Definition. Tentatively delimited supragroup of genera of Salticidae, having usually naked embolus, arising directly from bulbus and with spermophor following margin of bulbus, like in HYLLOIDA, but with additional, "S" resembling loop of spermophor in the center of bulbus. Bulbus itself is round or oval, epigyne with thin walled. often membranous ducts, usually bent loop-like, spermathecae oval, sclerotized. Many genera have multicusp, comb like cheliceral tooth on either retrolateral or prolateral edge of chelicerae, rarely on both.
Current progress. We owe interpretation of this supragroup to Maddison and it seems generally convincing, especially in placing SITTICINES inside it. Maddison (2015) divided AMYCOIDA into 9 tribes, leaving two more genera unclassified, since Maddison does not provide morphological definition of these poorly known groups I cannot report details of that proposal. I recommend readers to watch for further publications by Maddison and to draw own conclusions on merits of that divisions. (Written in 2016)

COMMENT: I am transfering hereby genus Synemosyna (type species: Synemosyna formica) to the chapter MYRMARACHNINES as a working hypothesis based on similarity of internal structure of epigyne - prticularly because of similarity of spermathecae consisting of ascending part of narrow, paralll "pipes" like part structures, running anteriorwards along the whole "vertical" diameter an passin near distal end into sort of receptacle of sperm (spherical, oval, loop or double spiral - usaallt armored inside with some spines) compare similar structures in almost all genera of Myrmarachnines. Internal structure of epigyne is a conservative, particuliary reliable absolute diagnostic characters. Differene in other characters are less reliable, often being adaptative.
