The unique modification of the ventral surface of the male pygophore differentiates this taxon from all remaining Schizopterinae and Schizopteridae.
Schizopteridae, the largest and best documented family of Dipsocoromorpha, are small (1-2 mm), sturdy, show variation and complexity of male genitalia that is unparalleled among Heteroptera, and are often strikingly sexually dimorphic with coleopteroid females sometimes featuring true elytra.
Emsley (1969), in his monograph on Schizopteridae, proposed three informal genus-groups within the subfamily Schizopterinae: the Corixidea group, Vilhenannus group, and a group comprising Humpatanannus Wygodzinsky, Bironannus Wygodzinsky, Ceratocomboides McAtee and Malloch, and Biturinannus Wygodzinsky, leaving Schizoptera Fieber, Nannocoris Reuter, and several other genera of uncertain affinity unplaced.
The mating behaviour and mating position of Schizopteridae is undocumented, but the diversity of pregenital and genital modifications in the group hint to fascinating male-female interactions.
Hypotheses on the homology of fore and hind wing venation of Schizopteridae were proposed by Emsley (1969) and Redei (2008).
Ceratocombomorpha, composed of the families Ceratocombidae, Hypsipterigidae, and Schizopteridae, is an additional infraorder to the 7 infraorders recognized at present in Heteroptera.
Furthermore, from the finding of a pair of m chromosomes in three species of Dipsocoridae and two species of Schizopteridae (Disp socoro morph a), Grozeva & Nokkala (1996) suggested that this pair of chromosomes might be included in the ancestral karyotype of the Heteroptera.
