7639B4066A3B3E137ABABA032E591CCC.taxon	materials_examined	Type locality. China, northern Yunnan, mountain valley 12 km west of Zhongdian (Shangri-La) (D. Král, pers. comm.). Note: The geographic coordinates and altitude given in the locality labels of the type specimens were obtained from an out-dated map and are incorrect (D. Král, pers. comm.). Type material. HOLOTYPE: ♀, ‘ China N Yunnan, Xue / Shan nr. Zhongdian / 4200 m, 24. vi. 1996 / 27,49 N / 99,34 E // collected by / J. Farkač, P. Kabátek / and A. Smetana // HOLOTYPE / Callomyia / triangulata sp. nov. / M. Tkoč det. 2012 ’ (NMPC). PARATYPE: ♀, same label data as the holotype, only third label has ‘ PARATYPE’ instead of ‘ HOLOTYPE’ (NMPC).	en	Tkoč, Michal (2012): A new species of the flat-footed fly genus Callomyia (Diptera: Platypezidae) from South China.

7639B4066A3B3E137ABABA032E591CCC.taxon	diagnosis	Differential diagnosis. Callomyia triangulata sp. nov. differs from C. coei mainly by its thoracic and abdominal colouration. The thorax of C. triangulata sp. nov. lacks the two black postsutural areas above wing bases and the median black stripe is less pronounced in its anterior part. The scutellar black stripe is thinner. Tergites 1 and 2 (T 1 − 2) are yellow with brown markings, not silvery orange as in C. coei. T 3 is yellow with a brown triangular marking, unlike C. coei which has T 3 black. T 4 is mostly brown with small yellow posterior spots, T 5 − 6 are silver with small medial brown spots in contrast to T 4 orange with thin medial stripe, T 5 black and T 6 silver dusted as in C. coei. Other characters in which C. triangulata sp. nov. differs from C. coei are also important to recognize it from other Callomyia species: femur of hindleg is wider than tibia (other Callomyia species have usually tibia wider than femur); wing vein R 1 with 19 short spines (other Callomyia species have usually lower number of these spines). The European, Russian and Far Eastern Callomyia species may be easily recognized from the new species by the abdominal markings, which are composed of bands and dorsally disconnected bands, but never with a triangular marking (CHANDLER 2001; SHATALKIN 1982, 1985, 1992). Moreover, the new species differs from C. admirabilis Shatalkin, 1980 by the presence of spines on R 1, and from C. dorsimaculata Shatalkin, 1982 by presence of a dorsal seta on the middle tibia. Callomyia krivosheinae Shatalkin, 1982 has T 1 − T 4 orange with no brown markings and its T 6 is black. Callomyia triangulata sp. nov. could be recognized from the North American species by its generally bright grey and yellow colour of the body (American species are mostly dull or black coloured) and different abdominal colouration. The only American species which has triangular marking on the abdomen is C. clara Kessel, 1949, but it has the triangle on T 4 instead of T 3 as in C. triangulata sp. nov. Also, the American species of Callomyia have 9 − 16 spines on R 1, not 19 as in C. triangulata sp. nov.	en	Tkoč, Michal (2012): A new species of the flat-footed fly genus Callomyia (Diptera: Platypezidae) from South China.

7639B4066A3B3E137ABABA032E591CCC.taxon	etymology	Etymology. The Latin adjective triangulata (= three angled) refers to the brown triangular shaped marking on the third abdominal tergite of the female, the most conspicuous diagnostic character of the species.	en	Tkoč, Michal (2012): A new species of the flat-footed fly genus Callomyia (Diptera: Platypezidae) from South China.
