type image: A. elegansOriginal description: Shell three-sided pyramidal, with three annular strictures. Length of the four joints = 1: 2: 9: 3. Cephalis small, hemispherical, with two large, prismatic, divergent horns of three times the length. The three prominent edges of the second and third joints are finely latticed and dentated, and at the basal end of the third joint are prolonged into three stout, free, pointed, pyramidal, divergent wings, about as long as the horns. The fourth joint is only as long as the second, three-sided prismatic, its wide triangular mouth is armed with six parallel, vertical, slender teeth (two between every three wings). Network very delicate and regular, in the first and second joints with circular, in the third and fourth joints with small hexagonal meshes.
Remarks on original description: Haeckel listed Artopilium elegans under the subgeneric name Trictenartus, but did not include the subgeneric name in the species name.[comment from RadWorld database]
