Biology

A. australis feeds on a range of soft-bodied arthropods and nests in logs above ground (Shattuck, 1999; Wheeler 1933)

In the SWBP, WA, nests of A. australis are not uncommon under logs and rocks. This is the Amblyopone most commonly encountered in the hills behind Perth.

Castes

Queen–worker dimorphism in body size is very pronounced in A. australis (Peeters & Molet 2010). Workers are polymorphic, and large individuals may be better adapted for digging galleries in rotten logs.

Amblyopone australis type material
Lectotype worker (Yoshimura & Fisher, 2012: 3) from Tasmania, Australia, Scheyer (misspelling of Schayer) (Berlin Museum für Naturkunde der Humboldt-Universität): 7228, CASENT0104575. Two specimens with same locality and collector information; one labeled ‘‘Type.’’ The original description of this species does not include detailed type information; however, Erichson mentions in the same paper that Schayer provided much material from Tasmania. Original labels on this specimen seem to have been replaced by new labels, and the collector on the new label is listed as ‘‘Scheyer,’’ a misspelling of Schayer, the collector’s name.

Amblyopone obscura type material
Syntype worker(s) and queen(s) from Australia (The Natural History Museum).

Amblyopone australis fortis type material
Syntype workers from Kuranda and Cairns, Queensland (Musee d'Histoire Naturelle Genève).

Amblyopone australis minor type material
Syntype workers, queen(s) and male(s) from Tamborine Mt. (as Mt. Tambourine), Queensland (1 worker in Australian National Insect Collection, location of other material uncertain).

Amblyopone australis foveolata type material
Syntype workers, queen and males from Denmark, Western Australia (2 workers, 1 queen and 3 males in Museum of Comparative Zoology).

Type Material

The following notes on F. Smith type specimens have been provided by Barry Bolton (details):

Amblyopone cephalotes

Holotype worker (presumed) in The Natural History Museum, mounted on card with a pupa. Labelled “Amblyopone cephalotes Smith. N. Zeal.” The specimen matches the original description but there is no datum label that proves it to be the true holotype. The original description states that the holotype was “collected by Mr Lawson at Auckland.”

Amblyopone obscura

One syntype queen in The Natural History Museum (syntype worker could not be found). Labelled “Australia,” and “A. obscura Sm. Type.”

Description

Karyotype

n = 24, 2n = 48 (Australia) (Imai et al., 1977).
