Cyrtodactylus derongo new species
closing irregular rows of large, white tubercles
Description. A moderately large Cyrtodactylus; four adult females measure 105-112 mm snout-vent length, one specimen 81 mm in snout-vent length is immature; head about one and one-half times its breadth; eye, large, its diameter about one- third of the length of the head and about equal to its distance from, the nostril; diameter of ear opening less than half its dis- tance from the eye; head covered with granules, very small posteriorly and somewhat larger anteriorly; scattered, moderate- sized, pointed tubercles as far anterior as the interorbital region rostral large, rectangular, its breadth about 60 percent of its length, nostril bordered by the rostral, supranasal, first labial and 3 small shields; upper labials 11 or 12; lower labials 11 to
13; supranasals large, separated by 1 or 2 scales; one large pair of postmentals in contact posteriorly for about half their length; distinct lateral fold lacking, but its normal position marked by a row of flattish tubercles separated from one another by several smaller scales; in the mid-body region, 20 irregular lines of dorsal tubercles between the aforementioned rows of flattish scales; 15 to 1 8 rows in the axillary region ; some of the tubercles are white and tend to form widely separated irregular transverse lines, 8 to 10 between the nape and the hind limbs; undersurface of head with small granules; venter with about 46 to 48 rows of scales at the mid-body between the ventrolateral rows of tuber- cles, small and granular laterally, but merging gradually with the large cycloid scales of the mid-venter; the large preanal-pore scales in a \'ery shallow "/\" continuous with a row of femoral- pore scales that are gradually reduced in size along the femur; those anterior to the pore row somewhat enlarged, flattish scales on both the thighs and the preanal region, the latter merging with
those of the \enter; posteriorly the pore series is met abruptly by small granular scales in both the preanal and femoral regions; 24 to 26 rows of lamellae and scales beneath the fourth toe; tail only slightly depressed, with square or rectangular plates toe; tail only slightly depressed, with square or rectangular plates on the ventral surface and with everv fourth or fifth scale dis- tinctly enlarged.
Comparisons. Differs from other Indo-Australian species of Cyrtodactylus in the rather uniformly dark ground color of dor- sum marked by large white tubercles. The color pattern is remi- niscent of that of Underwoodisaurus milU, but in the latter the white patches in\'olve small surrounding scales, and the patches may be fused into partial or complete transverse bands. Com- pared to other New Guinean species, C. derongo is somewhat
