DESCRIPTIONS OF MATURE LARVAE OF 2 AMISEGINAE, WITH A DISCUSSION OF LARVAL CHARACTERS IN THE CHRYSIDIDAE (HYMENOPTERA)

The mature larvae of 2 species of Amiseginae - Adelphe anisomorphae Kr ombein and Myrmecomimesis bispinosus (Riek) - are described. These lar vae share with other Chrysididae and with Bethylidae a simple atrium a nd an opening toward the unarmed subatrium. As in the Bethylidae, they lack a coronal suture and parietal bands. Several characters are shar ed with Cleptinae and Chrysidinae (Chrysididae): a labrum with sensill a and a notched anterior margin, and a well-developed peritreme. The p resence of 2 antennal sensilla. and the absence of setae on labrum and maxillae are, among the Chrysididae exclusive to Amiseginae. The phyl ogenetic importance of these preimaginal structures is discussed.
