Austraphorura wahlgreni Bagnall, 1947 — Figs. 34-37

Austraphorura wahlgreni Bagnall, 1947
Figs. 34-37

The type specimen in the British Museum is badly mounted and crushed as mentioned by Bagnall in his original description. In my opinion a new genus and species should never have been accepted into the literature let alone described from a single crushed specimen. Nevertheless, sufficient of the characters are visible to validate it and to permit the preparation of the accompanying figures. The genus is characterised by the large, stout, rather blade-like, transversely directed sense rod of SO Ant III. This overlies a chitinous fold with a pair of minute sense clubs. A further sense rod lies somewhat removed and below the whole SO with five long guard setae as in Fig. 34. The PAO has 18 detached vesicles as shown in Fig. 36.

Pseudocelli with 1 + 1 on antennal base and Abds IV and V. There may be more on other segments but because of the condition of the specimen they cannot be determined. The apex of Ant IV may have a small retractable sensory knob. Sensory setae of Ant IV could not be determined.

The foot with a stumpy vestigial unguiculus and basal seta, no teeth (Fig. 35). The anal spines long, slightly curved, on papillae as in Fig. 37; the papillae about one third length of spines and the spines themselves subequal in length to hind claw.

Clothing of moderately long simple setae, longer posteriorly.
