Ant species (Hymenoptera: Formicidae) of the Jornada

Entries based largely on collection records in W. MacKay and E. MacKay. 2002. The Ants of New Mexico. Edwin Mellen Press, NY and collections of B. Bestelmeyer. All entries represent collections within the Jornada Basin (JRN).

Important statistics

Species number at JRN: 74

Species number in North America: 751

Number of new species recently described from JRN: 4


JRN is an exceptionally species rich site (at about 10% of the entire North American fauna). This is probably due to the intensity of work here but also due to the geographic position of the area and the diversity of ant habitats.

Creosotebush-dominated (Larrea tridentata) communities, especially on the Summerford bajada, are the most species rich habitats in JRN. This plant community type is also the source of several newly described species.
