It is demonstrated that Pharaxonotha beetles are effective pollinators of Zamia incognita and that wind does not play any role as pollen vector, and it is suggested that pollination droplets on the micropyles would be a reward to pollinators.
Description and phylogeny of a new Neotropical genus of Acalyptini (Coleoptera: Curculionidae: Curculioninae) associated with the staminodes of Cyclanthaceae
The interspecific homogeneity in external morphology, coupled with marked differences in genital traits and an apparent absence of narrow geographical ranges mediated by either host plants and/or biogeographical factors, jointly suggest that the diversification of Azotoctla is a relatively recent phenomenon and driven strongly by sexual selection.

Contribution to the taxonomy of the family Membracidae Rafinesque (Hemiptera: Auchenorrhyncha) in Colombia.
Study of the literature and 3744 specimens deposited in ten colections in Colombia, as well as non-systematic collections and field observations done in Colombia between 2011 and 2014, led to record 116 genera and 474 species grouped in 9 subfamilies and 23 tribes, distributed in 24 departments.

Methyl acetate is highly volatile and it is hypothesize its efficacy relies on profuse emission by the inflorescences of A. phalerata, as specialized pollinating insects respond to high concentrations of the attractant, perhaps before odor plumes rapidly disperse.
Parandrinae (Coleoptera: Cerambycidae) from Colombia
The Parandrinae are a Cerambycidae subfamily with 63 described species, from which 45 occur in America, and 12 species are reported, ten of them from the specimens examined and two from reports in the literature.
