Holotype ♂: (1) „ China; Sichuan; Old Creek / field station; 17.viii.2016; / 32.484°N, 104.72°E; 1370 m; / Light trap; M. Hauser; / FFP16CH091 “; (2) „Holotypus / Hauserimyia martini / spec. nov. ♂ / det. Stuke 2018 “. Holotype is deposited in the collection of the California Academy of Sciences, USA, San Francisco, (CAS). The holotype was initially kept in alcohol and dried afterwards. It is complete and in a very good condition (Fig. 14).
9 ♂♂, 3 ♀♀ paratypes: 4 ♂♂ same data as holotype but collected with Malaise trap 17.−20.viii.2016, leg. M. Hauser, C. J. Borkent, T. Zhang, FFP16 CH 080; 1 ♂ same data as holotype but hand collected, FFP16 CH 088; 2 ♂♂ same data as holotype but hand collected at 18.viii.2016, FFP16 CH 094; 1 ♀ China, Sichuan, Old Creek field station along stream beside field station, 19.viii.2016, hand collected, leg. M. Hauser, FFP16 CH 100; 2 ♂♂ 2 ♀♀ China, Sichuan, Old Creek field station, 32.494°N 104.723°E, 1430 m, Malaise trap 17.−20.viii.2016, leg. M. Hauser, C. J. Borkent, T. Zhang, FFP16 CH 086. Paratypes are deposited in the collections of California Academy of Sciences (CAS) and the private collection of the author (Germany, Leer, PJHS).
Description of holotype (♂): Length 9.2 mm.Wing-length 6.7 mm. Head-height 2.3 mm. Antenna orange-brown with pedicel and first flagellomere dorsally and arista black (Fig. 15). Frons (Fig. 16) broader than long, slightly concave, not projecting above eyes, smooth and lacking setulae. Frons brown with a black central stripe and a narrow black stripe laterally at eye margin which reaches anteriorly to a small black frontofacial spot. Lunule black. Frons with golden dusting in posterior half and along eye margin (in anterior view). Distinct rugose light yellow area between frons and ptilinal suture. Face yellow. Facial keel ventrally light brown. Gena yellow. Parafacial and antennal grooves obviously golden dusted, facial ridges and gena only slightly dusted. Postcranium yellow to yellow-brown, with a light brown area ventrally on bottom portion of postcranium. Adjacent to posterior margin of the eye there is an obvious stripe of golden dusting, remaining postcranium slightly dusted to shining. Postcranium with black setulae. No setulae on a small area adjacent to eye margin and bottom portion of postcranium. Proboscis light brown to yellow. Frontoclypeal membrane small, hardly widened basally, light yellow to light brown and easy to distinguish from the darker clypeus. Palp apically with two black setae. Thorax orange-brown with an almost completely black scutum (but with the margins of scutum orange-brown) and with dark brown spots on katepisternum and anepisternum. Distinct golden dusting on scutum, proepimeron and anatergite. Dusting stripe extending from middle coxa to notopleuron (Fig. 14). Scutum with short black setulae. Scutellum covered with short black setulae and with 2 scutellar setae. 1 notopleural seta and no postalar seta. Postalar callus with 2−3 long black setae and no long curved setulae. 1 black seta and 3 black setulae posterodorsally on katepisternum, no setae ventrally. Wing hyaline to slightly brownish, lacking any distinct marking (Fig. 21). Veins dark brown to yellowish brown. Subcosta contrasting light yellow. Basal medial-cubital crossvein bm-cu white. Wing mainly covered with microtrichia, but with no microtrichia at base of radial cell r 2+3 and basal radial cell br, basal medial cell bm and alula almost completely lacking microtrichia. Discal medial cell dm also basally lacking microtrichia. Upper and lower calypters yellowish white, upper calypter with long white setulae on margin. Haltere yellow to light brown with a slightly darker brown base. Legs yellowish brown. Hind femur slightly darker brown posterodorsally and hind tibia darker brown in apical half. Legs at most with inconspicuous golden to silver dusting. Legs all with short, adpressed black setulae. Hind coxa with 2 strong lateral setae. Pulvilli brownish white. Claws yellowish brown with distinct black tips. Empodium whitish yellow, about as long as pulvilli. Abdomen mainly black (Fig. 14). Tergites 2−5 with an orange-brown posterior margin. Tergites 1−2 laterally orange-brown. Protandrium and epandrium almost completely orange-brown. Abdomen with scattered short black setulae, except tergite 2 lacking setae. ♂ abdomen slightly to distinctly golden dusted in anterior view, with denser golden dusting at hind margins of tergites 2−5 and almost complete dense golden dusting on protandrium. Sternite 4 longer than broad, about 0.2 width of sternite 5, lacking any setulae.
Description of ♂ postabdomen based on one dissected paratype: Epandrium as shown in Fig. 25. Epandrium not fused behind cerci but with a slightly sclerotised connection at both sides of epandrium. Posterior margin of epandrium laterally with long black setulae and a distinctly projecting and strongly sclerotised submedial tooth (Fig. 25: tep). Epandrium distinctly dented-in laterally. No hypoproct evident. Distiphallus shorter than epandrium but distinct, covered with dense microtrichia basally and with two fields of dense black setae distally (Fig. 27). Distiphallus basally with two lateral evaginations of different sizes (Fig. 27: edp), one finger-like, the other one larger and flat. Both are densely covered in microtrichia.
Description of ♀: Abdomen subshining to shining, only tergites 2−5 with an inconspicuously dusted hind margin (Figs 17−18). Maximum width of abdomen is at segment 4. Length: maximum width of tergite 2 = 1.3; length: maximum width of tergite 3 = 1.2. Shape of theca as shown in Figs 20, 22. Anterior surface of theca with long black setulae. Apical half of posterior surface of theca with scattered short blunt spicules, those in the central area in short horizontal pallisade groups but not markedly arranged in long horizontal lines (Fig. 22). Sternite 5 anteriorly lacking an elongation. Sternite 6 almost completely covered with short blunt spicules which are also in short horizontal pallisade groups towards the centre but not arranged in horizontal lines (Fig. 23). Sternite 7 slightly longer than broad, anteriorly rounded and with a line of black setae at posterior margin only.
Variability: Wing length 5.9−7.4 mm. Facial keel can be completely yellow or completely light brown. Postcranium can be completely yellow. Mediotergite can be almost completely black. One female paratype has an almost completely orange-brown scutum with only two black spots. Variable setation: there can be only 1 scutellar seta or scutellar setae may not be separable from setulae on scutellum. There can be 2 notopleural setae, and postalar setae can occur. Subcosta can be less conspicuously lighter than adjacent veins. Basal medialcubital crossvein bm-cu can be brownish. The female abdomen can be almost completely orange-brown.
Diagnosis: As described for the monotypic genus.
Etymology: The species epithet „martini“ is derived from the given name of Martin Hauser.
Distribution: As described for the whole genus.
