|Types||Types: BMNH 19188.8.131.52-26 (and possibly additional specimens).|
|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 upper postocular longer than the lower or both subequal in length; only the upper postocular 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. Seventeen dorsal scale rows are present along the body. The ventral counts range from 103 to 122 (mean = 112.48 ÷ 2.53, N = 23) and those of subcaudals from 18 to 29 (mean = 22.35 ‡ 1.12, N = 23). The subcaudals are undivided. Snout-vent lengths range from 75 mm to 160 mm, tail lengths from 11 mm to 26 mm, midbody diameters from 2.8 mm to 5.0 mm, making this the smallest and most slender species of the genus (Table 2). Females have fewer caudals and a shorter tail a than males, but are larger overall. Fig. 2 compares the major counts, Fig. 3 the body proportions and Figs. 7, 9, and 12 illustrate specimens.
