Subfamily Lissopyginae Attems, 1909

This subfamily contains only two genera, Lissopyge Attems, 1909 , and Xystopyge Attems, 1909 . The distinction between them is unclear. Thus, as mentioned in the introduction, the status of the gonopod sternum in Lissopyge remains uncertain, whereas in Xystopyge the gonopod sternum is large and conspicuous, in contrast to all other odontopygid genera. According to Kraus (1966: 85) the two genera further differ in the length and structure of the solenomere (“Rinnenast”): much longer than the telomere (“Tarsus”) and with teeth, lobes or spines in Lissopyge , vs same length as telomere and without peculiarities in Xystopyge . However, subsequently described species of Xystopyge ( VandenSpiegel & Pierrard 2004, Frederiksen & Enghoff 2012) do have various processes on the solenomere. The difference between the two genera in the relative length of solenomere and telomere, on the other hand, seems to hold.
