ICHNEUMONIDAE: : Casinaria Holmgren 1859
Diagnosis:
Characteristics of Casinaria include: 1. Body size <10mm; 2. Position of spiracle on T1 clearly behind the centre; 3. Shape of aerolet in forewing triangulate, petiolate; 4. Colour of face only black; 5. Metasoma compressed laterally; 6. Size of ocelli small; 7. Length of antennae as long, or longer than body; 8. Length of ovipositor barely visible; 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) not extending past spiracle; 14. Shape of T1 (viewed laterally) evenly curved; 15. Number of teeth in mandibles 2; 16. Patterns on metasoma same colour throughout, but sometimes bicoloured; 17. Length of 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 Taxa
Casinaria is most likely to be confused with other genera of Campopleginae.Compare

Species in NZ
Approximately three undescribed species.Biology & hosts
Casinaria is a large cosmopolitan genus that is well represented in the Australasian region. Nothing is known about the species in New Zealand, but in Australia they are parasitoids of Lepidoptera in the families Hesperiidae, Geometridae, Pyralidae and Notodontidae (Gauld 1984).Sources of information
