TYPE: AUSTRALIA: Queensland: Male holotype from 19 km NW of Winton by road ,

22 ° 16 9 11 0 S, 142 ° 55 9 34 0 E, 212 m (29 June–7 Sep. 2006, R. Raven, B. Baehr, A. Amey) (PBI_OON 000060700), deposited in QM ( S75125 ) .

ETYMOLOGY: This specific name is a patronym in honor of the German-Australian travel agency, the Worldwide Travel Angels.

DIAGNOSIS: Males of C. gatangel resemble those of C. ewani , with the median sternal concavity occupying nearly the whole sternal length (fig. 16). However, males of C. gatangel can be easily separated by their shorter cheliceral fangs, their widely triangular field of clavate setae, and the cone-shaped cymbium-bulb complex with a thin, medially bent embolus which is incised at base (figs. 120– 122).

MALE: Total length 1.00. Carapace 0.47 long, 0.40 wide; abdomen 0.53 long, 0.35 wide. Carapace, sternum, mouthparts, and abdominal scutae pale orange, legs yellow. Sternum as long as wide with broad, triangular field of clavate setae, covering most of sternum, bare median band half as long as covered field and equal in width (fig. 16). Cheliceral fangs not reaching labium, crossed, tips distally widened. Abdomen ovoid, epigastric scutum not protruding. Cymbium-bulb complex cone shaped with a thin, medially bent embolus incised at base (figs. 120–122).

FEMALE: Unknown.

DISTRIBUTION: This species is known only from the type locality in midwestern Queensland (map 4) .
