Mazaceae, a family native to Asia and Oceania, is reported for the first time for the Colombian flora, with Mazus pumilus (Burm.f.) Steenis. This species is easily recognized by its herbaceous habit, leaves rosulate, elliptic to obovate cauline leaves, terminal, racemose inflorescences, bilabiate flowers with one 2-lobed upper lip and one 3-lobed lower lip, and fruit completely enclosed in the calyx. To date, this species has been recorded in three departments of Colombia, growing between the pavement. Additionally, we clarify the synonyms of this taxon.

Cryptotaenia japonica Hassk., a native species of Eastern Asia, is reported for the first time for the flora of Colombia. This taxon is easily recognized by its ternate leaves, rhombic leaflets, leaf margins irregularly serrate, cymose inflorescences, irregular rays and pedicels, white petals, cylindric stylopodium, erect stiles, and oblong fruits with five ribs. To date, this species has been recorded only in one locality in Cundinamarca department. A neotypification of C. japonica is proposed and keys for the genera of the tribe Oenantheae present in Colombia, and the species of Cryptotaenia s. str., are presented. Additionally, we report for the first time the family Empididae (Diptera) as floral visitor of this species.
