Comment: According to SCHÜLKE & SMETANA (2015), this cosmopolitan species was previously unknown from Greece, Cyprus, Israel, Yemen, North India, and the Chinese provinces Shanghai, Hubei, Guangxi, Jiangsu, and Yunnan.

All the above specimens are females, suggesting that this species is parthenogenetic. COIFFAIT (1984) figures the aedeagus of a male from Cameroon, but this specimen may well belong to a different species.
