Biology

The single specimen of S. anderseni was caught in a pitfall trap, and nothing is known about its biology.[citation needed]

Systematics

Stereomyrmex is probably the sister taxon to Romblonella. Closely related genera are Leptothorax and Cardiocondyla.[3]

Description

Stereomyrmex dispar is 3.2 mm long and black, with yellowish brown mandibles, antennae, legs and terminal segments of gaster. S. anderseni is only 2 mm long, has a very different petiolar and postpetiolar structure and is paler in color.[3]

Distribution

Stereomyrmex dispar has been described from a single worker, taken in 1933 on Bellona Island, Solomon Islands; no other specimen has since been found, and it is unlikely that the species is truly endemic to Bellona. S. anderseni is known from a single worker as well.[3] S. horni was collected under rocks in Sri Lanka.[4]

Names

The genus was originally named in honor of Maurice Willows Jr., who collected the type specimen of S. dispar.[5] S. anderseni was collected by A.N. Andersen. S. horni was collected by W. Horn.[citation needed]
