Title: A review of Nearctic Lathrobium (Coleoptera, Staphylinidae), with revision and descriptions of new flightless species from the mountains of the southeastern U.S.
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.  more » « less

    The genus-level taxonomy of the ant subfamily Leptanillinae (Hymenoptera: Formicidae) is here revised, with the aim of delimiting genus-level taxa that are reciprocally monophyletic and readily diagnosable based upon all adult forms. This new classification reflects molecular phylogenetics and is informed by joint consideration of both male and worker morphology. Three valid genera are recognized in the Leptanillinae:Opamyrma,Leptanilla(=Scyphodonsyn. nov.,Phaulomyrma,Leptomesites,Noonillasyn. nov.,Yavnellasyn. nov.), andProtanilla(=Anomalomyrmasyn. nov.,Furcotanilla).LeptanillaandProtanillaare further divided into informal, monophyletic species groups. Synoptic diagnoses are provided for all genera and informal supraspecific groupings. In addition, worker-based keys to all described species within the Leptanillinae for which the worker caste is known are provided; and male-based keys to all species for which males are known, plus undescribed male morphospecies for which molecular data are published. The following species are described as new:Protanilla wallaceisp. nov.,Leptanilla acherontiasp. nov.,Leptanilla belantansp. nov.,Leptanilla bethyloidessp. nov., andLeptanilla najaphallasp. nov.

    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.

    The marine ribbon worm genusTetranemertesChernyshev, 1992 currently includes three species: the type speciesT. antonina(Quatrefages, 1846) from the Mediterranean Sea,T. rubrolineata(Kirsteuer, 1965) from Madagascar, andT. hermaphroditica(Gibson, 1982) from Australia. Seven new species are described:T. bifrostsp. nov.,T. ocelatasp. nov.,T. majinbuuisp. nov., andT. pastafariensissp. nov.from the Caribbean Sea (Panamá), and three species,T. unistriatasp. nov.,T. paulayisp. nov., andT. arabicasp. nov., from the Indo-West Pacific (Japan and Oman). As a result, an amended morphological diagnosis of the genus is offered. To improve nomenclatural stability, a neotype ofTetranemertes antoninais designated from the Mediterranean. The newly described species, each characterized by features of external appearance and stylet apparatus, as well as by DNA-barcodes, form a well-supported clade withT. antoninaon a molecular phylogeny of monostiliferan hoplonemerteans based on partial sequences of COI, 16S rRNA, 18S rRNA, and 28S rRNA. Six of the seven newly described species, as well asT. rubrolineata, possess the unusual character of having a central stylet basis slightly bilobed to deeply forked posteriorly in fully grown individuals, a possible morphological synapomorphy of the genus. In addition, an undescribed species ofTetranemertesis reported from the Eastern Tropical Pacific (Panamá), increasing the total number of known species in the genus to eleven.

    This revision is based on sampling efforts over the past three decades in the southern Appalachian Mountains which have providedNesticus(Araneae, Nesticidae) collections of approximately 2100 adult specimens from more than 475 unique collecting events. Using a “morphology first” framework we examined recently collected specimens plus museum material to formulate morphology-based species hypotheses for putative new taxa (discovery phase). Using sequence capture of nuclear ultraconserved elements (UCEs) we analyzed 801 nuclear loci to validate new (and prior) morphology-based species hypotheses (validation phase) and reconstructed a robust backbone phylogeny including all described and new species. Sanger sequencing and UCE-bycatch were also used to gather mitochondrial data for more than 240 specimens. Based on our integrative taxonomic framework ten newNesticusspecies are herein described, includingN. binfordaesp. nov.,N. bondisp. nov.,N. caneisp. nov.,N. cherokeensissp. nov.,N. dellingerisp. nov.,N. dykemanaesp. nov.,N. jemisinaesp. nov.,N. lowderisp. nov.,N. roanensissp. nov., andN. templetonisp. nov.Previously unknown males are also described forN. bishopiGertsch, 1984,N. crosbyiGertsch, 1984, andN. silvanusGertsch, 1984, as well as the previously unknown female forN. mimusGertsch, 1984. Based on combined evidenceN. cooperiGertsch, 1984 is placed in synonymy withN. reclususGertsch, 1984. Overall, the montane radiation of AppalachianNesticusreveals a general lack of species sympatry and compelling biogeographic patterns. Several regionalNesticustaxa are rare, microendemic habitat specialists that deserve conservation attention and detailed future monitoring as conservation sentinels.

    The rarely encountered spider genusHexurellaGertsch & Platnick, 1979 includes some of the smallest mygalomorph spiders in the world, with four poorly known taxa from central and southeastern montane Arizona, southern California, and northern Baja California Norte. At time of description the genus was known from fewer than 20 individuals, with sparse natural history information suggesting a vagrant, web-building, litter-dwelling natural history. Here the first published taxonomic and natural history information for this taxon is provided in more than 50 years, working from extensive new geographic sampling, consideration of male and female morphology, and sequence capture-based nuclear phylogenomics and mitogenomics. Several new species are easily diagnosed based on distinctive male morphologies, while a complex of populations from central and northern Arizona required an integrative combination of genomic algorithmic species delimitation analyses and morphological study. Four new species are described, includingH. ephedrasp. nov.,H. uwiiltilsp. nov.,H. xericasp. nov., andH. zassp. nov.Females ofH. encinaGertsch & Platnick, 1979 are also described for the first time. It is predicted that additional new species will ultimately be found in the mountains of central and northwestern Arizona, northern mainland Mexico, and the Mojave Desert of California.
