Type specimens
HOLOTYPE. Adult male. CHINA. Label 1: “Yunnan: Tengchong / 25 km NNW / N25.189°, E98.333° / 1900 m. / 01.VI.2009 leg. / Blank, Liston, Taeger / China 010”; label 2: “ Voucher code M. Reemer / 301 / DNA voucher labcode MZH:Y1095”. Coll. CSCS.
Diagnosis
This species keys to Microdon japonicus Yano, 1915 in the keys of Huo et al. (2007)[1] and Shiraki (1930[2], 1968[3]). From that species it is distinguished by the entirely yellow pilose mesoscutum (with patches of black pile in Microdon japonicus). In the key of Hironaga and Maruyama (2004)[4] it keys to Microdon kidai Hironaga & Maruyama, 2004, from which it differs by its partly yellow legs (entirely black in M. kidai). In the key of Violovitsh (1983)[5] this species keys to Microdon eggeri Mik, 1897 (= Microdon analis (Macquart, 1842)), from which it differs by its pale brown scutellum (black in Microdon analis) and the shape of tergite 2, which is at its widest clearly before the posterior margin (widest at posterior margin in Microdon analis).
Description (based on holotype)
Adult male. Body size: 11 mm.

Thorax. Entire thorax blackish with bronze hues, except scutellum brownish; all pilosity yellow. Scutellum trapezoid with slightly concave posterior margin; with slender calcars as long as 1/5 of length of scutellum, their mutual distance about equal to 1/3 of width of scutellum. Anepisternum with shallow sulcus separating anterior from posterior part; pilose anteriorly and posteriorly, with widely bare part in between. Anepimeron entirely pilose. Katepisternum pilose dorsally and ventrally. Katatergum long microtrichose, anatergum short microtrichose. Calypter and halter yellowish white.
Wing: Hyaline, subtly darkened around apical crossveins; microtrichose, except bare on basal 1/2 of cell br.
Legs: Black, except basal 3/5 of tibiae and ventral side of tarsi yellow; yellow pilose. Coxae and trochanters black; yellow pilose.
Abdomen. Tergites black. Tergites 1 and 2 yellow pilose. Tergite 3 black pilose, except narrowly whitish pilose along lateral and posterior margins.
