Elaphromyia yunnanensis Wang

Elaphromyia yunnanensis Wang, 1990: 489. Type locality Lushui, Yunnan, China.

Material examined: 1♂, INDIA: Arunachal Pradesh, Roing, Kebali, 10.ix.2014, Ramani, S. (UASB).

Diagnosis (Figs 35, 36): Medium-sized (5.91 mm) fly; head as high as long, frons fulvous with three pairs of frontal setae (all black) and two pairs of orbital setae (posterior pair black), ocellar setae well developed, medial and lateral vertical setae, postocellar setae white, lanceolate; postocular setae black interspersed with white lanceolate setae. Face fulvous without any markings; scape, pedicel fulvous, first flagellomere shorter than face, arista short plumose. Scutum dark brown to black with golden yellow setulae except postpronotal lobe, notopleuron and beneath postsutural supra-alar seta. Anepisternum fuscous to dark brown with a single seta, anepimeron concolorous with anepisternum and with a single seta, katepisternum black with a fulvous anterior border and a single seta, anatergite and katatergite partly yellow and black. Chaetotaxy complete; 1 on postpronotal lobe, 1 presutural supra-alar, 1 anterior notopleural, 1 posterior notopleural, 1 postsutural supra-alar, 1 dorsocentral placed in line with postsutural supra-alar, 1 postalar, 1 intra-alar, 1 prescutellar acrostichal seta. Scutellum brown with two pairs of scutellar setae. All leg segments fulvous except hind femur with basal and medial black spots; forefemur with a single row of 6–7 ventral setae. Wing elongate (6.33 mm), parallel-sided and predominantly dark brown with numerous hyaline and subhyaline markings, costal and anal margins predominantly hyaline with faint brown markings, cells r 1 and r 2+3 with very small, closely packed hyaline spots, subhyaline markings appear to be transversely arranged, cell m with 4 prominent hyaline bands from the margin. Abdomen elongate-oval, all tergites dark brown to black with faint yellow markings laterally.

Male genitalia (Figs 37–39): Epandrium broad, with no demarcation between lateral surstylus and epandrium, proctiger smaller than epandrium, apex of lateral surstylus pointed with numerous setae; epandrium and lateral surstyli round (posterior view) with apical extension of surstylus prominent; phallus elongate (4.54 mm) with a sclerotised rod like structure in glans of phallus, vesica as long as phallus.

Distribution: China (Yunnan); India (Arunachal Pradesh: new record).

Remarks: The specimen collected from India is comparatively larger than the type male and has transverse subhyaline markings on the wing and four elongate spots in cell dm, unlike Wang’s (1998) illustration, which depicts round, well separated spots and six prominent spots in cell m. Since only a single specimen is available and considering its overall appearance and dark abdomen, we provisionally regard the Indian specimen as a variant of Elaphromyia yunnanensis; however, further material might show it to be specifically distinct.
