The genus Parandes Muir, 1925 (Cixiinae, Andini) is recorded from China for the first time with two new species, Parandes circinatus Wang & Chen sp. nov. and Parandes fuscus Wang & Chen sp. nov. Color images for the adults of the two new species and line drawings for the genitalia are provided. A key is presented to separate all species within the genus.
The Australian genus of Eurybrachidae (Hemiptera, Fulgoromorpha) Kamabrachys gen. nov. is described to accommodate Platybrachys signata Distant, 1892 and Euronotobrachys plana Kirkaldy, 1906, the former being the type species. The new combinations Kamabrachys signata (Distant, 1892) gen. et comb. nov. and K. plana (Kirkaldy, 1906) gen. et comb. nov. are subsequently proposed. Ten new species are also included in the genus and described: K. andersoni gen. et sp. nov., K. brennani gen. et sp. nov., K. campbelli gen. et sp. nov., K. danielsi gen. et sp. nov., K. falcata gen. et sp. nov., K. fasciata gen. et sp. nov., K. pedemontana gen. et sp. nov., K. rieki gen. et sp. nov., K. v-carinatum gen. et sp. nov. and K. waineri gen. et sp. nov. The male and female genitalia of each species are illustrated and photographs of habitus, distribution maps, biological data and an identification key are provided. The mating behaviour of K. signata is described, illustrated and discussed. The genus Kamabrachys currently contains 12 species and is associated to trees in the family Myrtaceae.
A new species of the genus Pyrops Spinola, 1839 (Fulgoridae), P. buomvoi sp. nov., is described from Ca Na, Ninh Thuan Province in Central Vietnam. It is attributed to the candelaria group and compared with the other species of the genus. Pyrops lathburii (Kirby, 1818) is proposed as a senior synonym of P. astarte (Distant, 1914), transferred back to the candelaria group from the pyrrhorhynchus group, and recorded from Laos for the first time. The candelaria and pyrorhynchus groups are defined and commented on. Intraspecific variation in the colour of the hind wings is recorded for the first time in Pyrops condorinus (Lallemand, 1960). A checklist of the 12 Vietnamese species of Pyrops and an illustrated key which can also be used for Laos, Cambodia and Southern Continental China, are given. Pyrops buomvoi sp. nov. is the first new species of Pyrops discovered in Indochina for more than 50 years. Intraspecific colour variation in the species of Pyrops is briefly discussed.
Ninety percent of the Cixiidae of the Macaronesian archipelagos are endemic. Each archipelago has its own endemics reaching a total of 31 taxa. The Madeira archipelago comprises five species: Cixius madeirensis China, 1938, C. verticalis Noualhier, 1897, C. chaoensis China, 1938, Hyalesthes madeires Remane & Hoch, 1986 and H. portonoves Remane & Hoch, 1986. Good knowledge concerning taxonomy, habitat information and distribution are essential for the conservation of the biodiversity of this rich archipelago. However, due to intraspecific variation and incomplete descriptions, misidentifications of Madeira cixiids have been common. In this work, the taxonomy of this family is reviewed and ecological data based on material collected over more than forty years are presented. A new species, Cixius wollastoni sp. nov., is described. A new combination, Tachycixius chaoensis (China, 1938) comb. nov., is proposed, and a new record, Pentastiridius leporinus (Linnaeus, 1761), is reported. Lectotypes are designated for Tachycixius chaoensis and C. verticalis. The genital structures of the latter species are depicted for the first time. All species are diagnosed, described, photographed and illustrated, and an identification key for the family is provided. Thanks to this new information, Madeira together with Tenerife are the two Macaronesian islands with the highest number of endemic species of cixids.
The genus Parasogata Zhou, Yang & Chen, 2018 is here reported from India represented by the new species Parasogata sexpartita sp. nov. collected in a recent exploration and survey of delphacids from Nagaland in northeastern India. A second species of Eoeurysa Muir, 1913 from India, the new species Eoeurysa sagittaria sp. nov., was found in Rampur, Una, Himachal Pradesh. Both new species are described with illustrations, and a molecular identification is given with the mtCOI gene sequence. A modified key to species of the genera is also provided.
The Oriental genus of Eurybrachidae (Hemiptera, Fulgoromorpha) Purusha Distant, 1906 is reviewed and a key to the genera of Eurybrachini is given. Two new species, P. bellissima sp. nov. and P. vietnamica sp. nov. are described from Myanmar and North Vietnam, respectively. Purusha rubromaculata Distant, 1906 is proposed as a junior synonym of P. reversa (Hope, 1843). All species are illustrated, including all type specimens and the male genitalia for the first time. Distribution maps, identification key to species and biological data are provided. The sexual dimorphism in the genus is discussed. Five species are currently placed in Purusha.
A new species of the genus Birdantis Stål, 1863 (Hemiptera: Fulgoridae), B. bhaskarai sp. nov. from Larat Island (Tanimbar), is described. Birdantis collaris (Walker, 1870) stat. rev. and B. trilineata (Schmidt, 1926) stat. rev. are reinstated as valid species, respectively from status of subspecies and as junior synonym of B. delibuta Stål, 1863. These four species, as well as the other one previously described from the Maluku Islands, B. decens Stål, 1863, are illustrated from their type specimens. An identification key, a distribution map, illustrations of habitus and details of male genitalia are provided. The synonymy between Myrilla Distant, 1888 and Birdantis is formally reinstated and all species formerly placed in the subgenus Birdantis (Myrilla) are transferred to Birdantis sensu stricto. Birdantis is transferred to the subfamily Aphaeninae Blanchard, 1847 and now contains eighteen species distributed in Maluku (five species), New Guinea and neighbouring islands (ten species) and Australia
(three species).
The Afrotropical planthopper genus Centromeriana Melichar, 1912 (Hemiptera, Fulgoromorpha, Dictyopharidae, Dictyopharinae, Orthopagini) is revised. Four species are included: C. jocosa (Gerstaecker, 1895) (the type species, with confirmed records from Cameroon, Equatorial Guinea and Gabon), C. lindbergae sp. nov. (described from Sierra Leone), C. rhinoceros sp. nov. (described from Togo) and C. simplex Melichar, 1912 (so far only known from Equatorial Guinea, Bioko island). Lectotypes are designated for C. jocosa and C. simplex and both species are redescribed including habitus photographs and detailed illustrations of the male and female genitalia which are published for the first time. A key for identification of the species of Centromeriana is provided. As far as known, the genus is endemic to the (Guineo-)Congolian region of western Africa.
Two new species of the genus Gergithoides Schumacher, 1915 (Issinae, Hemisphaeriini), G. gnezdilovi sp. nov. from Bidoup-Nui Ba National Park in Central Vietnam and G. nui sp. nov. from Pia-Oac National Park in North Vietnam, are described. These are the only species of the genus formally recorded from Vietnam to date. Habitus, details and male genitalia are illustrated and a distribution map is provided. Four females representing three or four additional species, known from females only, are mentioned and illustrated. Taxonomic and biogeographical updates based on a thorough review of the literature are proposed and discussed for G. carinatifrons Schumacher, 1915, G. rugulosus (Melichar, 1906) and G. undulatus Wang & Che, 2003.
