13. C. sp. nr. antipodensisChironomus antipodensis was described by Sublette and Wirth(1980) from the Antipodes Islands. There has been no record of it from New Zealand itself, but a single, incomplete, adult male was collected near Dunedin, which is much darker than other known New Zealand Chironomus specimens, and has a mtCO1 DNA sequence that differs from other available coxI sequences. While it lacks a number of key identification characters, it seems to have relationship to C. antipodensis. Adult: A dark species, with dark setae that make those on the abdomen and the femurs much more obvious, i.e. it looks a quite 'hairy' species. AR, LR unknown. Wing length 5.12 mm, width 1.09 mm; VR - 1.04. About 4 setae on stem vein, about 23 on anal fringe. Head: Antennae missing, Frontal tubercles about 25 µm long and 13 µm wide, i.e. about twice as long as wide. Palpal proportions (µm) 73 : 65 : 276 : 311 ; (missing). 27 clypeal setae. Thoracic setae: Acrostichal - 11; Dorsolateral - 20-22 in up to 3 rows; prealar - 6; supraalar - 1; scutellar in three rows - 7, 7, and 12.
abt 15 sensilla chaetica on mid Ta1 Pupa: Not known. Larval Morphology: Larvae collected at the same time as this adult were one of the forms of C. forsythi, so larva of this species is not known. |
