Improved tribal delimitation of the subfamily Dictyopharinae and description of new genera and new species (Homoptera,Fulgoroidea, Dictyopharidae)

Ten new genera, five new subgenera, and five new species are described in the family Dictyopharidae. Three generic names are synonymized. A new name is proposed for the generic homonym. Dictyophara kazeruna Dlabola is transferred to the genus Callodictya Melichar. The genus Sinodictya Matsumura, with the type species Sinodictya tukana Matsumura, is redescribed. A new key to the tribes of the subfamily Dictyopharinae is given. The composition and characters of the tribes Taosini and Lappidini are revised. All the genera of the subfamily Dictyopharinae are listed according to their tribal position. New records are given for some interesting species.     

A new genus of Dictyopharidae (Homoptera) from Chile

Chondrophana gen. n. with the type species Cixius gayi Spinola, 1852 (= Chondrodera chilensis Melichar, 1912, syn. n.) is described from Chile. The new genus differs from Chondrodera Melichar in a short head, fully developed intermedial carinae on the metope (clearly not reaching the clypeus in Chondrodera), in the presence of granules on the humeral and pectoral areas of the prothorax and also on the lateral lobes of the metope from the apical callus to the clypeus (in Ch. granicollis, granules and also the intermedial carinae in the lower half of the metope are absent), in multidentate apices of the 1st and 2nd segment of the hind tarsus, in a petiolate ScRM, and in the pterostigma closing the anteroradial area.     

A new genus and species of Dictyopharidae (Homoptera) from Rovno and Baltic amber based on nymphs

Alicodoxa rasnitsynigen. et sp. n. (Dictyopharinae: Orthopagini) is described based on a nymph from Rovno amber; it also occurs in Baltic amber. A small additional wax plate dorsal to the large wax plate of abdominal tergites VI-VIII is first reported in this and other genera of Dictyopharidae. A lectotype is designated for Pseudophana reticulata Germar & Berendt, 1856 transferred to Protepiptera (Achilidae): Protepiptera reticulata (Germar & Berendt, 1856), comb. n.     

Two new species of the genus Philaenus (Homoptera, Aphrophoridae) from Iran

Two new species of Philaenus from Iran are described. Philaenus elbursianus sp. n. belongs to the Ph. signatus species group from the nominotypical subgenus. Philaenus iranicus sp. n. differs considerably from all the known representatives of the genus and was separated in a new subgenus Gyrurus subgen. n. The occurrence of this highly peculiar species in Iran may indicate that the center of origin of the genus Philaenus lies in this territory and not in the Mediterranean region as it was considered before.

A new species of the planthopper genus <Emphasis Type="Italic">Nymphorgerius</Emphasis> Oshanin (Homoptera,Dictyopharidae) from Iran

A new species of Nymphorgerius Oshanin, N. rostratus sp. n., is described from Iran (Gilan Province).     

A review of Rheocricotopus (Psilocricotopus) chalybeatus species group from China,with the description of three new species (Diptera,Chironomidae)

The Rheocricotopus (Psilocricotopus) chalybeatus species group from China is reviewed. Three new species, R. (P.) brochus sp. n., R. (P.) rotundus sp. n. and R. (P.) serratus sp. n. are described as adult males. R. (P.) imperfectus Makarchenko & Makarchenko, 2005, R. (P.) robacki (Beck & Beck, 1964) and R. (P.) valgus Chaudhuri & Sinharay, 1983 are recorded from China for the first time and annotated. The diagnosis for the species group is emended and a key to adult males of the species group in China is presented.

A new citrus-feeding psyllid from the Comoro Islands, with a review of the Diaphorina amoena species group (Homoptera)

ABSTRACT. Analysis of host plant data for the seventy-one species of Diaphorina shows the genus to be unusually polyphagous, the species developing on eighteen families of dicotyledonous angiosperms. Apart from the common Asian citrus pest, Diaphorina citri , a second citrus-feeding species is described and discussed. This species belongs to the amoena species-group which is defined and a key to nine of the ten included species is given. Seven new species are described: flavipennis sp.n. and nigripennis sp.n. from East Africa on Strychnos usambarensis; huila sp.n. from Angola on Ptaeroxylon obliquum; turned sp.n., from South Africa (host unknown); orantimina sp.n. from Madagascar (host unknown); auberti sp.n. from Comoro Islands on citrus trees; and bispinulata sp.n. from Madagascar (host unknown).     

Identification of Planococcus citri (Homoptera: Pseudococcidae) and the description of a new species

Planococcus pacificus sp.n. is described from the South Pacific, Australia and South East Asia. P.citricus is synonymized with P.citri. A key and illustrations are given to separate the species discussed from each other and from the similar P.ficus group.

Two new genera of the family Derbidae from the new world,with description of recent and an extinct miocene new species (Homoptera,Fulgoroidea)

Two new species of the family Derbidae are described. Anticedusa gen. n. (tribe Cedusini) includes the recent A. loisae sp. n. (type species) from Costa Rica and A. dominicana sp. n. from the Miocene Dominican amber. Cedochrusa gen. n. (type species Cedusa quixoa Kramer from Panama) of the tribe Cedochreini also contains a new species, Cedochrusa luculenta sp. n. from Costa Rica. A new subtribe Eocenchreina subtrib. n. comprising genera Eocenchrea Muir, Melusa Em., and Anticedusa gen. n. is erected for Cedusini with the achilid venation of the clavus.     

A review of Sulcospira (Gastropoda: Pachychilidae) from China,with description of two new species

ABSTRACT

A revision of Chinese freshwater Sulcospira gastropods is presented here based on analysis of the morphological characteristics and partial sequences of the mitochondrial genes 16S rRNA and cytochrome c oxidase subunit I (COI). A total of three species was reported in China by earlier authors, including Sulcospira hainanensis, S. hunanensis and S. paludiformis. In this study, two new species of Sulcospira are described from Hunan Province and Guangxi Zhuang Autonomous Region based on morphological and molecular evidence.     

A new species of the genus Pibrocha Kirkaldy (Homoptera, Fulgoridae) with notes on the systematics of the subfamily Dichopterinae and with description of a new tribe

The second species is described in the genus Pibrocha Kirk., P. excelsa sp. n. from Thailand. The limits of the subfamily Dichopterinae are discussed, a new tribe Protachilini trib. n. erected for the South American monotypical genus Protachilus Fenn. is added to the tribes Dichopterinii, Cladodipterini, and Dorysarthrini. The composition of the families Fulgoridae and Dictyopharidae is also discussed. The origin of the articulated cephalic process in adult Dorysarthrini is hypothesized.
