Distribution

This species has previously been recorded fromnorthern New South Wales and from scattered localities in northern Queensland (Cape York Peninsula), central Australia (Glen Helen area) and northern Western Australia (King Leopold Ranges) (Pokryszko 1996[3]). In addition, it is now recorded from the Hamersley Ranges, the Burrup Peninsula and a few isolated sites from approximately 100 km SSE of Port Hedland in the Pilbara region (Figure 3).

Comparative morphology

Gastrocopta hedleyi shellsare slightly smaller (shorter) than those of other Gastrocopta species (excluding Gastrocopta sp. CW1) recorded from the Pilbara. They typically have (1) a large, usually rounded (sometimes acute) columellar tooth that is drooping at the anterior end (2) a high, strongly convergent upper palatal tooth (3) a long, high, strongly twisted parietoangular tooth that usually comes in close proximity to the upper palatal tooth (4) a prominent infraparietal tooth that is sometimes prolonged as thin ridge on parietal wall (5) often a strong basal tooth (6) very occasionally with a weak interpalatal tooth.
Some Gastrocopta hedleyi shells (particularly more elongate specimens) can be difficult to separate from the ovate form of Gastrocopta mussoni but (1) are smaller (slender) when sympatric (2) have a less rounded body whorl (3) have a more strongly sigmoid lower palatal tooth (4) have a larger upper palatal tooth that is usually strongly convergent with the lower palatal (5) have a longer, more strongly twisted parietoangular tooth (6) have a larger, more rounded columellar tooth that is usually drooping at the anterior end .
The cylindrical form of Gastrocopta mussoni is also very similar to Gastrocopta hedleyi but (1) has a lower, shorter and less twisted parietoangular tooth (usually at 45o angle in apertural view) (2) has a shorter and less sigmoid (usually straight) lower palatal tooth (3) generally lacks an infraparietal tooth (4) has a smaller upper palatal tooth (occasionally slightly convergent with lower palatal) (5) has a more acutely angled, slanted columellar tooth, rarely drooping at the anterior end.

Remarks

There is considerable variation in the shell size and barrier length of specimens identified as Gastrocopta hedleyi during this study. Many specimens grouped as Gastrocopta hedleyi from the eastern Hamersley Range (eg. Wonmunna, Kalgan Pool) have reduced barriers and often a lower parietoangular tooth (nearing 45o angle in apertural view) but a large series shows a progression to shells that typically possess a large, strongly convergent upper palatal tooth and a strongly twisted parietoangular tooth.
Solem (1989)[7] mentioned that Gastrocopta hedleyi was somewhat similar to Gastrocopta pilbarana, although in that case he was actually referring to the ovate form of Gastrocopta mussoni (see section on Gastrocopta mussoni).
The abundance and seemingly allopatric nature of Gastrocopta hedleyi on the Burrup Peninsula is intriguing. The large numbers are presumably related to its’ habitat requirement of either Fig tree, Cypress or Brigalow Stands among rocky substrates, and its’ preference for high calcium soils (Pokryszko 1996[3]). Away from the Burrup Peninsula, the distribution of Gastrocopta hedleyi is somewhat patchy and is probably related to the isolated occurrence of its’ preferred vegetative structures among rocks as well as less alkaline soils.
