New Species of the Planthopper Genus Parkana (Hemiptera: Fulgoroidea: Delphacidae) from Mesoamerica
Transactions of the American Entomological Society
Six new species from Mesoamerica are described and illustrated into the formerly monotypic genus Parkana. These species are segregated into 3 subgenera, Parkana s.s. (bearing a large dorsal process on the aedeagus) consisting of 5 species, and a single species each in Furcoparca new subgenus (with the median processes of the pygofer formed into a large forked process), and Litoparca new subgenus (lacking both features, genitalia relatively simple, aedeagus bearing lateral teeth). The new species are P. (P.) mirasol, P. (P.) nigra, P. (P.) pallida, P. (P.) tres, P. (F.) chico (all from Mexico, except P. nigra also from Guatemala), and P. (L.) costa (Costa Rica). Keys are provided to subgenus and species. Parkana was previously known only from the type species (P. alata) from western United States. The diversity of Mesoamerican delphacid species is briefly discussed.
Astatometopon gen. nov. is described to accommodate A. sakakiba-rai sp. nov., a delphacid planthopper distributed in the Nahuelbuta and Andes mountain ranges in the central and south central zones of Chile. The new taxon is placed into Delphacini but it presents some unusual features for the tribe, such as a strongly asymmetrical phallus with a porrect process arising from base, the absence of teeth on the hind margin of calcar, and an exceptional variation in carination of the eumetope. Resumen. Astatometopon gen. nov. es descrito para acomodar a A. sakakibarai sp. nov., un delfácido distribuido en las cordilleras de Nahuelbuta y los Andes en las zonas centro y centro sur de Chile. El taxón es clasifi cado en Delphacini pero presenta características inusuales para la tribu, como un falo fuertemente asimétrico con un proceso porrecto erigido desde la base, la ausencia de dientes en el margen posterior del calcar, y una variación excepcional en la carenación de la eumetopa.
New distributional records of Delphacidae (Hemiptera: Fulgoroidea) from Chile
Chionomus haywardi (Muir, 1929) (previously known for Argentina and Uruguay), Syndelphax dissipatus (Muir, 1926) (previously known for Ecuador, Brazil, Panamá and Costa Rica) and Dicranotropis bipectinata Muir, 1926 (previously known for Ecuador) are recorded for the first time from Chile. Additionally, the known distribution range of Delphacodes darwini Muir, 1929 (previously known only from Los Lagos region) is expanded up to Coquimbo region and Delphacodes kuscheli Fennah, 1955 (previously known from Juan Fernández Islands, Argentina and Uruguay) is recorded for first time from continental Chile. Photographs and diagnostic characters of the males are provided. Resumen: Nuevos registros de distribución de Delphacidae (Hemiptera: Fulgoroidea) de Chile. Se registran por primera vez para Chile las especies Chionomus haywardi (Muir, 1929) (previamente conocida de Argentina y Uruguay), Syndelphax dissipatus (Muir, 1926) (previamente conocida de Ecuador, Brasil, Panamá y Costa Rica) y Dicranotropis bipectinata Muir, 1926 (previamente conocida de Ecuador). Adicionalmente, el rango de distribución conocido de Delphacodes darwini Muir, 1929 (previamente conocida sólo de la región de Los Lagos) se amplía hasta la región de Coquimbo y Delphacodes kuscheli Fennah, 1955 (previamente conocida del archipiélago de Juan Fernández, Argentina y Uruguay) se registra por primera vez para Chile continental. Se proporcionan fotografías y caracteres diagnósticos de los machos.

The new delphacid genus Akemetopon gen. n. (Delphacinae: Delphacini) is described and illustrated with 3 new species from Arizona and Mexico: Akemetopon inornatum sp. n., A. politum sp. n., and A. ainigma sp. n. A key to species is provided. The barcoding portion of the mitochondrial gene Cytochrome Oxidase I (COI) was sequenced for A. politum sp. n. A maximum likelihood analysis places this genus in the basal Delphacini.
A new genus and species of Saccharosydnini (Hemiptera: Fulgoromorpha: Delphacidae) from Argentina
Zootaxa, 2011
One new delphacid genus and species, Lacertina australis Remes Lenicov & Rossi Batiz, gen. et sp. nov. (Hemiptera: Fulgoromorpha: Delphacidae: Saccharosydnini), is described and illustrated from Argentina with distribution data and host plants data provided. The new genus is easily distinguished from all other genera of the Neotropical Saccharosydnini by being strongly dorsoventrally flattened with a wide vertex projecting 2/3 of its length beyond the eyes and the presence of two submedian carinae on frons. An identification key to the genera of Saccharosydnini is provided.
A review of New World Malaxa (Hemiptera: Fulgoroidea: Delphacidae)
Zootaxa, 2018
The New World species attributed to the genus Malaxa Melichar (Hemiptera: Fulgoroidea: Delphacidae) are reviewed with special reference to the type species Malaxa acutipennis from the Philippines. We provide an amended diagnosis for Malaxa acutipennis contrasted with the genus delineation presented for Chinese Malaxa, most recently by Hou et al. (2013). We find Malaxa to be an Old World genus and segregate New World species into two new genera, Lamaxa and Xalama, diagnosed most readily by proportions of the antennae and features of the terminalia. Both Lamaxa and Xalama are uncommonly encountered. Lamaxa is distributed widely through the Neotropics, whereas Xalama is heretofore known only from Bolivia and Peru.
