Abstract>Three species are recognized in the North American genus Megetra LeConte. The most distinctive of these anatomically and ecologically is M. cancellata (Brandt and Erichson), which ranges discontinuously from Arizona and New Mexico to the state of Hidalgo in México and occurs in limited sympatry with both of its congeners. Megetra vittata (LeConte) ranges from northern Arizona to western Texas. It appears to be strictly allopatric with, and similar ecologically to, M. punctata, new species, which ranges from southern Arizona and New Mexico to Durango, México. Specific diagnoses are made on the basis of characters of adult and, for M. cancellata and M. punctata, larval anatomy. Intraspecific variation in several adult characters is analyzed. Notes on the seasonal distribution, habitat, and behavior of the adult beetles are included.

Selection Of

The eurybioid asters Oreostemma , Herrickia , Eurybia , and Triniteurybia form a complex that is part of the North American clade of tribe Astereae. They comprise 31 species of perennial herbs that are widely distributed on the continent. Previous analyses had shown poor resolution among the four genera and among the species, particularly within Eurybia (23 spp.), which includes diploids and polyploids. We investigated phylogenetic relationships within the group using the nuclear ribosomal ITS and ETS regions, in separate and combined parsimony and Bayesian analyses. We detected incongruence between the ITS and ETS regions when polyploids were included, and so only diploids were considered in the combined analyses. Eurybia pygmaea (Lindl.) G.L. Nesom is confirmed as a member of Symphyotrichum ; Eurybia is monophyletic once this species is re-classified. The eurybioids form a paraphyletic grade with Oreostemma, sister to the remaining taxa, followed in succession by Herrickia , Eurybia , and Triniteurybia , and with the latter genus sister to subtribe Machaerantherinae. Thus the xeric Machaerantherinae (x = 6, 5, 4) is nested within the grade of mesic eurybioids (x = 9). Although largely grouping together, the polyploid taxa of Eurybia apparently do not constitute a clade and their relationships to the diploid taxa and to each other could not be assessed further. Among the diploids, two clades emerge: one including the western Eurybia integrifolia (Nutt.) G.L. Nesom and Eurybia sibirica (L.) G.L. Nesom, and the southeastern Eurybia eryngiifolia (Torr. & A. Gray) G.L. Nesom; and a second including the western Eurybia radulina (A. Gray) G.L. Nesom, the eastern cordate-leaved (sect. Eurybia) and the narrow-leaved, mostly coastal plain species of Eurybia. Our analyses, therefore, do not support the current classifications of Eurybia.

Name Changes

The family Cleomaceae is in need of taxonomic revision, which begins here with a set of taxa informally recognized as the North American cleomoid clade. This group is evaluated first because molecular-based analyses almost comprehensively sample this lineage. These investigations revealed that the two largest genera, Cleomella and Peritoma, are para- or polyphyletic. Strong support from molecular data necessitates name changes for these taxa. Furthermore, controversy exists on the recognition of the remaining genera, owing to morphological variation and specialization. Three possible classification scenarios are described to accommodate monophyletic lineages based on previously-published evidence. The option to create the single large genus Cleomella is proposed, and as a result one new name, Cleomella oxystyloides, is provided, and 12 new combinations are made: C. arborea, C. arborea var. angustata, C. arborea var. globosa, C. californica, C. jonesii, C. lutea, C. multicaulis, C. palmeri, C. platycarpa, C. refracta, C. serrulata, and C. sparsifolia. Two lectotypes and one isolectotype are designated, and another lectotype is confirmed.
