Taxonomy

Polydacrys was described for the first time by Carl Johan Schönherr in 1834 (p. 130). [4] It was previously considered a member of the Tanymecini. [5]

There is a key to the Central American species of Polydacrys in Champion (1911: 217). [6]

Description

Members of Polydacrys are small (~6 to 12 mm) and can be recognized by their nasal plate, which is triangular, large, glabrous, shiny, and elevated from the surface of the rostrum. [5] In addition, their mandibular scars are projected from the surface of the mandible.

Distribution

Members of Polydacrys range from Texas through Bolivia and are particularly well-represented across the Caribbean. [1]

Species

These eight species belong to the genus Polydacrys [2] [3] :
