Identification
Myrmoteras yamanei is morphologically most similar to Myrmoteras danieli, Myrmoteras maudeae and Myrmoteras susanneae among the species known from the Sundaland. However, it is distinguishable from the latter three by a combination of the following characteristics of the worker:
- body generally dark brown, with antennae, mandible and legs (except tibiae and fore-coxa) yellowish brown (vs. reddish brown in M. susanneae; femora reddish brown in M. danieli and M. maudeae)
- body with sparse long erect hairs (vs. sparse short pubescence in M. maudeae)
- frons with irregularly rugose (vs. faint longitudinal rugae in the latter three)
- head in full-face view with frontal sulcus which is shallow and has posterior half wider than anterior half (vs. deep and has anterior half as wide as posterior half in the latter three)
- palp formula 5,3 (vs. 6,4 in M. maudeae and M. susanneae)
- mesopleuron smooth and shiny, but its posterior third with longitudinal rugae (vs. smooth and shiny in M. maudeae and M. susanneae; generally sculptured with anterior third smooth and shiny in M. danieli)
- metapleuron and lateral face of propodeum with longitudinal rugae and shiny (vs. smooth and shiny in M. maudeae and M. susanneae)
- dorsal face and posterior slope of propodeum in lateral view forming an angulate corner (vs. forming a round corner in the latter three)
