[Morphological observation on hypopus of Caloglyphus berlesei by optical microscope].

Objective: To understand the structure characteristics of hypopus of Caloglyphus berlesei.

Methods: The hypopus of C. berlesei was collected from the feed of Chinese Polyphaga, and was made into the conventional glass specimens. The structure characteristics of hypopus of C. berlesei were observed by an optical microscope.

Results: The hypopus of C. berlesei had 4 pairs of legs, and the foot claws and tarsus were well-developed. The structural features were shown, such as the setae of tibia and setae of genu. Genital plates were obviously ossified.

Conclusion: The research on hypopus of Caloglyphus berlesei provides the reference for its further scientific classification and research on the life cycle.
