Type. BMNH

Distribution. E (Alameda, Contra Costa, Riverside, Sacramento, San Diego, Stanislaus, Yolo)

Remarks. This appears to be a tropical species that has become adventitiously established around the world. This species was imported into California using Hawaiian stock in a biocontrol programs against cockroaches in the late 1970 s and was reported established ( Slater et al. 1981). However, there is a single specimen from Contra Costa County ( EMEC) collected in 1957, indicating the species was probably already present in the state. Gomes (1942) reported Blattella germanica as a host, but Roth and Willis (1960) noted that this was not based on rearing records. Lawson (1954) reported that C. merceti was unable to attack Blatta orientalis and Periplaneta americana ootheca, but a single specimen ( UCRC) was reportedly reared from a Periplaneta sp.
