Immature Stages of Pteromalidae (Cleonyminae)

Immature stages of Cleonyminae were discussed in detail by Clausen (1940), as follows:

The eggs of Cleonymidae had been described for only the three species by 1940 (Clausen 1940). Those of S. paillotti and S. sieboldi are elongate-oval or somewhat cylindrical in outline, and that of C. colon (Fig. 80A) is narrowed at both ends, with the anterior and drawn out into stalk-like form and at times folded back upon the main body after deposition. In S. paillotti and C. colon, the chorion is clothed with minute spicules though sparsely so in the last‑named species, whereas S. sieboldi bears instead a fine reticulation on one side.

The first‑instar larvae of the family are hymenopteriform, with small sensory setae and the integumentary setae may be uniformly distributed or in bands at the segmental margins. The respiratory system is equipped with spiracles on the mesothorax and first three abdominal segments.

The second‑ to fifth‑instar larvae present no distinctive characters. The sensory setae and integumentary spines are minute. Nine pairs of spiracles appear on the fifth instar, these being situated on the second and third thoracic and the first seven abdominal segments.
