“…The larvae of Apocrita are characterized by a lack of sclerotization (Short, 1952(Short, , 1978, and the lack of sclerotization is considered to be the plesiomorphic condition in the Chalcidoidea. In some chalcidoid larvae there is an increase in the overall degree of sclerotization (Group 111 larvae; Parker, 1924;Parker & Thompson, 1925), but distinct tergites have been described only in the planidial larvae and in Chrysolanipus thenae (present study). We regard the formation of twelve distinctly sclerotized and pigmented tergites as a synapomorphy of Eucharitidae, Perilampus, and Chrysolampus thcnae.…”

Abstract. The eggs and first‐instar planidial larvae of Stilbula montana, Kapala sp., Pseudometagea schwarzii, Orasema sp. (Eucharitidae), Perilampus chrysopae, Perilampus fulvicornis, Perilampus hyalinus (Perilampidae), and Chrysolampus thenae (Pteromalidae: Chrysolampinae) are described. The morphological data are coordinated with the information available in the literature to develop general descriptions for the planidial larvae of Perilampus and the Eucharitidae. Character states were polarized with reference to a ground plan chalcidoid larva and relationships were determined cladistically. Nine synapomorphies are suggested for the planidial larvae of Perilampidae and Eucharitidae, indicating a possible sister group relationship. A re‐examination of the larvae of Chrysolampus thenae indicates that the Chrysolampinae could be the sister group of Perilampidae + Eucharitidae.

“…Parker (1924) and Parker and Thompson (1925) are the oldest references for Ormyridae larvae. Parker (1924) contains a drawing of an ormyrid egg spiracle, whereas in Parker and Thompson (1925), ormyrids are included in a group with the Eulophidae, Elasmidae and two genera of the family Torymidae ( Megastigmus and Callimomus ). The group included ectoparasitic larvae with a well-defined head, thirteen body segments, an integument without pigmentation, and a barely sclerotized body with short setae or that is glabrous and four spiracles between segments II and VI.…”

A systematic study of the genus Ormyrus (Chalcidoidea, Ormyridae) was conducted based on the morphology and biology of the terminal-instar larvae of ten west European species that are parasitoids of gall wasps and gallflies of the families Cynipidae, Eurytomidae and Tephritidae. The first detailed descriptions are provided of the terminal-instar larvae of these ten species using SEM images to illustrate diagnostic characters with systematic values. A key is provided for the identification of ormyrid larvae associated with galls in Europe, which is based particularly on characters of the head, mouthparts and mandibles. Although only limited informative variation in body shape was found, the setation of the head provided several characters of potential taxonomic value. The larval biology of the ten ormyrid species inhabiting different galls is also summarised. Although Ormyrus larvae are usually solitary idiobiont ectoparasitoids of the host larva of various gall-inhabiting insects, evidence of secondary phytophagy was observed in some species.
