ICHNEUMONIDAE: : Campoplex Gravenhorst 1829
Diagnosis:Characteristics of Campoplex include: 1. Body size <10mm; 2. Position of spiracle on T1 clearly behind the centre; 3. Shape of aerolet in forewing is open or petiolate; 4. Colour of face only black; 5. Metasoma usually compressed laterally; 6. Size of ocelli small; 7. Length of antennae varies; 8. Length of ovipositor distinct not longer than body (rarely longer than the body); 9. Wings present; 10. Colour of wings hyaline (clear); 11. Sternaulus absent; 12. Shape of face in lateral view flat or only weakly bulging; 13. Sternite on T1 (viewed laterally) varibale (not extending past spiracle, or extending past spiracle sometimes forming a long cylinder with tergite); 14. Shape of T1 (viewed laterally) evenly curved; 15. Number of teeth in mandibles 2; 16. Metasoma same colour throughout; 17. Length of T1 vs T2 subequal in length, or T1 longer than T2; 18. Sculpture on mesoscutum finely pitted, many hairs; 19. Width of T1 (viewed dorsally) anterior part slender often parallel, strongly widening behind spiracle; 20. Glymma on T1 absent; 21. Sculpture on metasoma smooth with a semi-glossy or satin appearance at least on T2; 22. Propodeum reaching past coxal insertion, but not reaching halfway along metacoxae.
Similarity to Other TaxaCampoplex is most likely to be confused with other genera of Campopleginae.
No Glymma, the ovipositor is very short, barely visible, but females of Campoplex have a longer ovipositor, projecting beyond apex of metasoma by at least 0.5 times its length.
No Glymma, >10mm in size.
No Glymma, >10mm in size.

Biology & hostsCampoplex is an extremely large genus found around the world, and which can have a considerable range of morphological variation (Gauld 1984).
Campoplex is found throughout New Zealand including on some subantarctic islands. They are commonly collected. Little is known about their hosts, although they are parasitoids of Lepidoptera. Campoplex hudsoni has been reported from Izatha attactella (Oecophoridae).
