Diagnosis | Diagnosis: This species of Aspidura is characterized by a preocular scale that forms part of the anterior border of the orbit; a prefrontal scale that forms the remaining portion of the anterior border of the orbit and contacts supralabials two and three; having the lower postocular longer than the upper; both postoculars in contact with the parietal scale; and the anterior pair of the two pairs of chin shields two to three times the length of the posterior pair. Fifteen dorsal scale rows are present along the body, except in the region of the head, where two additional rows occur near the dorsal midline. These never persist beyond ventral number 16. The ventral counts range from 128 to 151 (mean = 137.66 +/- .84, N = 140) and subcaudals from 11 to 26 (mean = 18.70 +/- .74, N = 139). The subcaudals are undivided. Snout-vent lengths range from 85 mm to 383 mm. 8 tail lengths from 8 mm to 40 mm, midbody diameters from 2.5 mm to 13.9 mm (Table 2). Females tend to have more ventrals, and shorter tails than males, but males and females do not differ in total length. Fig. 2 compares the major counts, Fig. 3 the body proportions, and Figs. 7, 9, and 12 illustrate specimens. (Gans & Fetcho 1982) |
