Microdon hauseri

Diagnosis
Subgenus: Microdon

Description
In the keys of Shiraki (1968), Huo et al. (2007) and – depending on how characters are interpreted – Hironaga and Maruyama (2004), this species keys to Microdon auricomus Coquillet, 1898, from which it differs by the largely orange legs and the long, orange-golden pilosity on the anterodorsal part of the hind femur. These characters also apply for distinguishing Microdon hauseri sp. n. from Microdon murayamai Hironaga & Maruyama, 2004, to which specimens of the species will key in the key of Hironaga and Maruyama (2004). The same characters apply for separating it from Microdon lateus Violovitsh, 1975, to which it keys using Violovitsh (1983). In the key of Shiraki (1930) this species keys to Microdon formosanus Shiraki, 1930, from which it differs by the black pilosity medially on the mesoscutum (entirely pale in Microdon formosanus).
