The tribe Dysoniini part VI: Phylogeny, biogeography and evolutionary trends of the lichen katydid genera (Orthoptera: Tettigoniidae: Phaneropterinae). Eleventh contribution to the suprageneric organization of Neotropical phaneropterines.

The tribe Dysoniini is widely distributed in the Neotropics, ranging from northeastern Mexico across Central and South America to northern Argentina. In the latter subcontinent it is most diverse. These tettigoniids are remarkable for their lichen- and bryophyte-mimicking camouflage and for having a particularly elevated vertex, which is unusual in the family Phaneropterinae.

Studies on chevron crickets: Contribution to the knowledge of Lutosinae/ini taxa (Orthoptera: Anostostomatidae).

In this contribution to the study of chevron crickets, we focus on several taxa of the subfamily/tribe Lutosinae/ini. Historical background was made on the classification of this group. Lutosa is redescribed, defining the generic and specific limits, thus providing a key for identifying the species based on males and another based on females.
