CRYPTOPHAGIDAE Author: John F. Lawrence, 2001. Classification Suborder Polyphaga, Series Cucujiformia, Superfamily Cucujoidea. Description Antenae with 11 segments and a 3 segments club. Antennal insertions exposed or concealed. Visible portion of procoxa transverse with the trochantin concealed. Procoxal cavity externally open and internally open to closed. Mesocoxae separated by 0.4 to more than 1 coxal width, with mesocoxal cavity laterally closed. Tarsal formula 5-5-5 or 5-5-4 in males of some species. Number of ventrites 5 without ventrites connate. Body length 1-2.8 mm. Broadly ovate to oblong and glabrous to setose. Not common in Central American collections: usually with serrate lateral pronotal margins or approximate antennal insertions. Elytral epipleura incomplete and first ventrite much longer than others. Quick identification Cryptophagidae are poorly represented in Mesoamerica. Those genera which do occur here either have lateral teeth or serrations on the prothorax (first and second figures) or have the antennal insertions close together (last two figures). They may be distinguished from the next family by having incomplete elytral epipleura and an enlarged first ventrite.
