Introduction

Given the considerable uncertainties regarding the classification of Cyamioidea and Galeommatoidea, we maintain the traditional classification here until more comprehensive revisionary work involving sampling of additional key taxa is undertaken. Basteriotiidae is often treated as a separate family from Sportellidae in recent works, but no real justification has been offered; here the genus Basterotia is maintained in the Sportellidae. Also, molecular studies (Giribet & Distel 2003; Taylor et al. 2007; Goto et al. 2012) have Basterota included within Galeommatoidea. Gamardia was shown by Taylor et al. (2007) to be far removed from Galeommatoidea, but there are no DNA data for Cyamium or similar genera.
