Diagnosis and Specialized Morphology
Species of Physoderinae are characterized by:
1) tuberculate body with spatulate setae
2) elongate head with small compound eyes that are far from the anterior margin of the pronotum
3) labial segment 3 very long and straight
4) forewing membrane with 2 cells
5) absence of fossula spongiosa
The subfamily status of Physoderinae was established by Miller (1954).
About 38 species (12 genera) have been described, most of which occur in the Indo-west Pacific area (Schuh & Slater 1995); the species Cryptophysoderes fairchildi Wygodzinsky & Maldonado has been described from Panama. Specimens of the subfamily have been found in caves, hollow trees, vegetable debris, and at the bases of banana and Pandanus leaves (Schuh & Slater 1995).
