Other included species Twenty-two, including five species described as new here, see VandenSpiegel & Pierrard (2009) and Frederiksen & Enghoff (2012) . Diagnosis Differs from all other odontopygid genera, with the possible exception of Lissopyge , (see above) by the strongly developed gonopod sternum. Differs from Lissopyge by having solenomere and telomere of approximately same length, vs solenomere much longer than telomere in Lissopyge . Remarks In spite of two recent reviews ( VandenSpiegel & Pierrard 2009 ; Frederiksen & Enghoff 2012 ) new species of Xystopyge constinue to be discovered. In addition to those described here, several others have already been collected but remain unnamed so far. The known distrbituion of the genus covers eastern Kenya and Tanzania . See above concerning the differences between Xystopyge and Lissopyge , the only genera in subfamily Lissopyginae .
