New species of Leafhopper from Brazil.

Leafhoppers (Cicadellidae) are small members of the True-bug order, Hemiptera, with hind legs modified for jumping. They feed on plants by draining the sap with modified mouthparts, leading many species to be regarded as agricultural pests. Immature leafhoppers (Nymphs) are similar to the adults, there is no metamorphosis on reaching maturity. The group are extremely successful, with over 20 000 described species, many of which are extremely widespread, and a fossil record dating back to the Early Cretaceous.

In a paper published in the journal ZooKeys on 15 November 2012, Adenomar Neves de Carvalho of the Instituto de Biodiversidade e Florestas at the Universidade Federal do Oeste do ParĂ¡, describes a new species of Leafhopper from the Roraima and Amazonas States of northern Brazil.

The new species is placed in the genus Paraportanus, which is widespread in Brazil and Peru, and given the specific name longispinus, meaning 'long-spines', a reference to the male reproductive organ. Paraportanus longispinus is a 5 mm yellow and brown Leafhopper.

  1. When I found Dr. OSOFO I was in desperate need of bringing my ex lover back. He left me for another man. It happened so fast and I had no say in the situation at all. He just dumped me after 3 years with no explanation. I contact Dr.OSOFO through his website and He told me me what i need to do before he can help me and i did what he told me to, after i provided what he wanted, he cast a love spell to help us get back together. Shortlay after he did his spell, my boyfriend started texting me again and felt horrible for what  he just put me through. He said that I was the most important person in his life and he knows that now. We moved in together and he was more open to me than before and then he started spending more time with me  than before. Ever since Dr. OSOFO helped me, my partner is very stable, faithful and closer to me than before. I highly recommends Dr. OSOFO to anyone in need of help.
