Archipsocus is a of bark lice (Psocodea: Archipsocidae) established by Hagen in 1882. The genus comprises approximately 25 described distributed primarily in tropical and subtropical regions worldwide. Species within this genus are distinguished by subtle morphological differences, particularly in antennal segment proportions and phallic frame structure. Archipsocus nomas was the first North American record, reported from New Orleans in 1934.
Identification
-level identification within Archipsocus requires examination of minute morphological details; no single diagnostic feature applies to all species. Useful characteristics include relative lengths of antennal segments and the shape of the phallic frame. Separation from the related Archipsocopsis (which includes parthenogenetic species producing live young) is based on reproductive mode and associated morphological traits.
