Extract

Sex anomalies have been used in an attempt to homologize the male and female genitalia of insects. Studies of some sex anomalies (Michener, C. D., Ann. Ent. Soc. Am. 37: 336-351.1944) suggest that the second valvifers are homologous with the gonocoxites (phallobase); the second valvulae probably are homologous with the penis valves; and the third valvulae are homologous with the gonostyli (parameres). Homologues of the first valvifers and first valvulae of the female are absent in the males of Pterygota.
