Jumping plant-lice of the Paurocephalinae (Insecta, Hemiptera, Psylloidea): systematics and phylogeny
Much confusion exists with respect to the content and definition of the psyUid subfamily
Paurocephalinae. Based on a cladistic analysis of 22 morphological characters (16 adult
and 6 larval), the subfamily is redefined to comprise the following five valid genera:
Aphorma (3 species), Camarotoscena (12 valid species, with 1 new synonymy), DiC/idophlebia
(= Aconopsylla, Haplaphalara, Paraphalaroida, Sinuonemopsylla and Woldaia;
24 species), Paurocephala (52 species) and Syntomoza (= Anomoterga and Homalocephata;
7 species). The tribe Diclidophlebiini is synonymised with the subfamily Paurocephalinae.
The seven new generic synonymies produce 25 new species combinations. A
key to genera for adults and fifth instar larvae is presented. In their revised definitions
the genera exhibit relatively restricted distributions and host ranges: Aphorma: Palaearctic,
Oriental - Ranunculaceae; Camarotoscena: Palaearctic - Salicaceae; Diclidophtebia:
pantropical - Tiliaceae, Malvaceae, Sterculiaceae, Melastomataceae, Rhamnaceae,
Ulmaceae and Euphorbiaceae; Paurocephala: Old World tropics - Moraceae, Urticaceae.
Ulmaceae (all Urticales), Malvaceae. Sterculiaceae (all Malvales) and Clusiaceae (rheales);
Syntomoza: Oriental, Afrotropical, Palaearctic - Flacourtiaceae, Salicaceae. The
following taxa which have been referred to the Paurocephalinae are transferred to other
taxa: Atmetocranium to the Calophyidae and Primascena to the Aphalaroidinae;
Pseudaphorma is symonymised with Aphatara, and P. astigma with A. polygoni; the position
of Strophingia is confirmed in the Strophingiinae.peer-reviewe
Taxonomy and phylogeny of the Old World jumping plant-louse genus Paurocephala (Insecta, Hemiptera, Psylloidea)
Fifty-one species are recognized in the genus Paurocephala, with an additional
14 species which remain unnamed. Thirty-five species are described as new, and
five species are synonymized: P. pumilae and P. zhejiangensis with P. chonchaiensis,
P. debregeasiae with P. sauteri, and P. guangxiensis and P. tremae with P.
trematos. Two varieties, P. psylloptera maculipennis and P. psylloptera setifera,
are raised to species level. P. bifasciata is reinstated from former synonymy with
P. chonchaiensis, and Anomoterga kleinhofiae is transferred back to Paurocephala.
Lectotypes are designated for P. brevicephala, P. chonchaiensis, P. psylloptera, P.
sauteri, P. seti/era and P. wilderi. The four New World species of Paurocephala
are not considered to be congeneric with the Old World species and will be
transferred to Diclidophlebia. Two South African species, P. bicarinata and P.
hottentotti, are removed from Paurocephala and have to be accommodated in a
new genus in the Diaphorininae. Thus Paurocephala is an Old World genus with
nine Afrotropical and 42 Indo-Australian described species. Keys for the identification
of adults and fifth instar larvae are provided. All 51 named species are
diagnosed and illustrated, and information is given on distribution and host
plants. Based on two cladistic analyses, one using adult characters only, and one
using both adult and larval characters, four monophyletic species groups are
recognized. In both analyses a basal group of 10 species, the brevicephala-group,
forms the sister group to all other Paurocephala spp. The Afrotropical species
are monophyletic and, together with one Oriental species constitute the gossypiigroup.
