Diagnosis and Specialized Morphology
Species of Hammacerinae are characterized by:
1) head is strongly produced anteriorly and is not constricted or elongated behind the compound eyes
2) stout, inflexible, and curving labium
3) antennal pedicel annulated into 4-36 pseudosegments
4) forewing membrane with 2 closed cells
5) fossula spongiosa present on fore and middle legs
This group was originally proposed as a subfamily by Stal (1859), and is sometimes referred to as Microtominae. This subfamily consists of two Neotropical genera (19 species): Homalocoris Perty and Microtomus Illiger. Microtomus was revised by Stichel (1926).
Hammacerinae appear to live under bark (Readio, 1927).
