a stable, phylogenetically informed framework for future research on ponerine ants.

   The ant subfamily Leptanillinae (Hymenoptera: Formicidae) consists of minute soil-dwelling species, with several genera within this clade being based solely upon males, including Yavnella Kugler. The dissociation of males and workers has resulted in taxonomic confusion for the Leptanillinae. We here describe the worker caste of Yavnella, facilitated by maximum-likelihood and Bayesian inference from 473 partitioned ultra-conserved element loci, this dataset including 49 other leptanilline species, both described and undescribed. Yavnella laventa sp. nov. is described from seven worker specimens collected in south-western Iran from the Milieu Souterrain Superficiel, a subterranean microhabitat consisting of air-filled cavities among rock and soil fragments, which is subject to similar environmental conditions as caves. This species has bizarrely elongated appendages, which suggests that it is confined to cavities, in contrast with the soil-dwelling behaviour observed in other leptanilline ants. Based on its gracile phenotype relative to other Leptanillinae, Y. laventa shows remarkable adaptations for subterranean life, making it one of a very few examples of this syndrome among the ants. Moreover, the discovery of the worker caste of Yavnella expands our morphological knowledge of the leptanilline ants. We provide worker- and male-based diagnoses of Yavnella, along with a key to the genera of the Leptanillinae for which workers are known. The worker caste of Yavnella as known from this species is immediately recognisable, but the possibility must be noted that described workers of Leptanilla may in fact belong to Yavnella. Further molecular sampling is required to test this hypothesis. ZooBank: urn:lsid:zoobank.org:pub:A54A5766-F35A-4074-9353-1C70FE3955D3

3. Revision of Vanuatubasis Ober & Staniczek, 2009 (Odonata, Coenagrionidae), with description of seven new species

   Saxton, Natalie A; Marinov, Milen G; Bybee, Seth M (November 2022, ZooKeys)

   VanuatubasisOber & Staniczek, 2009 is an endemic genus of damselfly found on the island archipelago of Vanuatu. Previously only three species were assigned to the genus. Here, all known species ofVanuatubasisare formally described and treated, including the association of females for known species. The following new congeners are also described:V. discontinuasp. nov.,V. evelynaesp. nov.,V. insularivorumsp. nov.,V. kapularumsp. nov.,V. nunggolisp. nov.,V. rhomboidessp. nov., andV. xanthochroasp. nov.from material collected across six different islands. An illustrated key to both males and females of all species withinVanuatubasisis provided as well as distributions for all known species.

4. A review of Nearctic Lathrobium (Coleoptera, Staphylinidae), with revision and descriptions of new flightless species from the mountains of the southeastern U.S.

   Haberski, Adam; Caterino, Michael S. (April 2024, ZooKeys)

   Species of the genusLathrobiumGravenhorst (Coleoptera: Staphylinidae: Paederinae) from North America north of Mexico are reviewed and 41 species are recognized. Morphology and mitochondrial COI sequence data were used to guide species designations in three flightless lineages endemic to the southern Appalachian Mountains, a biologically diverse region known for cryptic diversity. Using a combination of phylogeny, algorithm-based species delimitation analyses, and genitalic morphology, five new cryptic species are described and possible biogeographic scenarios for their speciation hypothesized:L. balsamenseHaberski & Caterino,sp. nov.,L. camplyacraHaberski & Caterino,sp. nov.,L. islaeHaberski & Caterino,sp. nov.,L. lividumHaberski & Caterino,sp. nov.,L. smokienseHaberski & Caterino,sp. nov.Five additional species are described:L. absconditumHaberski & Caterino,sp. nov.,L. hardeniHaberski & Caterino,sp. nov.,L. lapidumHaberski & Caterino,sp. nov.,L. solumHaberski & Caterino,sp. nov., andL. thompsonorumHaberski & Caterino,sp. nov.Two species are transferred fromLathrobiumtoPseudolathraCasey:Pseudolathra parcum(LeConte, 1880),comb. nov.andPseudolathra texana(Casey, 1905),comb. nov.Twenty-six names are reduced to synonymy. Lectotypes are designated for 47 species. Larvae are described where known, and characters of possible diagnostic value are summarized. Species diagnoses, distributions, illustrations of male and female genitalia, and a key toLathrobiumspecies known from the Nearctic region (including several introduced species) are provided.

5. A new genus of soft coral (Octocorallia, Malacalcyonacea, Cladiellidae) and three new species from Indo-Pacific coral reefs

   https://doi.org/10.3897/zookeys.1188.110617  

   McFadden, Catherine S; Benayahu, Yehuda; Samimi-Namin, Kaveh (January 2024, ZooKeys)

   Molecular systematic studies of the anthozoan class Octocorallia have revealed widespread incongruence between phylogenetic relationships and taxonomic classification at all levels of the Linnean hierarchy. Among the soft coral taxa in order Malacalcyonacea, the family Alcyoniidae and its type genusAlcyoniumhave both been recognised to be highly polyphyletic. A recent family-level revision of Octocorallia established a number of new families for genera formerly considered to belong to Alcyoniidae, but revision ofAlcyoniumis not yet complete. Previous molecular studies have supported the placement ofAlcyonium verseveldti(Benayahu, 1982) in family Cladiellidae rather than Alcyoniidae, phylogenetically distinct from the other three genera in that family. Here we describe a new genus,Ofwegenumgen. nov.to accommodateO. verseveldticomb. nov.and three new species of that genus,O. coronalucissp. nov.,O. kloogisp. nov., andO. collisp. nov., bringing the total number of species in this genus to four.Ofwegenumgen. nov.is a rarely encountered genus so far known from only a few locations spanning the Indian and western Pacific Oceans. We present the morphological characters of each species and use molecular data from both DNA barcoding and target-enrichment of conserved elements to explore species boundaries and phylogenetic relationships within the genus.
