Dorsum of head and body brown to dark brown to charcoal with few, faintly evident, scattered irregular brown to black spots. Flanks brown to black, with a cream oblique lateral stripe extending from the groin anteriorly to about level of mid-body. The black flank surfaces end in a distinct linear border with the white ventral surface, and the mustard-yellow pigment around the arm and leg insertions; aside from this sharply delineated border, no distinct separate pale ventrolateral stripe is evident in life or after preservation. The flanks are dark brown-gray anteriorly and light gray washed with cream posteriorly. Lateral surfaces of head (from below

to the ventral margin of the eye) dark brown to black; upper lip (from ventral margin of eye to mouth) cream, with a faint wash of pale gray pigment. Dorsal surfaces of legs light brown with diffuse dark brown markings consisting of 3 transverse dark brown bands on dorsal surfaces of thighs, with a thin longitudinal stripe of the same color running posteriorly the length of each thigh; shanks with 4 transverse bands of the same color combination as bands on thighs; ankles also with dark brown transverse bands over brown dorsally. Ventral, and proximal antero-ventral surfaces of thighs bright mustard-yellow (remaining antero-ventral surfaces of thighs light brown); this mustard-yellow pigment also extends across the groin, and posterior belly. Light mustard-yellow paracloacal marks present. Ventral and antero-ventral surfaces of shanks also are bright yellow, yellow extending onto the anterior surface of the ankle and fading along the proximo-dorsal surface of the foot. Dorsal and anterior surfaces of arms light brown with dark brown transverse bands and irregular marks; ventral surfaces of arms and hands gray. Proximal 1/2 of the posterior and postero-ventral surfaces of upper arms bright mustard-yellow (same color as on thighs), extending in an arc around the dorsal, posterior, and ventral circumference of each arm). This arc of mustard-yellow pigment is narrowest on that portion of the flanks of the body immediately dorsal to the arm insertion (where it ends at a sharply-defined border with the black lateral surfaces), and then broadens posteriorly (forming a crescent-shaped mustard-yellow mark also defining a crescent-shaped border with the black lateral surfaces), and ventrally (the ventral portion of this half-circle is the largest, with mustard-yellow pigment extending to a radius around the postero-ventral area of the arm insertion to a width of approximately 1/2 the length of upper arm).The iris was gold to copper/brown, with scattered small irregular black markings.

. Overall, the dark pigments on the dorsal and lateral surfaces of the body and limbs appear darker and less bright than in life, especially for pattern features that are narrow or small. All major features of pattern (pale or dark bands and stripes, ground color) remain nearly as distinct as in life despite this darkening. The white ventral ground color has faded to a dull cream, but darker pigments remain clearly visible aside from some fading, and all areas that were bright mustard-yellow in life have lost all trace of pigment, leaving only the underlying ground color (dull cream in ethanol).

In some individuals, the patches and spots of dorsum are more evident over the background brown color. The posterior flanks vary from cream to gray with the pattern from irregularly spotted to reticulated, gradually fading into the pale ventral pattern. In some specimens, the longitudinal stripe running the length of each thigh is bordered posteriorly by a lighter stripe. Bright mustard-yellow markings in the groin and upper arm areas were clearly visible in life in all specimens. The paracloacal mustard-yellow marks are also present varying from light (

In both sub-adult and adult females, the anterior ventral surfaces (chin and throat) are cream to white with a faint and diffuse pattern of pale brown to gray flecks (in life and after preservation); in some individuals, these flecks coalesce to form a reticulated pattern, but this is not pronounced and can be readily seen only under magnification, and the entire abdomen is unmarked cream to white

Despite the differences in dorsal, lateral, and oblique lateral stripe color as compared to sub-adults and adults, all three juveniles also exhibited obvious bright mustard-yellow flash marks in the axillary and groin regions. One noteworthy observation among these three juveniles pertains to their relative sizes in comparison to the respective lengths of their tail remnants; the two smallest juveniles (

