CITROGRAMMA FASCIPLEURUM (CURRAN, 1931)

Syrphus fascipleura Curran, 1931b: 352 View in CoL . Holotype: ♂, BMNH, by original designation. Type locality: Malaysia: Mt Kinabalu. Curran, 1931a: 313, 1931b: 352.

Citrogramma fascipleura View in CoL of Knutson et al., 1975: 311; Wyatt, 1991: 155, 158.

Citrogramma difficile View in CoL of Wyatt, 1991 (in part).

Geographical distribution: Borneo.

Differential diagnosis: Citrogramma fascipleurum has a shaped triangular black macula on scutellum, pro- and mesofemur entirely yellow and metafemur black; it is very similar to C. gedehanum and C. difficile . Differences with C. gedehanum and C. difficile are few: facial and notopleural pilosity black, and posterior anepimeron yellow in males. The females of C. fascipleurum have yellow lunule and the posterior anepimeron is yellow ( Fig. 110 View Figures 100–111 ). The distribution of C. fascipleurum overlaps with that of C. difficile .

Remarks: Holotype is not in very good condition with abdomen glued to a label and right wing broken. The female from Mt Dulit, previously identified as C. difficile ( Wyatt, 1991) , is here identified as C. fascipleurum because both specimens share the same pleuron pattern with anepimeron yellow except a dorsal black macula on anterior section. The other morphological character that distinguishes them from C. difficile is the presence of black hairs on notopleuron.

Holotype male deposited in The Natural History Museum, formerly British Museum (Natural History) (London, UK) and labelled: ‘Holo–/type’ [round, red border] ‘ Syrphus ♂ /TYPE/ fascipleurum / Curran / No.’ [red] ‘B.N. BORNEO,/Mt Kinabalu,/Kenokok,/ 3.300 ft. / 22 Apr. 1929.’ ‘Pres. by/Fed. Malay States/ Museum. /B.M. 1934–74’ ‘ Syrphus / fascipleurum / Curran /Det./C.H. Curran’ ‘ Citrogramma / fascipleurum ♂ / (Curran) /K.D. Ghorpade det. 197 9 ’.

Type locality: Malaysia: Sabah (in Borneo), Mount Kinabalu, Kenokok , 1006 m, 6°04′N, 116°33′E GoogleMaps .

Material examined: Type material. Holotype, as above.

Nontype material. MALAYSIA: Sarawak, Mt Dulit , moss forest, 4000 ft, B.M. Hobby & A.W. Moore [1♀, BMNH] .
