Expeditie (Third Archbold Expedition to
New Guinea), 5 km SW of Bernhard Camp,
Idenburg River, 850 m, 5 in Apr. 1939 (approximately
13914E, 326S; note that the
Idenburg River has been renamed Taritatu
River); QM J67250, MZB 3563, collected by
S. Richards and D. Iskandar on Apr. 9 and
13, 1998, respectively, at Wapoga Alpha

TYPE LOCALITY: Derongo is a village located
approximately 29 km N, 4 km W of
Ningerum and 12 km from the border with
Irian Jaya.
ETYMOLOGY: The name of the village that
was the provenance of many specimens is
used as a noun in apposition.
DIAGNOSIS: A moderate-size species of
Austrochaperina with maximum SVL of females
and males being 42 and 37 mm, respectively,
but some populations are evidently
smaller—females to 36 and males to
33 mm. The dorsal ground color is brown in
preservative, olive to reddish brown in life,
sometimes with dark speckles. Diagnostic
proportions include finger discs relatively
small, mean FD/SVL 0.031, EY/SVL
0.101, and IN/SVL 0.104.
DESCRIPTION OF HOLOTYPE: Adult female
with the following measurements and proportions:
SVL 35.6, HW 12.8, TL 15.2, EY
3.2, EN 2.7, IN 3.5, HD 7.9, FT 15.4, disc
of third finger 0.9 (penultimate phalanx 0.6),
disc of fourth toe 1.25 (0.55); HW/SVL
0.360, TL/SVL 0.427, EY/SVL 0.090, EN/
5 Earlier (Zweifel, 1956: 13), I gave this locality as 4
km, overlooking a footnote in Archbold et al. (1942:
239) that corrected several Expedition localities referred
to Bernhard Camp.
