A new species of Ornithodoros (Acari: Argasidae) from desert areas of northern Chile por Muñoz-Leal, Sebastian, Venzal, José Manuel, González-Acuña, Daniel, Nava, Santiago, Lopes, Marcos G., Martins, Thiago F., Figueroa, Cecilia, Fernández, Nicolás, Labruna, Marcelo B.

“…Morphological and mitochondrial 16S rDNA sequence analyses were performed in order to compare this new soft tick species with other congeneric Neotropical representatives. Larvae of O. atacamensis are morphologically closely related to Ornithodoros talaje sensu stricto, Ornithodoros puertoricensis, Ornithodoros rioplatensis, Ornithodoros guaporensis and Ornithodoros hasei, all belonging to the O. talaje species group. …”

Importancia de la comunicación vibracional en el comportamiento reproductivo del salivazo de los pastos (Homoptera: Cercopidae) por López Machado, F.E., Peck, DC, Montoya Lerma, J.

“…This is new basic information on the family Cercopidae and especially for grassland spittlebug, the most important pest of neotropical forages. Considering the differences found in the calls of the two species, communication patterns could be used as a taxonomic tool, as has been used in other families.…”
