Description
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description (Bingham, 1903) page 284 as Holcomyrmex glaber.

Worker

Major

Varying from brownish red to brownish black ; the mandibles, flagellum of the antennae and legs, sometimes the metanotum also, yellowish red to chestnut-red ; head, pro- and mesonotum very smooth, polished and shining ; the head anteriorly and the mandibles more or less finely longitudinally striate : the metanotum above finely transversely striate, the sides minutely but densely rugulose, opaque ; pedicel finely rugulose and opaque also ; pilosity more or less abundant (on the other two species almost entirely and in some specimens quite wanting) ; pubescence very sparse, except on the antennae and tarsi. Head, thorax, pedicel and abdomen typical of the genus.

Minor

Smaller, with the head somewhat smaller in proportion, generally lighter in colour, the flagellum of the antennae and the legs being a clear reddish yellow. Sculpture and pilosity as in the major.

Length: 3.5 - 7.5 mm

Karyotype

 * Monomorium sp.6:
