AbstractThe signaria group of the genus Semiothisa is a complex of 10 extremely similar species, most of which are host-specific on certain genera of coniferous trees An eleventh species, S. sexmaculata, is also treated in this revision because of its close resemblance to members of the signaria complex, although its true affinity appears to be with the liturata–bisignata group. The species are described and illustrated, and their synonymy, distribution, variation and biology are discussed in detail, including an account of industrial melanism in a population of S. pinistrobata. Two new species names are proposed, and eight lectotypes designated. The main center of distribution is northeastern North America, and all of the known species except S. fuscaria occur on this continent. The one Holarctic species, S. signaria, which is generally the commonest in collections, also has the widest range of host plants, feeding on at least six genera of coniferous trees.

AbstractTwo new species of the genus Lygus Hahn are described: potentillae from Canada, Alaska, and Colorado; and mexicanus from Mexico and Texas. Lygus abroniae Van Duzee is considered to be a typical member of the genus Lygus. The seasonal colour variations of the three species are noted, their relationships to other species in the genus are discussed, and their host plants are given.

AbstractTwo new species of metallic-green Coleophora are described from the Nearctic region: C. alabama Landry from coastal Alabama, U.S.A.; and C. mexicana Landry from the state of Tamaulipas, Mexico. Modifications to the key to adults of the Nearctic species of metallic-green Coleophora from Landry and Wright (1993) are provided to account for these new species. Larval host plants and natural history are unknown. Both species are tentatively placed in the ramitella group. Coleophora mayrella (Hübner), originally from the Old World but long established in North America, is recorded for the first time from South America (Chile and Argentina).

Two new species of Terfezia, Terfezia grisea and Terfezia cistophila, are documented from Spain and Greece, based on morphology and ITS-rDNA sequence data. Macro and micro descriptions with illustrations and ITS phylogenetic data for the two species are provided, which are discussed in relation to similar species in this genus and their host plants.

Primary Type

Two new species of Bembidion are described from river shores in North America. One, Bembidion mimbressp. nov., from the Gila River watershed in the lands of the Mimbres culture in New Mexico and Arizona, is closely related to the widespread Bembidion levigatum. DNA sequences from several linkage groups and morphology provide evidence of the distinctiveness of B. mimbres. The second, Bembidion corgenomasp. nov., has been the subject of recent genomic and transcriptomic studies. It belongs in the Bembidion transversale subgroup, and occurs from California north to British Columbia, east to Montana and Nevada. The B. transversale subgroup as a whole is reviewed, and morphological characters that distinguish B. corgenoma from the similar and sympatric B. transversale and B. erosum are described and illustrated. DNA sequences of these three species show no consistent differences in 28S, COI, CAD, and Topoisomerase, and a coalescent species delimitation analysis reveals no notable structure within the complex. This is the first known trio of species within Bembidion for which those genes provide no clear signal of species boundaries. A neotype is designated for the one name in the group that lacks a primary type, Bembidium haplogonum Chaudoir. Chromosomes of the new species and their relatives are as is typical for Bembidion, with eleven pairs of autosomes and an XY/XX sex chromosome system.

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Two New Species

Unclear boundaries between species hinder identification in the field and in herbaria, especially in species groups that can only be distinguished on the basis of subtle morphological and ecological features. One such taxon is Ficinia indica, widespread in the Greater Cape Floristic Region, growing on deep sandy soils between sea level and 1000 m elevation. Within its range, several phylogenetically related and morphologically similar species co-occur or occupy distinct habitats. Studies in herbaria show species in the Ficinia indica complex to be largely misidentified based on the use of qualitative information. Here, we investigate whether the six taxa recognized, based on one or a few characters, are supported as distinct species based on multivariate analysis of macro-morphological data. Two of the taxa were mostly separated whereas the other four taxa overlapped in multivariate space, but all the taxa could be distinguished using a single or a combination of morphological and ecological characters. We uphold the four previously recognized taxa (Ficinia argyropus, F. elatior, F. indica, F. laevis) as species, describe two new species (F. arnoldii and F. montana), and provide a dichotomous key for their identification.
