Monophyly and relationships: Following Simon (1901), Galiano (1968) recognized the relationship of Acragas , Amycus , Encolpius , Hypaeus , Mago and Noegus based on several characters, including a high carapace, pluridentate chelicerae, and the third leg longer than the fourth. The first two of these are seen in other amycoids, but the longer third leg is unique among amycoids and can be considered a synapomorphy. Although it can be reduced or lost in some species, amycines generally have large mastidia on the male chelicerae. Many amycines are translucent, with few scales on the legs. Another common characters is the high clypeus in males.

Monophyly of the amycines was strongly supported by the All Genes analysis ( Fig. 37 ) and separately by 28S, actin 5C, and 16SND1 genes ( Figs 39, 41, 43 ). The molecular phylogeny strongly supports a basal division of amycines into Encolpius and the remainder as sister groups. Noegus and Hypaeus are resolved as sister groups, as expected because of the developed male eyebrows and similar male palps. Acragas and Amycus are sister groups by both the molecular phylogeny and morphology, sharing an extremely high clypeus and elongate chelicerae with a modified promarginal tooth.

Numbers show likelihood bootstrap % for Amycoids only; in parenthesis are bootstrap percentages for analysis without Nilakantha and Gypogyna (shown for deep amycoid branches only). Rectangles at nodes indicate bootstrap support in parsimony analysis (filled rectangle at least 75 %; open 50 % to 74 %). Sites partitioned as per PartitionFinder analysis.
