Genus 5. Ctenotilla Bischoff, 1920

Diagnosis. FEMALE. In the Oriental and Palaearctic regions, this is the only mutilline genus with a transverse row of teeth on the propodeum and with the disc of T2 lacking setal spots. This genus is separated from similar Afrotropical genera by having T1 as broad as the propodeum and having the gena not armed with a dentate carina. MALE. See Nonveiller (1979) and Lelej (2005).

Diversity and Distribution. Three species are recognized: C. caeca (Radoszkowski, 1879), which is widespread in the Palaearctic; C. porcella (Turner, 1911) from India and Sri Lanka; and C. guangdongensis Lelej, 1992, which is known from China and Thailand.

Remarks. The Chinese and Thai species, C. guangdongensis, is the only one presently known from females only.
