Diagnosis and Specialized Morphology
Pseudocetherinae are sometimes referred to as lobe-headed bugs. Most members of this subfamily are characterized by:
1) short mandibular plates with apices well separated by clypeus
2) maxillary plates with large anterior projection
3) forewing membrane with a small triangular Cu-PCu cell
4) first visible labial segment long and slender, longer than the 2nd and 3rd segments combined
5) antennal scapus short and not or only slightly surpassing apex of head
6) prosternum projecting anteriorly, forming a nearly ventrally flattened surface
7) dorsal abdominal glands entirely absent in adults
In 1963, Villiers described the genus Pseudocethera and he erected a new subfamily, Pseudocetherinae, to accommodate it. The systematic position of the genus, which currently contains three species, was modified subsequently by different authors; some placed it in Cetherinae, others retained the subfamily Pseudocetherinae. Re-examination of Pseudocethera clarified that the genus differs rather sharply from both Cetherinae and “Reduviinae sensu stricto” (= the monophyletic line, which contains Reduvius, within the current, probably not monophyletic Reduviinae or “Reduviinae sensu lato”). Therefore, its inclusion in a separate subfamily seems justified.
Nothing is currently known of Pseudocetherinae life history.
