Abstract

Enchenopa Amyot & Serville, 1843 is a diverse treehopper genus widespread across the New World. We describe two new Enchenopa species from northwest Ecuador: Enchenopa gennyaesp. nov. from urban forest remnants at the foothills of the Andes cordillera and Enchenopa chocoandinasp. nov. from secondary montane forests. Enchenopa gennyaesp. nov. is placed in the E. biplaga species group and is distinguished by the sexual dimorphism of the pronotal horn and lateral carina shape, the straight metopidium, 2–4 accessory carinae and the whitish dorsal spot and subapical band. Enchenopa chocoandinasp. nov. belongs to the E. andina species group and is diagnosed by its reddish central carina and posterior pronotal process apex, presence of an obtuse projection rather than an anterior horn, three or four irregular accessory carinae, and apical amber forewing patch. Illustrations, notes on natural history, and keys to species of the E. biplaga and E. andina species groups are also provided.
