Overview

Comprehensive Description

Characteristics

The Cerapachyinae are characterized by the following derived traits (Bolton 2003):
  • Propodeal spiracle situated low down on the side of the sclerite and shifted posteriorly so that it is at or behind the midlength of the sclerite
  • Pygidium large, flattened dorsally; margins of flattened area armed laterally, posteriorly, or both with a series of short teeth or spines

Diagnostic Description

I have recently proposed to regard Forel's tribe " Cerapachys " as constituting an independent subfamily, the larvae of these ants being so different from those of the true Ponerinae and much more like the larvae of the Dorylinae.1 The limits of this new subfamily agree with those of Emery's section Prodorylinae, and Emery was probably right in contending that the Cerapachyinae are intermediate between the Dorylinae and Ponerinae.

 

The worker caste has a ponerine habitus, but is often long and slender. The postpetiole is separated from the third abdominal segment by a well-marked constriction, and as broad as the third segment. In the Indoaustralian Eusphinctus even the gastric segments are marked off from one another. A powerful sting is present.

 

The characters of the female in the various genera are peculiarly diverse. In some cases ( Phyracaces ), this caste is winged and not unlike the females of certain Ponerinae; in others (Parasyscia, Eusphinctus), the female is wingless and ergatomorphic; and, in still others (Acanthostichus, Nothosphinctus), the female is so much like the corresponding caste in the Dorylinae that it might be regarded as a dichthadiigyne. The male, on the other hand, though lacking the cerci, has a decidedly ponerine habitus. The male genitalia are completely retractile; the subgenital lamina deeply and broadly furcate.

 

The larvae are extremely like those of the Dorylinae; they are elongate and almost cylindrical, uniformly covered with short hairs, and without piliferous tubercles. The mandibles are small, narrow, pointed, and rather feebly chitinized, and I have failed to find a trophorhinium, or triturating organ in the mouth. Apparently the young are fed only on soft food. Moreover, the foraging habits at least of certain Australian Cerapachyinae (Phyracaces) resemble those of the Dorylinae.1

 

Dr. W. M. Mann has recently sent me specimens of his Cerapachys majusculus from Fiji, with several worker pupae which are enclosed in well-developed, brown cocoons. The Cerapachyniae seem, therefore, to agree with the Ponerinae in this character.

Cerapachyinae

The Cerapachyinae are a subfamily of ants of the Formicidae family, previously classified as a tribe of the Ponerinae subfamily. Modern phylogenetics has shown them to be in the dorylomorph clade along with the subfamily Leptanilloidinae and the army ant subfamilies Ecitoninae, Aenictinae, Aenictogitoninae, and Dorylinae.[2][3]

They possess spines on the pygidium and short, thick antennae. They lack dorsal thoracic structures. They are largely predators of other ant species, and many Cerapachyinae species display other army ant-like behaviors, including swarming and cyclic reproduction.[4] The roughly 200 species are distributed throughout the tropics.
