TYPE: AUSTRALIA: Northern Territory: Male holotype from N of Walhallow, Tablelands Highway , 17 ° 37 9 30 0 S, 135 ° 41 9 19 0 E, 240 m (8 July–22 Sep. 2006, R. Raven, B. Baehr, A. Amey) (PBI_OON 00006198), deposited in QM (S81165) .

ETYMOLOGY: The specific name is a patronym in honor of Max Moormann, a young man who enjoys being on his hands and knees in the dirt discovering the secret life of the outback.

DIAGNOSIS: Males of C. maxmoormanni resemble those of C. michaelbellomoi as both have a very small sternal concavity (fig. 20). However, males of C. maxmoormanni have a strongly protruding epigastric scutum, relatively short posteromedially directed fangs just reaching the labium (fig. 20), and a flat, medially bent embolus with a slightly incised base (figs 136–138).

MALE: Total length 1.00. Carapace 0.48 long, 0.36 wide; abdomen 0.52 long, 0.30 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow. Sternum as long as wide with very small median concavity (fig. 20). Cheliceral fangs relatively short, not reaching labium, posteromedially directed forming V shape, tips not widened. Abdomen ovoid, epigastric scutum strongly protruding. Cymbium-bulb complex square with flattened embolus only slightly incised at base (figs. 136–138).

FEMALE: Unknown.

DISTRIBUTION: This species has been found only at the type locality in northeastern Northern Territory (map 5) .
