Psyllids are an economically important group of insects. Several species are serious emerging pests with regulatory significance. About 20 adventive species have been discovered in Florida in the past 20 years, including several pests. Additionally, five species new to science have been found. We provide an annotated checklist of Florida species with taxonomic information and identification tools, including keys to Florida genera and known species. Seventy species of Psylloidea currently are reported from Florida. Forty-one are native to Florida, with 12 endemic to the state. Twenty are adventive, the majority being from the Neotropics. One was introduced deliberately for biological control, seven represent temporary populations (eradicated, reared in quarantine), and one is a dubious record. Craspedolepta euthamiae Burckhardt and Halbert, new species, Katacephala wineriterae Burckhardt and Halbert, new species, Pseudophacopteron gumbolimbo Burckhardt and Halbert, new species, Nothotrioza longipedis Burckhardt and Halbert, new species, and Trioza myresae Burckhardt and Halbert, new species are described from Florida and are native endemic spe- cies. Aphalara persicaria Caldwell is redescribed and separated from similar species. Aphalara persicaria var. cubana Caldwell is confirmed as a junior synonym ofAphalara persicaria. The Florida records ofCraspedo - lepta spp. are revisited and revised, including Craspedolepta euthamiae Burckhardt and Halbert, new species. Bactericera nigrilla (Crawford), new combination, revived status is recognized from Florida, redescribed, and distinguished from similar species. Rhinopsylla caldwelli Tuthill is transferred to Kuwayama Crawford and becomes Kuwayama caldwelli (Tuthill), new combination. Trioza maritima Tuthill is transferred to Leu- ronota Crawford and becomes Leuronota maritima (Tuthill), new combination. Species of Bactericera Puton on Salix L. (Salicaceae) in North America are reviewed. Bactericera flori (Crawford), new combination, new status. is determined to be the correct name for Trioza assimilis Crawford nec Flor (= Trioza flori Crawford, replacement name, = Trioza pomonae Aulmann, replacement name), and Trioza dubia Patch, new synonym. Lectotypes are designated for Trioza marginata Crawford, Trioza minuta Crawford, Trioza minuta similis Crawford, and Trioza nigra Crawford. Key words.

Psyllids can do direct damage to crops and ornamental plants, but possibly the most severe impacts come from transmitted plant pathogens, primarily fastidious prokaryotes (Halbert and Manjunath 2004). The establishment of Diaphorina citri Kuwayama and its associated plant pathogens has resulted in a 74% production decline in citrus, Florida’s signature crop (Singerman and Rogers 2020). Psyllids can travel with global trade in plant materials, a trend that has been noticeable in Florida in the past two decades. One of the most important assignments for the Florida Department of Agriculture and Consumer Services, Division of Plant Industry (DPI) is to find and monitor potential plant pests in the state. Florida is a sentinel state, with numerous seaports, airports, and extensive tourist traffic. Moreover, the climate of Florida is warm and humid, and the plant community includes a diverse assortment of ornamentals, crops, and native plants, providing an ideal environment for insects to establish viable populations. As a result, Florida has become home 2 · September 25, 2020 Halbert and Burckhardt to many exotic species (Frank and McCoy 1992, 1995). DPI has several hundred inspectors and fruit fly trappers whose job is to search for and submit arthropods for identification. Additionally, public and research associ- ate submissions, on-going trapping programs and miscellaneous surveys are a source for other new records for Florida, including those for psyllids. Most species found are relatively inconsequential additions to the ecosystem, but some become serious pests. This paper summarizes psyllids found in Florida, including relatively recent finds (subsequent to Hodkin- son 1988), provides additional notes on some rarely collected species, and provides descriptions of five species new to science. Several Florida species required additional taxonomic scrutiny because they were members of unresolved species complexes, including Aphalara persicaria Caldwell, Florida species of Craspedolepta Ender- lein, and Bactericera nigrilla (Crawford). These complexes are discussed in detail. Identification information also is provided. Materials and Methods Some of the psyllids reported here were collected by DPI and USDA-APHIS-PPQ inspectors. These submissions are part of the regular activities of the DPI diagnostics service. Other psyllids came from Florida suction traps. Suction traps are large machines made of 180 cm long, 38 cm diameter, PVC pipes, mounted vertically on posts about 45 cm above the ground level. The traps have an electric fan in the bottom to suck insects into

  • Homoptera: Psyllidae) in Hawaii
    Vol. 31, December 31,1992 177 Taxonomic Status and Host Range of Three HeteropsyUa spp. (Homoptera: Psyllidae) in Hawaii WALTER T. NAGAMINE, BERNARR R. KUMASH1RO, and LARRY M. NAKAHARA1 ABSTRACT. The laxonomic status of two species of Hftrrvpsytla in Hawaii was clarified after confusion arose because of inadequate identification keys and the collection of mixed popu lations from a common host plant. A third species of llrtrmfisylla was also discovered for the first time in Hawaii (hiring January 1986. Most range tests were conducted with nine leguminous plants, lletemfisylla rubana Crawford, a senior synonym of //. inetia (Sulc), completed its development on leucaena (Ijnuarna UucocephaUt (l.am.) de Wit) and monkeypod (Samanea saman (Jacq.) Mem); //. huasachae Caldwell on koa (Acacia koa Gray), monkeypcxl, and slender mimosa (Desmanlhus virgatus (I.) Willd.); and //. fusca Crawford on klu {Acacia farnesiana (1..) Willcl.). Clarification of the taxonomic status of two HeteropsyUa spp. present in Hawaii was made recently. The close resemblance of the species within this genus, in addition to the collection of mixed populations from a common host plant, led to some early confusion. At that time, the need for revision of the HeteropsyUa group precluded their identifications. Later, with the revision work completed (Brown 1985, Burckhardt 1986, 1987) and with assistance of collaborators R. Brown and I. Hodkinson2, D. Burckhardt3, D. Hollis4, and D. Miller and L. Russell5, the determinations of two HeteropsyUa spp., H. cubana Crawford and H. huasachae Caldwell, were made. A third species, H. fusca Crawford, was later identified by I. Hodkinson, R. Brown, and D. Hollis. A summary of the three psyllids in Hawaii is presented below.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

  • Phenotypic Landscape Inference Reveals Multiple Evolutionary Paths to C4 Photosynthesis
    RESEARCH ARTICLE elife.elifesciences.org Phenotypic landscape inference reveals multiple evolutionary paths to C4 photosynthesis Ben P Williams1†, Iain G Johnston2†, Sarah Covshoff1, Julian M Hibberd1* 1Department of Plant Sciences, University of Cambridge, Cambridge, United Kingdom; 2Department of Mathematics, Imperial College London, London, United Kingdom Abstract C4 photosynthesis has independently evolved from the ancestral C3 pathway in at least 60 plant lineages, but, as with other complex traits, how it evolved is unclear. Here we show that the polyphyletic appearance of C4 photosynthesis is associated with diverse and flexible evolutionary paths that group into four major trajectories. We conducted a meta-analysis of 18 lineages containing species that use C3, C4, or intermediate C3–C4 forms of photosynthesis to parameterise a 16-dimensional phenotypic landscape. We then developed and experimentally verified a novel Bayesian approach based on a hidden Markov model that predicts how the C4 phenotype evolved. The alternative evolutionary histories underlying the appearance of C4 photosynthesis were determined by ancestral lineage and initial phenotypic alterations unrelated to photosynthesis. We conclude that the order of C4 trait acquisition is flexible and driven by non-photosynthetic drivers. This flexibility will have facilitated the convergent evolution of this complex trait.
