Psyllids have shifted lately into general awareness as vectors of pathogens causing serious plant diseases, as pests in agriculture and forestry or as potential control agents of alien invasive weeds. These small insects are plant sap feeders which are generally very host specific. In addition, related psyllid species tend to develop on related plant species. This makes them an ideal group for studies on insect–plant cospeciation. A sound taxonomic and phylogenetic base is a prerequisite for successful pest control and meaningful research on insect–plant interactions. Currently almost 4000 named species of Psylloidea exist worldwide of which half was described in the last three decades. Despite this tremendous progress there are at least another 4000 species which remain undescribed particularly in Africa, South America and tropical Asia. Since White and Hodkinson’s seminal paper in 1985 a series of studies tested their classification with additional taxa using morphological and molecular techniques. In 2012 Burckhardt and Ouvrard proposed a new classification. Five of their families (Calophyidae, Carsidaridae, Homotomidae, Phacopteronidae and Triozidae) are identical with or similar to those of White and Hodkinson but three differ fundamentally from previous classifications (Aphalaridae, Liviidae and Psyllidae). Many of the recognised families and subfamilies are restricted more or less exclusively to a single plant taxon, e.g. Calophyidae, Phacopteronidae and Rhinocolinae to Sapindales, Carsidaridae to Malvaceae, Homotomidae to Moraceae, Spondyliaspidinae to Myrtaceae, and many Psyllidae to Fabaceae. The 1000 described species of Triozidae, in contrast, have colonised many families of dicots and, a few, even monocots and conifers. Several analyses suggest that cospeciation may be less important than geographical vicariance to explain the observed species richness in psyllids, and that shifts to new host taxa are frequent.

<P>Moriphila furva Burckhardt & Cho, gen. and sp. nov., is described from the mountain region in north eastern South Korea. Adults were collected on Morus australis which is a likely host. We provide morphological evidence that the new monotypic genus constitutes the probable sister group of the afrotropical Phytolyma whose species develop on Milicia and Morus (Moraceae). Differences between the two genera are detailed and the phylogenetic relationships to other members of Homotomidae: Macrohomotominae, to which the new genus belongs, are discussed. The host relationships of Psylloidea associated with Moraceae are reviewed. The latter constitutes the fifth most important host taxon of Psylloidea even though it is only a moderately large family of angiosperms in terms of constituent species. Moraceae have been colonised by psyllids at least five times independently. Following new combinations are proposed: Homotoma brevis (Li, 1993), comb. nov. and Homotoma microphyllae (Li & Yang, 1991), comb. nov. (both from Caenohomotoma Yang & Li, 1981). </P>
The jumping plant-lice of Laos (Hemiptera: Psylloidea)
조건호,Daniel BURCKHARDT,Daniel Burckhardt,이승환 한국응용곤충학회 2017 Journal of Asia-Pacific Entomology Vol.20 No.2
The jumping plant-lice of Laos are reviewed based on material collected during recent expeditions by theMoravianMuseum( 1997–2011), the NaturhistorischesMuseumBasel (2003–2012) and the Seoul National University (2012–2015). To date, only three psyllid species, viz. Diaphorina citri, Heteropsylla cubana and Pseudophacopteron tuberculatum, have been recorded fromLaos. In thematerial at hand, 49 species (of 6 families and 27 genera) are represented. This collection includes the three previously reported species and 22 species reported for the first time from Laos. Twenty-four species are identified only to genus due to insufficient material. The following nomenclatorial changes are formally proposed: Insnesia drypetisuga (Li, 2004), comb. nov. (from Auchmerina); Insnesia longitaenialis (Li, 2011), comb. nov. (from Auchmerina); Insnesia maculosa (Fang & Yang, 1986), comb. rev. (from Auchmerina); Insnesia yunnanensis (Li, 2011), comb. nov. (from Auchmerina); Trioza maculata (Yang, 1984) = Triozopsis ruiliensis Li, 2011, syn. nov.
A review of the Korean pear psyllids (Hemiptera: Psyllidae)
Geonho Cho,Hiromitsu Inoue,Daniel Burckhardt,Seunghwan Lee 한국응용곤충학회 2016 한국응용곤충학회 학술대회논문집 Vol.2016 No.04
Pear psyllids are of major economic concern in Korea. In the literature five nominal species, including two West Palaearctic taxa, are reported from the Peninsula. The Korean pear psyllids, member of the large genus Cacopsylla, are reviewed here to comprise four species. Previous Korean records of C. pyrisuga (Foerster) are misidentification of C. burckhardti Luo et al. whereas those of C. pyricola (Foerster) concern C. maculatili Li and probably C. jukyungi (Kwon) stat. rev., comb. nov. (from Psylla). The latter, that is commonly found in pear orchards, occurs also in Japan where it was misidentified as C. chinensis. The differences between C. jukyungi and C. cinereosignata syn. nov. reflect seasonal dimorphism. For this reason, we synonymise the two. C. maculatili and C. qiuzili Li are shown to represent the winter and the summer form of the same species and are, therefore, synonymised as C. maculatili = C. qiuzili syn. nov. C. jukyungi and C. sandolbaea (Park & Lee) are redescribed, a key to the adult of the four species and short biological notes are provided.

