A new species of planthopper in the genus Anotia (Hemiptera: Auchenorrhyncha: Derbidae) from the Los Angeles cloud forest in Costa Rica.

Recent survey work in Costa Rica has resulted in the discovery of new species of derbid and cixiid planthoppers associated with palms. During this survey, one species belonging to the genus Anotia has been discovered and described, A. firebugia. A second species was collected while sweeping trailside vegetation in the Los Angeles cloud forest in Costa Rica and determined to represent a new species of Anotia. Herein, Anotia cerebro sp. n. is described and supplemental molecular data for the cytochrome c oxidase subunit I (COI), 18S rRNA gene and D9-D10 expansion region of the 28S rRNA gene are provided.

A new species of planthopper in the genus Haplaxius from Osa Peninsula in Costa Rica (Hemiptera: Fulgoroidea: Cixiidae).

Haplaxius is a large genus of New World cixiid planthoppers. The genus is of particular interest because Haplaxius crudus can transmit palm infecting phytoplasmas and the recent discovery of additional Haplaxius on palms during survey work highlights the need to fully understand the diversity of this genus on palms. Herein, a new species, Haplaxius cotinga sp. n., is described from the Osa Peninsula in Costa Rica. This species is most similar to H. deleter from southern Panama, from which it differs mostly by features of the male terminalia. Molecular data for the cytochrome c oxidase subunit I (COI), 18S rRNA, and histone 3 (H3) gene is provided and demonstrates supplemental support for placing the novel taxon in Haplaxius.

A new species of planthopper in the genus Agoo (Hemiptera: Fulgoroidea: Derbidae) from coquito palms (Astrocaryum alatum) in Costa Rica.

An ongoing survey to document planthopper diversity on palms (Arecaceae) is being conducted in Costa Rica. During these efforts a new species of derbid planthopper belonging to the genus Agoo was found on Astrocaryum alatum Loomis in the Heredia province at La Selva Biological Station and is described here as Agoo luzdenia Bahder Bartlett sp. n., bringing the genus to four described taxa-A. dahliana, A. luzdenia Bahder Bartlett sp. n., A rubrimarginata, and A. xavieri. Sequence data for the cytochrome c oxidase subunit I (COI) and 18S genes was generated for the novel taxon and strongly supports its placement in the genus Agoo.

A new genus and species of delphacid planthopper (Hemiptera: Fulgoroidea: Delphacidae) from Central America with a preliminary regional species list.

The new genus Ampliphax, assigned to the Delphacini, is described and illustrated with a single new species A. grandis from Costa Rica and Panama. Ampliphax grandis is a large species with a projected head. DNA barcode data suggest, among currently barcoded taxa, an affinity to the genus Bostaera. A checklist of the delphacid species from Costa Rica, Panama, and Nicaragua based on literature and specimen records is provided.
