New World legume-feeding psyllids of the genus Aphalaroida Crawford (Insecta: Homoptera: Psylloidea)

Aphalaroida comprises a compact group of nine species feeding on mimosoid legume host plants in the southern USA and Central America. The species, acaciae Crawford, californica Tuthill, inermis Crawford, lysilomae sp. n., masonici (Caldwell), pithecolobia Crawford, prosopis Crawford, rauca sp. n. and spinifera Crawford, are keyed out and data are given on host plants and distributions. Characters previously used to separate species are unreliable, and there is strong evidence to suggest that some species are polymorphic with respect to fore wing pattern. This had led to much confusion, with type series often containing mixtures of species. Fore wing shape, the form of male and female terminalia, the shape of the genae and the presence/distribution of glandular hairs are the most reliable diagnostic characters.     

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. setifera 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 gossypii group. 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 Malviflorae with the exception of the Afrotropical P. insolita which develops on Theiflorae (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).     

Systematics and biology of the Rhinocolinae (Homoptera: Psylloidea)

Based on a cladistic analysis, the subfamily Rhinocolinae is redefined to comprise 13 genera and 39 species, of which two genera and eight species remain unnamed. Four new genera and 14 new species are described; one subfamily and one genus are synonymized, and two species are recombined; one lectotype is designated. The subfamily is divided into two groups, one with a Gondwanan distribution comprising four genera in Australia, New Zealand, South America and Africa, and another with Laurasian distribution in the Palaeotropics, the Western Palaerctic and North America comprising nine genera. Twenty-one species develop on host plants in the Rutales, three on Asteraceae, three on Cistaceae and one on Zygophyllaceae. The genus Pistacia (Anacardiaceae) in particular hosts six species whose biology is discussed.     

Horizontal distribution of psammophilic ciliates in fine sediments of the Chichester Harbour area

The distribution of 28 species of psammophilic ciliates isolated from the fine sands of Chichester harbour was correlated with gradients of ecological factors running horizontally in a granulometrically uniform sediment. Six sampling stations were situated on a single transect that ran parallel to the shoreline for a distance of 987 metres. Sediment analysis indicated that the substrate was homogeneous with respect to grain size but detrital material increased from 0·01% to 1·15% in a continuous gradient around the headland. Gymnostome and hypotrich ciliates dominated the samples. Eight species were new records for the British coast, thus bringing the total for Britain to 178; each species displayed its own distribution pattern along the transect. Some species were encountered at every station while others were restricted to a short length of coastline. Species diversity was greatest at stations adjacent to saltmarshes where interactions between detrital deposition and wave exposure appeared particularly favorable for the development of the microfauna. The existence of horizontal distributions running parallel to the shoreline taken together with previous knowledge of species diversity in both horizontal and vertical planes, gives a more complete picture of the three dimensional distribution of a population of psammophilic ciliates inhabiting a marine beach habitat.     

Gall-inducing jumping plant-lice of the Neotropical genus Baccharopelma (Hemiptera,Psylloidea) associated with Baccharis (Asteraceae)

The junior homonym Burckhardtia Brown and Hodkinson nec Frech is replaced by Hodkinsonia nom. n. The introduction of the two generic replacement names necessitates two new combinations. Four species are described as new. Keys for the identification of adults and the last instar larva are provided along with species diagnoses and illustrations of taxonomically relevant structures. The galls and known biological features are briefly discussed for each species and the phylogenetic relationships among the species are analysed. Baccharopelma spp. are monophagous on Baccharis spp. (Asteraceae) on which they induce galls. The temperate South American genus has one species restricted to Chile, three to Brazil and one occurring in Argentina, Brazil and Paraguay.     

On systematic relations of Oomorphus concolor (Sturm) Col., Chrysomelidae), with descriptions of its larva and of an aberrant Cryptocephaline larva from Australia

The phylogenetic significance of morphological characters used to diagnose Bactericera, Rhinopsylla, Paratrioza, Allotrioza, Klimaszewskiella, Eubactericera, Phylloplecta and Sinitrioza is examined. There is no evidence that the genera or subgenera, in any of their present or past definitions, constitute natural units. The six former together, however, form a monophyletic group, defined by a combination of adult, larval and egg characters. Phylloplecta and Sinitrioza, which share similar adult characters with Bactericera, differ in the larval and egg morphology. The following new synonymies are established: Bactericera (=Rhinopsylla pro parte, = Paratrioza, = Allotrioza, = Klimaszewskiella, = Eubactericera pro parte) and Phylloplecta (= Sinitrioza). A list of the 121 species included in Bacerticera is provided and 75 new combinations are introduced (60 in Bactericera, 4 in Phylloplecta, 9 in Trioza and 1 in Kuwayama). Bactericera equisetifolii sp. n. and B. vellae sp. n. are described from Israel and Spain respectively, and B. loginovae, B. perrisii and B. rossica are redescribed. The following new species level synonymies are proposed: B. perrisii (= B. maritima) and B. gobica (= P. sinica, = P turcamanica). Variation of genal cone length in B. kratochvili is discussed and the presence of two biological races is noted in B. modesta. Keys are provided for the adults of the European species associated with Salix, and the last instar larvae of the West palaerctic species; the latter are also illustrated. Information on life cycles and host plants is summarised and briefly discussed. Differences in the hindwing venation, which were recently used to erect the families Rhinopsyllidae and Rhinocolidae are shown to be trivial. The two families are therefore synonymised with the Triozidae and Psyllidae respectively.

The generic affiliation of Japanese species of the subfamily Psyllinae (Hemiptera: Psyllidae) with a revised checklist

The generic affiliations of all the Japanese species of the psyllid subfamily Psyllinae are re-examined under the current generic recognition of the subfamily based mainly on adult morphological characters. Twenty-two species of the genus Psylla Geoffroy are newly combined with the genus Cacopsylla Ossiannilsson. Psylla wulinensis Yang and Aphalara akebiae Shinji are newly synonymized with Psylla multipunctata Miyatake and Cacopsylla hakonensis (Kuwayama), respectively. In addition, Cacopsylla toddaliae (Yang) is newly recorded from Japan. In all, 62 species of the Japanese Psyllinae are recognized and classified into three genera Psylla, Cacopsylla and Chamaepsylla Ossiannilsson, which include 11, 50 and one species, respectively. A key to Japanese psylline genera and a revised checklist of all the Japanese species of Psyllinae are presented with their distribution and host plant information and also with their synonymies.     

The Nearctic Psylloidea (Insecta: Homoptera): an annotated check list

The 302 species of jumping plant lice (Insecta: Homoptera: Psylloidea) recorded from the Nearctic zoogeographical region are listed under their respective genera. Information is given on synonymy, host plants and distribution; and the taxonomic position of problematical species is discussed. A list of host-plants and their associated psyllids in also included.     

Aedeagal musculature in phytophaga (Coleoptera)

Summary

Three species of Cerambycidae and three of Chrysomelidae have been studied from the standpoint of the aedeagal musculature. A brief reference to this part of the anatomy in Bruchidae has also been made. On the basis of the present observations and earlier publications in this area a basic plan for the aedeagal musculature in Phytophaga could be inferred. Some major and minor modifications of the basic plan have been pointed out. It has also been inferred that ‘retournement’ of the aedeagus is a rule along Phytophaga.
