Eschatocerini

Figs. 211–213

This monotypic tribe may feel unsatisfactory for taxonomy, but its erection is based on phylogeny ( Ronquist et al. 2015). This unusual group can be readily collected when host plants are located; otherwise, the taxon is rarely collected.

Biology. Species are gall inducers on Prosopis spp. and Acacia spp. ( Fabaceae ) in South America.

Distribution. Arid regions of the Neotropics.

Relevant literature.Nieves-Aldrey and San Blas (2015) revised the tribe and described the biology in depth; Ronquist (1995b) and Ronquist et al. (2015) studied the phylogenetic placement of the group.

Classification.
