Introduction 
The southern temperate silphid genus Glypholoma Jeannel was 
transferred to the staphylinid subfamily Omaliinae by Newton 
(1975), and Lathrimaeodes Scheerpeltz (originally placed in the 
Omaliinae) was then synonymized with it. Newton (op. cit.) also 
presented additional descriptive information, a new locality record, 
and some discussion of the affinities of Glypholoma within the 
Omaliinae. Since that time, four new species of the genus have come 
to our attention, including one from Australia which greatly 
enlarges the known range of Glypholoma (previously only parts of 
Chile and Argentina). The discovery of these new species and the 
availability of a wealth of material of the type species , pustuliferum 
Jeannel, for detailed study led to our decision to revise the genus. 
Methods 
Measurements, made with an ocular micrometer in a Leitz 
binocular dissecting microscope, are defined as follows: 
Length: measured in lateral view from front of (closed) mandibles 
to apex of abdomen (excluding genitalia if exserted, and attempting 
to estimate “normal” degree of contraction of abdomen). 
Width: maximum body width, across closed elytra at widest point 
(usually near middle). 
Head width: in dorsal view, maximum width including eyes. 
Head length: measured along midline from anterior margin of 
labrum to level of centers of ocelli, viewed perpendicular to line of 
measurement.
