Synonymy: Boulenger (1885) synonymized Aporarchus prunicolor to Amphisbaena darwini, based on the evidence that the holotype was a young specimen in which the pores are undistinguishable (or absent), observation also seen in young specimens of A. darwini by Boulenger (1885).
Original description from COPE (1885): The genus [Aporarchus] has been defined in the key under the head of the species Anops kingii. It is simply Amphisbaena without preanal pores.
The only specimen on which the species rests is of smaller size than those which represent the species enumerated in the above table, excepting the A. occidentalis, which is the smallest of the genus.
Rostral plate scarcely visible from above ; common suture of nasals short; nasofrontals each as long as broad; frontals each longer than broad; a pair of well distinguished square parietals. Labial, 3-3, the third reaching the ocular, so that there is no subocular. No superciliary or preorbital plate. Three plates in the row from canthus oris to frontal plate. Symphyseal broader than long, truncate posteriorly; postsymphyseal broad as long, subcircular, each half bounded by the postgeneial, and first and second labials to an extent represented by the order of mention. Last inferior labial twice as long as deep. Annuli 186 on the body and 23 on the tail. Preanal scales eight, the row preceded by a groove which is wider than the others. Tail obtuse, caudal annuli entirely smooth.
Total length, M. .214 ; of head to canthus oris, .006 ; of tail, .029.
Color, uniform plum-color above and below, excepting the lower jaw, chin and part of pectoral region and a postanal crescent, which are white. All the grooves of the inferior surface are white also, so that the animal has a latticed appearance below.
Type Species: This species is the type species of the genus Aporarchus which is distinguished from Amphisbaena only by the lack of precloacal pores.
