Abstract

Eighty-one genus-group names are available in the arachnid Order Schizomida Petrunkevitch, 1945 by the end of 2025. All except one genus, i.e., 72 extant genera and eight extinct genera, are currently accepted. Seventy-four (91%) of the currently accepted genera were described since 1950. Schizomida includes 395 currently accepted species-group names (381 extant species and 14 extinct species) and a nomen dubium. Despite this descriptive activity, the suprageneric classification of Schizomida is poorly structured as phylogenetic relationships remain largely uninvestigated. Many recent genera are monotypic and narrowly delimited whereas several older genera appear to be paraphyletic. The systematics of African and Asian schizomids lags far behind that of Australian and New World schizomids.
