Microtendipes Kieffer, 1915

Qi, Xin, Lin, Xiaolong & Wang, Xinhua, 2012, A new species of the genus Microtendipes Kieffer, 1915 (Diptera, Chironomidae) from Oriental China, ZooKeys 212, pp. 80-89 : 82-84

Genus Microtendipes Kieffer, 1915

Microtendipes Kieffer, 1915: 70; Pinder 1978: 128; Qi and Wang 2006: 37.

Type species.

Tendipes abbreviatus Kieffer, 1913 [= Chironomus chloris (Meigen, 1818)]

Diagnosis.

Most males of Microtendipes can be distinguished from all other Chironomini by one or two rows of stout, proximally directed setae on the fore femur. Additionally, the hypopygium of some species generally has a tubercle or wart-shaped median volsella often bearing a tuft of long setae. Species without the above characters require association with immature stages for correct placement in the genus; moreover, Microtendipes can be divisible into two species-groups (pedellus group and rydalensis group) with recourse to immature stages. The characters of larva are as follows: the body is large, red to orange coloured, up to 15 mm long; the antenna has 6 segments; the lauterborn organs alternate on apices of segments 2 and 3; the mandible has 3 inner teeth; the median trifid is either pale or as dark as remaining teeth with very small median tooth (maybe absent); the lateral and ventral tubules are absent.

Distribution.

Palaearctic, Oriental, Nearctic, Neotropical and Australian regions.
