description: <i>CITROGRAMMA CITRINOIDES</i> WYATT, 1991 <i>Citrogramma citrinoides</i> Wyatt, 1991: 158. Holotype: &amp;male;, BMNH, by original designation. Type locality: Malaysia: Mt Jasar. Wyatt, 1991: 158, figs 6 and 14. <i>Syrphus variscutatus</i> of Curran, 1928 (in part). <i>Geographical distribution:</i> Malay Peninsula (Pahang), Hainan. <i>Differential diagnosis:</i> Distinct species only known from male specimens. Face yellow, lunule yellow, scutellum yellow, metafemur black and pro- and mesofemur yellow. Very similar to <i>C. flavigenum</i> but <i>C. flavigenum</i> with lunule black, brown macula on facial tubercle, and pro- and mesofemur black basally; both species yellow pilose on notopleuron and on supra-alar area, but <i>C. citrinoides</i> has little black hairs. <i>Citrogramma flavigenum</i> is only known from southern India. <i>Remarks:</i> Little variation was found in the type series and nontype material. The most evident is tergum 3 usually with a yellow fascia with parallel margins, but some specimens have this fascia slightly emarginate posteromedially (Fig. 90). After the study of the type material, I realised that some individuals have pro- and mesofemur with a posterobasal brownish area, but entirely yellow anterobasally. This only posterior diffuse macula is very distinct from the other character state used in couplet 40 of the key: pro- and mesofemur black basally. A male was found labelled as paratype and not noted in the original description (Malaysia, Pahang, Cameron Highlands, 5000–5500 ft, 12.vi.1935, H.M. Pendlebury, BMNH). The paratype male collected on 22.ix.1938 has a head glued on of a different syrphid genus, <i>Allograpta</i> Osten Sacken, 1875. As mentioned by Wyatt (1991), there are some individuals that were identified as paratype or paralectotype of <i>C. variscutatum</i> (Curran, 1928). They are placed in the nontype material. Holotype male deposited in The Natural History Museum, formerly British Museum (Natural History) (London, UK) and labelled: ‘PAHANG, F.M. S./ Cameron Highlands / <i>G. Jasar 5500</i> ft./ <i>25–6</i> –193 <i>5</i> ’ ‘ H.M. Pendlebury. / Coll. / F.M.S.
