Melanetettix gen. nov. is described from Melanesia for 22 new species of leafhoppers. The new species fall into four groups. New species described are M. bicolor, M. bifidus, M. capitatus, M. curvatus, M. delmoi, M. elongatus, M. maai, M. marginatus, M. ocellatus, M. pallidus, M. rhamphodes, M. roseus, M. semeraroae, M. sinuatus, M. aculeus, M. bifurcatus, M. truncatus, M. clavatus, M. ensiferus, M. nielsoni, M. rotundatus and M. alatus. An identification key to the new species is provided along with discussion of the affinities of Melanetettix, which is close to Scaphoideus Uhler.

A new genus and six new species of ground-dwelling leafhoppers from Chile and New Zealand (Hemiptera: Cicadomorpha: Myerslopiidae)

A new genus, Mapuchea gen. nov. from Chile, is described with Myerslopia chilensis NIELSON, 1996 (type species) and two new species (Mapuchea burckhardti sp. nov. and Mapuchea hamiltoni sp. nov.). The nymphs of an unidentfied species of Mapuchea are also described. Four new species of the New Zealand genus Myerslopia Ev. (M. rakiuraensis sp. nov., M. whakatipuensis sp. nov., M. tawhai sp. nov. and M. tearohai) are described. Additional data on the distribution of some species of the genus Pemmation HMLT. are also presented.

New species of Neotropical leafhoppers in the tribe Youngolidiini with a revised key to species (Homoptera: Cicadellidae: Coelidiinae)

AbstractNine new species of leafhoppers in the tribe Youngolidiini are described and illustrated. These include Rikana aculeala; Pilosana stylata, P. gladia, P. cristata, P. hamata; Youngolidia hirsuta, Y delta, Y. paracrista, and Y. aviculifera. A revised key to species in the genera Rikana, Pilosana, and Youngolidia is also presented.

New species of Neotropical leafhoppers in the tribe Teruliini with a revised key to some species (Homoptera: Cicadellidae: Coelidiinae)

AbstractSeven new species in three genera are described and illustrated from the Neotropical region. New species include: Docalidia argutiae from Brazil, D. testa, D. acus, D. filamenta from Peru, D. lamina from Ecuador, Perulidia lobata from Ecuador and Stalolidia curta from Brazil. A revised key to species in the genera Perulidia and Stalolidia is also presented. Five species are briefly discussed and illustrated to show intraspecific variation in relation to geographic distribution.

A NEW SPECIES OF DRAECULACEPHALA (HOMOPTERA: CICADELLIDAE) FROM MANITOBA

AbstractA new species of leafhopper, Draeculacephala robinsoni, very similar to D. portola Ball, has been examined and found to be distinct from that species, on the bases of internal male genitalia and vertex angle.

A New Genus and New Species of Deltocephaline Leafhoppers from Canada and Alaska (Homoptera: Cicadellidae)

The following are descriptions of a new genus and two new species of leafhoppers allied to Streptanus Rib. and Macustus Rib. that have been found in the Subarctic of Alaska and northwest Canada, of a new species of Hardya Edw. from the same region, and of the two new species of Hebecephalus DeL. from the mountains of Western Canada.

A New Species of Scaphytopius (Cloanthanus), with a Key to the Canadian Species (Homoptera: Cicadellidae)

The following is a description of a new species of leafhopper from Eastern Canada of the subgenus Cloanthanus of the genus Scaphytopius. A key to the known Canadian species of Cloanthanus is included. Two of these species, angustatus (Osb.) and argutus DeL., do not appear to have been recorded previously for Canada. The key is based primarily on structures of the male genitalia, as these show the most reliable specific characters. External characters of colour, markings, and structure are often unreliable, because of the variation that occurs. There is occasionally some variation in the genitalic characters, notably in the degrees of curvature of the paraphyses, but the general shape of each structure is sufficiently constant to provide reliable specific characters. This subgenus, which was revised by Hepner (1947), is poorly represented in Canada, as the majority of the species have southerly distributions in North America. The common Canadian species is acutus (Say), followed by latus (Baker); the remaining species are more restricted in their ranges and distributions in Canada.

Two New Species of Dikraneura from Western Canada, with Notes on Other Species (Homoptera: Cicadellidae)

The following are descriptions of two new species of leafhoppers of the genus Dikraneura from Western Canada. Notes on other species found in that region are appended. Two of the latter, rubrala DeL. & C. and rufula Gill., have apparently not been recorded previously for Canada. Figures of the aedoeagi are provided, as this structure normally provides the only reliable specific characters and must be examined if specific identifications are required. The name Dikraneura is used here in the restricted sense, following Oman (1949), rather than in the broad sense of DeLong and Caldwell (1937), Beamer (1943), and others.

A New and Important Species of Leafhopper Injuring Apple in Ohio

A new species of leafhopper, Empoa malini , has been found causing decided losses on apple in central Ohio. It has been the most abundant species on apple during the past two years. It closely resembles E. rosae with which it has apparently been confused. The color is more yellow than E. rosae but the easiest method of distinguishing them is by the terminal processes on the oedagus.
