Revision of the genusSiphantaStål (Homoptera : Fulgoroidea : Flatidae)

Abstract

Siphanta ~t i l is redefined to include Parasalurnis Distant and Siphantoides Distant. Lombokia Distant is synonymized with Siphanta. The genus contains 40 species, 25 of which are described as new. Descriptions, redescriptions, measurements and illustrations are given of all 40 species. A key for separation of the species is included. The following new species are described: Kirkaldy = S. patruelis (St& Parasalurnis infumata Distant = Siphanta patruelis (~t i l ) ; Lombokia everefti Distant = Siphanta patruelis (st@; Parasalurnis insularis Distant = Siphanta roseicincta (Walker). The other species recognized are S. acuta (Walker), S. galeata Kirkaldy, S. nubecula Jacobi, S. anomala Jacobi, S. gregaria Jacobi, S. lucindae Kirkaldy, S. granulata Kirkaldy, S. rubra Schmidt and S. subgranulosa Kirkaldy.Revision of Siphanta 3 length of clavus length of tegrnen to apex of last branch of vein R width of tegmen from apex of clavus to costal margin level with end of costal cell length of vertex in midline width of vertex at base length of pronotum in midline length of frons in midline (from apex to frontoclypeal suture) maximum width of frons It maximum length of tegmen (in one species only)The following additional abbreviations were used in this work: AM Australian Museum, Type-species: Poeciloptera acuta Walker. Diagnostic FeaturesFrons slightly convex to flat, with median longitudinal carina. Lateral carinae very short or absent. Vertex flat, slightly undulate or slightly concave, meeting frons at carinate margin which may be triangularly produced, roundly convex or nearly straight. Pronotum medially flat between lateral carinae which curve posterolaterally and do not reach hind margin of pronotum; posterior margin broadly concave. Mesonotum with 2 lateral carinae, flattish medially. Occasionally, median carina faintly developed. Tegmen triangular with sutural angle obtusely rounded, right-angled or slightly acute. Tegmen lacking apical lines. Hind tibia with 1 spine on shaft. BiologyThe life history of Siphanta acuta was described by Myers (1922) in New Zealand, and Fletcher (1979a) briefly outlined the egglaying of the same species. As the ovipositors of all species of Siphanta are similar, it is likely that all species oviposit in a similar manner.Some species of the genus appear to have fairly wide food-plant ranges. This is evidenced by records of various species on exotic plants. Insufficient information is available to indi-4 M. J.

The following are the known food plants of species of Siphanta.

“…Registros de ocurrencias. Se obtuvieron registros de la literatura (Fletcher 1985; Pham y Thinh 2019), y de las bases de datos en línea "Integrated Digitized Biocollections" (iDigBio 2019), "Tri-Trophic Thematic Collection Network" (TTD-TCN 2019), y "Global Biodiversity Information Facility" (GBIF 2019a, 2019b). De esta última, se consideraron registros fotográficos de iNaturalist, seleccionando sólo aquellos con fotografías de ejemplares adultos reconocibles fuera de Australia, debido a la existencia de especies morfológicamente afines en este país.…”

“…Siphanta acuta (Walker, 1851) (Hemiptera: Flatidae) es una especie originaria de Australia que ha sido registrada en Nueva Zelanda, Estados Unidos de América (Islas Hawái y California), Islas Azores (Portugal), Sudáfrica y Vietnam (Fletcher 1985;Pham y Ta 2009;Larivière et al 2010;Borges et al 2013). Es una especie multivoltina y generalista en su dieta, afectando plantas cultivadas como zarzas (Rubus spp.…”
