Biology.

Associated with teak ( Tectona grandis ) ( Verbenaceae), presumably as habitat for the parasitoids’ host (unverified record taken from Noyes (2017)).

China (Oriental part), Malaysia, Myanmar, Philippines, Vietnam.

Taxonomic remarks.

Oodera ornata was synonymised with O. longicollis by Bouček et al. (1978); this was confirmed by us after examining the images of O. ornata available online (for exact reference see examined material).

Gahan (1925) compared O. ornata and O. gracilis and declared them similar, except for the different ovipositor lengths and some colour differences ( O. ornata "can be distinguished from that species [ Oodera gracilis ] at once by the much shorter ovipositor and the differently coloured legs"). After examining material of both species we found many more distinguishing characters (see diagnoses and key).

The species description of O. ornata by Gahan (1925: 97) points out that O. ornata (= O. longicollis ) is a species of "rather variable size". He characterised a specimen from Borneo as the smallest (body length: 7 mm) and a specimen from Mindanao (Phillipines) as the largest specimen (body length: 12 mm). We confirm the large size differences after examining the available material from various countries (smallest: 5.38 mm, largest: 12.6 mm). We see these large intraspecific size differences in both Oodera species for which we were able to examine a considerable number of specimens not originating from the same series and with both sexes available (i.e., O. formosa and O. longicollis ). Comparable differences might also be found for other species of Oodera if more specimens are examined. Because of this we use body length in the diagnoses and key but avoid using it as an exclusive character. This still holds a certain risk that users of the key will have difficulties to identify specimens of extreme body length. However, we think that body length is such an obvious character that it should be mentioned in identification keys. If the key might fail in rare cases, all specimens should be assignable to a certain species with the diagnoses provided.

Note that we located one additional specimen in the Australian National Insect Collection in Canberra (ANIC). It originated from the same series as specimens already included here (from Philippines, Davao/Mindanao). O. longicollis is a well-defined species and we did not borrow and include this additional specimen.