The nasals are subcircular, bearing an acuminate posterolateral maxillary flange, but do not articulate with the pars facialis of the maxillary. The nasals are widely separated medially. The ossified sphenethmoid slightly underlies the posterior margins of nasals. The frontoparietals overlie the anteromedial prootic posterolaterally; the orbital edges of the frontoparietal are straight. The frontoparietals lack medial articulation. The crista parotica is well developed, long, and narrow; the occipital condyles are widely separated. The squamosal is moderately developed; the otic ramus articulates with the cartilaginous lateral margin of the crista parotica. The pterygoid is moderately developed, the medial ramus is not in contact with the ossified prootic; the anterior ramus extends to the anterior orbit and is in broad contact with the cartilaginous pterygoid process of the palatoquadrate adjacent to the pars dentalis of the maxilla.

The alary process of the premaxilla is narrow and curved posterolaterally; the pars palatina of the premaxilla is well-developed and broadly “U”-shaped in ventral aspect. The mentomeckelian bone is slightly constricted, about equal in width at medial and lateral ends. The angulosplenial extends posterior to the jaw articulation. The vomer is small, edentate, and bears a small pre- and a large postchoanal process bordering the anterior and lateral margins of the choana, respectively. The neopalatine is absent. The planum antorbitale is cartilaginous. The parasphenoid is “T”-shaped and lacks dermal modifications; the alae are acuminate, directed slightly posterolaterally; the cultriform process is about twice as wide as transverse length of alae; the anterior end of the cultriform processes bears large bifid projections and extends to the anterior region of the orbit. The pars media plectri of columella is slender. The tympanic annulus is sickle-shaped, with the open side upper. The tympanic region bears a cartilaginous round plate.

The pectoral girdle is firmisternal; an omosternum is present. The style of the omosternum is ossified. The distal end of the style bears a short, broad cartilage. The xiphisternum is rectangular and basally calcified. The clavicles are oriented horizontally, forming an L with the outer lateral extreme. The coracoids are moderately robust, oriented so that the sternal end lays posteromedial to the glenoid end. The medial margin of the pectoral fenestra is formed by the coracoid; the calcified epicoracoids are abutting one another, narrowly separated anteriorly. The procoracoid cartilage is present, of uniform depth throughout transverse width. The cleithrum is distally bifurcate. The suprascapula lacks calcification in the margins.

The deltoid crests on the humerus are prominent. The phalangeal formula of the hand is 2-2-3-3. The prepollex is composed of two elements, with the basal element calcified. The distal transverse processes of the terminal phalanges on the fingers and toes are twice the width of the terminal phalange at midlength. The astragalus and calcaneum are fused proximally and distally. The phalangeal formula of the foot is 2-2-3-4-3. The terminal phalanges are “T”shaped. The prehallux is composed of 2–3 cartilaginous elements; the basal element is calcified. There are three ossified tarsal bones and two tarsal sesamoid bones. There are one or two large sesamoid bones at the joints of phalanges of fingers, smaller and single ones on the toes.

in duration. Two inter-call periods are 25 and 68 s. Overall note repetition rate was 1.35 notes per second, or 81.2 notes per minute. The notes were produced at regularly spaced intervals, (inter-note interval being 431–471 ms, mean = 443, SD = 16); however, the inter-note interval was shorter between some note pairs resulting in a double peep being heard. Only 12 double peeps were present in the entire sample of 237 notes and were never emitted more than three times in succession. In double peeps the inter-note interval was shorter (336–416 ms, mean = 363 ms N = 3), and between the pairs of double notes was longer (660–666 ms, mean = 662 ms, N = 3). Each peep was a weakly pulsatile frequency modulated note (rising from lower to higher) with a duration of 127–182 ms (mean = 153, SD = 17). The dominant frequency arose from 3310–3398Hz (mean = 3340, SD = 28.9) to 3660–3722 Hz (mean = 3691, SD = 25.4). The fundamental frequency was about 1660 Hz rising to 1820 Hz. Four higher harmonics were present, their starting frequencies being about 4940, 6620, 8360, and 9890 Hz respectively.
