Haltere length 0.8 mm , yellow with knob pale brown. Abdomen ( Fig. 38 ). Tergites brownish yellow. Sternites yellow. Setae on abdomen brown. Hypopygium ( Figs. 43–44 ). Posterior margin of tergite nine slightly emarginate. Gonocoxite with a relatively small and simple ventromesal lobe. Clasper of gonostylus arched at 1/2 length, abruptly narrowed to apical spine. Lobe of gonostylus large; rostral prolongation small, middle with two long and slender spines arising from a small tubercle. Paramere with mesal-apical lobe slender and short, margin microscopically and irregularly toothed, tip relatively blunt. Female. Body length 6.5 mm , wing length 7.2 mm , mouthparts length 2.0 mm. Similar to male. Cercus brownish yellow. Hypogynial valve pale brownish yellow. Tip of hypogynial valve and cercus nearly aligned ( Fig. 41 ). FIGURES 43–44. Geranomyia maculata sp. nov. 43: Male hypopygium, dorsal view; 44: Male hypopygium, ventral view. Scale bar: 43–44 = 0.2 mm. Type material. Holotype male ( CAU ), China : Taiwan , Hualian , Bilvshenmu ( 24°10'48"N , 121°24'01"E , 2200 m ), 2013. VI.6 , Wenliang Li ( light trap ). Paratype : 1 female ( CAU ), same data as holotype . Distribution. China ( Taiwan ) . Etymology. The specific name (from Latin maculatus (adj., meaning"spotted”)) refers to the combined spot at the middle area of cell CuA1 and tip of CuA2. Remarks. This new species is somewhat similar to G. i m m o b i l i s ( Alexander, 1932 ) in having the similar venation of wing and structure of male hypopygium. It can be distinguished by the wing with nine large spots on costal region ( Fig. 42 ) and the tubercle on rostral prolongation of lobe of gonostylus less than one-third of the rostral prolongation ( Figs. 43–44 ), whereas in G. immobilis , the wing has seven spots on costal region and the tubercle slightly shorter than rostral prolongation ( Alexander 1932 ). This new species is also somewhat similar to G. tenuispinosa (Alexander, 1929) in having the similar venation of wing, but can be easily distinguished from the latter by the wing with a combined spot at middle area of cell CuA1 and tip of CuA2 ( Fig. 42 ), and lobe of gonostylus of male hypopygium with a small rostral prolongation and two spines arising from a small tubercle ( Figs. 43–44 ). In G. tenuispinosa , the wing has no spot at the middle area of cell CuA1 or tip of CuA2 ( Fig. 16 ), the lobe of gonostylus has a long and slender rostral prolongation and two spines of which one arises from a small tubercle and the other arises from the rostral prolongation directly ( Alexander 1929a ).
