Eidoreus Sharp, 1885: 146 .
Type species: Eidoreus minutus Sharp, 1885 .
Eupsilobius Casey, 1895: 454 . Pseudalexia Kolbe, 1910: 34 .
This genus has a peculiar distribution: it is known mainly from widely scattered islands around the globe: Antilles, Hawaii, Galapagos, Seychelles, Samoa, Sri Lanka, Japan, etc. (Pakaluk & Ślipiński 1995). Sen Gupta & Crowson (1973) studied specimens from México and Belize and established the synonymy of Eupsilobius and Eidoreus . Members of this genus are rarely collected; their most frequent habitat seems to be forest debris. Although Eidoreus specimens have been found in association with ants, the nature of this relationship is unclear (Pakaluk & Ślipiński 1995). One species in México.
