Abstract
The protonymph, deutonymph and male of Euvarroa sinhai (Acari: Varroidae) are described and compared with those of Varroa jacobsoni. Developmental changes occurring at the protonymph-deutonymph-adult moults are discussed. These include changes in the cheliceral structures; in the number of setae on the cuticle of the intercoxal region, palpal trochanter, femur and genu; in the structure of the peritremes, and in the size of setae on posterior margin of the female body. The adult male resembles a deutonymph and retains the undeveloped nymphal structure of the peritremes. Modification of the male chelicera for sperm transfer is accompanied by the enlargement of legs III-IV.
