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 Tico (Hemiptera: Auchenorrhyncha: Derbidae) on palms in Costa Rica.

Tico is a small genus of planthopper comprised of four species primarily known from Costa Rica, with one species known from Trinidad and Venezuela. Recent survey work has documented multiple new species from palms and other broadleaf monocots in Costa Rica. Herein, a new species, Tico villablanca sp. n., is described from palms in the Los Angeles cloud forest, Costa Rica. Novel molecular data for the 18S rRNA gene and cytochrome c oxidase subunit I (COI) gene is provided for the new species and supplements morphological support for placement in the genus Tico. An updated key is provided for the species of Tico.