Bactericera gobica (Loginova) is reported for the first time fromKorea on Chinese boxthorn, Lyciumchinense Mill. In North and Northeast China, B. gobica is an important pest of boxthorn (Lycium chinense and L. barbarum) whose fruits, known as wolfberry or goji berry, are used in traditional medicine. B. gobica is diagnosed and illustrations of taxonomically relevant structures are provided along with information on its biology.Worldwide 17 psyllid species are associated with Lycium. These belong to the genera Bactericera (5 spp.), Diaphorina (2 spp.) and Trioza (1 sp.) in the Old World aswell as Bactericera (2 spp.) and Russelliana (7 spp., including 5 undescribed spp.) in the New World. One species of each Bactericera and Russelliana is polyphagous which is very rare in psyllids.

To date, only three psyllid species, viz. Diaphorina citri, Heteropsylla cubana and Pseudophacopteron tuberculatum, are recorded from Laos.

This collection includes the three previously reported species and eight species reported for the first time from Laos. Eleven species are identified only to genus due to insufficient material.
On the taxonomy of Korean jumping plant-lice (Hemiptera: Psylloidea)
CHO, GEONHO,BURCKHARDT, DANIEL,LEE, SEUNGHWAN Magnolia Press 2017 Zootaxa Vol.4238 No.4
<P>The taxonomy of jumping plant-lice from South Korea is revised based on extensive, recently collected material and specimens preserved in several collections. Three species are described as new (Craspedolepta yongjungi, Cacopsylla baccatae and Cyamophila floribundae spp. nov.) and 11 species are recorded from South Korea for the first time (Aphalaridae 2, Homotomidae 1, Liviidae 1, Psyllidae 6, Triozidae 1). One genus and 13 species are synonymised, two species are removed from synonymy and two species are recombined. Comments on the taxonomy are provided and previous misidentifications are discussed. </P>

Systematics of the east Palaearctic pear psyllids (Hemiptera: Psylloidea: Psyllidae)
Geonho Cho,Daniel Burckhardt,Hiromitsu Inoue,Xinyu Luo,Seunghwan Lee 한국응용곤충학회 2017 한국응용곤충학회 학술대회논문집 Vol.2017 No.10
The confused taxonomy of the east Palaearctic pear psyllids, serious pests on cultivated pear, is reviewed. Fifty-sixnominal species have been reported from Pyrus, 25 of which we consider valid and ten as not being associated withPyrus. Our taxonomic revision suggests that, in Korea, four Cacopsylla species develop on pear. Three species occuralso in Japan. New synonyms are suggested and seasonal dimorphism are critically discussed.Key words : Psyllidae, Cacopsylla, taxonomy, host plant, Pyrus, Rosaceae, Manchrian pear, Asian pear, European pear, China,Japan, South Korea, Russian Far East
