TYPE: AUSTRALIA: Queensland: Male holotype from 23 km ESE of Cloncurry near Bishop Creek , 20 ° 47 9 05 0 S, 140 ° 42 9 49 0 E, 210 m (29 June–9 Sep. 2006, R. Raven, B. Baehr, A. Amey) (PBI_OON 00006073), deposited in QM ( S75110 View Materials ) GoogleMaps .

ETYMOLOGY: The specific name is a patronym in honor of Heidemarie Barth and her family.

DIAGNOSIS: Males of C. barthorum resemble those of C. foxae , with the sternal concavity occupying the whole sternal length (fig. 11) and the epigastric scutum not protruding. However, males of C. barthorum can be easily separated by the rounded anterior margin of the clavate field (fig. 11) and the ovoid cymbium-bulb complex, with a smoothly, medially bent, corkscrew-shaped embolus (figs. 87–89).

MALE: Total length 1.08. Carapace 0.49 long, 0.37 wide; abdomen 0.59 long, 0.25 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow. Sternum longer than wide, with oval field of clavate setae reaching anterior margin, covering about 4 = 5 of sternum length and about K of sternum width, anterior margin with rounded edges, with bare median band (fig. 11). Cheliceral fang elongated, fangs extremely long, thin, bent, and crossed (fig. 11). Abdomen ovoid, epigastric scutum not protruding. Cymbiumbulb complex ovoid with a broadly based and corkscrew-shaped embolus (figs. 87–89).

FEMALE: Unknown.

DISTRIBUTION: This species is found only at the type locality, in western Queensland (map 2) .
