Nomenclature

  • minutus. Dorymyrmex minutus Emery, 1895i: 15, fig. (w.) CHILE. Combination in D. (Conomyrma): Gallardo, 1916a: 43; in D. (Ammomyrma): Kusnezov, 1952g: 429; in Araucomyrmex: Snelling & Hunt, 1976: 100; in Dorymyrmex: Shattuck, 1992c: 85.

Description

La couleur varie: j'ai vu des exemplaires brun fond:, avec les mandibules, antennes et pattes plus ou moins roussatres; d'autres chatain clair, avec las appendices du corps plus pales.

Worker

Ressemble a premiere vue a un petit Dorymyrmex pyramicus Rog. par la forme du corselet, dont le metanotum porte une pointe fort proeminente: toutefois cette Fourmi est bien distincte de D. pyramicus et se rapproche davantage de Dorymyrmex tener Mayr, par la frange de tres longs poils qui descend de la partie posterieure du dessous de la tete; les palpes sont conformes comme chez D. tener. La tete est plus luisante que chez les autres Dorymyrmex, meme plus que chez les petits exemplaires de D. pyramicus de l' Amerique du Nord.

Long. 2 - 2 1/2 mm.

Type Information

Cordillere de Chillan, col. M. Germain.

Etymology

Referring to the small body size of the species relative to Dorymyrmex pyramicus, which Emery noted this ant resembles.
