    • n mentum In entomology, the median or central and usually principal part of the labium. The term has been applied to different parts of the labium, in different insects and also in the same insect, whence confusion has arisen, especially in the use of the terms mentum and submentum. The mentum is properly the part of the labium between the submentum and the ligula, and is often less conspicuous than either of these. See labium, and cut at mouth-parts.
