Minute aphids belonging to the species Myzus fataunae Shinji (Hemiptera: Aphididae) were found at a nursery in Seminole County, Florida. Morphological and molecular data support this determination. The Florida population only colonized species of Pilea Lindl. in our host range experiments. It did not colonize Fatoua villosa. Nakai. Likewise, it did not colonize tested common Florida species of Urticaceae other than Pilea spp. Myzus fataunae is adventive, and it appears to be established in the United States.

Orsilochides scurrilis (Stål) (Hemiptera: Heteroptera: Scutelleridae) is reported from the United States for the first time based on a specimen collected in Santa Cruz County, Arizona. A key to separate the U.S. species of Orsilochides Kirkaldy is provided. In addition, host plant records and distribution of the other two species of Orsilochides that occur in the U.S., Orsilochides guttata (Herrich-Schäffer) and Orsilochides stictica (Dallas), are analyzed through a combination of digital photo records and museum specimens.

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 spe­cies. Aphalara persicaria Caldwell is redescribed and separated from similar species. Aphalara persicaria var. cubana Caldwell is confirmed as a junior synonym of Aphalara persicaria. The Florida records of Craspedo­lepta 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 Leu­ronota 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 com

The occurrence of the orchid bee Euglossa dilemma Bembé and Eltz (Hymenoptera: Apidae) is recorded for the first time for the island of Hispaniola in the Greater Antilles. Males were observed visiting varieties of sweet basil plants (Ocimum basilicum Linnaeus (Lamiaceae)) to obtain fragrances used during courtship and reproduction. Our observations showed that the species is established in Hispaniola and that it does not require the presence of orchids for reproductive success, being able to adapt to new plant resources it finds in the areas it colonizes. These observations correspond to what was found in Florida, United States, where Euglossa dilemma was also recently introduced. It is not clear how the species was introduced to Hispaniola, but Euglossa dilemma is clearly an adventive species that is colonizing the Antilles in addition to peninsular Florida. Se registra por primera vez la presencia de la abeja de orquídeas Euglossa dilemma Bembé y Eltz (Hymenoptera: Apidae) para la isla La Española, Antillas Mayores. Fueron observados machos acudiendo a varie­dades de plantas de albahaca (Ocimun basilicum Linnaeus) para obtener fragancias utilizadas durante el cortejo y la reproducción. Nuestras observaciones demuestran que la especie está establecida en La Española y que no requiere de la presencia de orquídeas para el éxito reproductivo, pudiendo adaptarse a los nuevos recursos vege­tales que encuentra en las áreas que coloniza. Estas observaciones se corresponden con lo hallado en La Florida, Estados Unidos, donde fue introducida recientemente. Euglossa dilemma es una especie no nativa que además de La Florida está colonizando las Antillas.

Brachyplatys subaeneus (Westwood) (Hemiptera: Plataspidae), is reported from Miami Beach, FL, the first report from the United States. It was noticed first on a photo-sharing site (iNaturalist) providing an example of the importance of these sites for helping to track introduced species. Information on distribution, host plants and potential spread are provided along with photos and taxonomic characters to assist with identification of this recently introduced species.

Выявлен видовой состав сосудистых растений лесопарка, проведен его систематический и эколого-биологический анализ, анализ составляющих флору эколого-генетических фракций, анализ распределения видов по жизненным формам К. Раункиера и И. Г. Серебрякова, проанализирован спектр эколого-ценотических групп и также групп видов по отношению к фактору увлажнения. Показано, что в составе флоры преобладают виды индигенной и апофитной фракций. Значительная доля апофитных видов может свидетельствовать об интенсивном процессе изменения растительного покрова под влиянием антропогенных факторов и приспособления видов к существованию в нарушенных место обитаниях (синантропизация флоры). Установлено, что 38 % видов являются иноземными, их происхождение не связано с естественным процессом флорогенеза и появление на изучаемой территории обусловлено деятельностью человека. Среди видов адвентивной фракции было выявлено 3,1 % инвазионных видов (эргазиофитов). Эти виды, внедряясь в естественные местообитания с коренной растительностью, распространяются там настолько, что вытесняют её. По широтному распространению бореальные виды преобладают в индигенной фракции, полизональные – в апофитной фракции, неморальные – в адвентивной относительной; в адвентивной фракции большинство видов средиземноморского, ирано-туранского и североамериканского происхождения. По системе жизненных форм К. Раункиера гемикриптофиты преобладают в индигенной и апофитной фракциях, фанерофиты – в адвентивной и адвентивной относительной. По системе жизненных форм И. Г. Серебрякова в индигенной и апофитной фракциях больше всего представлены многолетние травы с преобладанием многолетних корневищных, среди адвентивной и адвентивной относительной фракций преобладают древесные растения. По отношению к фактору увлажнения во всех фракциях абсолютным большинством преобладают мезофиты. По типам местообитаний в индигенной и адвентивной относительной фракциях доминируют лесные виды, в апофитной – лугово-рудеральные, в адвентивной –, We identified species composition of vascular plants of forest park, conducted its systematic and ecological-biological analysis, made analysis of ecological-genetic fractions of flora as well as categorizing of plant species to Raunkiaer’s and I.G. Serebraykov’s systems of life-form categories; spectrum of the ecological-coenotical groups and species groups related to moisture were analyzed. It was demonstrated that species of indigenous and apophytous fractions are dominating in the flora. A significant proportion of apophytous species may indicate intensive changes in plant cover under the influence of anthropogenic factors and adaptations of species to existence in disturbed habitats (synanthropisation of flora). It was found that 38 % of species were alien, their origin was not connected with the natural process of florogenesis and their emergence in the study area were due to human activities. Among the species of adventive fraction 3,1 % of invasive species (ergasiophytes) were identified. These species after penetrating into natural habitats with native vegetation spread to such extent that replace it. As for latitudinal distribution the boreal species prevail in indigenous fraction, polyzonal – in apophytous fraction, nemoral – in relative adventive fraction; in the adventive fraction the majority of species are of Mediterranean, Iranian-Turanian and North American origin. According to the system of Raunkiaer’s life-forms the hemicryptophytes prevail in indigenous and apophytous fractions, phanerophytes prevail in adventive and adventive relative ones. According to the I.G. Serebryakov’s system of life-forms perennial grasses are dominating in indigenous and apophytous factions with the majority of rhizomatous species, woody plants are dominating among adventive and adventive relative fractions. In relation to moisture mesophytes are dominating in all fractions. According habitat types forest species prevail in indigenous and adventive relative fractions, m