In the analysis with adult characters only, the gossypii-group is the sister
taxon of the kleinhofiae-group and, both together, are the sister group of the
psylloptera-group, the largest species group with 27 species. In the analysis of
adult and larval characters, the relationships between the last three species groups
are not resolved. The result of the phylogenetic analysis confirms the synonymy
of the subgenus Thoracocorna with Paurocephala. Known host plants of
Paurocephala spp. belong to the Malvifiorae with the exception of the Afrotropical
P. insolita which develops on Theifiorae (Theales, Clusiaceae). The brevicephala-,
kleinhofiae- and gossypii-groups are associated with hosts of the order Malvales
(Malvaceae and Sterculiaceae), whereas the psylloptera-group is with Urticales
(Urticaceae, Moraceae and Ulmaceae).peer-reviewe
Psylloidea (Insecta : Hemiptera) of the Arabian Peninsula
The jumping plant-louse fauna of the Arabian Peninsula is reviewed based on published records and material from
Bahrain, Kuwait, Oman, Saudi Arabia, the United Arab Emirates and Yemen, the latter being particularly rich. Fifty-two species,
nine of which remain unnamed, of 19 genera are recorded. Ten species are described as new, one species is synonymised and two
new combinations are proposed. Keys are provided for the identification of the adults and, where known, of the fifth instar
larvae. Diaphorina is the most species-rich genus followed by Acizzia, both being widely distributed in the Old World. The
Fabaceae bear the largest number of psylloids followed by Chenopodiaceae and Tamaricaceae.peer-reviewe

Preliminary check list of Central European jumping plant-lice (Insecta,Hemiptera, Psylloidea) with host plant data. — Based on collections and, to a certainextent, literature records, a check list of Central European psylloids is compiled,containing 4 families, 28 genera and 189 species. The aim of the list is to present amodern classification and correct nomenclature, and provide information on hostplants
The plant-louse Leuronota calycophylli sp. n. (Homoptera, Psylloidea), a pest on the timber species Calycophyllum spruceanum (Rubiaceae) in Peru
Leuronota calycophylli sp. n. attacks experimental plantations of the high-quality timber Calycophyllum spruceanum in Peru. Adults, larvae and the damage on the host are described and illustrated. Adults differ from other congeners in the absence of genal processes and in the structure of the genitalia. The host of L. calycophylli is unusual for psylloids: rubiacious hosts are otherwise known only from the four members of the Palaearctic Trioza galii Förster group and the Taiwanese Synpsylla wendlandiae Yan
Jumping plant-lice of Socotra Island (Hemiptera: Psylloidea)
The jumping plant-lice (Hemiptera: Sternorrhyncha: Psylloidea) of the island of Socotra (Yemen) are reviewed. A total of eight species are recorded, six of them for the first time from Socotra. Four species are described as new: Colposcenia dioscoridis sp. nov. (Aphalaridae), Diaphorina caliginosa sp. nov., D. hagherensis sp. nov. (both Liviidae: Euphyllurinae), and Pauropsylla jarmilarum sp. nov. (Triozidae). Males are described for the first time for Diaphorina elegans Burckhardt & Mifsud, 1998 and immatures for Pseudophacopteron verrucifrons Burckhardt & Harten, 2006 (Phacopteronidae). Two additional species, Cacopsylla sp. (Psyllidae) and Diaphorina sp., remain formally undescribed. Host plant, biological and distributional data (if available) are provided for each species and a key for identification of adults is supplemented. The jumping plant-louse fauna of Socotra is briefly discussed from a biogeographical viewpoint.ÄŚlánek pĹ™edstavuje pĹ™ehled fauny mer (Hemiptera: Psylloidea) ostrova Sokotra (Jemen).

Revision of the East Asian Plagiophorus hispidus species group (Coleoptera: Staphylinidae, Pselaphinae, Cyathigerini)
The hispidus species group is formed for four new species from East Asia of the genus Plagiophorus Motschulsky: P. hispidus sp. nov., P. hlavaci sp. nov., P. serratus sp. nov., and P. grandoculatus sp. nov. Uncoated specimens were examined using field-emission scanning electron microscopy, and micrographs of the holotypes are presented. Keys to the species groups of the genus occurring in East Asia and to the species of the hispidus group are given. The hispidus group is probably monophyletic, having peculiar spinous setae on the male metasternum. The chaetotaxy of the labrum and clypeus is useful for distinguishing species of Plagiophoru
First record of the Australian genus Platyobria Taylor, 1987 from Europe and P. biemani sp. nov. as a potential pest of Eucalyptus (Myrtaceae) (Hemiptera: Psylloidea)
Platyobria biemani sp. nov. (Aphalaridae, Spondyliaspidinae) is described from the island of Lesbos (Greece) based on a series of adult specimens which were collected on a long-leaved Eucalyptus species. This is a likely host as immatures of three of the nine previously known species of Platyobria Taylor, 1987 develop on young succulent terminal branchlets or leaves of eucalypts. This is the first time that Platyobria is recorded from outside Australia from where the new species probably originates. Whereas Platyobria species do not seem to affect their hosts significantly in Australia, there is a potential that in a new environment lacking specific parasitoids, P. biemani sp. nov. may become a pest of eucalypts
